The Warm Homes Plan is the UK government’s £15 billion programme, run by the Department for Energy Security and Net Zero (DESNZ), to upgrade up to five million homes by 2030. Low-income households in England can get free upgrades through the Warm Homes: Local Grant. Other homeowners can use heat pump grants or loans.

Where things stand on 7 October 2026
Confirmed
  • ECO4 ends on 31 December 2026 and there will be no ECO5.
  • The Great British Insulation Scheme ended on 31 March 2026.
  • The Warm Homes: Local Grant is available now in England where your council has funding. It runs to 31 March 2028.
Not yet announced
  • The rules and start date of the single low-income scheme the government intends from 2027/28.
  • When the new Warm Homes Agency will start work.

What the Warm Homes Plan funds

The plan commits about £15 billion of public investment over this Parliament, with spending profiled to 2029/30. It pays for grants for low-income households, heat pump grants, low-interest loans and heat networks. It is a funding programme, not one application form, so you apply to the individual schemes it pays for.

StrandPlanned fundingWho it is forWhere it runs
Low-income grantsAbout £4.4 billion in grants, plus £0.6 billion from the Warm Homes Fund (about £5 billion to 2030)Low-income and fuel-poor householdsWarm Homes: Local Grant (private homes in England) and the Warm Homes: Social Housing Fund (through social landlords)
Boiler Upgrade SchemeAbout £2.7 billion to 2030Households replacing heating with a heat pump or biomass boilerEngland and Wales
Consumer loansAn initial £2 billion of government supportOwner-occupiers and private landlords, with no income thresholdWarm Homes Loan Scheme, through participating lenders, UK-wide
Heat networksAbout £1.1 billionHomes that connect to district heatingDelivered through heat network projects

Figures are the government’s planned allocations in Chapter 3 of the Warm Homes Plan (DESNZ, 2026). They are budgets, not amounts per household or a guarantee of spend.

The government’s stated aims are to upgrade up to five million homes and lift up to one million families out of fuel poverty by 2030. The plan also says new minimum energy efficiency standards will apply to private and social landlords.

The Warm Home Discount is different help. It is a one-off £150 discount off an electricity bill, usually applied automatically if you are eligible. GOV.UK says the Warm Home Discount Scheme reopens in October 2026 for winter 2026 to 2027. Our Warm Home Discount guide covers who gets it and the dates for this winter.

Who qualifies for the Warm Homes Plan

There is no single test, because the plan pays for several schemes. The main free route is the Warm Homes: Local Grant, for privately owned or rented homes in England with an EPC rating of D to G. GOV.UK says household income must usually be £36,000 a year or less, with a qualifying postcode or benefit as other ways in.

Warm Homes: Local Grant, the three ways in

You need to meet one of these. The rules come from the GOV.UK application page and the DESNZ policy guidance for councils.

  • Postcode. Your home is in an area in income deciles 1 or 2 of the Indices of Multiple Deprivation. GOV.UK publishes the list of eligible postcodes.
  • Benefits. Someone in your household receives Housing Benefit, income-based Jobseeker’s Allowance, income-related Employment and Support Allowance, Income Support, Pension Credit or Universal Credit. Households that qualify through route 2 of ECO Flex also count.
  • Income. Your gross household income is £36,000 a year or less. DESNZ also sets an after-housing-costs threshold that depends on household make-up.

GOV.UK says £36,000 or less, while DESNZ’s guidance for councils says below £36,000. If your household income is exactly on the line, ask your council which test it applies.

Home and tenure rules

  • The home must be in England. The Local Grant is not available in Scotland, Wales or Northern Ireland.
  • It must be privately owned, by you or your landlord, and be an existing home. New builds and self-builds that have not been lived in are excluded. Gas and off-gas homes can both qualify, and park homes can qualify if they are the household’s permanent residence.
  • It must have an EPC rating of D, E, F or G. Homes rated A to C are ineligible in all circumstances. You can find your EPC when you apply.
  • Owner-occupiers and tenants are not expected to contribute to the cost. If you rent privately, your landlord has to take part: DESNZ guidance requires a landlord declaration, and a landlord can have one home fully funded with a 50% contribution for further homes.
  • If you rent privately in an F or G rated home, Citizens Advice says the landlord must have registered the property as exempt from the minimum energy efficiency standard. GOV.UK guidance says landlords cannot let a property rated below E without a valid exemption.
  • Social housing is generally excluded, with limited in-fill exceptions that councils control. Citizens Advice suggests asking your social landlord whether they applied for funding through the Warm Homes: Social Housing Fund.

Four illustrative examples

These examples apply the published rules to made-up households. They are not real customers, they use no real outcomes, and none of them promises that a scheme will pay for anything.

Illustrative householdRoute to checkWhy

Housing association tenant in EnglandWarm Homes: Social Housing Fund, through the landlordThe Local Grant generally excludes social housing, so the tenant asks the landlord whether it has applied for funding.

What you can get: heat pumps, insulation, solar and batteries

Insulation, heat pumps, solar panels, batteries and smart controls are all funded somewhere in the plan, but no one scheme pays for everything. The Local Grant covers the widest range. The Boiler Upgrade Scheme pays only for low-carbon heating. Loans cover heat pumps, solar and batteries, but not insulation.

Sources: GOV.UK Local Grant page, DESNZ policy guidance, GOV.UK Boiler Upgrade Scheme page and the Warm Homes Loan Scheme rules.

Warm Homes Plan heat pumps

The Boiler Upgrade Scheme gives £7,500 towards an air source heat pump or a ground source heat pump, £5,000 towards a biomass boiler and £2,500 towards an air-to-air heat pump. Until March 2027 there is an extra £1,500 towards an air source or ground source heat pump if the property is heated by oil or LPG and has no mains gas connection. You cannot get a grant for a hybrid system that combines a gas boiler with a heat pump. Our guide to the air source heat pump grant covers the practical side.

Insulation

Insulation is funded through the Local Grant when a council survey recommends it. The Great British Insulation Scheme, which also paid for insulation, closed on 31 March 2026. Our insulation grant guide explains the measures in more detail.

Will the Warm Homes Plan pay for a new gas boiler?

No. DESNZ guidance for councils says new gas boilers cannot be funded by the Local Grant. In a home on mains gas, a heat pump fitted alongside a new gas boiler can be funded only for the heat pump part. Ofgem says ECO4 can include upgrading a heating system, but only until 31 December 2026. Gas boilers are not banned in existing homes, though. Our gas boiler ban guide explains what the Future Homes Standard changes.

Loans

The Warm Homes Loan Scheme is lender-led and is aimed at owner-occupiers and private landlords. The government pays participating lenders a grant of up to 20% of each loan to support zero and low-interest lending. It does not fund insulation, and the loan caps are £15,000 for solar, £15,000 for a battery and £20,000 for an air-to-water heat pump before any Boiler Upgrade Scheme grant is deducted.

The scheme rules say the first consumer launch phase runs from September 2026. We have not confirmed which lenders are offering loans yet, so ask a lender directly before planning around one.

Is there a free solar panels grant?

Not for everyone. The only free route in the official sources is the Warm Homes: Local Grant, where councils can fit solar panels in eligible low-income homes in England. Other households pay, with help from loans and a zero rate of VAT on solar installations until 31 March 2027.

  • Free through the Local Grant. You must meet the eligibility rules above, your council must have funding, and the home survey must suggest solar. GOV.UK lists solar panels among the improvements a council might arrange.
  • Most common measure so far. DESNZ statistics published on 27 August 2026 say solar PV was 38% of the installations reported by the end of July 2026. The figures are provisional.
  • Loans for everyone else. The Warm Homes Loan Scheme allows loans of up to £15,000 for solar panels and up to £15,000 for a battery. These are loans, so you repay them.
  • VAT. HMRC says the zero rate for installing energy-saving materials, including solar panels and batteries in homes, applies to 31 March 2027. From 1 April 2027 the reduced rate of 5% applies.

Treat adverts that promise free solar panels to every household with caution. Our solar panels grant guide sets out what is and is not funded, and our guide to spotting scams explains how to check an installer, including us.

Warm Homes: Local Grant today

The Warm Homes: Local Grant is the live, free scheme under the plan. DESNZ allocated £500 million for delivery from April 2025 to March 2028, shared across 74 projects covering 271 councils in England. You apply on GOV.UK, and your council arranges a survey and pays for agreed work if it has funding.

How to apply, step by step

  1. Check the home and household rules. Your home must be in England, privately owned or privately rented, with an EPC rating of D to G. Your household must meet the postcode, benefit or income rule.
  2. Apply on GOV.UK. Use the Warm Homes: Local Grant service on GOV.UK. You can call the helpline on 0800 098 7950 if you need help to apply.
  3. Wait for your council to contact you. Your council usually contacts you within 10 working days to get more information and arrange a home survey.
  4. Have the home survey. The survey looks at how your home could be made more energy efficient. The council might suggest insulation, an air source heat pump, smart controls or solar panels.
  5. Agree the work. Your council organises and pays for the improvements you agree. If you have a landlord, they may need to pay for some of the work.

The helpline is open Monday to Friday 8am to 6pm and Saturday 9am to 12pm. Citizens Advice notes that the grant is only available in some areas, so your council decides whether it can help.

What councils can spend per home

DESNZ sets cost caps of £16,600 per home for energy performance upgrades and £16,600 per home for low-carbon heating. Councils must meet the caps on average across a project, so an individual home can cost more or less.

Delivery so far

The August 2026 statistics report around 11,250 measures in around 5,470 households up to the end of July 2026. They are based on returns from 67 of the 74 grant recipients, are provisional, and DESNZ expects revisions to be mainly upward. Solar PV was 38% of installations, insulation about 24% of measures and batteries 18%.

For a closer comparison with ECO4 and the closed insulation scheme, read our Warm Homes Local Grant vs ECO4 guide.

Warm Homes Plan vs ECO4: what replaces ECO4?

ECO4 ends on 31 December 2026 and there will be no ECO5. The government has said there will be no successor supplier obligation. Support for low-income homes instead comes from taxpayer-funded grants, starting with the Warm Homes: Local Grant. The Great British Insulation Scheme already closed on 31 March 2026.

The nine-month extension does not add targets. DESNZ says it gives suppliers more time to meet existing targets and remediate non-compliant installations. In the same response the government said it would put an extra £1.5 billion of grant funding into low-income upgrades instead of a successor obligation.

For the background on the closed insulation scheme, see our Great British Insulation Scheme guide.

How to apply for the Warm Homes Plan

You do not apply to the Warm Homes Plan itself. You apply to the scheme it funds that fits your home. Start with the “which scheme to check first” table above, then act on the route that fits you.

Free eligibility check: ECO4 or Warm Homes

Check whether you may qualify for ECO4 before it closes. If you do, our team surveys your home, installs the measures and submits the work under ECO4. If your answers point to the Warm Homes: Local Grant instead, the checker tells you so and links to the Local Grant service on GOV.UK. We are an installer, not the government, and the choice of who you apply through is yours.

You should not need to pay to apply for the Local Grant. GOV.UK says your council organises and pays for the improvements you agree.

Warm Homes Plan FAQ

The basics

What is the Warm Homes Plan?

It is the UK government’s £15 billion programme, run by DESNZ, to upgrade up to five million homes by 2030.

It is a funding programme, not a single scheme or application form. It pays for low-income grants (around £5 billion to 2030), the Boiler Upgrade Scheme (£2.7 billion), low-interest consumer loans backed by an initial £2 billion of government support, and £1.1 billion for heat networks. DESNZ published it on 21 January 2026 and aims to lift up to one million families out of fuel poverty by 2030. You apply to the individual schemes it funds, such as the Warm Homes: Local Grant, not to the plan.

Is the Warm Homes Plan the same as the Warm Homes: Local Grant?

No. The Local Grant is one of the schemes the Warm Homes Plan pays for.

The Warm Homes Plan is the £15 billion programme. The Warm Homes: Local Grant is the council-run grant inside it that pays for free upgrades in eligible low-income homes in England, delivered until 31 March 2028. The plan also funds the Boiler Upgrade Scheme, the Warm Homes Loan Scheme and the Warm Homes: Social Housing Fund. You apply to one of those schemes, not to the plan.

When does the Warm Homes Plan start?

It has already started: DESNZ published it on 21 January 2026, and councils are delivering the Local Grant now.

The Warm Homes: Local Grant runs until 31 March 2028 where your council has funding. The Warm Homes Loan Scheme rules put the first consumer launch phase from September 2026, although we have not confirmed which lenders are live. The government intends to merge its low-income schemes into one area-based scheme from 2027/28, but the rules and start date have not been announced in the sources we checked.

Does the Warm Homes Plan apply in Scotland, Wales and Northern Ireland?

Partly. The Local Grant is England only, but the heat pump grant covers Wales and the loan scheme covers the whole UK.

The Boiler Upgrade Scheme covers England and Wales. The Warm Homes Loan Scheme is open to owner-occupiers and private landlords anywhere in the UK. Scotland, Wales and Northern Ireland run their own home energy schemes, and GOV.UK links to them. ECO4 covers Great Britain until 31 December 2026, so households in Scotland and Wales can still check it before it closes.

Who qualifies for the Warm Homes Plan?

It depends on the scheme, and the main free route is the Warm Homes: Local Grant for homes in England.

For the Local Grant your home must be privately owned or privately rented, in England, with an EPC rating of D to G. GOV.UK says household income must usually be £36,000 a year or less, but you can still qualify on a higher income if you live in a qualifying postcode area or someone in the household gets certain benefits. Your council must also have funding. Heat pump grants and loans have separate rules, and the loan scheme has no income threshold.

Is there a free solar panels grant in the UK?

Only through the Warm Homes: Local Grant, where a council can fit solar panels in eligible low-income homes in England.

GOV.UK lists solar panels among the improvements a council might suggest after a home survey, and the council pays for the work you agree. It depends on council funding and what the survey recommends. Everyone else pays, although the Warm Homes Loan Scheme allows loans of up to £15,000 for solar and HMRC applies a zero rate of VAT to installing solar panels until 31 March 2027. DESNZ statistics say solar was the most common measure delivered so far, at 38% of installations.

What replaces ECO4 in 2027?

No supplier scheme replaces it: there is no ECO5, and taxpayer-funded grants take over.

DESNZ says there will be no successor supplier obligation to ECO4 and has committed £1.5 billion of extra grant funding for low-income households instead. ECO4 ends on 31 December 2026. The live grant route is the Warm Homes: Local Grant, delivered to March 2028, and the government intends to merge its low-income schemes into one area-based scheme from 2027/28. We have not found the rules for that scheme in official sources, so treat the 2027 detail as not yet announced.

Is the Warm Homes Plan the same as the Warm Home Discount?

No, the Warm Home Discount is a one-off £150 discount off an electricity bill.

You will usually get it automatically if you are eligible, although you may need to apply directly to your energy supplier. GOV.UK says the scheme has closed and will reopen in October 2026 for winter 2026 to 2027. The Warm Homes Plan is the wider upgrade programme. The discount lowers one bill, while the Local Grant pays for improvements to the home itself, so it is worth checking both.

Applying and getting help

How do I apply for the Warm Homes Plan?

Apply for the Warm Homes: Local Grant on GOV.UK, and your council usually contacts you within 10 working days.

The GOV.UK service lets you check your eligibility and find your EPC if you do not know it. If you need help, call the helpline on 0800 098 7950 (Monday to Friday 8am to 6pm, Saturday 9am to 12pm). If your council has funding, it arranges a home survey, then organises and pays for the work you agree. Citizens Advice says the grant is only available in some areas, so confirm with your council.

Is there Warm Homes Plan funding for landlords?

Yes. Private landlords can use the Local Grant and the Warm Homes Loan Scheme, with some conditions.

Under the Local Grant, DESNZ guidance lets a private landlord have one home fully funded, with a 50% landlord contribution for further homes, and the landlord must complete a declaration. Tenants are not expected to contribute. If the home is rated F or G, the landlord must have registered a valid exemption from the minimum energy efficiency standard. The Warm Homes Loan Scheme is open to private landlords for heat pumps, solar and batteries. The plan also says new minimum energy efficiency standards will apply to private and social landlords.

How do I get a heat pump grant?

Apply for the Boiler Upgrade Scheme, which gives £7,500 towards an air source or ground source heat pump in England and Wales.

The GOV.UK page also lists £5,000 towards a biomass boiler and £2,500 towards an air-to-air heat pump, with one grant per property. Until March 2027 there is an extra £1,500 towards an air source or ground source heat pump if your property is heated by oil or LPG and has no mains gas connection. You cannot get a grant for a hybrid system that combines a gas boiler with a heat pump.

How do I get a loan for solar panels, a battery or a heat pump?

Ask a participating lender under the Warm Homes Loan Scheme, which is open to owner-occupiers and private landlords anywhere in the UK.

Government pays lenders a non-repayable grant of up to 20% of each loan, which supports zero and low-interest lending. Loan caps are £15,000 for solar, £15,000 for a battery and £20,000 for an air-to-water heat pump before any Boiler Upgrade Scheme grant is deducted. It does not fund insulation, and lenders run their own affordability and credit checks. The rules put the first consumer launch phase from September 2026, but we have not confirmed which lenders are live.

Who qualifies for ECO4 before it closes, and what evidence is needed?

Owners and private tenants who get an income-based benefit and whose home has a low enough EPC rating, according to Citizens Advice.

Citizens Advice lists Universal Credit, Pension Credit, Housing Benefit, income-based Jobseeker’s Allowance, income-related Employment and Support Allowance and Income Support. Owners need an EPC of D to G, and private tenants need E to G. Councils may also help under ECO Flex, for example if household income is under £31,000, but not all councils offer it. A council or supplier might ask for evidence such as a letter from the benefit office or payslips, so ask to read their privacy policy if you are unsure.

How do I check an installer is genuine?

Check the company number, ask which scheme the work is submitted under, and ask what you will pay, if anything, before you agree.

Citizens Advice says adverts and cold calls offering ECO funding can be hard to judge, and it recommends applying through your council or an energy supplier. We are an installer, and our company details are on Companies House (Reliant Energy Solutions Ltd, company number 16100301). For heat pumps and solar under the Local Grant, DESNZ guidance requires installers to be MCS certified. Our guide to spotting free boiler grant scams has more checks.

When things go wrong

My council says it has no Local Grant funding. What can I do?

Ask what else it offers, then check ECO4 before it closes, the Boiler Upgrade Scheme or a loan.

DESNZ says funding has been allocated to 74 projects covering 271 councils, which is over 97% of eligible councils in England, yet Citizens Advice still says the grant is only available in some areas. Citizens Advice also notes that not all councils offer ECO Flex. You can apply to ECO4 through an energy supplier until it ends on 31 December 2026, although suppliers might stop earlier. If you rent, Citizens Advice suggests asking your landlord to apply to other schemes.

My home is rated EPC C or higher. Can I still get help?

Not from the Warm Homes: Local Grant, which excludes homes rated A to C in all circumstances.

That rule comes from DESNZ guidance for councils, so a council has no discretion over it. The Warm Homes Loan Scheme works differently: it has no income threshold and no scheme-level restriction by property type. The Boiler Upgrade Scheme has its own rules on GOV.UK. Check your current EPC before you apply, and note that the Local Grant service can find it for you.

I rent privately and my EPC is F or G. Can I apply?

Only if your landlord has registered the property as exempt from the minimum energy efficiency standard.

Citizens Advice describes this extra rule for the Local Grant, and GOV.UK guidance says landlords cannot let a property rated below E without a valid exemption. DESNZ guidance also requires private landlords to complete a declaration. A landlord can have one home fully funded, with a 50% landlord contribution for further homes, and tenants are not expected to contribute. If the exemption is not registered, Citizens Advice suggests talking to an adviser.

I was told ECO4 is closed. Is that right?

Not officially: ECO4 runs to 31 December 2026, although suppliers and councils can stop taking applications earlier.

Ofgem says ECO4 will run until 31 December 2026 following a nine-month extension, and Citizens Advice says to start as soon as you can. Ask whoever told you when they stopped taking applications. No official source we checked says ECO4 will continue into 2027, because DESNZ has said there will be no successor supplier obligation. The Local Grant runs to March 2028 where your council has funding.

An installer wants a payment upfront or says I qualify without checking. What should I do?

Treat it as a warning sign and do not agree to the work until you know what, if anything, you will pay.

For the Local Grant, GOV.UK says your council organises and pays for the agreed work and you will not need to pay for it, although a landlord may need to pay for some. Citizens Advice says ECO should normally cover all the costs, but the council or supplier might ask you or your landlord to pay something, and they should tell you how much before you agree. If you have not agreed, tell the installer you will not agree to it. You might be able to cancel if you have.

About this page

Who runs this site. ApplyFreeBoiler.uk is run by Reliant Energy Solutions Ltd, company number 16100301, registered at 15 Cardigan Drive, Bury, BL9 9LG. Companies House lists it as incorporated on 25 November 2024. It is an ECO4 heating and insulation installer that surveys homes, installs the work and submits it under ECO4.

Conflict of interest. We install under ECO4, so we gain when people check and use ECO4 before it closes. That is why this page names the other routes, says what each one pays for, and tells you plainly that ECO4 has no successor.

How we checked it. On 7 October 2026 we read the primary documents listed below, from GOV.UK, DESNZ, Ofgem, HMRC, Citizens Advice and Companies House. We did not take rules or figures from comparison sites or other installers. Where sources differ, we say so, and where we could not confirm something, we mark it as not yet announced.

Review and updates. This page was written by the ApplyFreeBoiler Team and reviewed by the company director, Reliant Energy Solutions Ltd. It follows our editorial policy. We re-check it when the government publishes new rules, and we will review it again after ECO4 ends on 31 December 2026.

Changelog. 7 October 2026: rewritten around official sources, with a confirmed and not-yet-announced timeline, updated ECO4 and Local Grant figures, and a new FAQ. 11 August 2026: first published.

Summary

The Warm Homes Plan is a funding programme, and the free route for low-income households is the Local Grant in England. ECO4 ends on 31 December 2026 with no ECO5, and the 2027 low-income scheme has not been detailed yet. If you might qualify for ECO4, check now.
