we had a new ceiling put in, as well as massive brick cupboards removed. also new sockets and lighting which upped the labour costs
we got our kitchen units and sink etc from howdens, just picked them from a catalogue and hoped for the best and it turned out v well imho
this shows the vibe of it:
bought appliances separately (fridge/freezer, washing machine, oven, hob, extractor) and had the builder install them
