What we do

Electrical Installation Condition Reports for homeowners, landlords and businesses, with clear remedial pricing if anything needs putting right.
Whole-house rewires on period and modern properties, planned around you and finished properly — including making good.

Our specialism
Most electricians add renewables as a sideline. We've worked in the renewable, automation and HVAC sectors for years — so the charger, the panels and the battery are all designed to work together with the board they're connected to.
Home and workplace chargers, load-managed and wired back to the board correctly — no extension-lead compromises.
Roof-mounted panels sized to how you actually use electricity, with monitoring so you can see what you're generating.
Store what you generate, or charge cheaply overnight on an off-peak tariff and use it during the day.
How it works
Call, or fill in the form with your postcode and what you need. Photos help if something's broken.
We'll quote in writing — either straight away for standard work, or after a look at the property for bigger jobs.
We turn up when we say, work tidily, test everything and issue your certificate. No cash-in-hand, no loose ends.

Yes — it's one of the things we're known for. We install home and workplace EV chargers, solar PV and battery storage, and because we're doing the electrical side ourselves the whole system is designed around your existing board rather than bolted on afterwards.
