Exploring the UK Boiler Upgrade Scheme: Your Path to Energy Efficiency

Embark on a journey towards energy efficiency and a greener future with the Boiler Upgrade Scheme. Say goodbye to the high costs of replacing your old boiler—this UK grant offers a fantastic opportunity to upgrade without breaking the bank. Alongside the Energy Company Obligation (ECO4), it stands as a cornerstone in the UK government's strategy for achieving total home decarbonisation by 2050.
In our comprehensive guide, we delve into the details of the Boiler Upgrade Scheme. Explore the financial support available for each installation, the eligibility criteria, and a step-by-step application process.
Maximise Savings with the Boiler Upgrade Scheme: Available Fundings
The Boiler Upgrade Scheme (BUS) offers a generous £3.9 billion in funding to assist homeowners in upgrading to energy-efficient heating systems. This grant provides substantial financial support for three heating system options: biomass boilers, air-source heat pumps, and ground-source heat pumps.
Exciting updates to the Boiler Upgrade Scheme (BUS) funding have made upgrading to energy-efficient heating systems even more appealing and affordable. Effective from 23 September 2023, biomass boilers now qualify for £5,000 in funding; while air-source and ground-source heat pumps enjoy a substantial increase to £7,500 each, up from £5,000 and £6,000 respectively.

Consider the cost implications: Installing an air-source heat pump, including installation, usually costs around £12,000. However, with the Boiler Upgrade Scheme, eligible homeowners only need to pay £4,500. This means the scheme covers approximately 62% of the total installation cost, resulting in significant savings. For ground-source heat pumps, which have an average cost of around £20,000, the scheme covers 37% of the cost. Similarly, for biomass boilers, which typically cost around £16,000, the scheme covers 31%.
Heating System | Average Cost of Installation | Funding Provided by Boiler Upgrade Scheme | Percentage Savings |
---|---|---|---|
Air-Source Heat Pumps | £12,000 | £7,500 | Approximately 62.5% |
Ground-Source Heat Pumps | £20,000 | £7,500 | Approximately 37.5% |
Biomass Boilers | £16,000 | £5,000 | Approximately 31.25% |
Eligibility Criteria for the Boiler Upgrade Scheme
The Boiler Upgrade Scheme (BUS) is a fantastic opportunity for homeowners in England and Wales to upgrade to more energy-efficient heating systems. While the Boiler Upgrade Scheme caters exclusively to residents of England and Wales, Scotland offers its own array of grants, including the Warmer Homes Scotland and Home Energy Scotland schemes.
To ensure you can take advantage of this scheme, it's essential to understand the eligibility criteria. Here, we outline the specific requirements you must fulfil to qualify for the Boiler Upgrade Scheme:

FAQs
Quick, Essential Answers
A 20-year-old boiler is typically much less efficient than modern models. Older boilers often have efficiency ratings of around 60-70%, meaning they waste 30-40% of the energy they consume. In contrast, modern boilers can achieve efficiency ratings of 90% or higher, significantly reducing energy waste. Heat pumps, with efficiencies of 400%, offer even greater efficiency gains.
