There's a strange dull, smokey odour coming in waves, every couple of minutes, from the fuse box in the house. It's situated in the living room next to the sofa, so when sitting next to it I get the smell every couple of minutes. It's not very strong but it is noticeable, and began a couple of weeks ago.
It was only today that I really tried to find out where the smell is coming from, and I realised that it's coming from the fuse box. I figure the best thing to do is get an electrician to take a look at it a.s.a.p.
Any ideas what this could be? Should I get an electrician to look at it right now, as in pay for a 24-hour electrician to come out? Also, what do electricians charge these days for call-outs?
