The Economic Secretary to the Treasury (Rachel Blake)
I beg to move, That the Bill be now read a Second time.
The conflict in the middle east has left British families and businesses exposed to volatile gas prices, which has made things more expensive for those who drive for work, including care workers. Even though much of the country’s electricity comes from cheaper renewables and nuclear, electricity prices are still largely set by gas, which means that running a wash, turning on the lights or boiling the kettle has also become more costly for families across the UK. As my right hon. Friend the Chancellor set out in May, the Government are keenly aware of the costs that the conflict in the middle east will impose on British people. The Government have taken steps to put our economic security and national security first. The Chancellor has committed to doing what she can to support families and businesses; to being responsive to a changing world; and to being responsible, in the national interest.
Some legacy renewable energy generators stand to benefit from the disparity when higher gas prices determine the price of electricity. Without any new costs or risks, those generators receive extraordinary revenues. The electricity generator levy already recoups some of the excess returns made by renewable generators when electricity prices are over £82.61 per MWh, but the Government have decided to increase the rate of the levy from 45% to 55% from today, 1 July.
The rate rise will have two main benefits. It will ensure that a larger proportion of any exceptional revenues from high gas prices are passed back to the Government. That will provide a vital revenue stream, so that money is available to the Government to support businesses and families with the impact of the conflict in the middle east. In the longer term, the increase in the EGL rate will also encourage participation in the new voluntary contract for difference scheme, announced in April—part of a broader package of measures that break the link between electricity and gas prices. Importantly, new investment is excluded from the levy. This ensures that the measure is targeted solely at legacy windfall returns, and does not deter future clean energy development.
In March, the Government announced a review of mileage rates for employees who use their own vehicle for work, and for the self-employed who use the simplified expenses rates. In recognition of the pressures facing drivers as a result of the conflict in the middle east, my right hon. Friend the Chancellor announced in May the first uprating of mileage rates in 15 years. It was backdated to April, to provide immediate support to both groups. Mileage rates will increase for 2026-27 from 45p to 55p for the first 10,000 miles and 25p thereafter, with effect from 6 April 2026.
My hon. Friend is making an excellent speech. This is fantastic news for my constituents, my farmers and my businesses. Does she welcome the statement from the End Fuel Poverty Coalition, which said that increasing the rates of approved mileage allowance payments is absolutely the right thing to do right now?
Rachel Blake
I thank my hon. Friend for his thoughtful intervention. I absolutely agree that this will make a real difference to those workers who drive for their work. This is a long overdue measure, and I am very happy to put the Bill forward today.
The proposals represent the largest ever increase to the mileage rates, benefiting around 2 million employees and 1 million self-employed individuals, and saving over £120 a year for a worker doing 6,000 business miles. Looking beyond 2026-27, the Government have already committed to a review of the rates, and will set that out at the Budget.
Recognising the key role that the road haulage sector plays in transporting goods across the UK, and its disproportionate exposure to fuel costs, the Government are introducing a 12-month holiday from vehicle excise duty for the majority of heavy goods vehicles for licences taken out between 1 July 2026—today—and 30 June 2027. That will save a typical HGV £600, on top of savings from fuel duty. Fuel costs make up a substantial proportion of HGV operating costs, and this action will help prevent cost pressures arising from the conflict in the middle east spreading across the economy.
The announcements on mileage rates and HGV VED were part of a wider package of measures announced in May, including on fuel duty. In total, the decisions taken since the 2024 general election to freeze fuel duty will save motorists 11p per litre, or £120 for the average car, £250 for the average van and over £2,000 for the average HGV, compared to previous plans. For those reasons, I commend the Bill to the House.
The Exchequer Secretary to the Treasury (Dan Tomlinson)
Today’s debate is progressing rapidly—so rapidly, in fact, that I am yet to turn to the speech in my folder. It is a privilege to close this rapid debate on behalf of the Government, and I thank Members for their contributions, as well as the Economic Secretary to the Treasury for opening the Government’s arguments. She was right to point out that the conflict in the middle east has imposed additional costs on the British people, which is why the Chancellor and the Prime Minister have been careful throughout the conflict—from the beginning, when other parties took a different approach—to tread carefully, be cautious and not rush to entangle ourselves in a foreign conflict, risking national security and potentially further harming our economic security.
The measures we are considering are an example of how the Government have responded in a proactive and positive way to the impact of the conflict in the middle east on households, families and businesses. Reasonable people can disagree about how the Government could have best responded to the conflict as it played out. It is this Government’s judgment that we have taken the right approach to ensure that we support those families and businesses that most need it. We have been there for them with the changes in this Bill and others—either already passed or making their way through the House via instruments of some form—such as continuing the freeze in fuel duty.
We wanted to ensure that our response was proportionate and targeted so that we could continue on the path that this Government have set out to bring down the deficit and bring down borrowing sustainably over the course of this Parliament. This year, for the first time since the 2000s, we have a lower deficit than the G7 average—something that the Conservatives never managed to achieve, despite all their talk about wanting to manage the public finances well.
I will not run through the measures in detail, as my hon. Friend the Economic Secretary to the Treasury has already done so. Instead, I will take the chance to respond to the questions asked by Opposition spokespeople.
I can confirm that the consultation on the electricity generator levy will come before the end of this year. It is being worked on at the moment by officials in the Department for Energy Security and Net Zero. We will ensure that we consult on this at the end of the year. Questions such as auction allocation and details of the way the wholesale contracts for difference will work will, I am sure, be raised in the consultation or elsewhere in engagement.
Given that the levy kicks in from today and the Minister said that the consultation will be published before the end of the year, six months henceforth, and then legislation will have to go through, are the Government considering any backdating provision? If a company generator wanted to go into one of these wholesale CfDs, doing so would allow it to have that backdated; at the moment, it would not have the option to go into the wholesale and will just be hit with the higher levy.
Dan Tomlinson
No. If prices are slightly above the threshold set in the electricity generator levy, as they are at the moment, I believe, those taxes will be due now, from 1 July, whether or not businesses make decisions down the line after the consultation, after engagement and after the detail of the wholesale contract for difference policy has been set out by the DESNZ Secretary of State.
Both the shadow Exchequer Secretary and the hon. Member for St Albans (Daisy Cooper) asked how much revenue will be raised by this and other measures. It is a good tradition—a tradition set in place, in fact, by the Conservatives and Liberal Democrats—that the Office for Budget Responsibility set out the costings of policy decisions when they are made. That is important. This Government and this Chancellor have been keen to protect the independence and integrity of the OBR, rather than throwing it under the bus and causing market turmoil, as Liz Truss did. At the Budget later this year, the OBR will, in the usual way, confirm the costings of the changes announced by the Chancellor and included in the Bill.
The shadow Exchequer Secretary is right that the costings the OBR put out initially on the EGL ended up being very different from the revenue that it has pulled in. That is why it is right that we have an independent forecaster, so that even if things materialise differently than was forecast, we have forecasts that are robust to the information at the time and can be relied on by all.
The hon. Gentleman questions whether the Government have provided sufficient support more broadly. I would just mention that we have taken the decision to extend the fuel duty freeze. Going into the general election, the previous Government’s plan, as set out by the OBR, which we have already talked about, was for fuel duty to continue to rise and for the 5p cut to unwind. I believe that motorists would be paying a further 11p of fuel duty if it was not for their choice in 2024 to elect a Labour Government and not go ahead with the plans that the Conservatives set out.
A couple more points have been raised. The shadow Minister mentions a review of indexation. We will, of course, keep the mileage rates under review. The Chancellor announced a few weeks back that we will have a review. We have somewhat pre-empted that with this 10p increase, because we wanted to respond to the conflict in the middle east and the impact on households, but that review is still ongoing and will report if further changes are to be made to the policy at the Budget.
The Liberal Democrat spokesperson made the important point that many care workers and people who drive for work may be working for an employer who does not provide a mileage rate. It is not compulsory for employers to set the rate at the HMRC rates. We have increased rates from 45p per mile to 55p per mile up to 10,000 miles, and I encourage employers across the country to adopt that higher rate.
For employees who work for an employer who does not do so or who persists in having a significantly lower rate, as I am aware that some do, it is possible to claim back marginal tax up to that amount, so 55p per mile now. A basic rate taxpayer can in effect get 20% back on that. It was a pleasure to meet care workers and members of Unison, the trade union, a couple of weeks ago at No. 11 Downing Street. Some questions were raised about whether that process could be made any easier for workers to navigate, and that is something I certainly want to look at with my officials. This is a complex area of policy. I encourage Members to inform care workers and others who drive for work and who do not have mileage rates provided by their employer that they can claim the tax back from HMRC.
I hope that responds to many of the points made.
I think the Minister might be coming to a conclusion, and I would not want him to miss the opportunity to refer to the House of Lords Constitution Committee and the presumption that fast-tracked legislation should include sunset clauses. Could he explain why the Government have chosen not to follow that guidance in this case?
Dan Tomlinson
There is a very sensible policy rationale when it comes to the electricity generator levy, which I think is the clause the hon. Member is referring to. We want to ensure that the ending of the EGL and the future decisions made on it are made in the light of the decisions that will be made on the wholesale contracts for difference, which, as I have said, are coming forward. It would not have been the right decision to pick a future end date without considering how it would interact with the decisions that the Government will make and will be consulting on later this year on the detail of the wholesale contracts for difference.
I hope that that has responded to many, if not all, of the points that have been raised by Opposition Members. I encourage Members to support the Bill.
Question put and agreed to.
Bill accordingly read a Second time.

The Financial Secretary to the Treasury (Lord Livermore) (Lab)
My Lords, it is a pleasure to open the Second Reading debate on the Taxation (Energy and Vehicles) Bill. The measures contained in the Bill will support businesses across the UK as they deal with the immediate economic costs associated with the ongoing conflict in the Middle East. We did not start this conflict and we did not join it, but it is impacting our economy, including by putting pressure on energy markets and disrupting supply chains.
Despite these pressures, the latest economic data shows that the Government’s economic plan is working. Inflation last month held steady. Britain’s economy was the fastest growing in the G7 for the first quarter of this year. Borrowing is forecast to fall in every year of this Parliament and wages are continuing to rise.
However, as the Chancellor has said repeatedly, we must continue to be responsive to a changing world and responsible in the national interest. That is why we have taken action to support businesses and families, including by reducing VAT on summer activities from 20% to 5% and extending the 5p fuel duty cut until the end of the year, saving the average motorist £120 since last year. We have committed more than £50 million to help those struggling with the cost of heating oil. To support hauliers and farmers, we have cut red diesel by more than one-third until the end of this year. To help reduce costs for energy-intensive firms, we have expanded the British industry competitiveness scheme to more than 10,000 manufacturers. We are also providing targeted support to the chemicals and ceramics industries, protecting thousands of jobs and putting businesses on a secure footing for the long term.
The measures contained in this Bill go further to protect consumers and help firms deal with rising prices. It covers three areas: the energy generator levy, mileage rates and vehicle excise duty for heavy goods vehicles.
On the first measure, the electricity generator levy, the price of energy has risen since the war in Iran began, benefiting generators whose costs bear no relation to the price of gas. The Government’s objective is to ensure that those who benefit from these increased prices and volatility pay their fair share. That is why, in our first Budget, we extended and increased the energy profits levy. Last year, the Chancellor announced a new permanent windfall tax regime on oil and gas.
In April this year, we went further still by announcing an increase to the rate of the electricity generator levy and extending it beyond its original sunset date of 2028. The electricity generator levy recovers excess revenues made by generators that do not use gas when electricity prices are over a long-term average. To ensure that it does not disincentivise investment, any new investment since 22 November 2023 is exempt from the levy. The increase in the main rate of the levy from 45% to 55% is legislated for in this Bill. The extension will be legislated for separately. The Government will set out the fiscal impact of this increase at the Budget in the autumn, with the costing certified by the OBR in the usual way.
Raising the rate will help break the link between electricity and gas prices. Even though the UK is generating more electricity from sources such as nuclear and renewables, international gas prices still set the price of our electricity. This means that, when global gas prices spike, so do bills here in the UK.
By breaking the link between gas and electricity prices, we can help to insulate consumers from the volatility of future crises. The rise in the electricity generator levy will contribute to this by encouraging participation in the wholesale contracts for difference scheme. Currently, under a separate scheme known as contracts for difference, some electricity suppliers are guaranteed a stable, fixed price for the electricity that they produce. The new wholesale contracts for difference scheme will offer certain existing eligible generators that are not already signed up to contracts for difference the option to bid for a fixed price for the electricity that they generate.
Increasing the rate of the energy generator levy will therefore increase the appeal of a fixed rate under the new wholesale contracts for difference scheme, in turn helping to protect consumers from volatile gas-linked electricity prices. The Department for Energy Security and Net Zero will come forward later this year with a consultation on the wholesale contracts for difference scheme. The design of the post-2028 energy generator levy will be considered alongside this consultation.
The second measure contained in the Bill relates to mileage rates. As fuel prices have risen, so has the cost of filling up a car or van for those who drive for work. Despite this, mileage rates—the amount that workers are reimbursed for every mile they drive—have not changed since 2011. This has created a significant gap between the amount it costs to run and maintain a vehicle and the amount that workers are reimbursed for.
In recognition of these pressures, the Chancellor has announced the largest ever increase to mileage rates and the first uprating in 15 years. As a result, mileage rates have now increased from 45p to 55p for the first 10,000 miles. Beyond 10,000 miles, the rate will remain at 25p. This change will benefit employees using their own vehicle for work and those who are self-employed and use simplified expenses rates.
The increase came into effect on 6 April and the legislation before us gives statutory effect to this change. Overall, the increased rate will benefit around 2 million employees and 1 million self-employed individuals, saving over £120 a year for a worker doing 6,000 business miles.
Although employers are not required to reimburse at the new rates set out, if employees are reimbursed below the tax-free rate they can claim mileage allowance tax relief directly from HMRC. More widely, in March, the Chancellor announced a review of mileage rates as a whole. This review is ongoing and will inform the Budget this autumn.
The third measure in the Bill concerns vehicle excise duty on heavy goods vehicles. The road haulage sector plays a vital role transporting goods across the UK, but haulage firms are disproportionally exposed to higher fuel costs. That is why we are providing additional targeted support for the sector through the Bill, with a 12-month holiday from vehicle excise duty for the majority of heavy goods vehicles.
Eligible vehicles renewing their VED in this period will pay a reduced annual rate of £1. This will save a typical HGV £600, and those with higher liability will, in some cases, save more than £900, on top of savings from fuel duty. It will benefit around 46,000 UK-based road freight firms. Taken together with other freezes to fuel duty since the general election, the average HGV has saved over £2,000 compared with plans set out by the previous Government.
This Government have the right economic plan to deliver secure and resilient growth in a changing world, but as we have seen, including over recent days, the war in Iran continues to create uncertainty and volatility in the global economy, and therefore higher costs for businesses here in Britain. The Government have responded by providing immediate support to help with those additional costs, including through the measures contained in the Bill.
These measures will ensure that electricity generators that benefit from increased prices pay their fair share. They will support around 2 million employees and 1 million self-employed people who need to drive for work. They will deliver targeted help to the road haulage sector, ensuring that HGVs remain on the road to deliver food and other products to communities right across the country.
The Bill shows that, in the face of global pressures, the Government will continue to be responsive to a changing world and responsible in the national interest. I beg to move.
My Lords, this Bill is presented by the Government as a series of targeted measures designed to address a specific issue: the war in the Middle East. I thank the Minister for his full explanation. However, the truth is that what we are discussing is a series of sticking-plaster measures designed to curb some of the worst excesses of what can be described only as an economy seriously in trouble.
The current Government—and, indeed, the one that is to come under the leadership of Andy Burnham—face a deeply serious situation. Last week, the Office for Budget Responsibility warned in its Fiscal Risks and Sustainability report that, without action, public debt is set to move on to an unsustainable upward path in the near future.
A key finding is that early action to head off difficult fiscal outcomes is much less costly than late action. This is partly due to the sheer scale of our national debt. Last year the Government borrowed £129 billion, 80% of which was spent on debt interest in an increasingly jumpy bond market. The OBR estimates that an additional £28 billion a year will be needed to meet the Government’s critical pledge to spend 3.5% of GDP on defence. At the same time, spending on the state pension and on health is projected to rise sharply in the next few years —one of the reasons why I called for a cap on expenditure on pensions as a percentage of GDP in my independent review of the state pension age as long ago as 2022 and why I deplore the failure to hold a full House of Lords debate on the 10-year plan for the NHS.
The Lords Economic Affairs Committee said much the same about the unsustainability of debt years ago in its report National Debt: It’s Time for Tough Decisions. The then chair, my noble and far-sighted friend Lord Bridges of Headley, was quoted at the time as saying that
“our national debt risks developing on an unsustainable path”.
Moreover, we are now spending more on welfare, £334 billion, than we collect in income tax, £331 billion. The new Prime Minister and Chancellor of the Exchequer face the choice of either significant tax rises or deep spending restraint if we are to stop debt spiralling further out of control. Yet the OBR has also made clear that tax rises cannot simply be treated as a limitless answer. Continually increasing taxes risks creating ever greater economic distortions, with the Laffer curve biting into receipts—for example, if the top rate of income tax goes up. Wealth taxes raise less than expected, as we know from overseas experience, and they certainly damage competitiveness. Further stealth taxes on earnings risk weakening work incentives and drag more people out of the labour market.
The key to squaring the circle, as I have discussed with the Minister on many occasions, is growth, particularly per capita growth or higher productivity. EU growth has been sluggish. Yet the Government want to get closer to the EU and agree to a package of changes that will certainly cost hundreds of millions a year, given the difficulties of negotiating with the EU, with no certainty that it will improve our economy to the extent hoped. I am also concerned about the impact on our legally binding obligations under CPTPP and our agreements with the US, particularly on vehicles, which I will come to later, and on pharma—agreements that are vital to UK growth. What is the nature of the legal advice that the Government are relying on in saying that they will continue to deliver such international obligations once a revised TCA is agreed?
The Government’s assault on business—rises in national insurance, business rates, and dividend and capital taxes, and the Employment Rights Act—is already having exactly the effect on business that we forecast, with employment squeezed and a crash in economic optimism and enterprise. A report this week from accountants BDO showed that business activity dropped sharply last month after a brief rebound earlier this year ran out of steam. The truth is that there is a deeply serious situation facing Mr Burnham, and we cannot divorce our discussions today from this backdrop.
That brings me on to today’s Bill. Increasing mileage payments to 55p for the first 10,000 business miles is a measure we support. It is right that workers who use their own vehicles for work, including carers, should not be left to absorb rising motoring costs. I know that the announcement was the early fruit of an ongoing review, as the Minister explained, but can he tell us about the logic behind the difference in treatment for hard-working carers and others who drive more than 10,000 miles a year?
I turn to the HGV excise duty holiday. HGV duty had been frozen since 2014 until Labour came into office. While reducing it to £1 for a year will provide some welcome relief to the sector, it does not solve the problem, and Ministers should not overstate the impact. More than 95% of road haulage firms are small businesses operating on tight margins. The Government say the measure will save around £600 for a typical lorry and £900 for the largest vehicles, yet, to put it into context, filling a single HGV at peak prices can cost more than £1,000. This does not offset the wider pressures that the Government have imposed through higher business rates, transport taxes and fuel duty, with duty and VAT receipts of course rising whenever petrol prices spike. If the Government are serious about supporting businesses in this country, and particularly small businesses, they must consider this policy as one of a series of changes they must make to create a tax and economic environment that backs business, especially small business, rather than penalising it.
I turn now to the electricity generator levy. This was introduced under the last Government as a temporary windfall tax and a short-term response to exceptional circumstances. It was due to end in 2028. However, we now see the Government proposing to increase the rate from 45% to 55% and to extend it beyond 2028 with no end date. The case put forward by the Government is that the increased rates will support the decoupling of gas prices by incentivising generators into voluntary wholesale contracts for difference. However, while the new higher levy applies from today, those new contracts are yet to be seen. I believe the proposed strike price is not known. The likelihood of generators accepting them is therefore unknown and in question, and the value for money for taxpayers is yet to be proven.
Moreover, the HMRC impact note for this Bill contains no figures for the Exchequer impact. We should have that, ideally now or at least during the consultations that the Minister referred to. Rather than acting to lower energy costs by taking sensible steps to increase the supply of energy, such as utilising our resources in the North Sea and moving forward with Jackdaw and Rosebank, the Government seem to be using tax as a long-term lever to alter the incentives faced by generators.
We introduced a short-term, emergency measure with a clear sunset date. Sunsetting is a responsible approach to temporary taxation and short-term regulation, and I think it can be very useful. It helps to avoid the accumulation of too much regulation, and I know the Minister worries about unjustified accumulation because it can have an adverse effect on productivity. Sunsetting has the merit of allowing periodic parliamentary scrutiny and of encouraging officials to think creatively about other routes to a desired end. Instead, the Government appear to be moving to a long-term, final answer when the relevant contracts for difference parameters are unknown and untested.
Before the Minister asks, as he sometimes does, what we would do, the Official Opposition have been clear that we would cut bills for businesses and consumers through our cheaper energy plan. We would take VAT off energy bills, axe the carbon tax and legacy subsidies, and again use our resources in the North Sea as the Norwegians are doing. Tax cannot and should not be the long-term solution to the problem of affordable energy.
At this juncture I might remind the Minister of the OBR’s warning. It also agrees that tax cannot be the solution to all this. As we can see on page 81 of its report, there is a significant fiscal cost to the commitment to reduce carbon emissions to net zero by 2050 due to the loss of revenues linked to such emissions. This is particularly true of fuel duty, with three-quarters of the decline in revenue due to the transition to electric vehicles. This is a good example of the difficulties the Government face in relying so heavily on taxation to finance spending.
This Bill contains measures that in isolation are not without merit, but they must be seen for what they are: limited interventions against a backdrop of rising costs, weakening confidence and increasingly strained public finances. Temporary relief has its place but is no substitute for a serious growth strategy, a competitive tax system, disciplined public spending and an energy policy that brings costs down by increasing supply rather than by reaching for higher taxes. That is the test by which this Bill should be judged.
Lord Livermore (Lab)
My Lords, it is a pleasure to close this Second Reading debate on the Taxation (Energy and Vehicles) Bill. I am very grateful to the select group of noble Lords for their contributions and questions.
The measures contained in the Bill will support businesses across the UK as they deal with the immediate economic costs associated with the ongoing conflict in the Middle East. We did not start this conflict and we did not join it, but it is impacting our economy, including by putting pressure on energy markets and disrupting supply chains. That is why, as the Chancellor has said repeatedly, we must continue to be responsive to a changing world and responsible in the national interest.
The noble Baroness, Lady Neville-Rolfe, once again unfortunately sought to talk down Britain’s economy, yet the latest economic data shows that inflation in the UK held steady while it rose in other comparable countries. The noble Baroness and the noble Lord, Lord Redwood, spoke about economic growth, but they did not mention that Britain’s economy was the fastest growing in the G7 for the first quarter of this year. The noble Baroness also spoke about debt borrowing being forecast to fall in every year of this Parliament.
The measures contained in the Bill cover three areas: the electricity generator levy, mileage rates and the vehicle excise duty for heavy goods vehicles. The noble Baroness seemed keen to talk about almost anything other than the measures contained in the Bill, but when she did focus on them, she said that they were just short-term measures, a point also made by the noble Earl, Lord Russell. I disagree; the measures contained in the Bill will provide important immediate support to families and businesses as they deal with the consequences of the war in the Middle East, including the largest ever uprating to mileage rates and a significant reduction in the vehicle excise duty for haulage firms. The increase to the electricity generator levy also forms part of a wider long-term strategy to delink gas from electricity prices, helping to shield consumers from the impact of volatile prices. However, as I set out in my opening speech, the measures form just one part of the wider support we are providing to households and businesses, and we stand ready to go further where necessary.
The noble Baroness also asked about North Sea oil and gas. She knows that I agree with her that North Sea oil and gas production is an important and valuable resource and its workforce is a vital asset to our country. That is why we are harnessing our domestic supply by managing existing fields for their entire lifetimes, including by allowing tie-backs for those fields to ensure that they remain viable.
The first measure in the Bill concerns the electricity generator levy. The price of energy has risen since the war in Iran began, benefiting generators whose costs bear no relation to the price of gas. The Government’s objective is to ensure that those who benefit from these increased prices and volatility pay their fair share. That is why we are delivering an increase to the rate of the electricity generator levy from 45% to 55% and extending it beyond its original sunset date of 2028. Raising the rate will ensure that a greater percentage of exceptional generator revenues is made available to support businesses and households, and it will help break the link between electricity and gas prices by encouraging participation in the new wholesale contracts for difference mechanism.
The noble Baroness asked about the end date. The Government plan to extend the electricity generator levy beyond 2028 to encourage participation in the new contracts for difference mechanism and therefore provide more certainty to firms by offering a fixed price for the electricity they produce. We will work closely with industry to design the post-2028 electricity generator levy regime. DESNZ is planning to publish a consultation on the new contracts for difference mechanism later this year. The design of the electricity generator levy will be considered alongside this consultation.
The noble Lord, Lord Redwood, criticised the Government’s energy policy overall. My noble friend Lord Whitehead set that out, in probably greater detail than I can, in answer to the noble Lord’s question in the previous debate today. As the noble Lord knows, in this country we are particularly exposed to volatile gas prices, not least because the previous Government failed to invest in renewables. We need to invest in an economy that is as low carbon and based as little on gas as possible. By delinking from gas, a key part of the measures contained in the Bill, we can help to separate the price of electricity from the volatile price of gas internationally.
The noble Lord, Lord Fuller, said that we would increase the cost of electricity, but I believe that helping to delink from gas will do the exact opposite. The noble Lord also said that these measures would disincentivise future investment. They clearly will not do that, because the electricity generator levy has strong protections for new investment after 2023, which is exempt from the levy. The electricity generator levy is levied only on legacy renewable generators who stand to make extraordinary profits when high gas prices set the wholesale price without any commensurate increase in costs.
The noble Baroness, Lady Neville-Rolfe, asked about the wholesale contracts for difference scheme. Businesses have welcomed the announcement of the scheme and the certainty that these contracts will provide them with for years to come. The chief executive of the CBI said:
“If implemented correctly, voluntary contracts for difference could reduce the impact of gas on retail electricity prices and ensure the benefits of clean power can be realised across the economy”.
It is right that we now work closely with businesses on the detail, which is why they will have the opportunity to respond to the consultation that DESNZ is planning to run later this year.
My noble friend Lord Sikka asked a series of questions, which I will look at in greater detail. I will write to him, if I am able to do so.
The second measure contained in the Bill relates to mileage rates. I am grateful to the noble Lords, Lord Redwood, Lord Fuller and Lord Altrincham, the noble Earl, Lord Russell, and the noble Baroness, Lady Neville-Rolfe, for their support for this measure. As fuel prices have risen so has the cost of filling up the car or van for those who drive to work. Despite that, mileage rates have not changed since 2011. In recognition of these pressures, the Chancellor has announced the largest ever increase to mileage rates and the first uprating in 15 years.
The noble Baroness asked how the Government determined these uprated rates. In determining them, the Government considered the need to respond to the effect of the war in the Middle East on fuel costs after a prolonged period with no change, while balancing support for individuals with overall fiscal responsibility. She asked about the 25p rate. Our objective has been to focus support where costs are highest. The vast majority of drivers travel fewer than 10,000 miles a year. The 25p rate above 10,000 miles reflects the fact that the marginal cost of driving falls as mileage increases, with fixed costs such as insurance, servicing and depreciation covered by the higher 55p rate. Petrol and diesel motorists, including those who use their own vehicle for work, will also benefit from the extension of the 5p fuel duty cut to the end of this year.
The noble Lord, Lord Fuller, mentioned indexation. The decision the Government have taken on mileage rates is a targeted response to current cost pressures. The review announced by the Chancellor in March will consider the rate beyond 2026-27. Annual indexation is not currently the Government’s policy. The Government have already committed to a review of these rates and will set that out at the Budget.
The noble Earl, Lord Russell, asked about communicating to care workers. As he may know, the trade union UNISON has warmly welcomed this measure. I believe that we will communicate actively to its members.
The third measure contained in the Bill is the vehicle excise duty on heavy goods vehicles. The road haulage sector plays a vital role in transporting goods across the UK, but haulage firms are disproportionately exposed to higher fuel costs. That is why we are providing additional targeted support for the sector through the Bill, with a 12-month holiday from vehicle exercise duty for the majority of heavy goods vehicles. The noble Earl, Lord Russell, also asked about the power to extend this measure further, beyond one year. That would be perfectly possible in future Finance Bills and would not require any additional primary legislation.
The noble Lord, Lord Redwood, asked about smaller vehicles, not just HGVs, being included in this. Van drivers, for example, will benefit from the decision we have taken to extend the 5p fuel duty cut to the end of this year. Those who use their own vehicle for work will also benefit from the mileage rates increase in the Bill; that includes the 163,000 van drivers who are currently estimated to be claiming simplified expenses. It is right, though, that the Government balance direct support for firms with overall fiscal responsibility. Extending these measures to vans would cost an estimated £1 billion to £1.5 billion a year, but we will continue to keep this issue under review.
The noble Baroness, Lady Neville-Rolfe, asked about the impact of other taxes. Typical HGVs will save £600, while HGVs with higher vehicle emissions will save £912. In total, the decision taken since the general election to freeze fuel duty will save the average HGV over £2,000, compared with the previous Government’s plans.
This Government have the right economic plan to deliver secure and resilient growth in a changing world. The war in Iran continues to create uncertainty and volatility in the global economy and, therefore, higher costs for businesses here in Britain. The Government have responded by providing immediate support to help with these additional costs, including through the measures contained in the Bill. The Bill shows that, in the face of global pressures, the Government will continue to be responsive to a changing world and responsible in the national interest.
