Ours was done last year by a local kitchen company who fitted a kitchen from 'Lochanna Kitchens'. It's called Kashmir Gloss. Their kitchens come with soft-close doors fitted as standard. We paid a total of £7k for the units and fitting, which including building a small stud wall, some new flooring, some plastering and lighting as well as a cheaper set of replacement doors for the utility room. We spent anothe £1k on a cooker and dishwasher.
As for a tip - A wide pan drawer is an excellent thing to have. Ours is near the dishwasher and swallows up just everything that comes out of it every day. It makes unloading it a 2 minute job.
We also go a 5-burner hob with the wok burner on the outside of the hob rather than the middle. This means you can have a large pot on there as well as 4 other pots on the go, which you can't do with the hobs which have their hot burner in the middle.
We didn't get a boiling water tap but instead bought a Breville instant water-boiler for £70. It's excellent at giving you a hot coffee in less than a minute and way cheaper than fitting in a tap.
Just another note about a budget kitchen. In my photo I have a glass table and 6 leather chairs. We didn't have a table and chairs in the kitchen before and there wasn't much left in the budget to buy them so I took to Gumtree.
I got the Habitat oak and glass table for £60 and the 6 chairs in perfect condition for £90. They were 3 years old and had been bought for £750 (we saw the receipt). Both came from immaculate homes.
This is ours when it was almost completed 2 years ago. It is by Benchmarx and came in at just over 7k, including the integrated stuff, but not including the cooker. I was very pleased with the price. It now had proper flooring and a table and chairs, obviously, but I haven't got a decent pic. of that!
