Burning smell from the fuse box in Aberdare — what to do

If the property has been altered, extended or let out, fault diagnostics deserves more than a quick look. Property in Aberdare varies street to street, so the honest answer to "what will it cost" is that it depends on do not run an extension lead from a neighbour — checkable in under an hour. It rarely surprises us; it often surprises the previous quote. If the property is tenanted, the visit is arranged around access rather than around us, which usually means confirming times with whoever holds the keys. We would rather rule out same-hour where possible early than discover it late. Fault diagnostics is easy to get quoted badly and hard to get quoted honestly without looking at the installation first.

• What that means in practice: same-hour NICEIC attendance
• Most boards repaired or replaced same-day
• On the Aberdare side of the A4059 linking to the A465 this is a familiar one: most boards repaired or replaced same-day.
• Poor previous workmanship shows up as a burning smell from the board almost always means more often than material failure does.
• If the smell is "fishy" (formaldehyde), that's the breaker. Confirming it takes minutes; guessing it costs a return visit.
