We are going through this at the moment. We are going to go Ikea. They have a good planning service and will be around for a long time for spare parts etc. Also, and this is a big thing for me, you can actually budget for what you want, as the prices are transparent. None of the to and fro bs with salesman from wren, or having to go through a builder with Howdens
Yep, being able to cost things up with drawers versus cupboards was one of the attractions of Ikea for us and no 60% off if you buy this week only type rubbish that we found with other suppliers. They also do taller wall cabinets across all their range, a lot of other places only offered those sizes on their more expensive ranges. We had one door warp early on, and simply took it to the shop and swapped it there and then.
The only slightly annoying part for us was we got our Ikea kitchen just before they changed from Faktum to Metod which means getting interior fittings and replacements is not as straightforward. But that shouldn’t be an issue now.
Not arriving pre-built was an advantage for us as we could store it all in the lounge ahead of time :-)
Our worktops were also worktop express (Ikea didn’t do 3m solid wood lengths at the time)
