ECO4 & ECO6 Scheme Updates 2025: New Grants and Eligibility in England
The year 2025 marks an exciting phase for UK households, with both ECO4 and the pilot ECO6 scheme driving stronger support for energy efficiency upgrades. These updates ensure more families across London, Birmingham, Manchester, and Leeds can benefit from warmer, greener, and more affordable homes.
Here’s what’s new compared with earlier phases:
Focused Support for Low-Income Households
ECO4 continues to prioritise families struggling with fuel poverty. At Reliant Energy Solutions, we work with local councils in London, Manchester City Council, and Birmingham City Council to ensure vulnerable groups can access free heating and insulation measures quickly.
Expanded Eligibility for Private Renters & Housing Associations
More tenants, including those in social housing through local housing associations, can now apply for grants — provided the landlord consents to the upgrades. Reliant Energy Solutions partners with housing providers across Greater London and the Midlands to streamline this process.
Increased Funding for Heat Pumps & Hybrid Systems
With the UK pushing for net zero, ECO4 and ECO6 now offer higher funding for air source heat pumps and hybrid heating systems. Families in urban areas like Leeds and rural communities across Yorkshire and Lancashire are seeing big savings on bills — often up to 50%.
Better Support for Homes Without Gas Supply
Properties in off-gas areas such as Cornwall, Cumbria, and rural Kent can now benefit from renewable solutions like heat pumps and solar PV, fully installed by Reliant Energy Solutions’ accredited teams.
Wider Range of Energy-Saving Upgrades
Beyond boilers, grants now cover solar panels, smart heating controls, cavity wall insulation, and loft insulation. Our teams in Sheffield, Liverpool, and Newcastle are helping households future-proof their homes and boost EPC ratings.
With energy prices remaining high across England, the ECO4 and ECO6 schemes delivered locally by Reliant Energy Solutions in partnership with councils and housing associations are a lifeline for families looking to save money while contributing to a sustainable future.

Frequently Asked Questions: Deep-Dive Expert Answers
What is the best heating system for ECO4 applicants with electric-only heating?
The most effective option is an air source heat pump, which offers superior efficiency and can cut bills by up to 50%. In some cases, high-retention storage heaters or hybrid systems may be approved, but heat pumps remain the gold standard.
Can I get a grant for an electric boiler under ECO4?
Electric boilers are rarely funded unless a heat pump isn’t technically feasible. The ECO4 scheme prioritizes low-carbon technologies, meaning air source heat pumps are usually the first choice.
What are the eligibility requirements for ECO4 if I have no gas supply?
You’ll need an electric-only system, a low EPC rating, and to meet the scheme’s income or benefits criteria. Private tenants must provide landlord permission, while all installations are carried out by accredited professionals through providers like Reliant Energy Solutions.
How much could I save by switching to a heat pump?
Most households switching from direct electric heating to a heat pump save 30–50% on bills, amounting to £500–£1,000 per year.
Can I combine ECO4 with other grants?
Yes — in many cases, Reliant Energy Solutions helps applicants combine ECO4 with ECO6 pilots and local council grants, maximizing the funding available for your home.
