I would avoid ikea, I went with them because I didn't think I had the time/expertise to manage lots of different contractors for all the things we needed (gas cooker opposite sides of kitchen currently, new cooker was all together, so need gas lines switching off, ripping up and replacing floor tilling, plastering, repairing damp, repositioning the sink was all involved), and also WHICH recommended them.
But I still managed on managing them and their subcontractors they use, like 5-10 hours a week calling and emailing, because they all refused to speak to each other.
A few weeks before work was about to start it all transpired it would be another 2 months before they even considered measuring the granite tops and cutting it, but the kitchen fitters wanted to knock my kicthen out to schedule.
Meaning 2 months without work tops.. flooring or wall finishings. And that is IF it went to plan.
I got all my money back (£12k) after kicking up a HUGE fuss.
Currently taking quotes from local small firms after gathering feedback on Facebook, local friends etc. So far so good.
WREN quoted me 16k
Ikea quoted me £12k
Local contractors quoting me 10k, plus pulling in some favours from tradesmen in the family.
