Just putting this down in case anyone is looking at installing/upgrading a DIY kitchen. We have used the below and were impressed with quality/price/service:
https://kitchenandbedroomdoors.co.uk/ we bought white gloss slab doors. Six years on they are still going strong. We now need to add some new doors (doing some changes) and I was pleased to find the same model is available.
https://www.kitchenfittingsdirect.com/gb we got our pull out baskets from here. Just bought some more. Straightforward to fit and the ones we bought 6 years ago are still just fine.
https://www.stainlessdirectuk.com/ just bought an infill panel and now thinking about stainless steel worktops.
BTW I'm not employed by the above just wanted to give a recommendation!
