Can anyone give me some advice on a situation I have with my building company? Have had a few issues with them recently (posted on here about them) which are now largely resolved. I'm at the stage where I need to make the next payment instalment with work provisionally scheduled to start next week. I paid the initial instalment (£5k) by credit card and wish to do the same for all subsequent instalments so that I can benefit from the additional protections that paying by CC provides. The company are now saying that I cannot pay by credit card but that if I absolutely insist, there will be a 3% charge. My understanding is that credit card surcharges were abolished in 2018 and so I have queried this. I have a contract with them which does not mention additional credit card charges and none were mentioned (or paid) when I made the initial payment. I am nervous about paying anything via bank transfer and want to pay by credit card but not pay the 3%. Is anyone familiar with this area of the law? Pretty sure they can't do this but when I've raised it with them, they won't budge. I wouldn't have entered into the contract had I not been able to pay by credit card.
