Comfy Heat is a two rate central heating domestic tariff, which provides eight hours of cheaper electricity.

The electricity units are currently charged at 22 pence per unit (peak rate) during the hours of  06:00 to 14:00 and 16:00 to 00:00 Greenwich Mean Time (GMT) and 9.6 pence per unit (off-peak rate) during the hours of 00:00 to 06:00 and 14:00 to 16:00 GMT.  Off-peak hours will advance during British Summer Time (BST).

During the off-peak switching times all units used, including those used for heating, will be charged at the cheaper rate. Therefore you can benefit from using timer switches on a range of appliances to use them during the cheaper hours, such as a washing machine, tumble dryer or dishwasher. Your fixed heating load may be separately wired and may also be switched on by the electricity meter.  You are responsible to ensure that your electricity supply switches at the appropriate time by carrying out regular checks of the switching times of the meter.  If you have any concerns you should contact our customer service team immediately on 687675.

No, properties built of stone, that have high ceilings, are single glazed or have no or minimal insulation will not be suitable for Comfy Heat.
