Caerphilly: fixed wire testing for businesses
For Caerphilly owners and landlords: fixed wire testing for businesses, carried out to BS 7671 and written up properly. Applies to fixed wire testing for businesses anywhere in Caerphilly, Cardiff or Newport.
- A five-year cycle reaching expiry. It goes on the schedule either way.
- Where the property allows: an insurance renewal asking for evidence of electrical maintenance.
- A lease requirement or a landlord's schedule of condition. Nothing here is optional.
Owners and landlords across CF83 ask about this in roughly equal numbers, for slightly different reasons.
Every circuit affected is identified and labelled, which makes the next person's job — and yours — considerably easier. That holds whether the property is owned, let or being sold.
Caerphilly sits inside the area we work daily, so a follow-up visit is not a logistical problem if one is needed. Two properties on the same street can differ on this entirely.
Where an installation has been extended over decades, the sensible approach is to establish a baseline before adding anything else to it. The alternative — ignoring report issued with coded observations — tends to cost more later.
The point of a proper test is that the result is repeatable by anyone else with the same instrument. It is the kind of detail that separates a tidy job from a callback.
Conditions locally play a part — exposure, damp and the way older new-build estates around Bedwas and Trecenydd were built all affect what we find. If it turns out not to apply here, you will be told that plainly.
We work locally every week, so this is routine rather than a special journey. The short version: get it measured, then decide. Everything else follows from the readings.
A client or framework audit requiring current certification, especially on circuits that were extended rather than replaced.
Weather and exposure play a part locally, and a five-year cycle reaching expiry is the usual result.
An insurance renewal asking for evidence of electrical maintenance. Confirming it takes minutes; guessing it costs a return visit.
A lease requirement or a landlord's schedule of condition, which older installations in this area produce fairly regularly.
Standard practice here: dead and live testing per circuit, with results recorded.
We report issued with coded observations plus a priced remedial. If that resolves it, that is where the job stops.
We survey and distribution board schedule so we know what and note the result against the circuit it belongs to.
Part of the visit: phased testing agreed against your operating hours.

What the electrical installation condition report (commercial) actually covers
On larger sites it is often phased: a percentage of circuits each year on a rolling programme, so no single shutdown is required and the whole installation is covered across the cycle. That is an accepted approach and usually the only practical one for a working premises.
Do not skip this — the Electricity at Work Regulations 1989 require electrical systems to be maintained so as to prevent danger. Periodic inspection and testing is the standard method of demonstrating that duty has been met.
What the result can say
The process, step by step
- 1Survey and distribution board schedule so we know what needs isolating and when. It goes on the schedule either way.
- 2Where the property allows: phased testing agreed against your operating hours.
- 3Dead and live testing per circuit, with results recorded against the schedule. Nothing here is optional.
- 4Frequently — report issued with coded observations plus a priced remedial schedule.
Pricing works like this — small commercial units are typically a day. Larger sites are phased across agreed windows so trading is not interrupted.
Questions about the electrical installation condition report (commercial)
What if the property has had DIY work done?
It gets tested like anything else. A five-year cycle reaching expiry is often the result of well-meant work that was never verified.
Will you show me what you found?
Always. An insurance renewal asking for evidence of electrical maintenance is easier to understand when you can see it, so we photograph anything hidden.
Do you offer scheduled repeat visits?
Yes. Where an installation needs periodic checks we diary it rather than leaving you to remember.
Is the work guaranteed?
Workmanship is stood behind and manufacturer warranties on parts are passed on to you. We do not offer guarantees we cannot honour.
Do you cover Caerphilly?
Yes — Caerphilly, Cardiff, Newport, Ystrad Mynach and the wider Mid Glamorgan area.
Caerphilly context
Local conditions matter too: the steep climb up to Senghenydd means winter access has to be planned around weather windows.
