We bought our kitchen from diykitchens online. It was £3750 for units, £2000 worktop, £1500 appliances (oven, hob, fr/frz), £100 handles and £650 for fitting so about £8000 total. We have a straight run and an island so it was easy enough for us to plan layout. Our builder installed it for £650 as the units actually come assembled, doors on too!
Visit kitchen showrooms/designers and come up with a layout that works for you.
