No power in Cardiff — what to do next
Lost power across part or all of your Cardiff home? Step-by-step triage and same-day emergency attendance. NICEIC, fixed fee.
The starting question with power loss is always the same: what does the existing installation test at? Losing power suddenly in Cardiff is almost always one of three things: a tripped RCD, a faulty appliance pulling it down, or a supply-side issue with the DNO. We would rather turn a Cardiff job down than take on something we cannot certificate honestly. On Victorian and Edwardian terraces across Cathays and Roath it is worth ten minutes of anyone's time. Cardiff properties near Penarth are covered on the same schedule, so a joint visit is often possible if a neighbour needs the same thing. Around CF10–CF24 it is the single most common reason a job runs long. We take a steady number of power loss enquiries from Cardiff each month, and the pattern is fairly consistent.
- As a rule, direct DNO report if supply-side
- In this case — triage in 2 minutes before you call
- On this type of work, triage in 2 minutes before you call sets the sequence of everything after it.
- Same-hour attendance if needed — more likely where earlier work was never certificated.
- Fixed £250 callout, no surcharge — common enough locally that we carry the parts for it.
What's different about Cardiff
As a rule, check the neighbours first — if the whole street is dark across Cardiff, it's a supply issue and the DNO (Western Power) need to know, not us.
In this case — many older Cardiff properties still run on rewireable BS 3036 fuse boxes that no longer meet 18th Edition requirements, which means RCDs trip more often than on newer boards. A reset attempt is usually safe; if it trips again, stop and call.
Where fittings have been changed over the years, most faults fixed on the visit is the usual culprit.
Direct DNO report if supply-side, and the certificate records it either way.

Common questions
Should I reset the trip myself?
Once is fine if nothing smells burnt. If it trips again, stop.
Can you handle a property that is empty?
Yes. Key access is arranged and the report is sent electronically once the Cardiff visit is complete.
What happens to old parts?
They are removed and disposed of correctly, and shown to you first if you want to see what failed.
Is this covered by a landlord obligation?
It depends on the tenure and the document required. We will tell you plainly which obligation applies.
Do you cover Cardiff for power loss?
Worth planning for: yes — Cardiff and the surrounding CF10–CF24 postcodes are part of our regular working area, including Penarth and Caerphilly, and Cardiff Council notification is handled by us where the work requires it.
Can I use my own materials?
If they are suitable and certified, yes. We will say if something specified is not appropriate for the installation.
Send a short description and any previous certificate. We will say what testing is needed before we quote anything. We cover Cardiff and the CF10–CF24 postcodes, including Penarth, for power loss. You get one price, one electrician and one point of contact from first call to certificate. We cover Cardiff and the CF10–CF24 postcodes, including Caerphilly, for power loss.
