When it comes to heating your home in London, the boiler is at the heart of it all. While gas boilers remain the most common, electric boilers are becoming more popular as technology improves and energy regulations tighten. So which one is right for your home? Let’s compare the two.
Gas Boilers
Gas boilers use natural gas supplied by the mains. They’re familiar, efficient, and widely installed across the UK.
Pros:
-
Generally cheaper to run than electric boilers, thanks to lower gas prices.
-
A wide range of models and sizes.
-
Ideal for larger households needing lots of hot water.
Cons:
-
Requires a gas supply (not available in all properties).
-
Produces carbon emissions.
-
Needs annual Gas Safe servicing.
Electric Boilers
Electric boilers run entirely on electricity, heating water directly.
Pros:
-
Compact and easy to install – no flue needed.
-
Zero emissions at the point of use.
-
Very quiet operation.
-
Ideal for flats, small homes, and off-gas properties.
Cons:
-
Electricity is currently more expensive than gas per unit.
-
Less suitable for homes with high hot-water demand.
-
Power cuts mean no heating.
London Considerations
-
Flat living: electric boilers can be easier in flats with no outside flue access.
-
Green energy: pairing electric boilers with renewable tariffs can cut your carbon footprint.
-
Cost: gas is still cheaper for most Londoners, though prices fluctuate.
Final Thoughts
Gas remains the go-to for most larger homes, but electric boilers are an increasingly practical option for smaller London flats and eco-minded households. The right choice depends on your property, budget, and priorities.
