The UK heat pump market continues to gather pace, with installation numbers rising steadily as homeowners look for low‑carbon alternatives to traditional gas heating. This growth is being driven largely by government incentives, changing energy priorities, and a broader push toward net zero.

Rapid growth in UK heat pump installations

Recent figures show that the UK has now supported more than 180,000 heat pump installations through government-backed schemes since 2018. Adoption is accelerating, with installation numbers increasing year on year, particularly since 2024, highlighting a growing shift away from fossil-fuel heating systems.

Air source heat pumps account for the vast majority of installations, making up around 98% of systems installed with subsidy support in the most recent reporting period. This reflects the relative simplicity and suitability of air source systems for many UK properties.

Government driving demand through grants

A key factor behind this growth is the Boiler Upgrade Scheme (BUS), which currently offers grants of up to £7,500 to help cover the cost of installing a heat pump. These grants significantly reduce the upfront investment required and have made heat pumps more accessible to homeowners and businesses alike.

Other support mechanisms, such as the Energy Company Obligation (ECO) scheme, have also contributed to installation figures, although changes to funding structures mean the BUS is expected to become the main source of support going forward.

What this means for homeowners

While increasing installation numbers are positive for the UK’s transition to cleaner energy, they also bring new considerations for homeowners. More heat pumps in operation means a greater need for ongoing maintenance, servicing, and occasional repair.

As the market expands, not every installation will perform perfectly over time. Factors such as system design, property suitability, and installation quality all play a role in long-term performance. As a result, reliable aftercare and specialist repair services are becoming an essential part of the wider heat pump ecosystem.

The growing importance of support and repair

With hundreds of thousands of systems already installed and many more expected in the coming years, the demand for experienced heat pump engineers is only set to rise. Homeowners increasingly need access to professionals who understand how to diagnose issues, optimise performance, and keep systems running efficiently.

For businesses like Renserv, this rapid growth represents both an opportunity and a responsibility: to support homeowners as they transition to low‑carbon heating, and to ensure those systems continue to operate as intended long after installation.
