The Boiler Upgrade Scheme: A Step Towards Cleaner, Greener Heating

As the UK moves toward a more sustainable future, the way we heat our homes and businesses is changing. Traditional gas and oil boilers are being phased out in favour of low-carbon, renewable alternatives – and the Boiler Upgrade Scheme (BUS) is helping to make that transition possible.

This government-backed initiative aims to support households and small businesses across England and Wales in replacing fossil fuel systems with energy-efficient, low-carbon heating technologies such as air source and ground source heat pumps, and in some cases, biomass boilers.

What Is the BUS Scheme?

The Boiler Upgrade Scheme (BUS) is a key part of the UK’s wider decarbonisation strategy. It provides upfront capital grants to help cover the cost of installing renewable heating systems, making them more affordable and accessible.

Instead of leaving homeowners to navigate complex funding processes, the scheme allows installers to apply on behalf of property owners. The grant is then paid directly to the installer, reducing the upfront financial burden on customers and simplifying the switch to renewable heating.

The BUS currently offers:

£7,500 towards the installation of an air source or ground source heat pump.

New changes for 2026

In early 2026, the UK’s Boiler Upgrade Scheme (BUS) will undergo several updates. Air-to-air heat pumps will become eligible for a £2,500 grant; hybrid systems will gain greater flexibility – allowing them to be installed alongside other electric appliances.

Once standards are in place, homeowners can also receive a £2,500 grant for a heat battery, which stores electricity for heating and hot water, often generated when energy prices are lower. This change supports flexible, low-cost heating and helps households further reduce reliance on fossil fuels.

Making the Heat Pump Journey Simpler
From Year 5 of the scheme (2026/27), EPC requirements are expected to be eased. This will streamline the process and remove unnecessary administrative barriers for homeowners looking to switch to a heat pump.
Introducing Support for Heat Batteries
Heat batteries – designed to store energy for space heating and hot water – are set to become eligible for a £2,500 grant once the necessary standards are finalised.
Better Access to Third-Party Ownership Models
The government plans to expand and clarify third-party ownership options, paving the way for more flexible finance solutions such as leasing and service-based agreements.
Enhanced Consumer Protections
Updates to the MCS Customer Commitment are being considered to reinforce installation quality and strengthen consumer confidence across the sector.

Why It Matters

Heating is the largest source of carbon emissions in the UK, contributing to nearly a third of the country’s greenhouse gas emissions. The UK government has set a target to reduce annual greenhouse gas emissions by at least 80% by 2050. Switching to renewable heating cuts your carbon footprint and is designed to reduce overall energy demand, so today you can support the change.

Here are some of the key benefits:

Lower carbon footprint – Cut emissions by up to 80% compared to gas or oil boilers.
Reduced energy bills – Modern heat pumps are highly efficient, using less energy to deliver the same comfort.
Future-ready homes – Upgrading now helps properties meet net-zero targets and future energy standards.
Improved air quality – Biomass and electric systems produce fewer pollutants than fossil fuels.

Who Can Apply?

The scheme is open to homeowners, community owned properties, and businesses located in England and Wales.

To qualify, you must:

Have a valid Energy Performance Certificate (EPC)
Be replacing a fossil fuelled heating system
Use an MCS registered installer

Building a Sustainable Future

The Boiler Upgrade Scheme is more than just a funding programme – it’s a crucial step on the UK’s journey to net zero. By helping property owners adopt renewable heating technologies, the scheme is reducing reliance on fossil fuels, cutting emissions, and promoting long-term sustainability across the built environment.

Now is the ideal time to take advantage of the Boiler Upgrade Scheme grant and join thousands of households already benefiting from renewable, efficient, and future-ready heating.

So, why not apply for the Boiler Upgrade Scheme today and start your journey towards a cleaner, greener home?
