UK free boiler scheme guidance
Free Boiler Scheme UK 2026: Who Qualifies for ECO4 & LA Flex?
Looking for the free boiler scheme in the UK? In 2026 that usually means help through ECO4 or LA Flex — routes that can fully fund a boiler replacement for eligible households — not a single “apply once, everyone qualifies” button.
Free Boiler Upgrade helps you check whether those pathways may fit your home, with clear next steps and no invented grant amounts.
Yes — for eligible homes. The UK free boiler scheme people search for is usually the Energy Company Obligation (ECO4) or council LA Flex pathway: a fully funded or free boiler replacement when you meet the rules — not a national voucher for every address. Check ECO4 eligibility first, or LA Flex if you are not on benefits. ECO4 measures must be installed by 31 December 2026, and availability varies by area.

Check if you may qualify
Answer a few questions about your home and situation. This is a free, no-obligation check for ECO4 or LA Flex pathways — not a guarantee that every home gets a free boiler.
ECO4 ownership rules
Who can qualify?
Free boiler grants are for private tenants and homeowners — not social housing.
Can qualify
Eligible ownership types
Homeowners
You own your home (freehold or leasehold) and live there as your main residence.
Private tenants
You rent privately — landlord permission is needed before installation.
Cannot qualify
Not covered on this route
Social housing tenants
Council or housing association homes usually go through the landlord, not this scheme route.
Business / commercial only
Shops, offices and non-domestic buildings are not covered by domestic ECO4.
You still need a qualifying benefit or LA Flex route, plus EPC band D–G. Use the form to check in under a minute.

What is the free boiler scheme in the UK?
When people say free boiler scheme, they usually mean government-backed energy-efficiency programmes where obligated energy suppliers (or approved installers working under those rules) fund heating upgrades for qualifying homes.
- ECO4 is the main national obligation route many households use for a free or fully funded boiler when benefits, income, or housing criteria are met.
- LA Flex lets councils nominate people who may not claim benefits but still meet local fuel-poverty or vulnerability criteria.
- Related policy context sits under the wider Warm Homes plan — that page covers the broader framework; this homepage is for free boiler scheme / ECO4-style boiler intent.
There is no universal entitlement. Funding and eligibility both have to line up. Homes with old, inefficient boilers often pay more to heat — for eligible households, an ECO4 or LA Flex upgrade is about a safer, warmer system under scheme rules, not a marketing voucher.
Your EPC rates the home from A to G. ECO4 often uses it as one factor; less efficient homes are more likely to need heating upgrades. If you do not know your rating, it can be checked during assessment.
Free boiler scheme vs Boiler Upgrade Scheme (BUS)
These are easy to mix up in search results:
| Free boiler scheme (ECO4 / LA Flex) | Boiler Upgrade Scheme (BUS) | |
|---|---|---|
| What it is | Obligation / Flex help that can fund a boiler replacement for eligible homes | Official gov.uk grant path aimed at heat pumps (and related low-carbon heating) |
| Who typically helps | Suppliers / installers under ECO rules; councils via LA Flex | Government BUS process on GOV.UK |
| This site | Eligibility checks and guidance for ECO4 / LA Flex boiler pathways | We do not administer BUS — follow GOV.UK if that is what you need |
If you landed here from a BUS / heat-pump grant search, use the official GOV.UK Boiler Upgrade Scheme pages. If you want a free or fully funded boiler replacement under ECO4 or LA Flex, stay here and start with ECO4 eligibility.
Who is entitled to a free boiler in 2026?
In most cases, you need to be on a qualifying benefit and live in a home with a low energy rating. Owners, private renters (with the landlord's written permission) and some social tenants can all be eligible, but the rules differ slightly for each.
Benefits that can qualify you
| Benefit | Who usually claims it |
|---|---|
| Universal Credit | The most common route for working-age households |
| Pension Credit (Guarantee Credit) | Older households on a low income |
| Pension Credit (Savings Credit) | Older households with small savings and income |
| Income Support | Low-income households not expected to look for work |
| Income-based Jobseeker's Allowance | Households looking for work on a low income |
| Income-related Employment and Support Allowance | Households unable to work because of illness or disability |
| Child Benefit | Income limits apply |
| Housing Benefit | Helps with rent for people on a low income |
List as published on GOV.UK, Energy Company Obligation. Scheme rules can change, so the eligibility check is the final word.
What energy rating does the home need?
- Homeowners: an EPC rating of D, E, F or G.
- Private renters: E, F or G, and you must have the owner's permission for the work.
- Social tenants: E, F or G, usually arranged through the housing association or council.
Don't know your rating? Look it up with our EPC checker.
Do PIP or Attendance Allowance qualify me?
Disability benefits such as PIP, DLA and Attendance Allowance are not on the main GOV.UK list above. That does not close the door. A disability or long-term health condition can still count through your council's LA Flex route, and each council sets its own criteria. Our guides for disabled households and pensioners go into the detail.
When you might not qualify
- Your home is already rated A, B or C, and your council has no other qualifying route.
- You are a tenant and your landlord will not give written permission.
- You want a heat pump. That sits under a separate government grant, the Boiler Upgrade Scheme.
- Funding in your area has run out. Availability can differ by installer and by council.
Bottom line: If you receive a qualifying benefit and your home is rated D–G (E–G if you rent), you are a strong candidate. If you do not receive one, check your council's LA Flex rules. Either way, approval depends on a survey and available funding.
Is there a government free boiler scheme, and could I get it?
Not as one national voucher. The government sets ECO4, energy suppliers pay for it, and councils can add households through LA Flex. It covers England, Scotland and Wales; Northern Ireland has its own separate schemes. Here is a quick checklist to see where you stand.
- You own your home, or you rent privately and your landlord has agreed in writing.
- Your home has an EPC rating of D–G (owners) or E–G (renters), or your council confirms a different route.
- Someone in the household gets a qualifying benefit, or your council runs an LA Flex route that fits your income or health.
- Your current heating is old, inefficient or broken. A non-condensing gas boiler fitted before about 2005 is a typical example.
- Your area still has funding and installer capacity (this varies, and we tell you straight if it doesn’t).
Should I wait, or replace my boiler now?
If your boiler still works, a free check costs you nothing, so run it first. If it is leaking, failing or unsafe, don't go without heat or hot water while you wait: have it repaired or replaced by a Gas Safe engineer. Funded help is never guaranteed, and a survey and approval take time.
Bottom line: Meeting most of these points is a good sign, not a promise. Only a survey and your supplier or council can confirm approval.
Old heating system vs a new ECO4 boiler
Toggle before and after to see the kind of upgrade eligible households can receive when funding and survey outcomes line up. Individual results vary — this is an example of the work, not a promise of savings or timelines.

Am I eligible for a free boiler?
At a high level, successful ECO4-style applications often involve one or more of:
- Qualifying benefits or low income
- A poorer EPC (often mid-to-low bands — exact thresholds depend on tenure and package)
- Private ownership or private rental (social housing routes differ)
Exact checks belong on the eligibility pillar — not guessed from social media “everyone qualifies” posts.
Check ECO4 eligibilityNo benefits? LA Flex may still help
If you are searching change boiler for free or how to get a free boiler but you are not on benefits, your council's LA Flex statement of intent may still open a route via income caps, health vulnerability, or similar local criteria.
LA Flex schemeHow the free boiler scheme works
- Check eligibility — Start with ECO4 or LA Flex.
- Survey — Eligible homes usually get a survey before measures are agreed.
- Install — Agreed heating work is installed under the scheme rules when funding is available.
How long a free boiler replacement takes varies by survey outcome, installer capacity, and scheme funding. We do not publish a fixed day-count here because there is no single verified SLA that fits every UK home.

Is there a British Gas, Octopus or E.ON free boiler scheme?
Not as a separate scheme you join by being a customer. The big suppliers, including British Gas, Octopus Energy, E.ON Next, EDF, OVO and ScottishPower, are legally required to fund ECO4 work. That is the money behind most funded boilers, whichever company you pay for your energy.
Under the ECO4 rules, what matters is your household and your home: your benefits or income, your property's energy rating, and your tenure. Some suppliers also run their own offers or grant pages that change from year to year, so check the supplier's own site, for example British Gas heating grants, for anything current.
Be cautious of adverts, texts or calls that use a supplier's name to promise a free boiler to everyone. If it sounds universal, it is not how the scheme works. See how ECO4 compares with other schemes.
Bottom line: There is no “join your supplier” shortcut. Eligibility is about you and your home, and any supplier can sit behind an approved ECO4 install.
Is the free boiler scheme still open in 2026?
Possibly, but it is not guaranteed. 31 December 2026 is the date by which ECO4 measures must be installed, so eligible households can still be assessed. There is no successor supplier obligation, and availability varies by supplier, installer and council, so some areas may already be closed to new applications. Installer diaries and funding also tighten as the end date nears, which is why checking sooner usually beats waiting.
What follows ECO4 is the government's Warm Homes Plan. It works differently, so don't assume today's rules will carry over. If your boiler is old, unreliable or inefficient, there is no benefit in leaving the check until the final weeks of the year.
Bottom line:
The free boiler scheme is open until the end of 2026. Check now, then you know where you stand whatever happens next.
Can a health condition or a cold home help me qualify?
Not by itself. A diagnosis does not automatically unlock a funded boiler. Where it can matter is the council-led LA Flex route, because many councils recognise that a cold, damp home is dangerous for people living with heart or lung conditions, reduced mobility, or a weakened immune system.
- Each council publishes its own criteria, so what counts in one area may not in the next.
- Some councils ask for supporting evidence, such as a letter from a GP or other professional.
- Income, fuel poverty and the home's energy rating are usually weighed alongside health.
What boiler will I get, and will they just repair mine?
The scheme is built around replacing an inefficient or failed boiler with a modern condensing model, not patching up the old one. A surveyor visits first, checks your existing system and pipework, and confirms what suits the property before any work is agreed.
Your EPC rating also matters. Homes in bands D to G are the usual target because they lose the most heat and money. Not sure of yours? Look it up with the EPC checker, or compare options on our boiler types and boiler comparison pages.
If your boiler has already stopped working, you can still check eligibility. Just remember the process involves a survey and approval, so it is not an emergency repair service. Sort a safe temporary option for heat and hot water while it is arranged.
Is the free boiler scheme genuine? How to spot a scam
ECO4 is a real government obligation overseen by Ofgem, and it is also a favourite of cold callers. A few habits keep you safe:
- Never pay a “registration” or “admin” fee up front for a funded boiler.
- Be wary of unsolicited calls, texts or door knocks claiming your home has been “pre-approved”.
- Confirm any installer is on the Gas Safe Register and registered with TrustMark.
- Take time to read anything before signing, and ask for any extra costs in writing.

Check ECO4 eligibilityIs the boiler really free, and how long does it take?
If your home is approved, the boiler replacement itself is funded and there is nothing to pay back. ECO4 is not a loan. Ask for any other costs in writing before you agree to work.
- Possible extras: some homes need a new gas connection, which is arranged with the local gas network operator and is not part of the funding. Our city guides name the operator for each area.
- Timing: a survey comes first, then installation once funding and an installer slot are confirmed. We do not quote a fixed number of days because it genuinely varies from home to home.
- Broken boiler: the scheme is not an emergency repair service, so arrange safe temporary heating and hot water while your application is processed.
Bottom line: Approved homes pay nothing for the boiler itself. The only costs to watch for are extras outside the funding, so get every figure in writing.

Is the free boiler scheme still open in 2026?
Is the free boiler scheme still open in 2026?
Possibly. Ofgem says ECO4 measures can be installed until 31 December 2026, but some suppliers and installers stopped taking new applications earlier, so availability depends on where you live and who you ask. The government's Warm Homes Plan is the longer-term successor, and its rules differ. Checking early is the safest way to avoid a rushed finish.
Can a health condition get me a free boiler?
Can a health condition get me a free boiler?
A health condition on its own is not an automatic ticket. Some councils, however, use LA Flex to help households where cold homes make conditions such as heart or lung disease, limited mobility or a weakened immune system worse. Each council sets its own criteria, so the check looks at your local route.
Is there a government free boiler scheme?
Is there a government free boiler scheme?
Not a single government voucher. ECO4 is a government-set obligation that energy suppliers must fund, and LA Flex lets councils refer extra households. Both give a free or fully funded boiler only to homes that meet the rules. The separate Boiler Upgrade Scheme gives £7,500 towards a heat pump, not a gas boiler.
Should I wait for a free boiler or replace mine now?
Should I wait for a free boiler or replace mine now?
If your boiler works, checking eligibility now costs nothing. If it is failing or unsafe, don't go without heating or hot water while you wait: get it repaired or replaced by a Gas Safe engineer. Funded help is never guaranteed, and it can take weeks to arrange.
Can I get a free boiler from British Gas or my energy supplier?
Can I get a free boiler from British Gas or my energy supplier?
Large suppliers fund ECO4 work, but you do not normally apply through your own supplier's account, and being a customer does not improve your chances. Funding is allocated by the scheme's rules and the installers working under them. Be cautious of anyone who says a specific supplier is giving boilers away.
Is a funded boiler replacement really free?
Is a funded boiler replacement really free?
When a home qualifies and the measure is approved, the boiler replacement itself is funded, with nothing to repay. Some jobs can involve extras that sit outside the funding, such as a gas supply connection, so ask for any costs in writing before agreeing to work.
Can tenants and landlords apply?
Can tenants and landlords apply?
Private tenants can often apply, but the landlord has to give written permission because the boiler belongs to the property. Private landlords can also apply for rented homes in some cases. Social housing tenants usually go through their housing association or council instead.
My boiler has broken down. Can I still apply?
My boiler has broken down. Can I still apply?
Yes, you can still check eligibility, and a broken or very inefficient boiler is a common reason people apply. The scheme is not an emergency repair service, though: surveys and approval take time, so arrange a safe temporary heating option if you are without hot water or warmth.
Will my old boiler be repaired or replaced, and what type will I get?
Will my old boiler be repaired or replaced, and what type will I get?
The scheme funds replacement with a modern, efficient condensing boiler where a survey shows it is suitable, rather than repairs to an old one. The right type depends on your home and existing system, and the surveyor confirms it before any work starts.
Is the free boiler scheme genuine, and how do I avoid scams?
Is the free boiler scheme genuine, and how do I avoid scams?
ECO4 is a real, Ofgem-administered government obligation. Scams tend to involve cold calls, pressure to sign on the spot, or requests for upfront payment. Check that any installer is Gas Safe registered and TrustMark registered, and never hand over bank details to someone who contacted you unprompted.
Free boiler scheme jargon, in plain English
- ECO4
- ECO4 is the government scheme that requires large energy suppliers to fund heating and insulation upgrades for low-income and vulnerable households. It applies to measures installed between April 2022 and 31 December 2026.
- LA Flex
- LA Flex (Local Authority Flexible Eligibility) is the route that lets a council refer households who do not receive a qualifying benefit but still meet its published low-income or vulnerability criteria.
- EPC
- An EPC is an official A to G rating of how energy efficient a property is. Lower-rated homes, usually D to G, are the ones most likely to qualify for ECO4 help.
- Ofgem
- Ofgem is the energy regulator for Great Britain. It administers ECO4 and publishes the delivery guidance that suppliers and installers follow.
- Boiler Upgrade Scheme
- The Boiler Upgrade Scheme (BUS) is a separate GOV.UK grant towards installing a heat pump. It is not the same as a free boiler replacement under ECO4.
- Warm Homes Plan
- The Warm Homes Plan is the government's long-term home upgrade programme and the planned successor to ECO4, funded directly by government rather than through energy bills.
- Gas Safe
- Gas Safe is the official register of engineers legally allowed to work on gas appliances in the UK. Anyone fitting your boiler should be on it, and you can check them on the Gas Safe Register.
The free boiler scheme in a nutshell
The UK free boiler scheme usually means ECO4 or council LA Flex: funded boiler replacement for eligible homes, based on benefits or income and a low EPC rating, with measures to be installed by 31 December 2026. Free Boiler Upgrade UK is an independent eligibility guidance service registered at Companies House and based in Manchester. It helps households across England, Scotland and Wales check which route may apply, with 07342 267215 for questions. Nothing here is a guarantee of approval; every application depends on eligibility, a survey and available funding.
