I had some work done on my house. The quote was sent through via email. It was just a few lines specifying the work required and then said price: £X
I’ve just paid the bill and had a message saying they haven’t received the full amount, that the quote was for £X + VAT.
There was no mention of the VAT on the quote or on any discussions we had about the price.
As an aside, we had a few disagreements during the work because I refused to take him up on the offer of additional jobs he decided needed doing.
