I got new kitchen from Wickes 8 years ago using their fitters. There were a few issues at the time of fitting that got escalated to Wickes but they got resolved or so I thought
Dishwasher has broken, on pulling it out I realised they must have forced the sink on top of the freestanding dishwasher when they were putting it in place and now I've broke the sink seal and can not slide the dishwasher back in due to sink fitting. When fitting the sink Wickes did acknowledge there were sizing issues on their side not mine but they could sort it
John Lewis arrived this morning and refused to fit new dishwasher. I need new isolation tap (my issue to solve) but even if I fix that they still wouldn’t fit it due to plug being directly underneath the tap
They said although no regulations for kitchens like in bathrooms it was so dangerous they wouldn’t fit it
YABU it's been 8 years suck it up and fix the 3 issues yourself
YANBU to expect Wickes to sort out the plug and sink issues
