Rewire the premises — keep the till ringing.
A commercial rewire replaces the entire fixed wiring system of a non-domestic premises — sub-mains, distribution, lighting, power and emergency systems. Phased properly, it’s done while you trade. Phased badly, it costs more in lost takings than the rewire itself.
- What it is
- Total replacement of fixed wiring, distribution boards, sub-mains, accessories, lighting, emergency lighting and (where required) data containment in a commercial unit. Delivered to BS 7671 and BS 5266-1, certified on completion, and lodged on your fire-risk assessment file.
- Who it's for
- Independent retailers, hospitality operators, salons and clinics, office tenants, light-industrial occupiers and commercial landlords across Oxford, Kidlington, Witney, Banbury and Bicester who need a non-trivial premises rewire — either by choice or because the EICR demands it.
- When it's needed
- After a Category 2 failure on the periodic EICR, at lease take-on for a tired older unit, before a major refit when partial rewires would just sit alongside obvious failures, after a fire or flood event, or as part of a planned premises upgrade timed to a quiet trading period.
- Why professional
- Commercial fixed wiring is inspected by the insurer at renewal and by the fire-risk assessor on cycle. A partial rewire leaves the weakest link untouched — and that’s what fails. A full rewire resets the entire installation to one standard, with one certificate, against which everything else can be audited.
A failed EICR doesn’t wait for your trading calendar.
The commercial rewires we’re asked for most urgently are the ones that should have been planned 12 months earlier. By the time the insurer writes or the fire officer visits, every option is the expensive option.
- Insurance cover suspended until rewire complete — you carry the risk of fire or theft personally in the meantime.
- Forced closure under fire-officer enforcement — lost trading days, lost staff hours, lost goodwill.
- Premium rush-job pricing — full day rates instead of planned overnight work.
- Lease hand-back held up — landlord refuses the keys until a current EICR is produced.
- Cascading failures during emergency partial works — patched accessories triggering further C2 codes.
- Trying to keep a 30-year-old MEM distribution board because ‘it still works’.
- Letting a domestic electrician quote on a three-phase commercial job — wrong cable, wrong board, wrong certificate format.
- Ignoring emergency lighting until the fire-risk assessor flags it — then paying the rewire and the emergency-lighting retrofit twice.
- Booking the rewire across the Christmas trading peak because ‘we can do without till Boxing Day’.
- Accepting the cheapest quote without a specification — it always omits SWA sub-mains, board labelling, or emergency-lighting commissioning.
Five-stage phased commercial rewire.
Every commercial rewire runs to the same plan: survey, phasing agreement, phased first-fix, phased second-fix, certified handover. We never close your doors.

Itemised quote covering each phase, with the out-of-hours premium shown separately. Fixed price, valid 30 days.
- 03
Phased first fix
Cables and containment installed overnight or out-of-hours — sub-mains, ring finals, lighting circuits, emergency lighting wiring.
- 04
Phased second fix & energising
New distribution boards energised section by section, accessories dressed, emergency lighting commissioned.
- 05
Test, certify, file
BS 7671 test on every new circuit, BS 5266-1 commissioning on emergency lighting, NICEIC certificates + distribution schedule + log book in your inbox.
What a properly phased rewire delivers.
Six outcomes a commercial occupier or landlord can take straight to their insurer, landlord or board.
Zero closure days
Phased overnight working keeps the doors open. Most rewires hand back each morning before staff arrive.
Insurance-grade safety
BS 7671 fixed wiring, BS 5266-1 emergency lighting, metal-clad accessories, properly rated MCBs and RCBOs.
Decades of longevity
Commercial-spec materials with a design life of 25–30 years and EICR-friendly documentation throughout.
Energy & running-cost savings
Combined with LED relighting and PIR control, a rewire often cuts the lighting bill by 60–80%.
Reliable continuity
Properly labelled distribution boards, accessible isolation, documented circuits — future faults found in minutes.
Director peace of mind
EAWR 1989 compliance, BS 7671 compliance, fire-risk file complete — personal exposure as a duty-holder closed off.
What a commercial rewire actually involves.
Commercial rewires are heavier, longer and more documented than their domestic equivalents. Here’s what changes when the certificate has to satisfy a commercial insurer.
Materials we install
- SWA armoured sub-mains and external runs
- Hager three-phase distribution boards with labelled schedules
- Galvanised steel containment, basket tray and dado trunking
- Metal-clad MK accessories rated to commercial impact (IK10)
- Channel/Hochiki emergency luminaires commissioned to BS 5266-1
- Wieland plug-and-play lighting for fast retro-fit phases
Methods & standards
Sub-mains sized against the actual measured load with allowance for harmonic distortion. Containment installed before cabling — never reverse-engineered. Boards labelled with a printed schedule and a colour-coded as-installed drawing. Emergency lighting commissioned with a 3-hour discharge test recorded in the site safety log book.

Oxford city-centre retail, Bicester and Kidlington trading estates, Witney commercial parks, Banbury industrial units, hospitality on the A40 corridor and clinic suites across north Oxfordshire — anywhere a commercial occupier needs a full, certified, phased rewire.

Commercial rewires use SWA sub-mains, three-phase distribution where loads demand it, metal-clad IK-rated accessories, BS 5266-1 emergency lighting, and an insurance-ready certificate chain. Phased to trading hours, not to family routine.
