Burning smell from the fuse box in Merthyr Tydfil? Step-by-step safety guide and same-hour NICEIC attendance.

Every enquiry we take from Merthyr Tydfil starts in the same place: what is the installation actually doing right now? Photographs of anything hidden are taken as standard, because you should not have to take our word for what is above the ceiling. Most Merthyr Tydfil visits settle this within the first hour.

What's different about Merthyr Tydfil

That detail is easy to verify.

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. It goes on the report.
