UK Heat Pump Firms Warn of Subsidy Cuts

Heat pump installation companies across the United Kingdom are preparing for a reduction in government funding as the Treasury seeks savings ahead of the budget scheduled for Wednesday. The proposed cuts target the Boiler Upgrade Scheme, a subsidy that currently supports the transition away from fossil fuel heating.

Bill Tuck, operations director at Sustain Homes in Watford, stated that approximately 75% of his clients depend on the government grant to cover the cost of their systems. Tuck described the subsidy as the foundation of his business and expressed uncertainty regarding the company's ability to retain staff if the financial support disappears.

The scheme was launched in 2022 to assist homeowners in reducing emissions. It provides upfront payments of up to £9,000 for those replacing old heating systems with low-carbon alternatives such as heat pumps and biomass boilers. While the Department for Energy Security and Net Zero has labeled the current decade a critical period for decarbonizing heat, UK installation rates remain low compared to other European nations.

Data from the government indicates that building heating contributes nearly a fifth of the country's greenhouse gas emissions. Norway, currently the global leader in adoption, has 632 heat pumps per 1,000 households, a figure far exceeding the UK's rate of 3.5 per 1,000 households.

Industry figures point to past subsidy changes as a warning for current operations. Adam Killa, founder of Ask Renewables in Burscough, Lancashire, reported that his weekly installation volume dropped from eight to zero after the Renewable Heat Incentive ended in 2022. Customers cited the ability to purchase a standard boiler for £3,000 instead of paying £15,000 for a heat pump.

Jim Lacey of JLN Plumbing & Heating in the UK has installed renewable systems for 20 years. He noted that the argument regarding long-term savings on running costs is losing traction as upfront prices remain high. Lacey described a sudden withdrawal of support as catastrophic for the trade, affecting not just installers but also manufacturers and delivery companies. He added that about a third of heat pumps sold in the UK in 2024 were produced domestically, according to the Heat Pump Association.

A government spokesperson declined to comment on budget speculation. The official stated that the government remains committed to lowering household bills while investing in domestic clean energy to protect consumers from fluctuating fossil fuel prices.
