Space heaters

Heating your home needn’t cost the earth. To help you calculate running costs and choose the best energy-efficient appliances, use the star ratings system.

Look for the Energy Rating Label, displayed on all new electrical appliances, to calculate running costs and find the most efficient heating for your needs.

Compare models with the same star ratings by looking at the energy consumption specification on the label. The lower the consumption, the less it will cost to run the heater.

Over the lifetime of an appliance, the running costs can often exceed the purchase price of some appliances, so before you buy use the Energy Rating Calculator to compare how much different models are likely to cost in the long run.
