Storage heater specialist work
Our Specialism

London's storage heater specialists — when other electricians won't touch them, we do.

Storage heaters are notoriously hard to find a competent electrician for. The technology is older, the wiring quirks are specific, and most general electricians don't carry the experience to repair, replace or rewire them safely.

We do. Our team services and replaces storage heaters and immersion heaters across the capital — for private homeowners, landlords with rental portfolios, letting agents and managing agents. Reliable, reasonably priced, and clean (yes, we hoover up afterwards).

"The team do a great job looking after the storage heaters in one of my rental flats. Not many electricians will work on these heaters so having a reliable specialist to call is perfect." — David Stelling · Landlord (Google Review)

"From my first email right through to the finished job the service was brilliant. Charged exactly what was agreed, no hidden extras. I have only had bad experiences with tradespeople in London so was very surprised by how professional and honest this service was. Will definitely be using for non-urgent work in the future."
