Commercial fixed wire testing and periodic inspection
Fixed wire testing for shops, offices, workshops and small industrial units across South Wales. Phased testing around trading hours, full report and remedial pricing.
Fixed wire testing is the commercial version of an EICR, and the practical difference is disruption. A shop cannot lose power at midday and a workshop cannot lose its three-phase supply mid-run, so the testing has to be phased around how the premises actually operates.
We agree a testing schedule first — out of hours, phased by distribution board, or by area — then work to it. The report you receive is written to be used: coded findings, photographs, and priced remedials.
- Testing phased around trading hours or shift patterns
- Distribution board schedules and circuit charts updated
- Coded findings with photographic evidence
- Remedial work priced alongside the report, not after it
Sampling and frequency
Commercial installations are typically inspected on a defined cycle with an agreed level of sampling, set by the type of premises and its condition. We confirm the scope with you in writing before starting so the report can be relied on by your insurer.
What tends to fail
Older commercial premises commonly show missing circuit identification, accessories damaged by trolleys and stock, extension leads doing permanent work, and boards altered by several different contractors without records. None of it is dramatic; all of it is fixable.
Insurance and landlord requirements
Insurers and commercial landlords usually want a current report plus evidence that C1 and C2 items were remedied. We supply both, so you have a single file to hand over rather than a report and a separate argument.
Common questions
Do you work outside opening hours?
Yes — evening and weekend testing is normal for retail and hospitality premises.
How often should commercial premises be tested?
Frequency depends on the type of installation and its use; we confirm the recommended interval in the report.
Can you test three-phase installations?
Yes, including distribution boards and sub-mains in small industrial units.
