A method of providing heat to a user, comprises an energy retailer offering to supply energy over a contract period at a given amount of energy per use period. The use period may be weekly, monthly, quarterly, six-monthly or annually. The cost of energy supply to a user increases if they use more than the given amount. A boiler, fitting the boiler and servicing of a users heating system may be provided as part of the contract. Promotions may be offered by a retailer which may be offset against fuel used. A subsidy of cost may also offered. Some users may offer to pay a premium so as to place money in a subsidy fund for the use of others and the subsidy fund may receive money from and distribute subsidies to users in a geographical area defined by town, village or a plurality of post codes. The energy retailer may be an intermediary (i.e. may buy gas from others to resell).
