ECO4 in Leeds & West Yorkshire

The Energy Company Obligation, phase 4 (ECO4) is the current iteration of a long-running government obligation on large energy suppliers. Suppliers have to fund energy-efficiency improvements in a set number of low-income and fuel-poor homes — insulation, heating upgrades, repairs, and other measures that bring poorly-performing properties up to a better standard.

ECO4 is administered by Ofgem. It started in April 2022 and currently runs until 31 December 2026. The obligated suppliers include all the major household-name energy companies; smaller suppliers below a customer threshold are not required to participate but some take part voluntarily.

What makes ECO4 different from the Boiler Upgrade Scheme is its focus. BUS is open to most homeowners regardless of income and pays a fixed grant per measure. ECO4 is income-targeted, has no fixed grant per measure, and is delivered as a whole-house package rather than a single measure. That last point matters: ECO4 increasingly funds packages of insulation plus heating in one go, because that’s what makes a meaningful difference to a property’s EPC and to the household’s bills.

There are two main routes.

1. The main eligibility route — means-tested benefits

You qualify if your household receives one or more of the following benefits, and your home is rated D, E, F or G on its EPC:

• Pension Credit (Guarantee Credit and Savings Credit)
• Universal Credit
• Child Tax Credit
• Working Tax Credit
• Income Support
• Income-based Jobseeker’s Allowance
• Income-related Employment and Support Allowance
• Housing Benefit
• Child Benefit (income cap applies)

For owner-occupiers, the EPC band requirement is D to G. For social and private rented properties, eligibility is generally tighter (E to G), and landlords are required to contribute a share of the costs.

2. ECO4 Flex — through your council

If you don’t receive any of the qualifying benefits, you may still be eligible via ECO4 Flex (sometimes called LA Flex). This route lets local authorities extend eligibility to households who are on low incomes, in fuel poverty, or vulnerable to the effects of a cold home for health reasons.

Each council publishes its own Statement of Intent setting out the criteria it uses. In Leeds and West Yorkshire, the relevant councils are:

• Leeds City Council
• City of Bradford Metropolitan District Council
• Wakefield Council
• Kirklees Council
• Calderdale Council

Typical Flex criteria include a household income below a stated threshold (often around £31,000 nationally, sometimes adjusted locally), a household member with a long-term health condition exacerbated by cold (cardiovascular, respiratory, mobility-limiting), or being identified as in fuel poverty by an authorised referrer such as a GP or a charity. Specifics vary — check the latest Statement of Intent from your council before assuming you qualify or don’t.

The most commonly funded measures under ECO4 in West Yorkshire are:

• Loft insulation. Top-up to the current 270mm standard, or full installation where there’s none.
• Cavity wall insulation. Where the property has unfilled cavity walls in suitable condition.
• Solid wall insulation. External (EWI) or internal (IWI) wall insulation for the many stone- and brick-built Leeds and Bradford terraces with no cavity. This is the highest-impact measure for older West Yorkshire housing stock.
• Underfloor insulation. For homes with suspended timber floors.
• Heating upgrades. Including air source heat pumps for off-gas-grid homes and broken-heating replacement in qualifying cases.
• First-time central heating. For homes with no central heating system at all.
• Window upgrades. Limited to certain cases under ECO4’s “Innovation Measures” route.

ECO4 is delivered using PAS 2035 retrofit standards. That means a Retrofit Assessor inspects the property, a Retrofit Coordinator designs a package of measures, and PAS 2030 installers carry it out. The whole process is more thorough than a one-measure install — you should expect at least one survey visit before any work begins.

1. Check your eligibility. Look at the qualifying benefits list above. If you don’t qualify on benefits, check your local council’s ECO4 Flex Statement of Intent.
2. Contact an ECO4-capable installer or managing agent. ECO4 work is delivered through agents and installers signed up with the obligated suppliers. They handle eligibility checks, surveys and the application paperwork.
3. Retrofit assessment. Under PAS 2035, an assessor visits your property to identify what would make the biggest difference. This is paid for by the scheme, not by you.
4. Approval and installation. Once your case is approved by the energy supplier, installation is scheduled. Work is carried out by PAS 2030 installers.
5. Post-installation check. A Retrofit Coordinator signs off the work and the case is closed with the supplier.
