Boiler Grants by Situation: Owners, Renters and Benefits
Boiler grants can pay for a new gas boiler, a heat pump or insulation, and the right one depends on your income, your home and where you live. ECO4 funds gas boilers for qualifying homes, with work finished by 31 December 2026. The Boiler Upgrade Scheme gives £7,500 off an air or ground source heat pump in England and Wales. The Warm Homes: Local Grant helps lower-income homes in England. One eligibility check shows which fits you.
FreeBoilerUpgrade.uk is the installer behind this site, run by Reliant Energy Solutions Ltd from Middleton, Manchester.
Which boiler grant fits your home?
The right boiler grant follows from the work your home needs. Use the table to match the job to the scheme that can pay for it.
| What you need | Grant that can pay | Who it usually suits |
|---|---|---|
| A new gas boiler | ECO4 (the free boiler scheme) | Homes where someone gets a qualifying benefit, or the council refers you |
| A heat pump instead of oil, gas or electric heating | Boiler Upgrade Scheme | Owners in England and Wales |
| Insulation, a heat pump or solar on a lower income | Warm Homes: Local Grant | Privately owned homes in England, rated EPC D to G |
| Heating in a home with no central heating system | ECO4 first time central heating | Qualifying homes that have never had radiators fed by a boiler |
| Help without any benefit | ECO4 through your council (LA Flex) | Lower-income or health-related cases the council accepts |
Every scheme, side by side with its closing date and whether it pays for a gas boiler, is on our boiler replacement scheme comparison.
Free boiler scheme: how does ECO4 pay for a new boiler?
ECO4, the Energy Company Obligation, is the scheme behind most free boiler grants, and it is how a free boiler upgrade usually happens. Energy suppliers fund a new boiler in a qualifying home and Ofgem runs it, so no money is paid to you.
It usually suits an owner-occupied home rated D to G, where someone gets a benefit such as Universal Credit or Pension Credit and the boiler is old, non-condensing or broken beyond repair. Private renters cannot have an existing boiler swapped. The full tests are on our ECO4 eligibility page.
ECO4 work only counts if it is finished by 31 December 2026, so the fitting date matters more than the day you ask. Our ECO4 extension guide explains what that means for a job already started.
Check If You Qualify
Answer a few questions about your home and situation. This is a free, no-obligation check, not a guarantee that every home gets a grant.
Boiler Upgrade Scheme: How Much It Pays for a Heat Pump
The Boiler Upgrade Scheme is the government's heating grant: £7,500 towards an air source or ground source heat pump, or £5,000 towards a biomass boiler. Until March 2027, homes heated by oil or LPG with no mains gas connection can get an extra £1,500, so up to £9,000.
You need to own the property in England or Wales, and the new system must replace a fossil fuel heating system (oil, gas, electric or LPG). Under the scheme, the grant comes off the installer's quote, so you never handle the money.
It does not pay for a new gas boiler. Our heat pump grant page explains what the grant covers and what is usually left to pay.

Book Free SurveyWarm Homes grants in England and loans across the UK
Warm home grants in England come mainly through the Warm Homes: Local Grant, which councils run for privately owned homes rated D to G. It pays for insulation, heat pumps, solar panels and smart controls, but not gas boilers. Income is usually £36,000 a year or less, or you live in a qualifying postcode area.
We help you apply, from the form to your documents. Each council's position is on our Warm Homes: Local Grant page.
Both sit under the government's Warm Homes Plan, which set out £15 billion to upgrade up to 5 million homes by 2030. The Warm Homes Plan now stands at just under £15 billion, including an additional £1.5 billion announced at the Budget. No- and low-interest Warm Homes loans are available to households across the UK. Our Warm Homes Plan guide tracks each change.
Help that fits your situation
The right heating grant often depends on your benefits, age or health more than on the boiler. These pages each cover one situation in full.
Pensioners:
Pension Credit counts for ECO4, and the State Pension alone may still work through the council. Read about boiler grants for pensioners.
Disabled, or on PIP or Attendance Allowance:
these do not qualify by themselves, but an award letter can help through the council. See boiler grants for disabled people.
On Universal Credit, including if you work:
our free boiler on Universal Credit page covers claimants.
Not on any benefit:
the council route and the heat pump grant are both open to you. Start with can I get a boiler grant if I'm not on benefits.
In Scotland:
ECO4 runs on the same dates, and Scotland has its own help too. Compare them on our boiler grants Scotland page.

How the Process Works, Step by Step
Getting any boiler grant with us takes four steps, and nothing is fitted before the job is approved.
- 1
Eligibility check:
by phone, WhatsApp or our online checker.
- 2
Survey:
a visit to your home.
- 3
Approval:
the funding for the job is approved before any work starts.
- 4
Installation:
fitting typically takes 1 to 2 days on site once approved.
How long the whole process takes depends on your paperwork and the survey.
Is a boiler grant really free?
ECO4 is funded by energy suppliers, and Ofgem says a household may be asked to contribute in some cases. With us, the energy supplier pays for the approved ECO4 work, and any extras are agreed in writing first. The Boiler Upgrade Scheme is a set amount off the price.
Under the Warm Homes: Local Grant, your council organises and pays for the agreed work, and you will not need to pay for it. Landlords may need to pay for some improvements. With the Boiler Upgrade Scheme, you pay whatever the heat pump quote is above the grant, so ask for the full figure in writing before you agree.
Be wary of anyone who asks for a registration fee or your bank details to release a grant. Our guide to spotting a fake free boiler offer lists the warning signs.

Where we work
We survey and fit across England and Scotland from our office in Middleton. Our nearest towns are Manchester, Salford, Stockport and Oldham.
Local detail is on our pages for boiler grants in Manchester and Stockport, and everywhere else we cover is on our areas we cover page. We do not work in Northern Ireland, where the Boiler Replacement Scheme is now closed. The Boiler Upgrade Scheme covers England and Wales, but we survey and fit only in England and Scotland.
What Changes After ECO4 Closes
When ECO4 closes, free gas boilers through energy suppliers stop, because the government has decided to bring supplier obligations to a close. Heat pump grants, insulation and Warm Homes support carry on after that.
That is why this site covers every route, not just the free boiler scheme. If ECO4 runs out of time for your home, the Boiler Upgrade Scheme or Warm Homes help may still fit, and we can look at both with you.

Questions People Ask
How do you get a boiler grant?
Find out which grant fits your home first, because each has its own rules. With us, that starts with one eligibility check, then a free survey and approval before any work.
Is there a government boiler grant?
Yes. The Boiler Upgrade Scheme is the government boiler grant, paid towards a heat pump or biomass boiler. ECO4 is set by government but paid for by energy suppliers, and it is the route that can cover a gas boiler.
What is a new boiler grant?
A new boiler grant, or boiler replacement grant, usually means ECO4 funding for a qualifying home. It covers a new A-rated condensing boiler in place of an old or broken one, and any extras are agreed in writing first.
Is it worth replacing a 20-year-old boiler?
An old boiler is often non-condensing. ECO4 can upgrade a non-condensing boiler to an efficient heating system if the household qualifies. Our article on government help for a boiler over 15 years old goes further.
How much should a boiler replacement cost?
Private replacement costs depend on the home, so we confirm the price in writing after a free survey. Homes that qualify for ECO4 are covered in the section on whether grants are really free.
