If I could give 0 star I would. Customer service rubbish. Quality of work absolutely poor. I have holes in my kitchen which let air in which were supposed to be sealed before fitting my washing machine! There’s a 5cm gap above my dishwasher, not to mentioned 3 holes drilled incorrectly through a cupboard to let the sink waste pipe out (clearly the fitters couldn’t get their calculations correct on where to drill a hole for a pipe, so they punched 3!) my extractor fan sounds like a jumbo jet as they sealant wasn’t done correctly. That’s just the beginning, I see my kitchen everyday and think I wish I had never used Wren! Don’t do it!
