We have a good electrician who we have worked with for about five years but recently something happened that had left me pretty annoyed. I asked our electrician to come by to move a plug socket in the kitchen fairly urgently. He came the following week. We hadn’t agreed a price. I was at home but upstairs with our tiny baby pretty much the whole time. He turned up with another electrician and my understanding is that they installed the plug very quickly, perhaps within an hour. My husband was liaising with the electricians. It turns out that rather than leaving when they had done the plug they asked him if there were any more jobs that needed doing while they were there. They ended up moving some light switches and installing some lamps. I then got an invoice for £600. I queried this with the electrician and he said he billed me for two electricians for a whole day. I am upset about this as I feel taken advantage of. I wasn’t available on the day yet I am the one who is now expected to pay for all of this, and ultimately I only asked for a plug socket to be installed which took one person less than an hour. I really think it’s unreasonable to be slammed for an invoice for £600 and that the electrician has kind of taken advantage of a chaotic post-baby household. What should I do?
