In 2025, the UK installed over 125,000 air source heat pumps, a 27 percent increase on the previous year. This growth shows a clear shift towards low-carbon heating solutions in homes and businesses across London and the South East. But what is driving the rise in air source heat pump installations? We take a look at in our latest blog.
Global Energy Trends Are Driving Interest
Rising energy costs are a key factor in the surge of interest. Volatility in international markets, including higher oil prices linked to tensions in the Middle East, has highlighted the importance of installing resilient heating systems for homeowners.
Government Support and Policy
Schemes like the Boiler Upgrade Scheme and the UK’s net zero targets demonstrate that low-carbon heating is a national priority. These incentives are making air source heat pumps a practical choice for homeowners and property developers, encouraging wider adoption.
Industry Growth and Confidence
Around 36 percent of heat pumps sold in 2025 were manufactured in the UK, supporting local jobs and creating a more robust supply chain. A growing number of certified installers also gives homeowners confidence in system performance, helping to reach the government’s aim to install 450,000 heat pumps per year by 2030.
The Future of Home Heating in London and the South East
Air source heat pumps are no longer a niche solution. Their growth reflects a combination of long-term trends rather than short-term hype. Rising global energy costs and volatility in oil and gas markets have prompted homeowners and developers to consider heating systems that are more resilient to price fluctuations.
Government incentives and the push toward net zero have created a regulatory environment that encourages low-carbon heating solutions.
Technological improvements have also played a role. Modern air source heat pumps are more efficient, quieter, and easier to integrate into a variety of properties, including older homes and urban builds.
Taken together, these factors explain why heat pumps are moving from early adoption into the mainstream. They are not just a response to environmental goals; they are part of a strategic approach to energy security and long-term home planning, especially for homeowners in London and the South East who are facing high energy costs and planning for a low-carbon future.
