The number of heat pump installations in the UK is the key measure of the country’s heating transition
For any homeowner considering a low-carbon heating system, the single most important fact is the official installation figure for the most recent full year. Published data from the government’s Microgeneration Certification Scheme (MCS) and the Department for Energy Security and Net Zero (DESNZ) provides the definitive count. This number tells you how quickly the market is moving and whether the government’s heat pump targets are being met. The figure is the baseline for understanding your own installation options and potential future demand.
83,000 heat pumps were installed in the UK in 2025, a 38% increase from 60,000 in 2024. This official MCS figure shows accelerating adoption but remains well below the government's 2028 target of 600,000 per year.
- 83,000 MCS-certified heat pumps installed in the UK in 2025.

The official MCS installation figure for 2025
The MCS Data Dashboard records the total number of accredited heat pump installations in the UK for the calendar year 2025. The headline figure is the total number of heat pumps (air source, ground source, and water source) installed by MCS-certified installers. According to the MCS Data Dashboard, the total number of MCS-certified heat pump installations in the UK during 2025 was 83,000 (MCS Data Dashboard, 2026). This figure is the primary data point cited by the government and industry bodies like the Heat Pump Association (HPA).
How the 2025 figure compares to the previous year’s total
The year-on-year change is the most useful comparison for understanding market momentum. The official 2024 total from the same MCS and DESNZ sources was 60,000 installations. The 2025 figure of 83,000 is a 38% increase year-on-year. This comparison shows that the Boiler Upgrade Scheme and other policies are accelerating adoption, though the total remains well below the government’s target of 600,000 installations per year by 2028 (DESNZ, 2026).
The Boiler Upgrade Scheme’s contribution to the 2025 total
The Boiler Upgrade Scheme (BUS) provides a £7,500 grant (as of 2025) towards the cost of a heat pump. The number of BUS vouchers redeemed in 2025 is a subset of the total MCS installations. Ofgem’s official statistics show that 32,000 BUS vouchers were redeemed in 2025, meaning that roughly 39% of all 2025 heat pump installations were supported by the grant (Ofgem, 2026). This figure shows how government subsidy is driving a significant portion of the market, though the majority of installations (61%) were funded privately.

What the 2025 installation figure means for your home
The 83,000 installations in 2025 tell you that heat pumps are a mainstream, growing technology in the UK, not a niche product. It indicates that a growing network of MCS-certified installers is available to quote for your property. The 38% increase compared to 2024 shows that the market is scaling, which can influence future pricing and installer availability, greater demand typically leads to more competition and potentially lower prices over time.

How to verify an installer and check their 2025 installation record
To ensure your installation is counted in future official data, you must use an MCS-certified installer. The MCS Installer Database lets you search for local installers and view their certification status (MCS Installer Database, 2026). TrustMark is a complementary quality mark for home improvement work, often required alongside MCS for certain grants (TrustMark, 2026). Gas Safe Register is NOT relevant for heat pumps; the correct certification is MCS for the product and NICEIC or NAPIT for the electrical connection (NICEIC, 2026).

Frequently Asked Questions
83,000 heat pumps were installed in the UK in 2025, according to the MCS Data Dashboard. This is the official figure cited by the Department for Energy Security and Net Zero (DESNZ).
The 2025 figure of 83,000 is a 38% increase from 60,000 installations in 2024, as recorded by the MCS and DESNZ. This shows accelerating adoption but still well below the 2028 target.
The Boiler Upgrade Scheme (BUS) was a key driver, offering a £7,500 grant (as of 2025) towards heat pump costs. The number of BUS vouchers redeemed in 2025 contributed significantly to the total MCS figure.
The Boiler Upgrade Scheme (BUS) redeemed a significant portion of the 83,000 total. Exact BUS figures for 2025 are published by DESNZ, but the scheme directly supported the year-on-year growth.
The UK government target is 600,000 heat pump installations per year by 2028, as set by DESNZ. The 2025 figure of 83,000 shows the market is still far from this goal.
