Overview
- A Censuswide poll of 1,000 owners, commissioned by the Green Britain Foundation, reports 66% find heat pumps cost more to run than their previous systems, citing electricity priced about four times higher per kWh than gas despite efficiency gains.
- Ministers point to Department for Energy Security and Net Zero research showing 89% satisfaction after a winter of use, with respondents most commonly reporting bill reductions and potential savings with time‑of‑use tariffs.
- The government has added £2.7 billion to heat pump subsidies alongside grants of up to £7,500 within the £15 billion Warm Homes plan, which includes low or zero‑interest loans and free upgrades for lower‑income households.
- Adoption is growing, with about 98,000 units sold in 2024, up 64% year on year, though a Resolution Foundation analysis finds uptake concentrated among richer households.
- Outcomes vary widely, with one London homeowner reporting bills falling from roughly £160 to £40 a month by pairing a heat pump with rooftop solar and an off‑peak electricity tariff.
