You are being fobbed off, and I suspect the furniture ombudsman will be a waste of time. When you pay top dollar you expect and are entitled to a perfect job. This isn't. What I suggest you do is go to another kitchen fitter/professional joiner and get a quote to put it all right. Then go back to wren and tell them the kitchen is not fit for purpose or of satisfactory quality and give them one opportunity to sort it out. Tell them if they fail to correct the faults, you will get the work done by others and then use the small claims court to claim damages from them. You are entitled to be reimbursed for the cost of the remedial work, so you will have to pay out to get it sorted first and then use the invoice as the basis for your claim. https://www.citizensadvice.org.uk/l...gal-action/small-claims/making-a-small-claim/ https://www.which.co.uk/consumer-rights/advice/how-to-complain-if-youre-unhappy-with-building-work You have a pretty solid case, because that is demonstrably shoddy workmanship.
