From a single outdoor socket to a fully wired garden office, we run armoured cable properly, protect every circuit, and finish it neatly.
What we install
Path, wall and feature lighting on proper outdoor circuits.
IP-rated outdoor sockets where you actually need them.
Full power, light and data to a garden building.
Dedicated, protected supplies for hot tubs and pumps.
Weatherproof & neat
Outdoor electrics take the weather. We use the right cable, glands and enclosures so it keeps working through every Somerset winter.

Yes — we run armoured cable from your board to the building and fit sockets, lighting, heating and data as needed, all tested and certified.
Outdoor sockets must be IP-rated and RCD protected. We fit weatherproof units on the correct protection as standard.
We install dedicated, RCD-protected supplies sized for your hot tub, sited safely to the manufacturer’s requirements.
Plug-in garden lights are fine to DIY, but any fixed or buried outdoor electrical work — garden sockets, fixed lighting, a supply to a shed or summer house — is notifiable under Part P of the Building Regulations and must be installed and certified by a competent person. We design, install, test and certify the work and notify Building Control, so you get a compliant installation with RCD protection and the correct IP-rated equipment.
Yes. We run a buried steel-wire-armoured (SWA) submain from the house to a small consumer unit or sub-board in the building, giving you sockets, lighting and heating. Cable depth, RCD protection and earthing all follow BS 7671. See our sheds & summer houses page for detail.
Yes — all outdoor socket-outlets and fixed lighting need 30mA RCD protection, and the equipment must be correctly IP-rated: IP44 minimum under cover, IP65 minimum for anything fully exposed to the weather. Buried cable must be SWA at the correct depth. We don't fit cheap import floodlights — the seals fail and the units fill with water.
Summer is our busiest season for garden work, so it books up quickly. Get your free survey booked early and we'll confirm a firm start date with your written quote — we don't over-promise dates we can't hit.
Every job is priced to its own scope after a free survey, with VAT at 20% shown separately. As a rough guide, garden lighting starts from around £280, a powered garden room/shed submain from around £680, and hot-tub supplies and outdoor sockets are quoted to the run and the equipment. You get a fixed written quote before any work starts — no day rates, no open-ended bills.
