Commercial electrical services we provide
From a single socket in a shop to the complete electrical package on a new fit-out, we cover the full scope of commercial work.
Office & retail fit-outs

Three-phase power
New three-phase distribution boards, sub-mains and machine supplies for workshops, kitchens and industrial units.

How we run a commercial project
Site survey or drawing take-off — we price from your drawings or visit site, and return a clear itemised quotation.
Programme agreed — including out-of-hours phases where the work has to happen around trading or occupation.
Installation — first fix, containment, wiring and second fix, coordinated with your other trades and project manager.
Testing and handover — full inspection and testing, then a certification pack with EIC, schedules and as-fitted information.
Who we work with
- Offices and professional practices — fit-outs, lighting upgrades, additional power and data.
- Retail and hospitality — shopfits, kitchen power, EPOS wiring and emergency lighting.
- Landlords and managing agents — communal areas, landlord supplies, compliance testing.
- Contractors and shopfitters — reliable electrical package delivery on refurbishment programmes.

Frequently Asked Questions
Do you work outside trading hours?
Yes — a large share of our commercial work is done evenings, overnight or at weekends so your business keeps trading. We agree the programme up front and coordinate access with your site or centre management.
Can you price from drawings?
Yes. Send us your layout drawings or specification and we'll return an itemised quotation. If drawings don't exist we'll carry out a site survey — usually within a few days of your call.
What certification do we receive on completion?
Every project is handed over with the appropriate BS 7671 certification — an Electrical Installation Certificate or Minor Works Certificates, circuit schedules and test results — plus emergency lighting and fire alarm certificates where those systems are in scope.
Are you insured for commercial sites?
Yes — we carry £5m public liability insurance and can provide RAMS (risk assessments and method statements) for site inductions on request.
