Energy Company Obligation Schemes

Debate between Dan Poulter and Ben Lake

Tuesday 27th June 2023 Westminster Hall

[Ben Lake]

I am very grateful to my right hon. Friend for that important intervention and you will be unsurprised, Mr Paisley, to hear that I agree with her that there is an important opportunity to introduce emergency measures. At the end of the day, energy companies are making eye-watering amounts of profit at a time when households across the country are struggling. I think it is very appropriate for us to consider ways of recouping some of that potential income to put against this important measure.

Adjustments are required to get the scheme back on track so it can achieve its full potential. The first adjustment requires the UK Government to look again at ECO4’s cost assumptions. They were finalised in April 2022 and do not reflect current market conditions, including the escalation in costs caused by labour shortages and manufacturing prices. More recent cost assumptions, such as those included in the Great British insulation scheme’s impact assessment, reflect those price increases.

For example, the fixed assumed costs of installing external solid wall insulation, which comprises 12% of measures installed under ECO4 to date, increased from £4,200 in 2021 to about £5,000 in 2022—by almost 20%. Meanwhile, the UK Government estimate that the cost of installing cavity wall insulation for bungalows, as well as detached, semi-detached and end-of-terrace houses, has increased by 50% to 63%. That is all without factoring in the inflationary pressures we have seen in 2023 so far. At the start of 2023, insulation and associated material prices increased significantly, many by close to 10% and some by as much as 35%, compounding similar increases seen last year.

Another aspect of the scheme that requires attention is the minimum requirements threshold, which means that a household’s energy performance certificate must be improved to a particular level. For example, if band D and E homes are to be eligible for the scheme, they have to be upgraded to at least band C, and band F and G homes must be upgraded to at least band D. We should welcome the intent of that requirement. Providing support to the poorest households in the least efficient homes by bringing them up to a significantly higher energy performance rating is an important objective. Nevertheless, the requirement is proving to be a limiting factor on the scheme’s delivery. I have spoken to installers and energy suppliers who say that the minimum requirements are too inflexible compared with previous schemes.

It is suggested that the requirements are making it difficult to find eligible properties, and installers are reporting difficulties in proving how properties in higher EPC bands, such as those in band D, as well as on-gas properties, can meet the requirements. E.ON Energy estimates that around 90% of qualifying fuel-poor households cannot have works delivered to their properties, as either they fail to meet the minimum requirements threshold or it would be economically unviable to upgrade them to the levels required to meet it.

[Dr Dan Poulter (Central Suffolk and North Ipswich) (Con)]

The hon. Gentleman is giving one of the best speeches I have heard in Westminster Hall in a long time, and he has some good evidence to back up his comments. I congratulate him on securing the debate. My constituency, like his, has a high number of rural homes. Many are reliant on oil-fired central heating and also struggle to fit into the qualifying criteria for the type of scheme that he has outlined. What advice does he have for the Government on how we can improve the flexibility of the schemes to ensure that oil-fired homes can qualify?

[Ben Lake]

The reality is that a very high proportion, if not the majority, of homes in rural constituencies find it difficult to access the scheme because they are not on the mains gas network. In my constituency, some 72% of properties are not connected to mains gas and they are struggling uphill to get on to the scheme. The Government would do well to look again at whether we can change the ECO Flex pathways to allow local authorities greater flexibility to support off-grid properties in particular. That might be a way forward. We certainly need to address the issue. If we do not, I worry that rural areas, which often have an older, less efficient housing stock, will be left behind. I am grateful to the hon. Gentleman for making that important point.

As greater investment is required per property to meet the minimum improvement threshold requirements, the current iteration of the scheme appears to be more exposed, and therefore more vulnerable, to the inflationary pressures that I mentioned earlier, so we need to look again at how it is funded. I ask the UK Government to look at that very carefully.

Another aspect of ECO4 that is welcome in principle, but which is putting pressure on those delivering the scheme, is the Flex pathway. The pathway is important, because it enables local councils to identify low-income households that are in need of support, but that are unlikely to be eligible under the scheme’s standard approach. It also provides an opportunity for local councils to better tailor energy efficiency schemes to their respective areas, and I refer back to the remark from the hon. Member for Central Suffolk and North Ipswich (Dr Poulter) about rural properties. The issue, however, is that local councils feel that the Flex pathway is too onerous and that the information required of them for each application takes up significant staff time and resources. Indeed, I am told that the level of detail required can make the Flex pathway inflexible when considering different local factors.

One of those factors is the nature of the housing stock in an area, and I have already mentioned that Wales has some of the oldest and least efficient housing stock in western Europe. I spoke to representatives of Gwynedd Council, who expressed concerns that the products available via ECO do not always work well with the design of older houses.
