How we worked this out
What this does not tell you
It is a typical bill for a home of your kind, not a reading of your meters. It assumes you pay by direct debit at the price cap, so a fixed deal, prepayment meter or other tariff will differ. Households vary a great deal around a typical home: how many people live there, when they are in and how warm they keep it all matter, and none of that is asked here. Solar panels, an electric car and a home business are not included. Costs for improvements are typical, not quotes, and before any grant.
