Energy Company Obligation Schemes

Alison Thewliss Excerpts

[Wera Hobhouse (Bath) (LD)]

It is a pleasure to serve under your chairmanship, Mr Paisley. I congratulate the hon. Member for Ceredigion (Ben Lake) on bringing this important debate to this place.

We are in the middle of a cost of living crisis. Bills are soaring, wages are not keeping pace with inflation, and people are struggling to make ends meet. We must not forget how harsh last winter was. The energy price cap rose by 54% and many people were trapped in cold, leaky homes. We cannot allow that to happen again.

Households in poorly insulated homes will pay an estimated £13 billion a year more in energy bills. That is because the Government have failed to bring those homes up to at least band C of the energy performance certificate rating. Some 43,000 homes in Bath have a poor efficiency rating, and the Government’s inaction has meant that some of my constituents are more than £1,300 poorer each year.

We are also in the middle of a climate emergency. The UK has some of the leakiest homes in Europe. Insulating our homes would push down energy demand and cut our country’s greenhouse gas emissions. For the past decade, the energy company obligation schemes have delivered warmer homes, cheaper bills and greener buildings for millions of vulnerable households. The ECO4 scheme is the latest iteration. It provides grants to fund energy-efficient upgrades to homes, and pays for loft or cavity wall insulation, new heating systems such as boilers, and other measures designed to increase energy efficiency, as we have already heard.

However, ECO4 installations are not keeping up with the target to improve 450,000 homes by March 2026. The Energy Efficiency Infrastructure Group has shown that, by March 2023, only 15,000 homes had been treated. That is just 3% of the overall delivery target. That is very poor, and an example of the Government’s inaction on delivering what has been promised.

The cost assumptions made in the ECO4 assessment are outdated and unrealistic. The modelling used to set ECO4 targets was based on estimated costs in 2021 prices, with an allowance for general inflation over time. Since that assessment was made, inflation has soared. December 2022 saw inflation having risen by 9.2% in the previous 12 months. That is more than three times what Ofgem projected it to be.

The costs of delivery far exceed what Ofgem has accounted for. Loft insulation is, on average, 430% more expensive, cavity wall insulation is 372% more expensive, and external wall insulation is 147% more expensive. The Government should ensure that those costs are taken into account and must match the cost of measures in ECO4 with inflation. That is the main point that I wanted to make; the 2021 estimates do not take into account the soaring inflation that we have seen over the past year.

The ECO4 criteria restrict the number of homes that can be improved. The eligibility requirements set out that the homes must be improved by at least two EPC bands, which makes it hard to find suitable homes. Energy Efficiency Infrastructure Group members estimate that 90% of qualifying homes miss out because they are unable to meet the minimum requirements of the scheme. To illustrate my point, E.ON attempted to deliver energy-efficiency measures to a three-bed mid-terrace property in Dagenham. The owners of the property qualified for ECO4 as their home was rated EPC band E and they were living in fuel poverty. The package of measures that E.ON proposed would have saved the family about £600 a year on their energy bill, but the installation was rejected because the measures would not improve the house enough to make it jump two EPC bands.

When it comes to tackling the climate and cost of living crises, every little helps, so why is the ECO4 scheme making perfection the enemy of the good? The Government should relax the minimum requirements when all reasonable measures have been installed in an eligible household. That would ensure that vulnerable households could still receive much-needed support. To tackle the cost of living and climate crises, we must improve the energy efficiency of our homes. We must do all that we can to ensure that the ECO scheme benefits as many people as possible, as soon as possible.

[Alison Thewliss (Glasgow Central) (SNP)]

The hon. Lady is making some excellent points. I am sure that in her constituency, as in mine, there are many older properties that are very difficult to convert. Does she agree that more needs to be done to ensure that those households can access the scheme, because it is harder for them to convert their house?

[Wera Hobhouse]

Absolutely; I could not agree more. In Bath, we have a lot of old, leaky homes. They are very beautiful, but they are not particularly energy efficient. People really want to do something, but ECO4 does not work for a very large number of households. If we really want to help vulnerable people and tackle the climate emergency, we must look at how the scheme has been designed and make some improvements to it. The two-jump requirement is particularly difficult in old properties.

The Government must take urgent action and improve ECO4, in order to protect the most vulnerable from cold winters and tackle the climate emergency as soon and as effectively as possible.
