Free boiler grant if you get Universal Credit
If you receive Universal Credit and your home has a low energy rating, you may qualify for a free boiler replacement, loft or cavity wall insulation, or central heating fitted for the first time. The funding comes from the government's ECO4 scheme, which large energy suppliers must pay into.
The scheme runs until 31 December 2026, so there is a deadline. The check takes about two minutes and asks for your postcode first.
What the grant can cover
Boiler replacement if your current boiler is old and inefficient
First-time central heating if your home has never had a system
Loft insulation or cavity wall insulation where there is little or none
A free home survey and installation by certified engineers
Who qualifies on Universal Credit
You are likely to qualify if all of these apply:
- Someone in your household receives Universal Credit.
- Your home's Energy Performance Certificate (EPC) rating is D, E, F or G if you own it, or E, F or G if you rent from a private landlord. Don't know your rating? We check it for you.
- You own your home, or you rent privately and your landlord agrees to the work. We give you a short consent form for them.
There is no minimum amount of Universal Credit. It is the benefit itself that qualifies you, not how much you receive.
If you are a council or housing association tenant, your landlord may already be part of the scheme. Ask them first, or contact us and we will point you the right way.
What the grant can cover
ECO4 looks at the whole house, not just the boiler. Depending on your home, the survey may recommend:
- Boiler replacement if your current boiler is old and inefficient, usually a non-condensing model. See our boiler replacement page.
- First-time central heating if your home has never had a central heating system. See first-time central heating.
- Loft insulation or cavity wall insulation where your home has little or none. See loft insulation.
Homes rated D or E must be brought up to at least band C, and F or G homes to at least band D, so insulation is often fitted alongside heating work. That is a rule of the scheme, not an upsell.
Does it cost anything?
For most eligible households the boiler, the equipment and the installation are fully funded. The energy company decides how much it will fund for each home, and in some cases a small contribution may be asked for. We tell you clearly before any survey whether that would apply to you. There is nothing to repay.
How it works
- Check your eligibility online. Postcode, benefit, and a few details about your heating.
- We call you. An adviser confirms the details and books a free home survey at a time that suits you.
- Survey and installation. A qualified surveyor checks your home and EPC. If the funding is approved, certified installers fit the work. Most jobs take one to two days on site, and the whole process typically takes two to four weeks from enquiry to installation.
Common questions
- I've just moved on to Universal Credit. Do I qualify?
- Yes, as long as you receive it at the time you apply. There is no waiting period.
- Does applying affect my Universal Credit?
- No. The grant is not income and does not change your award.
- My boiler still works. Can I still apply?
- Possibly. ECO4 is about efficiency, not breakdowns. If your boiler is an older non-condensing model, it may still qualify. The survey decides.
- I rent from a private landlord. What do they have to do?
- Sign a consent form. The work is free to them too and improves their property's EPC, which most landlords welcome.
- When does this end?
- ECO4 closes on 31 December 2026. Applications need time for the survey and approval, so the sooner you check, the better. See is ECO4 still open? for the full picture.
