Thank you for your great suggstion. Your place is a major step in the right direction. I went today. It has a fabulous range, of cabinets and doors, much larger than magnet and howdens. The showroom is about 10x the size of a magnet one. A sample carcass is on display sat alongside those from competitors so you can see that the quality is at least as good as magnet trade and howdens
Taking my tall integrated fridge carcass as a comparator it is £100 inc vat there versus
Magnet 312
Howden 272
Screwfix 240
The ikea thing is much lower quality. A builder I know also says that ikea is also very hard (ie unforgiving in real world conditions)to fit
The guys in there are not very helpful, there is no design service. But the price says it all. There is no expensive branch network employing two designers in each branch, so the overheads of this lot will be massively lower. Also, it does not carry stock - you must wait three weeks for it to be manufactured.
But to save a load of haggling with dishonest folk, I can wait
There is also a perfectly good chippy just round the corner from where you enter the industrial estate.
