This is an estimate, not a quote. Price cap rates change every three months and differ by region, so a cap-based figure assumes today's GB average rates stay the same for the whole period. Check your own regional rates on your bill or Ofgem's regional table.

This calculator needs JavaScript. You can still work it out by hand: for each fuel, multiply your yearly kWh by the unit rate, add 365 times the daily standing charge, and divide by 100 to get pounds.
