Yeah, I've just submitted the above plan to DIY kitchens, the current quote for the above (the plan is made from their website) is £7100 but they're running the free AEG dishwasher + cashback so should work out at £6500-ish for the above
Got the Howdens saleslady come round to mine last week, for a lesser spec (slimline dishwasher rather than full size, no integrated bin), Howdens asking for £9600
Both kitchens are in handle-less gloss white and laminated wood worktop...so a £3k (~50%) difference which is an extremely hard pill to swallow, both quotes not including fitting
My current builder that's doing my refurb at the moment is a Howdens partner so pushing quite hard for me to get Howdens, but even if he gives me a "discount" on the kitchen fitting, I can't see how it will make up a £3k difference in price
