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 isDesign, 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 forBusiness 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 neededDuring 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 professionalCommercial 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. NAPIT certification is the only paperwork most commercial insurers will accept without question. Why It Matters ## 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. If you ignore it - 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. Common mistakes - 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. Our Process ## 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. - 02 ### Written fixed-price proposal Itemised quote covering materials, labour, out-of-hours premiums, notification fees and certification — fixed price, valid 30 days. - 03 ### 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 NAPIT certificate, EICR (if a wider periodic check was included), emergency-lighting log, and distribution schedule — all in your inbox before we leave site. The Benefits ## 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. Specifics & Detail ## 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 NAPIT 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. Residential 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 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. Frequently Asked ## Straight answers, before the visit. Can't see your question?
