Miliband Heat Pump Subsidy Plan Explained

Miliband Heat Pump Subsidy Plan: What It Means for UK Households

The Miliband heat pump subsidy plan is part of the government’s £15 billion Warm Homes Plan. It is not one new grant with a single application form. It combines the expanded Boiler Upgrade Scheme, support for lower income homes and a new affordable finance programme.

Homeowners in England and Wales can currently receive £7,500 towards an eligible air to water or ground source heat pump. Qualifying homes replacing oil or LPG heating can receive £9,000 until 31 March 2027. A separate £2,500 grant is available for eligible air to air heat pumps.

The policy also includes the Warm Homes Loan Scheme, which is being introduced through approved lenders, and free improvements for some lower income households. Different rules apply across England, Wales, Scotland and Northern Ireland.

This guide separates the support you can use now from measures that are still being developed.

What Is the Miliband Heat Pump Subsidy Plan?

The phrase refers to the clean heating measures announced under the Warm Homes Plan by Energy Secretary Ed Miliband. The plan was officially published in January 2026 and later supported by changes to the Boiler Upgrade Scheme.

Its purpose is to reduce the upfront cost of heat pumps, solar panels, batteries and other home energy improvements. The government also wants to increase heat pump installations to more than 450,000 a year by 2030.

The plan has three main forms of household support:

1. Grants: Money towards an eligible heat pump through the Boiler Upgrade Scheme.

2. Free improvements: Tailored packages for qualifying lower income households and social housing.

3. Affordable finance: Government supported loans for households that can repay finance but cannot easily meet the full upfront cost.

This means two households may receive very different offers. One might receive a fixed heat pump grant, another might qualify for a complete council funded package, and another may use a grant with a loan for the remaining cost.

How Much Money Is Behind the Warm Homes Plan?

The government has allocated £15 billion to the wider Warm Homes Plan. This is spread across several programmes rather than being available as one household grant fund.

The figures cover several years and include money for delivery, finance and market development. They do not mean every household can claim a share of £15 billion directly.

What Heat Pump Subsidies Are Available Now?

The Boiler Upgrade Scheme is the main subsidy available to property owners in England and Wales. It reduces the installer’s invoice instead of paying cash to the household.

The standard £7,500 grant applies when an eligible homeowner replaces a mains gas system with an air to water or ground source heat pump. The higher £9,000 rate is aimed at qualifying homes that do not have a mains gas connection and are replacing oil or LPG heating.

Read the complete Boiler Upgrade Scheme guide before requesting quotations.

Who Can Get the £7,500 Heat Pump Grant?

You normally need to own the property. This can include your main home, a second home, a qualifying small business property or a home that you rent to tenants.

The grant is available without an income test. Your salary, savings and benefit status do not decide whether you can use the standard Boiler Upgrade Scheme.

The proposed installation and property must still meet the technical rules. Important conditions include:

• You must be replacing an eligible existing heating system

• The property must be in England or Wales

• The installation must use an MCS certified installer

• The selected equipment must meet the scheme’s standards

• The new system must provide the required space heating

• You cannot receive two government grants for the same heat pump installation

• Most unfinished new builds and social housing properties are excluded

The old rule requiring an EPC with no outstanding loft or cavity wall insulation recommendations was removed from the Boiler Upgrade Scheme in April 2026. Insulation is still important for comfort and running costs, but that previous application barrier no longer applies.

How the application works

You do not submit the voucher application yourself. After assessing your property and providing a quotation, your MCS certified installer applies to Ofgem on your behalf.

You confirm your consent and property details. If the application is accepted, the grant is deducted from the amount you pay. The installer later redeems the voucher after completing and commissioning the system.

Who Qualifies for the £9,000 Heat Pump Grant?

The £9,000 rate is a temporary increase for certain properties replacing oil or LPG heating. It became available on 21 July 2026 and is scheduled to end on 31 March 2027.

To qualify, the property must meet the off gas grid rules. It must not have a mains gas meter point or be connected to a heat network. The heating system being replaced must use oil or LPG.

The uplift applies to an eligible air to water or ground source heat pump. It does not raise the air to air heat pump grant above £2,500.

A rural postcode by itself is not enough. The installer must provide the evidence required to show the property and existing heating system meet the uplift rules.

The higher subsidy can bring the remaining cost closer to the price of replacing an oil boiler, but it does not guarantee a free installation. Radiators, electrical work, hot water equipment and groundworks can all affect the final quotation.

Check Which Heat Pump Support Fits Your Home

Answer a few simple questions about your location, property ownership and current heating system.

Check Your Grant Options

Free to check with no obligation. Final approval depends on the official scheme and property assessment.

What Is the £2,500 Air to Air Heat Pump Grant?

Air to air heat pumps became an eligible Boiler Upgrade Scheme category in April 2026. They use indoor fan units to distribute warm air rather than sending heated water through radiators.

Many systems can also cool rooms during warmer weather. This is why they are sometimes described as air conditioning heat pumps.

An air to air system does not normally provide domestic hot water. The property will need a separate hot water arrangement, such as an electric cylinder.

This option may suit flats, smaller homes and properties that currently use electric panel or storage heating. Suitability depends on the design, number of indoor units and whether the system will meet the required space heating demand.

The lower £2,500 grant reflects the different equipment and typical installation cost. It should not be confused with the £7,500 grant for an air to water heat pump.

Does the Plan Include a £2,500 Heat Battery Grant?

A £2,500 heat battery grant has been announced, but households should not assume that it is currently available.

The government intends to add heat batteries after suitable product, design and installation standards are introduced. The official Boiler Upgrade Scheme grant categories in force on 27 September 2026 do not yet list heat batteries.

This distinction matters because some websites describe the announced amount as an active grant. An announcement of future support is not the same as an open application route.

Do not sign a contract based on the expectation of a £2,500 heat battery payment unless the installer can show that applications have officially opened and that the chosen product is eligible.

What Is the Warm Homes Loan Scheme?

The Warm Homes Loan Scheme is the finance part of the policy. It is designed for owner occupiers and private landlords who can repay borrowing but need help with the upfront cost of home energy improvements.

It is a loan rather than a grant. A participating bank or lender provides the finance and carries out its normal credit and affordability checks. Government support is used to reduce the cost of that borrowing.

The wider Warm Homes Plan includes £2 billion for low interest consumer lending. The initial lender programme uses £300 million of grant capital to help lenders reduce finance costs.

What can the loan support?

Current scheme rules include support for measures such as:

• Eligible air to water heat pumps

• Ground and water source heat pumps

• Solar photovoltaic panels

• Home battery storage

• Certain biomass boilers

• Connections to eligible low carbon heat networks

Published scheme limits include up to £20,000 for an air to water heat pump and up to £35,000 for a ground or water source heat pump. These are programme limits, not guaranteed loan offers. The lender decides how much it is prepared to lend.

Can the loan be combined with a heat pump grant?

The scheme is designed to work with an applicable Boiler Upgrade Scheme or devolved nation grant. For example, an eligible homeowner may use a £7,500 heat pump grant and finance some of the remaining installation cost through an approved loan.

The grant and loan have separate eligibility requirements. Receiving a Boiler Upgrade Scheme voucher does not guarantee that a lender will approve your finance application.

Can households apply now?

The government has completed the first lender application window and is onboarding participating lenders. As of 27 September 2026, there is no single public application portal listing a universal rate available from every lender.

Actual interest rates, terms and public launch dates depend on participating lenders. Be cautious of an installer claiming to offer a guaranteed government loan without naming the regulated lender and providing the full credit agreement.

Can Lower Income Households Get a Heat Pump Free?

Some lower income households may receive a heat pump through a funded home improvement package rather than using the standard £7,500 subsidy.

Warm Homes Local Grant

This scheme operates through local authorities in England. It supports privately owned homes with an EPC rating of D, E, F or G.

Household income usually needs to be £36,000 a year or less. A property may also qualify through an eligible postcode or benefit route.

The council arranges a home assessment and decides which improvements are suitable. The package can include insulation, solar panels, controls and an air source heat pump. Eligible owner occupiers do not pay for measures approved by the council, although a private landlord may need to contribute.

ECO4

ECO4 can fund heating and insulation improvements for qualifying homes in England, Scotland and Wales. It currently runs until 31 December 2026.

Eligibility may come through a qualifying benefit, ECO4 Flex or certain social housing rules. ECO4 is controlled by energy suppliers, so eligibility does not guarantee a heat pump or a fully funded package.

Social housing support

The Warm Homes Social Housing Fund provides money to councils and housing associations for energy improvements. Tenants generally do not apply for an individual grant. Their housing provider selects eligible properties and arranges the work.

Does the Miliband Plan Force Households to Install Heat Pumps?

No. The current subsidy plan does not require an existing homeowner to remove a working gas boiler and install a heat pump.

The Boiler Upgrade Scheme is voluntary. A property owner chooses whether to request quotations and proceed with an installation.

Rules affecting heating in newly built homes are separate from grants for existing properties. Standards for new construction do not create an automatic requirement for every existing household to replace its boiler.

The Clean Heat Market Mechanism also applies to heating manufacturers rather than forcing an individual household to purchase a heat pump. It encourages manufacturers to increase sales of clean heating systems.

A landlord may face energy efficiency duties for a rented property, but this does not mean every landlord must install a heat pump immediately. The required work depends on the regulations, property and available exemptions.

Will a Heat Pump Always Reduce Energy Bills?

No responsible installer can guarantee a specific saving before assessing the property.

A heat pump can produce several units of heat from one unit of electricity. However, electricity usually costs more per unit than gas. The final running cost depends on the seasonal efficiency of the system and the tariff used.

The government estimates that some households can save money when a well designed heat pump is combined with a suitable flexible tariff. Greater savings may be possible when solar panels and battery storage are also installed.

Results depend on:

• The home’s heat loss

• Insulation and draught control

• Heat pump size and design

• Radiator or underfloor heating capacity

• Flow temperature

• Hot water demand

• Electricity and gas prices

• The tariff and time when electricity is used

• How the household controls the system

A grant reduces the installation cost. It does not correct poor system design or guarantee lower bills.

Compare the wider UK options in the Heat Pump Grants UK guide.

How the Plan Applies Across the UK

Announcements using UK wide totals can therefore be confusing. Funding may contribute to devolved budgets, while the household application routes remain different in each nation.

What the Policy Means for Different Households

Home heated by mains gas

An eligible owner in England or Wales can receive £7,500 towards an air to water or ground source heat pump. The household pays the remaining cost unless another eligible scheme covers it.

Home heated by oil or LPG

An eligible off gas grid property in England or Wales can receive £9,000 for an air to water or ground source heat pump until 31 March 2027.

Home using electric panel or storage heating

The property may suit an air to air heat pump, which currently has a £2,500 grant, or an air to water system with the standard £7,500 grant. A detailed assessment is necessary because hot water must also be considered.

Lower income owner occupier

Check council and supplier funded schemes before taking a loan. A qualifying household could receive a funded package through the Warm Homes Local Grant, ECO4 or a devolved programme.

Private landlord

A landlord can potentially use the Boiler Upgrade Scheme for an eligible rental property. Future Warm Homes loans are also intended to support private landlords borrowing personally, subject to the lender’s requirements.

Private tenant

A tenant cannot claim the Boiler Upgrade Scheme independently because the property owner controls the application. The household may qualify for ECO4 or local support, but landlord consent is required for installation work.

Social housing tenant

Contact the housing association or council. Social landlords use separate funding programmes and usually select properties through planned improvement projects.

How to Check Whether a Heat Pump Is Right for Your Home

1. Check your current heating: Record whether you use mains gas, oil, LPG or electric heating.

2. Confirm ownership: The Boiler Upgrade Scheme is claimed for the property by its owner.

3. Arrange more than one survey: Compare proposals from MCS certified installers.

4. Request a heat loss calculation: The system should be designed room by room.

5. Check radiators and pipework: Find out which parts require upgrading.

6. Review hot water needs: Confirm the proposed cylinder capacity and recovery time.

7. Compare running cost estimates: Ask which electricity tariff and efficiency assumptions were used.

8. Confirm the grant: Make sure the correct subsidy is deducted from the quotation.

9. Read the contract: Check warranties, exclusions, payment stages and complaint procedures.

A good installer should explain why the recommended system size suits the property. A quotation based only on floor area or bedroom count is not enough for a reliable design.

Safety and Misinformation Checks

Political policy announcements often produce misleading advertising. Some companies combine active grants, planned finance and future technologies into one offer that appears more generous than the actual schemes.

• Do not pay a fee to “release” government grant money

• Do not accept a guaranteed approval before a property assessment

• Check that the installer holds current MCS certification

• Confirm that the quotation shows the grant deduction

• Treat the Warm Homes Loan as repayable borrowing

• Ask for the lender’s name, interest rate and total repayment

• Do not assume the heat battery grant is open

• Do not accept claims that a heat pump is compulsory for your existing home

For the policy, funding allocations and official household offer, read the government’s Warm Homes Plan.

Frequently Asked Questions

What is the Miliband heat pump subsidy plan?

It is the collection of heat pump grants, lower income home improvements and affordable finance measures included in the government’s Warm Homes Plan. It is not one separate grant called the Miliband subsidy.

Can everyone get £7,500 for a heat pump?

The Boiler Upgrade Scheme has no income test, but the applicant, property, existing heating system and installation must satisfy its rules. It is available to qualifying property owners in England and Wales.

Who can get the £9,000 heat pump grant?

The temporary £9,000 rate applies to eligible off gas grid properties replacing oil or LPG heating with an air to water or ground source heat pump. It is available from 21 July 2026 until 31 March 2027.

Is the £9,000 grant available for replacing a gas boiler?

No. An eligible property replacing mains gas heating normally receives the standard £7,500 rate for an air to water or ground source heat pump.

Do I need to receive benefits?

No benefits are required for the Boiler Upgrade Scheme. Income and benefits matter for programmes such as the Warm Homes Local Grant and ECO4.

Is the Warm Homes Loan free money?

No. It is repayable finance from an approved lender. Government support is intended to reduce borrowing costs, but the borrower must repay the loan under the lender’s agreement.

Can a grant and loan be used together?

The Warm Homes Loan Scheme is designed to work with an applicable heat pump grant, subject to the rules of both programmes and the lender’s approval.

Can I apply for a £2,500 heat battery grant now?

Not yet based on the official grant categories in force on 27 September 2026. The government intends to introduce this support after suitable standards and consumer protections are ready.

Will I be forced to replace my gas boiler?

The current plan does not force an existing homeowner to replace a working boiler. Household grant applications are voluntary.

Does Scotland receive the £7,500 Boiler Upgrade Scheme grant?

No. Scotland has its own support through Home Energy Scotland and Warmer Homes Scotland. ECO4 also operates in Scotland until the end of 2026.

Will a heat pump definitely lower my bills?

No saving can be guaranteed. Bills depend on system design, property heat loss, electricity tariff, heating controls and household behaviour.

What Households Should Do Next

If you are ready to install a heat pump, you do not need to wait for every part of the Warm Homes Plan. The Boiler Upgrade Scheme and several lower income programmes are already operating.

Start with your current heating fuel, property location and ownership status. Then compare at least two properly designed quotations and check whether another scheme could cover more of the cost before considering repayable finance.

If you are waiting for a Warm Homes Loan, wait for a named regulated lender to publish its rate and terms. Do not make a financial decision based only on an expected launch date or an installer’s estimated monthly payment.
