The cost of living has increased due to global inflation. This became more noticeable after COVID-19. Energy bills also increased due to higher demand.
In winter, the demand for gas rises because people use more heating systems. Many UK homes now use modern boilers. These are more energy efficient and reduce energy bills. They also support a cleaner environment by lowering carbon emissions.
However, low-income households often cannot afford the upfront cost of installing a new boiler or heat pump. To solve this issue, the UK government introduced the boiler upgrade scheme grant, also known as the BUS scheme.
This government funding helps homeowners replace old systems with a low-carbon heating system, such as heat pumps and biomass boilers. In this blog, we will explain how the boiler upgrade scheme works, the eligibility criteria, the funding, and how to apply for the Boiler Upgrade Scheme.
What is the Boiler Upgrade Scheme?
The boiler upgrade scheme is a UK government grant launched in 2022 by the Department for Energy Security and Net Zero. It aims to reduce carbon emissions by replacing existing fossil fuel heating systems, like a gas boiler or oil boiler, with renewable energy systems. These include:
- Air source heat pump
- Ground source heat pump
- Biomass boiler
This boiler replacement scheme supports low-carbon heating and improves home energy efficiency across UK homes. The scheme provides upfront capital grants to reduce the cost of installing a heat pump or biomass boiler.
How Does the Boiler Upgrade Scheme Work?
Understanding how the boiler upgrade scheme works is simple.
- You contact an MCS-certified installer
- The installer checks your eligibility
- They provide a quote for cost and installation
- If you agree, the installer will apply for the grant on your behalf through Ofgem
- You receive a voucher that reduces the upfront cost
- The grant is deducted from your total bill
This means you only pay the remaining upfront cost of installing your new low-carbon heating system.
How Much Funding Can I Get with the BUS?
Many homeowners ask: How much funding can I get with the BUS?
Here is the updated funding:
- £7,500 for an air source heat pump
- £7,500 for ground source heat pump
- £5,000 for biomass boiler
- £2,500 for air-to-air heat pumps
- £2,500 for heat batteries
This funding goes directly towards the cost of replacing a fossil fuel heating system with a new energy-efficient heating system. It helps reduce the upfront capital cost.

Signs You Need a Boiler Upgrade
Sometimes your boiler may still work, but it may not be efficient.
Here are signs you need a boiler replacement:
1. Using Old Boiler
If your boiler is over 15 years old, it is less efficient.
2. Rising Energy Bills
Old systems use more fuel and increase energy bills.
3. Frequent Repairs
High repair costs mean your boiler is failing.
4. Strange Noises
Unusual sounds may indicate internal problems.
5. Leaks or Corrosion
Leaks reduce efficiency and damage the system.
6. Slow Heating
Rooms take longer to heat, showing reduced performance.
Replacing your existing fossil fuel boiler with a low-carbon heating system improves comfort and saves money.

The boiler upgrade scheme grant is a great opportunity for UK homeowners. It helps replace fossil fuel heating with energy-efficient and eco-friendly systems. By understanding how the scheme works, checking your eligibility, and choosing an MCS-certified installer, you can easily apply for the grant.
With reduced upfront cost, better heating, and lower energy bills, the scheme provides long-term benefits. If you are planning a boiler upgrade, now is the right time to apply for the grant and move towards a low-carbon future.
FAQs
Though the scheme seems to be never-ending because the government’s target is to make net-zero emissions by 2050. However, the first phase of the scheme will end in December 2027.
Not just the savings in upfront cost with up to £7,500 via the government scheme, the upgrade can also bring much more savings in the long run if combined with solar panels.
Basically, the UK government supports the scheme while providing all funding through Ofgem.
In the United Kingdom, boiler upgrade costs range from £12,000 to over 25,000 based on various factors, including property size, heating system capacity, and other requirements.
