£45 to change a tap is cheap as anyway ha ha! some people are unrealMy plumber just had a similar problem, his customer had seen a £100 tap and that's the one he was going to get, plumber quotes £45 for changing tap and customer accepts. Plumber turns up to do job and customer saw another tap that cost only £35 and now wants a reduction in fitting costs pro rata with cost of tap. One word, idiot!
