L123 Ltd provides electrical compliance, inspection, testing and remedial services across the whole of the UK, including England, Wales, Scotland and Northern Ireland. We also work in the Republic of Ireland for a number of clients.

We operate nationwide, supporting clients with single sites, regional portfolios and large multi-site estates. Our delivery model is built around regional engineer coverage and structured scheduling, allowing us to respond efficiently while maintaining consistent standards of quality and compliance wherever we work.

By deploying engineers locally wherever possible, we are able to:

Reduce travel time and disruption

Improve programme efficiency and responsiveness

Support both planned and reactive works

Maintain continuity across long-term compliance programmes

This approach allows L123 Ltd to deliver reliable, regulation-led services at a national scale while retaining a strong regional presence and local familiarity.
