There are to many factors involved when estimating.
Kitchen design, materials, fittings and more...all playing it's role in price.
Such size kitchen furniture can start from roughly 4k and if higher end then can be around 6k
Worktops: Laminate? Wood or stone? It could be up to 1k if laminate
or roughly 3-5k if quartz or granite...
Fitting: very basic (not involving electrics, plumbing, splash backs etc) would easily start from around 600-800
This brings us to a very rounded and rough estimate of roughly £8000...it doesn't mean it couldn't be less...and plenty of options to have a luxury kitchen option costing you more...
