What questions we usually get about the free boiler replacement grant
Is this really free, or will I have to pay later?
No catch - if you qualify through the ECO4 scheme, the full cost of the new boiler and installation is covered. There’s no repayment, no hidden charges, and no subscription. Everything is handled through approved funding and Gas Safe installers.
What if my boiler still works - can I still get a new one?
Yes. Many older boilers still run but waste huge amounts of gas every day. If yours was installed before 2005 or isn’t condensing, you could still qualify. Replacing it now can cut bills by up to 30% and prevent costly breakdowns later.
Do I have to be on benefits to qualify?
Not always. While some routes depend on certain benefits, there are local-authority and income-based options that help many households who don’t receive benefits. We’ll check every available funding route for you - it takes under a minute.
Will the installation cause disruption?
Hardly at all. Most boiler swaps are completed in one day with minimal mess. Our certified installers protect flooring, remove the old unit, and test everything before leaving. You’ll have heat and hot water the same day.
Who actually pays for the new boiler?
The cost is covered by the ECO4 scheme, which is funded by major UK energy suppliers such as British Gas, EDF, E.ON, and others. They’re required by the government to help improve energy efficiency in UK homes. That means your upgrade is fully funded — you won’t pay a penny, and all work is carried out by approved Gas Safe engineers with proper certification.
