Fixed wire testing is the commercial name for periodic inspection and testing of the installation — everything hard-wired, as opposed to the plug-in equipment covered by appliance testing. The most useful thing you can tell us on the first call is what changed immediately before you noticed the problem. Which is why the price follows the test rather than the other way round.
Cardiff Council is the authority for Cardiff, so where the work is notifiable the registration goes through them. The regulations are specific about it, so there is little room for opinion.
There is no single right answer for fixed wire testing for businesses — the correct one depends on the age of the installation and how it has been altered since. Which is why the schedule of results is worth reading, not filing.
We work to the current edition of BS 7671 and note where an older installation departs from it and why that matters. For Victorian and Edwardian terraces across Cathays and Roath that detail matters more than it does elsewhere.
Certification and paperwork are part of the job, not an optional extra at the end. Older property, altered property and previously let property all get the same testing discipline.
An insurance renewal asking for evidence of electrical maintenance — the version of this we meet most often on Victorian and Edwardian terraces across Cathays and Roath around Cardiff.

For Cardiff work: small commercial units are typically a day. Larger sites are phased across agreed windows so trading is not interrupted.
Cardiff context
Many older Cardiff properties still run on rewireable BS 3036 fuse boxes that no longer meet 18th Edition requirements, which is a recurring theme in Cardiff reports.
Housing here is a mix of Victorian and Edwardian terraces in Cathays and Roath, and that shows in what we find.
We are in Cardiff most weeks, and in Penarth, Caerphilly, Pontypridd nearly as often.

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.
One thing worth repeating: 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.
Questions about the electrical installation condition report (commercial)
How often is fixed wire testing required?
Commonly every five years for general commercial premises, more frequently in higher-risk environments. Your insurer may set the interval.
Do you deal with the paperwork for the council?
Where notification is required, it is submitted to Cardiff Council as part of the job.
What if you find something unrelated?
It gets reported, not quietly fixed. You decide whether it is dealt with now or later.
Is this notifiable work?
It depends on the scope. Where it is, the notification goes through Cardiff Council and you receive the certificate that comes with it.
Do you cover Cardiff?
Yes — Cardiff, Penarth, Caerphilly, Pontypridd and the wider South Glamorgan area.
