ECO4 ends 31 December 2026 — what replaces it in Wolverhampton
ECO4 has been extended once, to 31 December 2026, so suppliers can finish existing targets and fix faulty installs only. There are no new targets, no carry-over and no ECO5. The Great British Insulation Scheme closed to new applications on 31 March 2026.
In England the replacement for low-income households is the Warm Homes: Local Grant — a £500m scheme delivered by councils and their appointed installers from April 2025 to March 2028, for privately owned and privately rented homes rated EPC D to G where the council is taking part. Owner-occupiers can have insulation, heating and solar fully funded. Tenants pay nothing; a landlord gets one home fully funded, then contributes 50% from the second.
One of these three routes must apply:
- Household income of £36,000 a year or less before tax; or
- Someone in the home gets one of: Universal Credit, Pension Credit, Housing Benefit, Income Support, income-based Jobseeker's Allowance or income-related Employment and Support Allowance; or
- The home is in a postcode the government lists as among the most deprived (IMD deciles 1–2).
On top of one of those routes, the home must be rated EPC D to G and you must be an owner-occupier or a private tenant (with your landlord's consent — rented homes rated F or G need a registered MEES exemption). Social housing is not eligible.
Over 97% of eligible councils in England (271) are funded to deliver it, but funding and timing vary by area, and your council will usually contact you within 10 working days of a referral.

Not eligible, or paying yourself? The Boiler Upgrade Scheme takes £7,500 off an air source or ground source heat pump for most homeowners replacing fossil-fuel heating in England and Wales, with no income test and no EPC needed since 28 April 2026 (£9,000 for an air or ground source heat pump in oil- or LPG-heated homes with no mains gas connection, until 31 March 2027). The £150 Warm Home Discount comes off your electricity bill again this winter, and if you are buying solar, 0% VAT applies until 31 March 2027 — get a solar quote from one MCS-certified installer. Need a like-for-like gas boiler? The Warm Homes: Local Grant cannot fund new gas boilers, so outside ECO4 you would pay an installer’s quote — ask your council about any emergency heating fund.
Energy Grants & Fuel Poverty in Wolverhampton
Wolverhampton — the 4th most fuel-poor local authority in England — sits at the heart of the Black Country, a post-industrial landscape where the legacy of iron, steel, and lock-making shaped both the economy and the housing stock. The city's 109,200 households include a substantial proportion of inter-war semi-detached properties built between 1930 and 1945, when the Black Country's industrial output was at its peak. These homes typically have unfilled cavity walls, uninsulated lofts, and original single-glazed steel-framed windows — a combination that results in annual heating costs 40-60% higher than a modern equivalent.Wolverhampton's Black Country Consortium LA Flex partnership is England's most integrated cross-boundary ECO4 delivery programme, covering four boroughs seamlessly.
How ECO4 Works in Wolverhampton
The Black Country Consortium — a partnership between Wolverhampton, Walsall, Sandwell, and Dudley councils — has created the most integrated cross-boundary ECO4 delivery programme in England. Rather than four separate council schemes with different eligibility criteria and installer panels, the Consortium operates a single referral system, a shared quality assurance framework, and joint installer procurement. For Wolverhampton residents, this means access to a wider pool of TrustMark-registered installers and shorter waiting times. The Consortium's bulk purchasing power has reduced cavity wall insulation costs by 18% compared to individual authority procurement.Available Grants in Wolverhampton
Residents in the City of Wolverhampton Council area can access several government-funded energy efficiency schemes:
ECO4 Scheme
The Energy Company Obligation (ECO4) can fully fund energy improvements for households receiving qualifying benefits (installers sometimes ask for a top-up). Measures include loft insulation, cavity wall insulation, solid wall insulation, boiler replacements, solar panels, and air source heat pumps. Your property needs an EPC rating of D, E, F, or G. In Wolverhampton, 3,450 ECO4 measures have been installed to date, with Cavity wall insulation (38%) being the most common.
Great British Insulation Scheme (GBIS)
The GBIS closed to new applications on 31 March 2026 — if you don't claim benefits, check LA Flex and the Warm Homes: Local Grant instead. Until it closed, GBIS provided free or heavily subsidised insulation to properties in council tax bands A-D (England). No means test is required — eligibility is based on your property, not your income.
Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme offers £7,500 towards an air source or ground source heat pump (£5,000 for a biomass boiler). Available to homeowners in England and Wales replacing fossil-fuel heating, with no income test (a valid EPC has not been required since 28 April 2026).
Warm Home Discount
A £150 discount on your electricity bill each winter. Most eligible households receive this automatically.
Local Energy Efficiency in Wolverhampton
Heath Town, Low Hill, and Bushbury form Wolverhampton's fuel poverty triangle — three adjacent wards where fuel poverty rates exceed 25%. These areas contain some of the city's oldest housing, including pre-1919 terraces around Wolverhampton's former industrial core and 1950s council estates built to rehouse families from slum clearance programmes. The council's targeted approach concentrates ECO4 resources in these wards, with door-to-door canvassing teams visiting every property to assess eligibility. This focused strategy has resulted in a 45% ECO4 uptake rate in the target wards — among the highest in the country — compared to the national average of around 12%.EPC Ratings in Wolverhampton
