Thanks for your response. Is there a way for me to find out if he has assets? I looked at small claims court and dividing the issues, but I read somewhere (maybe citizens advice or GOV. website?!) that you cannot claim against the same person twice for matters arising from the same incident so I'm not sure that it would work out as surely it would be seen that these issues have all arisen from the same incident (his original work)?

@BankFodder I have obtained 3x independent Quotes, the average of the quotes was 24,000 including VAT but not including things like sanitary ware if that is damaged trying to rectify his works or new tiles. In addition I have already spent £1000 and anticipate needing temporary accommodation for at least 1month but it is hard to know how long the works will take.

Thank you for your very quick response. I am asking for (almost) a full refund, in that I am asking for monies paid to him ( I paid over this due to directly paying for certain materials eg steel beams, planning applications, engineering calcs and drawings etc) however, I anticipate that I won't get the full refund and am realistic about this.
