Electric boiler installation for flats, homes & outbuildings

A good electric boiler installation starts with the property, not the boiler box. We assess heat demand, available electrical capacity, hot-water requirements, existing radiators or underfloor heating, controls and the practical route for new circuits before recommending a system.

Important: boiler kW output and cable/protective-device requirements must be based on the actual installation and current manufacturer instructions. We do not size high-load electric boilers from bedroom count alone.

Why flats and London properties are a strong fit

Electric boilers are frequently considered where there is no individual gas connection, a flue route is impractical, the plant space is compact or a landlord wants an all-electric refurbishment. The trade-off is electrical demand, so the incoming supply and hot-water expectations must be checked early.

Frequently asked questions

Are electric boilers suitable for flats?

Often, yes. Flats are one of the strongest use cases because electric boilers need no combustion flue. The electrical supply, heat demand and hot-water expectations still need to be checked before choosing the output.

Do I need three-phase power?

Not always. Many domestic systems are available for single-phase supplies, but larger outputs can require three-phase. We assess supply capacity before specifying equipment.

Can an electric boiler run radiators?

Yes. Electric flow, system and combi boilers can serve wet radiators and many can work with underfloor heating when designed and controlled correctly.

Can you install the electrical circuit as well?

Yes. Electrical supply design and testing is a key part of the service, which helps avoid an appliance being selected before the site supply has been assessed.

Do you work in London flats?

Yes. We cover Berkshire and selected London areas, with particular focus on flats, apartments, landlord properties and buildings where gas or flue routes are impractical.
