The Boiler Upgrade Scheme 2026 is still a big chunk of the UK’s clean heating plans. The UK Government has said it’s backing low-carbon heating technologies quite firmly. The Boiler Upgrade Scheme is meant to help property owners switch away from a fossil fuel heating setup.
Nowadays, many householders are interested in the heat pumps as they can reduce emissions and future-proof the house. The budget of the scheme for 2026 has been allocated at £400 million. That builds on earlier funding promises, including £295 million that was set aside in older years.
The funding supports households in England and Wales that want to upgrade their existing heating system. It’s essentially designed to make the early costs less daunting.
What Is the Boiler Upgrade Scheme?
The United Kingdom Boiler Upgrade Scheme was launched back in May 2022 and was initiated by the Department for Energy Security and Net Zero. The main goal of this initiative is encouraging households to replace fossil fuel boilers. It does this by supporting the installation of a low-carbon heating system, rather than just talking about it.
The eligible technologies generally include air-to-water heat pumps, a ground source heat pump, and a biomass boiler. The programme also supports people who want to replace older systems like a gas boiler , oil boiler, LPG setup, or other types of fossil fuel heating.
The scheme concentrates on the low-carbon technologies that ensure space heating and the production of hot water. The scheme has undergone some changes since its launch, and this is why some applicants may experience differences compared to the first round.

Boiler Upgrade Scheme Budget for 2026
The UK Boiler Upgrade Scheme for 2026 will have a budget of £400 million. The money will cover the period starting from April 2026, and the government will offer additional funding till March 2027. The generous budgeting means the growing popularity of heat pumps and biomass boilers among homeowners.
The budget is trying to nudge adoption of renewable heat technologies. It also backs up national energy security goals, kind of in the same breath. That ongoing investment is, honestly, a signal of trust in cleaner heating solutions. A lot of industry experts think demand will stay pretty steady all through 2026 and then 2027.
What Technologies Are Supported?
People applying may be able to get help for a heat pump or a biomass boiler, depending on eligibility. The most popular option is the air source heat pump. It utilizes heat that is available in the outdoor air regardless of weather conditions. Ground source heat pump is another efficient solution to provide hot water and heating. Some properties may benefit from water source heat pumps.
A biomass boiler may qualify where specific requirements are met. The scheme also recognises emerging technologies such as a heat battery. However, an air-to-air heat pump is generally not supported through the current scheme. Property owners should confirm technology requirements before applying.
Who Is Eligible?
Eligibility requirements apply to every application. A homeowner must own the property being upgraded. Some landlords can also participate. The property must be located in England or Wales. Applicants must meet current eligibility requirements for boiler upgrade scheme. Most homes require a valid Energy Performance Certificate.
The property’s energy performance information helps determine suitability. Recommended improvements may include loft or cavity wall insulation. Good insulation makes the new heating setup work better, without much fuss. Before anything, applicants should read every scheme rule, properly. Otherwise it gets messy later.
What Heating Systems Can Be Replaced?
The scheme supports households switching from fossil fuel heating. Many applicants replace a gas boiler. Others may replace an oil boiler or LPG system. Some properties replace an older electric heating system.
The goal is to move households towards cleaner technologies. A modern heat pump can reduce dependence on traditional fuels. Many homes located away from the gas grid may benefit significantly.
How Does the Application Process Work?
The programme uses an installer-led approach. This means homeowners do not usually submit the application directly. An approved installer completes the application process. The installer can submit an application on your behalf.
After approval, a grant voucher is issued. The value of the voucher is deducted from the installation price. This helps reduce the upfront cost for applicants. The process is overseen by Ofgem.
Why Is an MCS-Certified Installer Required?
Every installation must be completed by an MCS-certified installer. You may also see this written as MCS certified. MCS stands for the Microgeneration Certification Scheme. The scheme ensures quality and performance standards.
Using an MCS-certified professional is mandatory. An approved installer must meet recognised industry requirements. This protects consumers and supports installation quality.
Heat Pump Installation and Running Costs
The cost of installing a heat pump varies. Property size and existing infrastructure affect pricing. An air source heat pump is often less expensive than a ground source heat pump. The ground source heat system usually requires more groundwork.
However, many households benefit from lower running costs over time. A properly designed heat pump installation can improve efficiency. This is especially true when paired with strong insulation measures.
Heat Pump or Biomass Boiler?
Many households compare a heat pump or biomass system. Others ask whether a heat pump or biomass boiler is better. The answer depends on the property and heating needs. A source heat pump generally offers excellent efficiency.
Ground source heat pump offers reliable performance throughout the year. Biomass boiler is considered a good option in the countryside. Consulting an expert helps to make a better choice of technologies.
Key Dates to Remember
The first funding period for the Boiler Upgrade Scheme ran from May 2022 to December 2025. The next period with more generous budget will begin from April 2026. Updates of the program can be expected in February 2026 and July 2026.
Applicants should pay attention to news about this scheme, as the regulations might change. The current funding period lasts until March 2027.
Where Can Homeowners Find Guidance?
Property owners can seek advice from the Energy Saving Trust. Scottish residents may find information through Home Energy Scotland. Even though Scotland has a parallel scheme, the Boiler Upgrade Scheme is for England and Wales. So applicants should always verify the latest guidance. Requirements can change, over time , without much warning.
Final Thoughts
Thus, the Boiler Upgrade Scheme budget 2026 is estimated at £400 million. This fact proves that the government continues providing financial support. This is one of the schemes that allow property owners to replace their fossil fuel boiler with a new, environmentally friendly system. Property owners who meet all criteria can benefit from the Boiler Upgrade Scheme installer.
Whether you’re leaning toward an air source heat pump, a ground source heat pump, or a biomass boiler, the funding can help cut the upfront cost. For many households, swapping out a fossil fuel heating system can bring longer-term advantages too. The scheme supports cleaner energy, improved efficiency, and greater use of renewable heat across England and Wales.
