Every home's heat charge, and a letter explaining it

Upload your list of homes and last year's costs. Heatdesk shares them the way Ofgem's cost allocation guidance describes, shows the working, and writes each home a letter. Ofgem sets no price, so this shows how you got to a charge. It doesn't say the charge is fair.

How are the costs shared between homes?

Metered: each home's kWhFuel by each home's kWh, fixed costs equally. Ofgem expects accurate readings to be used where meters exist.Unmetered: by floor areaOfgem suggests floor area or bedrooms in place of meters, with the same standing charge per home.Unmetered: by number of bedroomsOfgem suggests floor area or bedrooms in place of meters, with the same standing charge per home.Fixed shares in the leaseIf the lease fixes each home's share, you use it. The working sets it beside Ofgem's approach.
