Boiler Upgrade Scheme UK

If you own a UK property and are considering upgrading your heating system, now is the time to do so. The government has implemented a boiler upgrade scheme encouraging you to opt for low-carbon heating systems.

This blog will explain everything you need to know about the government boiler scheme, from eligibility to make a claim.

What is The Boiler Upgrade Scheme?

The boiler upgrade scheme is part of the UK’S heating and building strategy. The strategy aims to decarbonise homes, commercial, industrial, and public sector buildings by 2050.

The schemes provide grants to help property owners fund the costs and installation of:

  • An air-source heat pump
  • A biomass boiler
  • A ground source heat pump

Existing low-carbon heating systems cannot be replaced with funding.

How Much Can I Claim?

The amount claimable depends on the type of low-carbon heating system. Please refer to our table below

Type of low carbon-heating systemAmount claimable
  An air-source heat pump  £5,000 off the cost and installation
  A biomass boiler  £5,000 off the cost and installation
  A ground source heat pump  £6,000 off the cost and installation

The new heating system must:

  • Be installed and thoroughly checked by your installer on or after April 1, 2022
  • It needs to meet your property’s needs for heating and hot water.
  • Replace a system that uses fossil fuels to heat
  • It is required to fulfil certain minimum efficiency criteria and other technical standards, which your installer will know.

When can I make a claim?

The boiler upgrade scheme will be from 2022 to 2025
