Is it cheaper to run an electric boiler or a gas boiler?

In most UK homes, a gas boiler is usually cheaper to run than a direct electric boiler because gas normally costs less per unit of energy than electricity. Electric boilers are very efficient at the point of use, but the higher price of electricity often makes the total running cost higher.

A gas boiler may waste some heat through the flue, but the lower fuel cost can still make it cheaper overall. This is why gas boilers are still commonly used in larger homes or properties with higher heating demand.

However, the best option depends on the building. Electric boilers can make sense in small, well-insulated homes, flats, occasional-use buildings, extensions, offices, or properties without a gas supply. They may also be easier and cheaper to install because they do not need a flue, gas pipe, oil tank, or fuel storage.

For larger or poorly insulated homes, gas boilers or heat pumps are often cheaper to run. The correct choice depends on insulation, heating demand, electricity tariff, hot water usage, and installation cost.
