ECO4 ends 31 December 2026 — what replaces it in Bristol
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 Bristol
Bristol made history in November 2018 as the first UK city to declare a climate emergency — a move that has shaped every aspect of its housing and energy policy since. The city's One City Climate Strategy sets a 2030 carbon neutrality target, making it the most ambitious urban climate commitment in England. For Bristol's 198,600 households, this translates into an urgent need for domestic energy upgrades. The city's distinctive Pennant stone terraces — built from locally quarried dark sandstone in the Victorian era — present a particular challenge: their solid stone walls have among the worst thermal performance of any common UK wall type.Bristol was the first UK city to declare a climate emergency (November 2018) and hosts the Centre for Sustainable Energy, one of the UK's leading energy efficiency charities.
How ECO4 Works in Bristol
Bristol's City Leap Energy Partnership is one of the most innovative municipal energy programmes in Europe. A joint venture between the council and Ameresco, City Leap has attracted £500m of private investment in city-wide energy infrastructure including heat networks, solar farms, and battery storage. For individual homeowners, the Centre for Sustainable Energy (CSE) — Bristol's award-winning energy charity — delivers both general energy advice and LA Flex referrals. CSE's Bristol Energy Network connects over 50 community organisations, from Ambition Lawrence Weston's community wind turbine to Easton Energy Group's street-by-street retrofit programme.Available Grants in Bristol
Residents in the Bristol 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 Bristol, 3,890 ECO4 measures have been installed to date, with Loft insulation (32%) 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 Bristol
Bristol's LA Flex scheme is notably generous compared to many English local authorities. The income threshold of £33,000 — £2,000 higher than the standard — reflects the city's higher living costs. The council also accepts households where children receive free school meals and carers receiving Carer's Allowance, broadening eligibility beyond standard benefit-based criteria. For the city's extensive stock of stone-built terraces in Totterdown, Bedminster, and Easton, the primary ECO4 measure is internal wall insulation (IWI) — installed on the inside face of external walls, adding approximately 100mm of insulated plasterboard. While this slightly reduces room sizes, it cuts heat loss through solid walls by up to 65%.EPC Ratings in Bristol
