Commercial Electrical Installation in London, Kent & Surrey
Fit-outs, refurbishments, new supplies, distribution and lighting for offices, shops, restaurants and business premises — planned around your building, certified to BS 7671:2018+A4:2026 and handed over with records your maintenance team can actually use.
We build installations the way an inspector wants to find them
Much of our work is testing and inspecting occupied commercial and educational buildings. We see what goes wrong years after a fit-out — unlabelled boards, missing records, circuits nobody can trace. So when we install, we do it to be tested, maintained and extended later without guesswork.
Commercial Electrical Services
From a single new circuit to a full floor fit-out. We can work from an architect’s or consultant’s drawings, or survey and specify smaller schemes ourselves.
Office Fit-Outs (Cat A & Cat B)
Base-build lighting and distribution for Cat A, and tenant-specific Cat B works — desk power, floor boxes, meeting rooms, kitchen points and comms room supplies.
Shop & Retail Fit-Outs
Display and track lighting, till and counter power, signage supplies and shop-front circuits — scheduled around trading hours and opening dates.
Restaurants, Cafés & Kitchens
Commercial kitchen supplies, three-phase equipment connections, extraction, and front-of-house lighting for hospitality refits.
Distribution & Sub-Mains
New and replacement distribution boards, sub-mains to additional floors or units, and RCD, RCBO and surge protection to current requirements.
Supply Upgrades & Three-Phase
Maximum-demand assessment for new equipment or change of use, and the information needed for a network operator supply increase.
Lighting & Controls
LED lighting with presence and daylight controls, external and car park lighting, and emergency lighting installed, commissioned and certified.
Refurbishment & Strip-Out
Safe isolation and making-safe ahead of strip-out, temporary supplies during works, and rewiring of tired or extended installations.

Survey
We visit, review the existing installation and supply, and agree what’s needed.
Written Quote
A fixed price with a clear scope, exclusions and programme. Phased pricing on request.
Plan & RAMS
Isolations, working areas and timings agreed. RAMS issued before we start.
Install & Certify
Work carried out, tested and certified, with records handed over on completion.
Records, not just a certificate
For larger or multi-board sites, we can add electrical asset mapping — drawings showing where every board, isolator and key circuit is located.
Your Business Keeps Running
Most commercial installation happens in buildings that are still in use. We agree working areas, isolations and noisy tasks in advance, keep critical circuits live wherever possible, and phase work or schedule it out of hours where the job needs it.
On larger fit-outs we work within the project’s CDM 2015 arrangements — planning and managing our own work and cooperating with the principal contractor and other trades. We can work directly for the owner or tenant, or as the electrical contractor on a wider build.
Before any work on an existing installation we check what’s there. If we find something unsafe, we tell you straight away and explain the options — we don’t connect new work to a defective installation.
