When Does Free Boiler Scheme End?

October 28, 2025

The boiler scheme is among the initiatives of the UK Government’s Energy Company Obligation (ECO4) program. It assists poor households in replacing outdated boilers with energy-efficient ones. 

The initiative is intended to reduce energy expenditure as well as mitigate carbon emissions within the nation. Most individuals are already wondering when the free boiler scheme is coming to an end so that they may not miss participating as it might be closed earlier than later.

What is the Boiler Replacement Scheme?

The boiler scheme is free for those who are unable to afford a new boiler themselves. It refunds you for a new A-rated energy-efficient boiler being installed. The funds are from the ECO4 scheme that started in 2022. This scheme is managed by major UK energy suppliers under government rules. Its prime aim is reducing fuel poverty and enabling houses that are in need of it to make better use of energy.

The program assists households that are on low incomes, poorly insulated, and with aging heating equipment. Homeowners as well as tenant households that receive some benefits are generally eligible to apply. The program ensures that all qualified homes are warmer, safer, and easier on heating bills. This reduces the burden on families that are struggling even more during winter. Hundreds of thousands of individuals in the United Kingdom already have access to this program.

When Does the Free Boiler Scheme End?

The ECO4 scheme helps people get free boiler grants, and it will end in March 2026. Homeowners still have some time to apply. But if you delay, you may have less of a chance because there is only so much money. Energy companies have annual targets, and when they reach their threshold, they may no longer accept new applications for some time.

Filing early increases your odds of approval prior to program completion. It is a time-consuming application because it involves inspection of property, ensuring you are eligible, and ordering installations. If you take too long, you can end up owing money if funds are exhausted or targets are met sooner than expected. Therefore, it is always best to act quickly in case you qualify for the grant.

Will There Be a New Scheme After 2026?

When ECO4 concludes in March 2026, the administration may embark on a new phase. Earlier programs such as ECO1, ECO2, and ECO3 had newer versions continue from them. Each version had updated rules to support more households and improve energy efficiency targets. There is also a chance that an ECO5 would displace ECO4.

But no official announcement is made so far regarding what would be continued after 2026. The government typically assesses whether the existing plan is performing well prior to commencing a new one. Their top priority is still achieving 2050 net zero emissions. Their energy grants would thus likely continue, but terms may differ. In order to be up to date, you can keep visiting the government’s energy saving schemes website regularly or consult registered ECO installers.

Why Is the Scheme Ending in 2026?

Why is its duration until 2026? Each government program possesses a specific time to attain certain aims. The ECO4 program was created to last from 2022 through 2026. This limitation ensures energy firms perform effectively to attain their objectives. These include optimizing the energy efficiency of buildings with low ratings and minimizing emission of carbon. Upon expiration of time, the government reviews the outcome and makes decisions on whether to continue with it or not.

The conclusion of ECO4 in 2026 is not a conclusion of aid to households. It is only that this phase is coming to an end. The review phase makes future plans easier through lessons on what was successful and what was unsuccessful. There may be greater focus on renewable heat solutions such as air source heat pumps or insulation grants in successive phases, for instance. So while the conclusion of ECO4 is certain, new opportunities may be available to homeowners down the road.

Who Should Apply Before It Ends?

The free boiler scheme is available to homeowners and private tenants with their landlord’s permission. But you are not eligible for everyone, and you will have to meet specific eligibility criteria.

Usually, you should apply if:

  • Your boiler is old and non-condensing (i.e. not working efficiently)
  • You receive any of the below government benefits: 
  •     Income Based – Jobseekers Allowance (JSA)
  •     Income Related – Employment and Support Allowance (ESA)
  •     Income Support Allowance (ISA)
  •     Working Tax Credit (WTC)
  •     Child tax credit (CTC)
  •     Universal Credit (UC)
  •     Pension Guarantee Credit
  •     Pension Savings Credit
  • Your home has a poor Energy Performance Certificate (EPC) rating, usually D, E, F, or G.
  • You live in England, Scotland, or Wales.

If you do not claim government benefits, you may still qualify under the ECO4 LA Flex option. It lets local authorities approve people on long-term illness with low incomes or high energy bills, even if they do not receive benefits.

How to Apply for the Free Boiler Scheme

Applying for the scheme is simple and free. You start by finding a registered ECO4 installer or provider. Most firms do have an online form that you can complete in a matter of minutes. You will need to give information on your home, your income, and what boiler you have installed. When you submit the form, the installer will then check whether you can receive the grant.

If you are approved, they will organize a no-charge home survey. The questionnaire helps to identify your home’s perfect heating solution. The installer then schedules a replacement date for you once you are approved. The installation would ordinarily take one to two days depending on your system. You do not have to pay anything if your grant covers the full cost.

What Happens If You Miss the Deadline?

If you miss the March 2026 deadline, you could have to wait until the subsequent program. There is no promise that the next phase will offer the same kind of support. Subsequent programs can be subject to different membership guidelines or reduced funding. This can imply that some homes will not be entitled to a free boiler replacement. It is preferable to act sooner rather than later to ensure that you do not lose your place.

Energy costs remain high, and replacing a boiler now could save you huge amounts of money annually. A new A-rated boiler is cheaper to run and warms more efficiently. If you don’t act in time, you could miss out on both the grant and the energy savings. So although 2026 seems like such a way-off date, it’s wise to apply now and reserve your place.

Conclusion

The boiler scheme for free assists low-income households in the United Kingdom. It is funded through the government’s ECO4 scheme that is set to finish in March 2026. Another scheme may follow, but that is not certain yet. Eligible applicants, especially those qualifying for the Boiler Replacement Scheme Over 60s, should apply as early as possible to avoid missing out on this opportunity. It can lower your bills with a new boiler now, keep you cosier, and enable your house to utilize energy better before it is too late.
