ECO Flex Grant
Flexible support for warmer, more efficient homes
Check my eligibilityThe ECO Flex Grant is part of the UK government’s Energy Company Obligation scheme—but with added flexibility. It allows local authorities to refer households for free energy upgrades, even if they don’t receive benefits.
That means more people can now get fully funded home improvements like insulation, a new boiler, solar panels or an air source heat pump.
Warmify works directly with councils and energy providers to make the whole process simple, clear, and stress-free.

What is the ECO Flex Grant?
The ECO Flex Grant is part of the broader ECO4 scheme, but it gives local authorities the power to widen who can get help.
Instead of needing to receive benefits, you might qualify based on:
- Low income
- High energy bills
- Health conditions made worse by the cold
- Living in a hard-to-heat home
It’s ideal for people who fall between the cracks—struggling with energy costs, but not eligible under traditional rules.
Warmify works with your local council to get you the help you need.
Who is eligible for the ECO Flex Grant?
You may qualify for the ECO Flex Grant if:
- You live in England or Wales
- You own your home or rent privately (with landlord permission)
- Your home has an EPC rating of D, E, F or G
- And your household fits one of these flexible routes:
- Your gross annual income is under £31,000
- You have a health condition made worse by living in a cold home
- Your home is energy-inefficient and your income after housing costs is under £20,000
- You’ve been referred by a professional (like a GP or support worker) under your council’s own Flex policy
Every local authority sets their own flexible eligibility rules. Warmify will help guide you through your council’s criteria and check your eligibility for free.
