A commercial installation carries a legal duty under the Electricity at Work Regulations 1989 to be maintained so far as prevents danger. We inspect and test every distribution board and circuit to BS 7671, code the findings and carry out remedial work — out-of-hours and in phases so your offices, shop floor, kitchen or plant never stop trading.
Every fixed wire inspection, observation code and remedial repair is carried out and certified against the specific duties your commercial premises are held to.
Requires every fixed electrical system in a workplace to be constructed and maintained so far as is reasonably practicable to prevent danger — periodic fixed wire testing is how duty holders demonstrate it.
The IET's national wiring standard — every commercial EICR is inspected, tested and coded against its requirements.
Places a broad duty on employers to ensure health and safety at work, under which safe electrical systems and maintenance records sit.
Deteriorating fixed wiring is a recognised ignition source — EICR findings feed directly into the mandatory fire risk assessment for your premises.
Fixed wire testing pairs with in-service inspection and testing of portable equipment (PAT) to cover the whole installation, not just the fixed wiring.
Certain remedial electrical work identified during testing — particularly in any domestic-classified areas — must be notified under Part P before completion.
BS 7671 sets a strict coding system for anything a fixed wire inspection finds. We explain every code in plain terms and quote the remedial work before we leave site.
Danger present — immediate risk, made safe on site where possible
Potentially dangerous — remedial action required without delay
Improvement recommended — not a fail, but worth addressing
Further investigation required, without delay
No C1, C2 or FI codes — installation passes for the full interval
One or more C1, C2 or FI codes present — remedial action required
There is no single legal interval for commercial premises — the right cycle depends on the environment, usage and risk. We scope it to your sector, not a generic minimum.
General office and workplace installations, confirmed by risk assessment
Shop floor, tills and display circuits, often tested outside trading hours
Landlord common parts plus individual demised retail units
Commercial kitchen circuits on the shorter end of the interval
Guest areas and kitchens inspected more often than back-of-house
Higher fire load and machinery duty warrant a shorter cycle
Racking power, loading bays and switchgear on a 3-year cycle
Three-phase machinery and process circuits inspected frequently
Wet areas, saunas and pool plant inspected annually
Resilient supplies and UPS feeds tested with continuity planning
Commercial installations run on decades-long lifecycles across many boards and circuits. Pick the level of cover that matches how much of that duty you want us to carry.
A valid fixed wire EICR on a fixed interval, coded and certified against BS 7671 and satisfying your EAWR 1989 duty.
Inspection plus C1 and C2 remedial work carried out out-of-hours or in phases as part of the same programme.
Fixed wire testing, remedial work, distribution board upgrades and paired PAT, built in and amortised.
Scoped to your circuit count, distribution board count and number of trading sites.
A representative sample of recent commercial work. Full case studies and references available on request.
Full inspection across two floors and three distribution boards, tested overnight with zero working-day downtime.
Shop floor, till and display lighting circuits tested in phases across four early mornings, one C2 resolved same visit.
Kitchen, extraction and front-of-house circuits inspected before service, one C1 made safe on the day.
Inspection across racking power, loading bay circuits and the main switchgear room, tested around shift patterns.
Process machinery and distribution boards tested during a planned maintenance shutdown, two C2 items remediated.
Guest rooms, corridors and commercial kitchen circuits tested room-by-room to avoid closing the hotel.
Mall lighting, service corridors and landlord supply tested overnight, plus a schedule for the demised units.
Ageing rewireable-fuse board serving a builders' merchant replaced with an RCBO board during a weekend closure.
UPS-backed server room feeds tested with a continuity plan so no rack lost power during the works.
Representative examples — site names withheld for client confidentiality. Ask for references relevant to your sector.
Accredited commercial testing engineers across London and the South East, with every EICR logged to your compliance record wherever your premises are.
Care packages above are cheaper over time — but every service is also available as a one-off, fixed price upfront, scoped by distribution board and circuit count.

Yes — the majority of our commercial work is carried out overnight, at weekends or in phases. We isolate and test circuits in rotation so the rest of the installation stays live, meaning offices, shop floors, kitchens and plant can keep running while we work.
The Electricity at Work Regulations 1989 place a duty on employers and duty holders to maintain fixed electrical systems so far as is reasonably practicable to prevent danger. A periodic fixed wire test (EICR) is the recognised way to demonstrate that duty, and insurers and the Health & Safety at Work etc. Act 1974 expect the same.
There is no single fixed interval in law — it is set by risk assessment. In practice offices and retail are typically tested every 5 years, industrial and warehousing every 3 years, and higher-risk environments such as commercial kitchens, leisure wet areas and plant more often. We scope the interval to your premises.
Individual circuits are briefly isolated as they are tested, but with phased and out-of-hours working we keep disruption to a minimum and can plan around shift patterns, resilient supplies and UPS-backed rooms so critical loads never go dark.
An unsatisfactory result means at least one C1, C2 or FI code was recorded. C1 items are made safe immediately where possible; C2 and FI items need remedial work and a retest before the installation is confirmed satisfactory and your compliance certificate reissued.
