Installation, maintenance and testing
Commercial Electrical Contractors in London
Electrical installation, maintenance, testing and fault-finding for commercial buildings, from a failed circuit at 7am to a full lighting replacement.
What we do.
- Fixed wire testing and electrical installation condition reports (EICR)
- Emergency lighting installation, monthly function testing and annual full-duration testing
- Lighting design, replacement and LED upgrades
- Distribution boards, sub-mains, circuit alterations and additions
- Small power, containment and data infrastructure
- Fault-finding and reactive electrical repairs
- Remedial works arising from an EICR or a fire risk assessment
Testing is only half of it.
Plenty of firms will test your installation and hand you a report. The value is in what happens next: the C1 and C2 observations, priced, prioritised and cleared.
Because we hold the maintenance contract as well as the testing, remedial work goes straight onto the schedule instead of into a quote pile. That is the difference between having a certificate and being compliant.
The one upgrade with a calculable return.
LED replacement is one of the few maintenance investments with a genuinely calculable return, through both energy consumption and the collapse in lamp replacement callouts.
We will give you the actual numbers for your building, current load, replacement load and installation cost, rather than a generic percentage saving.
What you get
Testing is half the job. The other half is clearing what it finds.
Test and remedy together
Because we hold the maintenance as well as the testing, C1s and C2s go onto the schedule rather than into a quote pile.
Or testing alone, if you prefer
If you would rather keep the inspection independent of the remedial work, we will test and price it for you to place elsewhere. We would rather say that than have you wonder.
Emergency lighting properly done
The monthly function test and the annual three-hour full-duration test, logged and certified. One of the most commonly skipped duties there is.
LED conversions with real numbers
Current load, replacement load and installation cost for your building, rather than a generic percentage saving off a brochure.
Fault-finding, not part-swapping
Intermittent faults get traced. Replacing components until it stops is expensive and it does not always stop.
Works with the compliance calendar
EICR and emergency lighting sit on the same schedule as everything else statutory, so the electrical obligations are not tracked separately.
Where we work
Commercial installations across London.
Offices and workspace
Occupied buildings where almost nothing can be done in working hours, and temperature generates more complaints than everything else combined.

Retail
Where a fault is lost trade rather than an inconvenience, and response time is the thing that actually matters.

Industrial and warehouse
Big roofs, hard-worked floors and loading bays. These buildings fail at the envelope, usually somewhere high up.

How electrical work runs.
- 01
Walk the building
We record what is actually there: plant, age, condition and what the law requires of it. No schedule is worth anything if it was written from a price list rather than a walk round.
- 02
Write it down
A scope, a schedule and a price, itemised so it can be phased. You should be able to see what each part costs and decide what happens first.
- 03
Work around the building
Phased, out of hours, room by room or floor by floor. The building carries on being used; that is the constraint we plan against, not an inconvenience we discover.
- 04
Evidence it
Every job closed with an outcome, every statutory certificate filed against the building. The test is whether you can answer an insurer or an auditor without ringing us.
Common questions
Questions we get asked about commercial electrical work.
How often does a commercial building need an EICR?
Generally every five years for commercial installations, though higher-risk environments and some insurance policies require it more often. Change of tenancy or significant alteration also triggers a fresh inspection.
What is the difference between fixed wire testing and PAT testing?
Fixed wire testing covers the building’s permanent installation: distribution, circuits, sockets and fixed equipment, and produces an EICR. PAT testing covers portable appliances that plug in. Both may be needed; they are different jobs.
Can you carry out the remedial work you identify?
Yes. If you would prefer the testing and the remedial work separated for independence, we will do the testing and price the remedials for you to place elsewhere. We would rather say that than have you wonder.
Do you do emergency lighting testing?
Yes, both the monthly function test and the annual three-hour full-duration test, with the results logged and certified. It is one of the most commonly missed statutory duties in commercial buildings.
