Firstly have you asked the fitter how much he thinks is a reasonable amount to be paid Once you have this information in writing with both an amount for labour and materials you can judge if you agree that this is reasonable Personally I would say that a cost of around £150 per day for labour is reasonable plus the cost of any materials You will have to agree an amount to be deducted for any work that was in your opinion unsatisfactory this could be a grey area to agree on I would say that it’s far easier if you can keep things on a professional and fair level without it escalating to a point where you both feel unhappy always best to talk things through with the tradesperson and try and come to an amicable agreement Good luck
