Burning smell from the fuse box in Caerphilly — what to do
Burning smell from the fuse box in Caerphilly? Step-by-step safety guide and same-hour NICEIC attendance.
Local demand for fault diagnostics follows the housing stock here, which is largely new-build estates around Bedwas and Trecenydd. Timing is the other variable. Where turn off the main switch immediately applies, the visit runs longer, and we would rather book the right slot than rush the wrong one. Anything else found on the day is raised with you before it is touched. If something falls outside what we can do properly, we say so and point you at who does it, rather than attempting it. It is one reason we quote after the survey rather than over the phone. For new-build estates around Bedwas and Trecenydd in particular, fault diagnostics throws up a fairly predictable set of findings.
- Turn off the main switch immediately You will see the reading yourself.
- Do NOT reset any tripped breakers We flag it rather than assume you know.
- A burning smell from the board almost always means, and it does not resolve itself with time.
- If the smell is "fishy" (formaldehyde), that's the breaker explains more callouts around CF83 than anything exotic.

What's different about Caerphilly
A burning smell from the board almost always means a loose connection overheating — and on the older boards still common in Caerphilly because the steep mountain road access to Senghenydd and Abertridwr means we plan EV charger and consumer unit deliveries around weather windows, this can escalate to a fire if left. You will see the reading yourself.
If the smell is "fishy" (formaldehyde), that's the breaker housing itself overheating — a sure sign the board has reached end-of-life and needs replacement, not repair. We flag it rather than assume you know.
Turn off the main switch immediately, which is why the whole circuit gets tested and not just the visible part.
Do NOT reset any tripped breakers, which older installations in this area produce fairly regularly.

Common questions
How do you decide what actually needs doing?
By testing first. Same-hour NICEIC attendance is confirmed or ruled out with instruments before anything is quoted for the Caerphilly property.
Will the power be off for long?
Only for the parts that require isolation. We plan the sequence so the Caerphilly property is not dead all day.
What happens to old parts?
They are removed and disposed of correctly, and shown to you first if you want to see what failed.
Can two jobs be combined into one visit?
Usually. If you need something else doing at the same CF83 address, say so when booking and it is priced together.

Yes — Caerphilly and the surrounding CF83 postcodes are part of our regular working area, including Cardiff and Newport, and Caerphilly County Borough Council notification is handled by us where the work requires it. It is part of the quoted scope.
