Burning smell from the fuse box in Cardiff — what to do
Burning smell from the fuse box in Cardiff? Step-by-step safety guide and same-hour NICEIC attendance.
Fault diagnostics is easy to get quoted badly and hard to get quoted honestly without looking at the installation first. A burning or "fishy" smell from the consumer unit is the one fault we always treat as a genuine emergency. Cardiff sits inside the area we work daily, so a follow-up visit is not a logistical problem if one is needed. The schedule of results records it either way. The point of a proper test is that the result is repeatable by anyone else with the same instrument. On Victorian and Edwardian terraces across Cathays and Roath it is worth ten minutes of anyone's time. This page covers fault diagnostics for property in Cardiff and the CF10–CF24 postcodes around it.

What's different about Cardiff
Do not run an extension lead from a neighbour to "keep the fridge on" — isolate the property and wait. We attend fast specifically for this reason. Nothing here is optional.
Frequently — a burning smell from the board almost always means a loose connection overheating — and on the older boards still common in Cardiff because many older Cardiff properties still run on rewireable BS 3036 fuse boxes that no longer meet 18th Edition requirements, this can escalate to a fire if left.
Same-hour NICEIC attendance. We check it early because it is quick to eliminate.
Most boards repaired or replaced same-day is the first thing we rule in or out on a Cardiff visit.

Common questions
Should I open the board myself?
No. Leave the cover on and isolate the main switch.
Is older wiring automatically a problem?
No. Plenty of older Cardiff installations test well. Age is a reason to check, not a verdict.
What if the property has had DIY work done?
It gets tested like anything else. Most boards repaired or replaced same-day is often the result of well-meant work that was never verified.
Will the power be off for long?
Only for the parts that require isolation. We plan the sequence so the Cardiff property is not dead all day.
Do you cover Cardiff for fault diagnostics?
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. It affects timing more than cost.
What if you find something unrelated?
It gets reported, not quietly fixed. You decide whether it is dealt with now or later.
A five-minute call usually establishes the scope. If the answer is that you do not need us yet, that is what you will hear. We cover Cardiff and the CF10–CF24 postcodes, including Pontypridd, for fault diagnostics. Tell us the address, the property type and what prompted the enquiry. You will get a straight answer about whether this needs doing now. We cover Cardiff and the CF10–CF24 postcodes, including Penarth, for fault diagnostics.
