My brother is in the trade and has told me to go to Howdens get them to quote, if they will give me their trade discount without the hassle of his company ordering then great, if not then he will order the bits for me and invoice me directly.
His general recommendations were to get the kitchen units from Howdens, the tops from somewhere else as I can probably get a better deal.
Get a joiner to fit the tops properly and do the rest myself.
oh and to fit soft close kits and posh taps to cheap sinks. Apparantely the women come into houses when looking to buy open and close the drawers and see the soft close, cream themselves, then notice the posh taps, and ignore the cheap sink.
