If you are anywhere near Leeds, go to the DIY-Kitchens showroom, it's great. I liked their kitchens & a lovely MNer let me go to her house to see hers installed 😊 Unfortunately due to the shape & size of my kitchen I need a drawer size they don't make. Typical.
I loved the Wr/en kitchens, but after reading the customer sevice reviews & then the thread they participated on here, I wouldn't touch them with a barge pole.
Ikea doesn't work for me because all our pipes go along the main wall and Ikea units don't have a 'service area' (space behind the back of the cupboard) and the u shape of the kitchen is too tight to just put the units in front of the pipes) & it would be to much work to make cut outs for all the pipes & I don't want them in the cupboards anyway.
I think Howdens & Benchmark are much of a much, each doing the odd thing better than the other.
Look at Wicks showroom, buy from Benchmark.
One of the builders I spoke to said he thinks Cook & Lewis from B&Q is a good option, just not their budget range.
I've had NO luck with 'local kitchen companies' but lots of others on here have, I suppose it depends where you live.
Budget - how long is a bit of string? I think Benchmark are quite good value & whichever one you go with, it's the 'bits' that cost the money, do think carefully about what you need v want - then, think about how much benefit or pleasure you'll get out of your kitchen if it's nice to use. For example I wouldn't compromise on GOOD self closing hinges or a GOOD tap, but I'm considering a laminate worktop because they're inexpensive and pretty hard wearing - whereas the the worktop I'd reality like would be £3,000 & I can't justify it in this house when we will probably rent it out.
Appliances - mine all need replacing anyway, but if they didn't I wouldn't replace them if they fitted where I wanted them to go, but I would if it was restricting my layout. For example I'm taking out an undercounter fridge & putting in a full size frudge freezer and I'd do that even if the fridge didn't need replacing. The only thing I'm dithering about is the washing machine, but there's no 'unit' for that, so I'm going to order an extra door & decide later.
