The United Kingdom


Member Country Report, Market Overview, The United Kingdom – September 7, 2021. 
The Member Country Report of the United Kingdom included a market overview, and the UK delegate discussed the overall background of the UK’s energy system, a market overview of heat pumps, some of the strategic policies that interact with heat pumps, and the development of innovative programs. In total, there are 26.2 million households in the United Kingdom, with 22 million of those being served by main gas. Heat pumps are now a small market in the UK for residential buildings, although they are commonly employed in commercial buildings. Despite the introduction of the Renewable Heat Incentive Intervention in 2014, the present domestic market for heat pumps sales has remained largely stable; however, sales have begun to increase as the new policy clarity emerges and consumer knowledge grows. The majority of market growth is in air-water monobloc systems, which have fewer installation restrictions. According to the delegate, around 300,000 heat pumps are presently installed in homes, while gas boiler sales are approximately 1.6 million units each year. High-level policies include the clean growth strategy 2017, clean growth transforming heat 2018, the government’s 10-point plan energy white paper 2020, which aims to install 600,000 heat pumps per year by 2028, as well as the renewable heat incentive (RHI) and the clean heat grant, which will be the RHI’s successor. The adaptability of the building stock, customer knowledge, the gas/electricity pricing ratio, and the upfront cost of systems remain significant impediments.  Download the presentation here.
