What Is The Boiler Upgrade Scheme? (All You Need to Know)

With climate change and global warming ever-present threats, more countries are participating in the challenge of reducing carbon emissions. The UK, following suit, formulated several initiatives and policies to achieve greener and cheaper energy production.

The Boiler Upgrade Scheme, previously known as the Clean Heat Grant, is one such programme. It’s a grant initiative launched by the UK government in May 2022.

But what is the Boiler Upgrade Scheme? And what can you expect to gain for applying?

This article will cover the details of the Boiler Upgrade Scheme. We’ll discuss the scheme’s purpose, how much you could receive, the eligibility requirements, and how to apply.

Boiler Upgrade Scheme (BUS) Overview

The Boiler Upgrade Upgrade scheme is a UK-funded programme that aims to help decarbonise homes and small domestic buildings. It’s part of the government’s Heat and Buildings Strategy, dedicated to removing gas boilers from UK homes.

The goal is to encourage homeowners to transition from fossil fuel heating systems like natural gas, oil, and electric to more efficient, low-carbon heating systems.

By applying to the Boiler Upgrade Scheme, you could get a grant to cover part of the costs of replacing your home’s heating system. The scheme is available to people in England and Wales starting May 23, 2022 and will close at the end of December 2024.

What Technologies Does the Boiler Upgrade Scheme Cover?

The focus of the initiative is the replacement of traditional gas boilers with more effective heat pumps. Currently, grants are available for the installation of the following boiler types:

  • Air source heat pump
  • Biomass boiler
  • Ground source heat pump

Shared ground loops and water source heat pumps fall under the ground source category. As such, you can apply for the scheme if you have one.

However, the grant doesn’t apply to hybrid heating systems. These systems use combinations of two or more heating technologies, such as air-source heat pumps and gas boilers.

Moreover, the scheme only includes biomass boiler upgrades in rural areas disconnected from the gas grid. Applying property owners should also provide an emission certificate showing minimum pollution emission.

How Much Funding Can You Receive?

Each applicant can get one Boiler Upgrade Scheme grant per property. The funding you can get from the programme will depend on the type of boiler upgrade you plan to have.

Before the scheme’s amendment, the highest amount eligible applicants could get was £6,000 for ground source heat pumps. Funding for biomass and air source boiler installation was only £5,000.

However, in September 2023, the UK prime minister announced an update on the BUS grant. Strengthening its support for the country’s transition to Net Zero, the government increased the funding you can receive for applying.

Under this new amendment, homeowners can receive as much as £7,500 for air and ground heat pump installations. Eligible property owners who opt for biomass boilers will still get £5,000.

Boiler Upgrade Scheme Eligibility

Are you wondering about your grant eligibility? Below are the requirements you and your property should meet to qualify:

Property Address

The first qualification is your property’s address. This initiative targets homeowners in Wales and England, so your home or non-domestic building must be in those areas.

You must also legally own the property you’re applying for. This rule applies to homes, second homes, business buildings, or rental properties.

Property Heating System

The second requirement is your current heating system. Only properties powered with fossil fuel systems like oil, gas, and electricity are eligible for the grant.

Additionally, the Boiler Upgrade Scheme officially opened in April 2022. So, only those who installed or were planning to install a new heating system after the said date qualify.

Property Requirement

Lastly, your home must have a 45kWth installation capacity. The programme also requires submitting a valid Energy Performance Certificate showing your property’s energy efficiency.

Moreover, your home or non-domestic building mustn’t have an outstanding insulation installation recommendation. That said, your property still qualifies even if you recently received funding for energy efficiency grants, like the Great British Insulation Scheme.

Properties Ineligible for the Grant

Newly built homes and buildings don’t qualify under the scheme. So, if your property is still in construction, you won’t be able to apply for boiler funding.

However, you may apply for the grant if you move into a newly built home or building with a fossil fuel heat source already installed.

Self-build houses are also generally ineligible for the Boiler Upgrade Scheme. Social housing and properties already given funding for heat pump cost support don’t qualify as well.

If you have a self-build building, you can apply for the grant if you or the previous owner built or paid builders to make the property. But the building shouldn’t have a history of businesses or organisations owning it, and you must show proof that your home is a self-build.

How to Apply for the Boiler Upgrade Scheme

The BUS scheme is an installer-led initiative. It means that the heat pump installers will apply to the scheme on behalf of the homeowners.

So, what should you do? Here’s a breakdown of the steps you need to follow to enjoy the benefits of the Boiler Upgrade initiative:

Step 1: Find an Installer

First, you’ll need to contact an MCS-certified installer in your area. We can help you with this and put you in contact with one of our expert installers who’ll assess your property and provide a quote for the work.

Step 2: Confirm Your Eligibility

After the assessment, the MCS-certified installer will confirm your eligibility for the Boiler Upgrade Scheme. The installer will then present a quote for the overall cost of the boiler installation.

You may wish to get a quote from at least two or three installers to ensure you get the most out of the boiler upgrade initiative. This step will help you gauge whether you’re getting a fair price for the services you need.

Step 3: Apply for Scheme

Once you agree with the quote, your MCS-certified installer will apply for the grant in your place. They’ll submit the necessary documents to the Ofgem website, including their company, MCS, and personal details.

Step 4: Verify with Ofgem

After the application, Ofgem will contact you to verify the installer’s identity and confirm they’re working on your behalf. Ofgem might contact your phone and visit your property to check your property’s eligibility for the grant.

Should You Upgrade to a Low-Carbon Heating System?

Your household’s heating system is responsible for a significant portion of your annual energy costs. This fact stresses the importance of efficient heating systems for cutting your bills.

Low-carbon heating is an excellent and affordable alternative to fossil fuel boilers. They’re more efficient in consuming energy, keeping your home warm and toasty without the extra costs associated with traditional heating systems.

Another fantastic benefit of switching to low-carbon heating systems is reduced carbon emissions. It means your household won’t be emitting as much carbon dioxide, which helps reduce the impact of climate change.

Frequently Asked Questions

Still curious about the Boiler Upgrade Scheme? Here are a few commonly asked questions to help with your enquiries:

What is the Net Zero 2050?

The UK’s Boiler Upgrade Scheme falls under the Net Zero 2050 initiative. It’s an environmental report from the International Energy Agency (IEA) detailing the policies and behavioural changes needed to achieve a net zero energy system within three decades.

How Long Will the Boiler Upgrade Scheme Last?

The Boiler Upgrade Scheme will run for seven years, from its launch in 2022 until 2028. The first three years (2022 to 2025) will draw from a budget of £450 million, dedicated to assisting homeowners transitioning to low-carbon heating systems.

Is the Boiler Upgrade Scheme Available for Ireland and Scotland?

Unfortunately, the Boiler Upgrade Scheme only applies to individuals living in England and Wales. But there are initiatives you can access if you’re living in these countries.

For Scotland, they offer an interest-free loan for projects improving energy efficiency. In Northern Ireland, you may contact NI Energy Advice for available grants.

Can You Replace an Existing Low-Carbon Heating System?

No, the Boiler Upgrade Scheme doesn’t give funds for replacing existing low-carbon boilers. Only households with existing fossil fuel heating systems are eligible.

So, if you have a ground source heat pump installed, you won’t be able to apply for the grant. This policy extends to existing biomass boilers and air-source heat pumps.


We’ve all witnessed energy prices soaring sky-high in recent years. As such, many of us are looking for cheaper and eco-friendly alternatives for household heating systems.

The Boiler Upgrade Scheme is an excellent opportunity to transition to energy-efficient, low-carbon heating systems. It’s a valuable initiative for those who prefer a greener, cleaner, and cost-effective way to warm their homes.
