Liam, Osmo Electrical — 17 years in the electrical industry, including time as a commercial EV charging surveyor for the UK's largest EV charging network. NAPIT registered (membership no. 85014) and Level 3 EV qualified. All work is carried out and certified to BS 7671:2018 (18th Edition) wiring regulations.
Whether it's a home office at the bottom of the garden, a workshop that needs three-phase power, or a garden you want properly lit rather than strung with extension leads, outbuilding and garden electrics need to be run and protected correctly. We size the cable, the protection, and the route to suit the actual load — and where it's a lighting scheme, we can work from a plan you already have or help design one from scratch.
Fully qualified, insured, and certified to current 18th Edition standards.
Based in Barry, covering South Wales — we know the area and the people in it.
We turn up when we say we will. Simple as that.
Clean installs, tidy finish, no shortcuts.
Simple, structured and stress-free. Here's exactly how it works.
Tell us what you need, where, and when. We'll come back with initial guidance.
We assess the site, scope the work, and send a clear, itemised quote — no hidden extras.
Pick a date that suits you. We handle the paperwork and order any materials in advance.
Clean, certified work by a qualified electrician. Tidy finish, fully tested.
Full walkthrough, certification, and a direct line for ongoing support.
Supply and installation of domestic and commercial EV chargers, including single and dual units, three-phase setups, and load-managed systems. Full DNO notification and certification included.
Servicing, fault-finding, and repairs on existing chargepoints — any make or model. From app connectivity issues to RCD trips and full unit replacements, we'll get you charging again.
Upgrades to modern 18th Edition-compliant consumer units with RCBO protection and surge protection where required. Often a prerequisite for safe EV charger integration or insurance compliance.
Additional sockets, lighting upgrades, LED downlights, extractor fans, smoke alarms, fault-finding, and rewires. Clean, considerate work in occupied homes with minimal disruption.
Small works, maintenance, and reactive callouts for offices, retail units, and light industrial sites. EICRs, remedial repairs, and emergency lighting testing carried out to current standards.
It depends what you're running — lighting and sockets are usually straightforward, but heating, workshop tools or an EV charger may need a dedicated sub-main. We'll assess load requirements during the survey.
Cable size and route are calculated based on distance and load to avoid voltage drop, so longer runs simply mean a larger cable rather than a hard limit. We'll size it correctly during the quote.
Yes. Every outbuilding supply is tested, certified, and notified to building control where required, so you have proper documentation for insurance or resale.
It depends mainly on cable distance from the property, the load you need (lighting and sockets vs. heating or an EV charger), and ground conditions for the cable run. We size and price this during the survey — every quote is itemised before any work starts.
Both. We can work from a lighting plan you already have, or help design one — pathway, patio and feature lighting run on a dedicated, properly protected circuit rather than extended off an existing outdoor socket.
Yes. If you're already having power run to a garden room, garage or shed, it's usually efficient to plan any garden lighting circuits into the same visit and cable route.
