I recently bought a kitchedn from B&Q, very happy with the purchase. I got the IT range with solid oak doors, price worked out well. Approx 7m of lowl level units (inc 1 x corner unit & soft close drawer unit)handles, plinths, 1.5 sink (no tap), integrated dishwasher, worktop (not granite or solid wood), 3m of eye level units, pelmits & cornices all for €3145. Fitted this myself and didn't have any major problem, numerous minor ones but with my level of DIY experience that was to be expected. TBH it would be impossible for anybody else to tell whether it was self fitted or not.
B&Q had a kitchen design service with a really good designer whom I just brought my dimensions to and she gave me the qoutation with a computer generated picture of what the kitchen would look like.
Very impressed overall (no affilliation to B&Q)
