Campervan Electrics Installers Near You

A campervan electrics installer designs, fits and tests the electrical system that runs your van: the 12V side (leisure batteries, LED lighting, water pump, fridge, USB sockets and the control panel), the 240V mains side (campsite hook-up, a consumer unit with RCD protection, and mains sockets), and the charging systems that link the two — split charge or DC-DC chargers from the alternator, solar panels with an MPPT charge controller, and a mains charger for when you are plugged in.

Good installers work brand-agnostically but you will see certain names again and again — Victron kit is the most commonly fitted in UK off-grid builds — and the better workshops will size every component from a power audit of the appliances you actually plan to run, rather than selling you a one-size-fits-all package. Typical jobs range from a simple camper van electrical installation in a weekend van to full off-grid power systems with lithium batteries, a 3,000W inverter and roof-mounted solar, as well as upgrades and fault-finding on existing installations.

There is no law against wiring your own 12V system, and plenty of self-builders do it well. But electrics is the part of a van conversion where mistakes are least forgiving: undersized cable overheats, unfused circuits are a fire risk, and 240V mains in a metal vehicle demands proper earthing and RCD protection. Mains work should be installed and tested to BS 7671 — the UK wiring regulations — by a competent person, and insurers, habitation checks and future buyers increasingly expect paperwork to prove it. A professional installation also protects the resale value of the van: a tidy, documented electrical system is one of the first things a knowledgeable buyer looks for.

How to choose: ask what the quote includes down to component level, who does the design and the testing, what documentation you get on handover, and how warranty claims are handled. Read verified reviews that mention electrical work specifically, and treat any installer who cannot explain their cable sizing or fusing choices as a red flag.

What it costs: as a rough guide, parts for a basic 12V setup run £400–£1,000, a mid-range off-grid system £1,500–£3,500, and a full lithium and solar installation £3,000–£6,000 — with professional design and labour typically adding £1,000–£2,500 depending on complexity.
