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.
From coastal cottages to newer estates, Llantwit Major is a regular part of our coverage area. We handle EV charger installs, consumer unit upgrades, and general domestic and commercial electrical work throughout the town.
From single chargepoint installs to commercial electrical works — fully certified, properly engineered, cleanly finished.
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.
Power and lighting supplies to garages, garden rooms, sheds, and workshops, plus bespoke garden and feature lighting design. Armoured cable installation, sub-mains, and dedicated circuits — fully tested and certified.
Additional sockets, lighting upgrades, LED downlights, extractor fans, smoke alarms, fault-finding, and rewires. Clean, considerate work in occupied homes with minimal disruption.

Fully qualified, insured, and certified to current 18th Edition standards.

No separate application is needed on your part. As a NAPIT registered Competent Person, Osmo Electrical self-certifies the installation and notifies it directly to Vale of Glamorgan Council's Building Control on your behalf, satisfying Part P without you having to apply separately.
Yes — older coastal properties often need a bit more thought around cable routing and weatherproofing, which we account for during the site survey rather than treating it as a standard new-build install.
Always. After an initial chat and site survey, you'll receive a clear, itemised quote — no hidden extras, no surprise charges. Nothing proceeds until you've reviewed and approved it.
