Figures are based on the October 2025 Ofgem electricity price cap of 26.35p per kWh and an average household consumption of 4,500 kWh per year. Savings are modelled on a south-facing roof with approximately 70% self-consumption and an export rate of £0.15 per kWh. Actual savings will vary depending on system size, household usage, roof orientation, shading, and energy tariff. These examples are for illustration only and are not guaranteed.

The figures shown on the ASHP page are estimates for illustrative purposes only and reflect UK domestic typical unit rates and system efficiencies as of Q4 2025 (e.g., electricity ~26.35p/kWh; gas ~6.29p/kWh) under the Ofgem price cap. Rates vary by region, supplier, tariff type, payment method and usage profile. System efficiency is influenced by age, maintenance, installation quality and actual operating conditions. Use of this table should be accompanied by a statement that actual costs and savings will differ, and homeowners should obtain a tailored quote and review their tariff, usage and system condition for accurate budgeting.
