ECO4 ends 31 December 2026 — what replaces it in Sheffield
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 Sheffield
Sheffield — the UK's greenest city by proportion of green space — faces an energy efficiency challenge shaped by its dramatic topography. The city rises from 29 metres above sea level in the Don Valley to 548 metres at its highest point, and this altitude range creates measurable differences in heating demand. Properties in the exposed hilltop estates of Burngreave, Firth Park, and Netherthorpe face wind chill that can increase heat loss by 15-20% compared to sheltered valley-bottom homes. Sheffield's housing stock of 244,200 properties reflects this terrain: terraced streets climbing steep hillsides, council tower blocks on ridgelines, and suburban semis in the more sheltered western suburbs.Sheffield's Park Hill estate is the largest Grade II* listed building in Europe and is undergoing the UK's most ambitious listed building energy retrofit.
How ECO4 Works in Sheffield
Sheffield's approach to energy retrofit is defined by two landmark projects. The first is Park Hill — the Grade II* listed brutalist estate overlooking the city centre, which is undergoing the UK's most ambitious listed building retrofit. Urban Splash's phased renovation is demonstrating how even the most challenging 1960s system-built structures can achieve EPC B while retaining their architectural character. The second was the council's HUG2 programme, which secured £8.5m for off-gas properties in rural Sheffield; HUG2 has since been replaced by the Warm Homes: Local Grant. The city's Peak District fringe — Stocksbridge, Oughtibridge, Bradfield — includes thousands of stone-built properties heated by oil or LPG, making them priority candidates for heat pump installation.Available Grants in Sheffield
Residents in the Sheffield City 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 Sheffield, 4,820 ECO4 measures have been installed to date, with Cavity wall insulation (33%) 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 Sheffield
For Sheffield homeowners seeking ECO4 funding, the council's self-referral system is notably accessible. Unlike many authorities that require GP or social services referrals, Sheffield accepts online applications directly through its website. The council's energy team then triages applications based on EPC rating, household vulnerability, and neighbourhood priority. Properties in the 30% most deprived areas (measured by the Index of Multiple Deprivation) are fast-tracked, with typical waiting times of 4-6 weeks from application to survey. Sheffield's 40 TrustMark-registered installers provide competitive quotes, and the council's quality monitoring team inspects 10% of all completed installations — double the national minimum.EPC Ratings in Sheffield
