Last week I had a new combo boiler installed, guy who owns the company did the quote but another guy came and did the work. All fine, new boiler is great, however while he was here he said that the bathroom sink tap needed replacing as the water had all come out of the top of it when it was connected up due to the pressure. He said they would come back this week and sort it.
Owner guy came round just before he had finished, checked his work and said to me that I would need to get a plumber round to sort the bathroom tap. A bit later he said that he'd spoken to the other guy and they would call me this week to come back and sort the tap.
Today he called and the other guy came round and did the tap. All good. However tonight I have had an invoice for £90 - £45 for the tap, £30 for labour and £15 for VAT. I assumed it would be included as part of the original job, even though it wasn't in that quote there was nothing wrong with the tap before they did the work? I suppose I shouldn't expect them to pay for the new tap etc but I wasn't given a quote and I thought they were doing the work as part of the original job?
YABU - its a different job, pay up
YANBU - its part of the job I have already paid for
