What are the heat source heat pump trends for 2026? The landscape for air-source heat pumps (ASHPs) in the UK is evolving quickly. Installations continue rising, new technology and policy developments are shaping the market, and public interest remains high. Here are some of the most important trends to watch, and why they matter for Greater London homeowners thinking about making the switch.
Rising Installations and Growing Market Confidence
The past couple of years have seen a surge in heat pump installations across the UK. 2024 set a record for certified heat pump installs, with the number of installations drastically exceeding previous years. In early 2025 the trend held strong. For example, in January 2025 there were nearly 5,000 heat pump installations, a 21% increase over the same month in 2024.
This rising installation rate shows growing consumer confidence in ASHP technology. More households are choosing low-carbon, efficient heating at a time when energy bills and environmental concerns are front of mind.
Government Support Remains Crucial
Government support has played a key role in driving uptake. The grant offered under the Boiler Upgrade Scheme (BUS) has helped make heat pump installations more affordable, reducing upfront costs for homeowners.
Shifting Awareness, Public Perception, and Demand Patterns
Public awareness of ASHPs remains high. A 2025 survey by the government department responsible for energy found that around 76% of respondents recognised air source heat pumps, a modest drop from earlier in the year but still well above pre-campaign levels.
Knowledge (meaning a deeper understanding of how they work, cost savings, and suitability) remains lower, which suggests many potential adopters remain undecided or still need more information.
For 2026, clear, localised advice and guidance, especially from trusted local providers such as Harvard Renewables, can help turn interest into energy-efficient heating for homes.
What 2026 Means for Homeowners Considering a Switch
If you are considering a heat pump for your home in 2026, the climate is favourable. The market is growing, technology is improving, and government support remains available.
However it pays to act soon: as demand rises, installer availability could tighten, supply-chain pressure might increase, and grant demand may intensify.
For people with older boilers or inefficient heating, switching now could mean long-term savings, higher efficiency, and lower carbon emissions. For those building or renovating homes, there is likely to be even more choice throughout 2026.
