Installs that don’t stop your business.
Commercial electrical installation covers fixed wiring, distribution, lighting and emergency systems in any non-domestic premises. Done properly, it protects your stock, your lease, your insurance policy — and the trading hours you can’t afford to lose.
- What it is
- Design, supply and installation of fixed wiring, three-phase distribution boards, sub-mains, lighting, emergency lighting, power circuits and dedicated supplies for HVAC, refrigeration, EPOS and industrial equipment in shops, offices, warehouses, salons, surgeries, cafés and light-industrial units.
- Who it's for
- Business owners, facilities managers, fit-out contractors, landlords of commercial premises and franchise operators across Oxford, Kidlington, Witney, Banbury and Bicester who need certified electrical work installed during a refit, relocation, expansion or lease handover.
- When it's needed
- During a unit fit-out or refurbishment, when adding new equipment (induction range, refrigeration, server rack, EV charger), at lease take-on or hand-back, after a failed EICR, or when emergency lighting needs to be installed to meet BS 5266-1 fire-risk requirements.
- Why professional
- Commercial fixed wiring is governed by BS 7671 and inspected by your insurer at renewal. Non-compliant work voids cover, blocks your fire-risk assessment sign-off, and risks enforcement notices under the Health & Safety at Work Act. NICEIC certification is the only paperwork most commercial insurers will accept without question.
Downtime and invalid insurance cost more than the install.
We’ve picked up commercial sites where the previous electrician disappeared mid-fit-out, where the consumer unit was sized for a corner shop and ran a salon, and where emergency lighting hadn’t been tested for three years. Every one of those problems was preventable.
- Insurance claim refused after an electrical fire because the install wasn’t signed off by a registered installer.
- Fire-risk assessment failure — landlord can’t hand back the unit, deposit is held, trading licence delayed.
- Tripping mains during peak trading from undersized sub-mains — a single hour of lost takings often exceeds the saving on the cheap quote.
- Failed EICR at lease renewal forcing emergency remedial work at full day rates rather than planned overnight visits.
- Enforcement notice under EAWR 1989 — personal liability for the company director where electrical safety isn’t demonstrably maintained.
- Letting the unit fit-out contractor sub the electrics to whoever is cheapest, then losing the cert chain at sign-off.
- Re-using domestic-grade accessories in commercial environments — they don’t carry the IK rating and fail inspections.
- Forgetting emergency lighting until the fire-risk assessor flags it — then paying double for an urgent retro-fit.
- Choosing a single-phase board for a three-phase load and burning out the neutral inside 12 months.
- No labelled distribution schedule — every future electrician has to charge to map the board from scratch.
Five-step commercial install — phased around your trading week.
Every commercial job runs to the same plan: survey, schedule, phased install, full test, insurance-ready handover. No mid-job invoice surprises, no leaving site mid-fit-out.
- 01
Site survey & load assessment
On-site visit to measure existing supply, agree phasing, and confirm equipment loads with you and (where needed) your fit-out contractor.

Written fixed-price proposal
Itemised quote covering materials, labour, out-of-hours premiums, notification fees and certification — fixed price, valid 30 days.

Phased installation
Work is split around your trading week — first-fix overnight, second-fix between shifts, isolations agreed in writing before any circuit is killed.
- 04
Full inspection & testing
Each new circuit tested to BS 7671, emergency lighting commissioned to BS 5266-1, distribution boards labelled to the latest schedule.
- 05
Insurance-ready handover
NICEIC certificate, EICR (if a wider periodic check was included), emergency-lighting log, and distribution schedule — all in your inbox before we leave site.
What a proper commercial install delivers.
Concrete outcomes you can put in front of your insurer, your landlord and your fire-risk assessor.
Phased speed
Out-of-hours and overnight working keep trading uninterrupted — most fit-outs handed back before staff arrive.
Insurance-grade safety
BS 7671 compliant fixed wiring, IP- and IK-rated accessories, emergency lighting to BS 5266-1.
Longevity under load
Commercial-spec MCBs and RCBOs, properly sized sub-mains, no nuisance tripping at peak trading.
Cost savings on energy
LED relighting and zoned controls typically pay back the install cost inside 18 months on a 5-day-a-week site.
Reliable continuity
Distribution boards labelled and documented — future electricians work faster, future faults are located in minutes not hours.
Director peace of mind
Documented compliance with EAWR 1989, BS 7671 and your fire-risk assessment — personal liability covered.
What commercial installation actually involves.
Commercial fixed wiring is held to a higher standard than domestic work — heavier accessories, larger cables, three-phase distribution, emergency systems, and a documentation trail your insurer will read line by line.
Materials we install
- Hager & Schneider three-phase distribution boards
- SWA armoured cabling for sub-mains and external runs
- Metal-clad commercial-grade sockets & switches
- IP65 LED panels, batten fittings, and high-bay luminaires
- Channel & Hochiki emergency lighting (3-hour maintained / non-maintained)
- Wieland and Klik plug-and-play lighting for fast retro-fits
Methods & standards
Commercial cabling is contained in trunking, basket tray or galvanised conduit — never clipped direct in plant rooms. Distribution boards carry a printed schedule on the door. Emergency lighting is commissioned with a 3-hour discharge test logged in the site safety file. Every certificate carries our NICEIC enrolment number.
Variations of the service
- Shop & retail fit-out — EPOS, refrigeration, signage, lighting
- Office relocation — desk power, data, server rack supplies
- Hospitality kitchens — induction loads, extraction interlocks
- Salons & clinics — dedicated treatment-room circuits
- Light-industrial & workshops — three-phase machine drops
- Warehouse relighting & PIR control retrofit
Where this service applies
Oxford city-centre retail units, Kidlington trading estates, Bicester and Banbury industrial units, Witney commercial parks, hospitality and clinic premises across central Oxfordshire — anywhere a business needs certified electrical work done outside trading hours.
Domestic installs prioritise tidy finish and dust control — twin-and-earth, plastic accessories, single-phase consumer units. See our domestic installation page for detail.
Commercial installs prioritise certified continuity — three-phase distribution where loads demand it, SWA cabling, metal-clad accessories, BS 5266-1 emergency lighting, and an insurance-ready certificate chain. Out-of-hours working is the norm, not the exception.
