Gas boiler running cost

Estimates the annual cost of running a gas boiler for heating and hot water, using the maximum a supplier may lawfully charge per unit under Ofgem's domestic price cap. It is not a price, a bill, or an estimate of what you will actually pay — what you pay depends on your own tariff and supplier.

Covers Great Britain (England, Scotland and Wales) only — it does not cover Northern Ireland, which has separate arrangements.
