End of the story?
Just realised that I haven't completed the story of the kitchen....
Well, after the last entry, we finally DID get a Corgi certificate for the cooker installation. We also made sure we had an electrical installation certificate for the kitchen electrics.
About a year after the kitchen was installed, we called KK to report problems with dropping cupboard doors (to be expected, I guess; we had a couple of corner cupboards with big split doors). To their credit KK sent out a fitter to fix the problems (replaced the wonky hinges).
On the down-side, we did not get any feedback to our comments / feedback / complaints to Graham (the MD).... as he said in one of his conversations with my wife - he has other people to deal with complaints!
We got our own man in to do the tiling - looks superb.
We had to get KK back early on after the installation to fix leaks on the sink waste pipes - sadly somewhere along the line the glaze in the sink has been abraded, so we now have a couple of marks around the waste pipes that keep reappearing.
We chose drawer handles that hinge downwards & knock on the drawer fronts - so within a year we now have marks on the drawer fronts.
Overall, I suspect that the units will be looking worse for wear within a year or two... but we shall see.
