I recommend Howdens, look up your local showroom and obtain a brochure, then request that you have a plan drawn up. As they only sell to the trade, you will have to get a kitchen fitter to get a price for the complete job. (They get a big discount from them) (Howdens should be able to recommend) I have found their units to be well built , good quality and a good choice,of colours etc. the bare units come built saving the fitter a lot of time. As a guide rough costs of kitchen fitter in SE England £200 perday
