Thanks for the replies. Seems to be a difference of opinion.
I need plastering, new electric board, some gas pipe installation, floor etc and with the budget we have - modest - it seems that the most significant saving I can make, whilst keeping Mrs farfromthesun happy in terms of the look of the kitchen itself, is on the fitting which looks like being around £4k. With that saved and redeployed on the cabinets, doors, etc, it's a big difference. Cost to me? Time, and I'd better not screw it up.
(with apologies to OP, again)
