Heat Pump Grants – What You Need To Know

A heat pump is a mechanical device or system that is used for heating or cooling spaces by transferring heat from one location to another. It moves heat from a source to a destination rather than generating heat directly, which makes it an energy-efficient heating and cooling solution.

If you want to install a heat pump in your home, Warmable can connect you to a qualified local engineer for free. There a number of grants and schemes you could be eligible for – check out the options below. Then simply fill in our quick form and a member of our team will be in touch shortly.

UK Government Grants For Heat Pumps 


  • Energy Company Obligation Scheme: This program provides support for energy-efficient home improvements, which may include heat pump installations.
  • Boiler Upgrade Scheme: This scheme offers financial assistance for the installation of air source and ground source heat pumps, with increased grant amounts as of October 23, 2023.
  • Warmer Homes Scotland: Through this scheme, eligible homeowners may have the opportunity to receive a free heat pump, among other home energy improvements.
  • Home Energy Scotland Scheme: This scheme offers support for various energy-saving measures, which could include heat pump installations.
  • Nest Scheme (Wales): In Wales, the Nest Scheme provides financial aid for home energy improvements, and this may include heat pump installations.

These government grants also cover other home improvement solutions. Therefore, the availability of funds for heat pumps can be limited and works on a first-come, first-served basis. 

Some incentives, such as Warmer Homes Scotland and the Nest Scheme in Wales, may offer free heat pumps to eligible homeowners. However, it’s essential to meet the eligibility criteria for these grants.

ECO4, or the Energy Company Obligation Phase 4, is the latest phase of the UK government’s initiative aimed at reducing household carbon emissions and improving energy efficiency in homes. ECO4 commenced on April 1, 2022, and is expected to continue until March 2026.

The extent and type of home improvements you can receive under ECO4 will depend on your household’s specific needs and the energy supplier you collaborate with. The program is designed to make energy-efficient upgrades more accessible to a wider range of households and contribute to the UK’s goals for reducing carbon emissions and improving overall energy efficiency in homes.

Under ECO4, various energy-saving measures are covered, including:

  • Boiler Repairs: This may involve repairing or upgrading existing heating systems to improve their efficiency and reduce emissions.
  • Insulation: The program supports the installation of insulation in homes to reduce heat loss and improve energy efficiency.
  • Replacing Inefficient Heating Systems: Inefficient heating systems, such as those powered by fossil fuels, can be replaced with low-carbon heating systems, like air source heat pumps and biomass boilers. These alternatives are more eco-friendly and energy-efficient.

Am I Eligible for ECO4?

To be eligible for ECO4, you typically need to meet the following criteria:

  • Inefficient Heating System: Your home should have an inefficient heating system that falls within the D-G energy efficiency band. This means that your current heating system is less energy-efficient, and it needs an upgrade to improve energy efficiency and reduce carbon emissions.
  • Homeownership or Private Rented Accommodation: You must either own your home and live in it or live in private rented accommodation. ECO4 is generally available to both homeowners and tenants in private rented properties.
  • All-Electric Homes: ECO4 eligibility often extends to all-electric homes, both those connected to the gas supply and those off-gas. In cases where biomass boilers or District Heat Networks are not viable options, you may qualify for energy efficiency improvements.
  • Receiving Government Benefits: Being in receipt of certain government benefits, such as child benefits or income support, can also be a factor that determines eligibility. This is often used to target assistance to households with lower incomes or in vulnerable situations.

Boiler Upgrade Scheme


The Boiler Upgrade Scheme is a government initiative introduced as part of a larger £3.9 billion funding package unveiled in the Heat and Buildings Strategy. This program is aimed at reducing the carbon footprint of homes in the UK. The scheme was officially launched in April 2022 and is set to remain in effect until 2028.

The primary objective of the Boiler Upgrade Scheme is to incentivize homeowners in England and Wales to transition to more energy-efficient and eco-friendly heating systems, such as air source heat pumps and ground source heat pumps. Under this scheme, eligible homeowners can receive financial support of up to £7,500 for the installation of these heat pump systems.

This scheme is a successor to the Domestic Renewable Heat Incentive (RHI) Scheme, which closed to new applications on March 31, 2022. The financial assistance offered by the Boiler Upgrade Scheme is substantial, as it can cover a significant portion of the supply and installation costs. 

Specifically, the scheme can contribute to approximately 60% of the total expenses for an air source heat pump installation and approximately 25% of the cost for a ground source heat pump installation. This means that, in practice, the scheme can make the cost of installing a £10,000 air source heat pump equivalent to the cost of installing a new boiler.

Am I Eligible for the Boiler Upgrade Scheme ?

The eligibility criteria for the Boiler Upgrade Scheme are as follows:

  • Homeownership or Landlord Status: You must be a homeowner, small landlord, or private landlord in England or Wales.
  • Valid Energy Performance Certificate (EPC): You need to have a valid Energy Performance Certificate (EPC) that does not have any outstanding loft or cavity wall insulation recommendations.
  • Heating System Replacement: You should not be replacing an existing low-carbon heating system. The scheme is specifically for replacing fossil fuel heating systems, such as those powered by oil, gas, or direct electric heating.
  • Installation Capacity: Your heating system must have an installation capacity up to 45kWth, which is the case for the majority of properties in the UK.

How to Apply for the Boiler Upgrade Scheme

The boiler upgrade scheme is applied for on behalf of your chosen installer through Ofgem. Explore the government site for more information.
