Baz ........ perhaps I should add (for Annoyed's benefit as well) ...... Apart from early kitchens, many years ago, there is no argument over the quality and value for money offered by B&Q units. It's just a standard "joke" in the business about B&Q's missing items, especially the units they never seem to have in stock, but arrive weeks later.
A lot of the Stores, perhaps most, have their kitchens made and supplied by Howden's. At that end of the market, there is no difference in quality, only available styles.
For every complaint over B&Q, I guess there are many people who have had a good, trouble-free service. It's just the incidence of inadequate stocking; poor customer relations; poor organisation etc that crop up far too often.
Of course it's always something of a "lottery" dealing with anyone in trade. Builders often being among the most problematic, I have to say.
Just a personal opinion, but look at Howden's website. I've heard good things about Magnet as well.
My biggest (pleasurable) surprise was when I fitted an Ikea kitchen. Scandinavian efficiency. Every little component supplied. Every fitting etc etc. I like their styles too. A little groovier than the standard Store items.
My biggest recommendation would be to measure and identify each unit in your layout yourself (I'm sorry that's no help to you now Annoyed.)
Take the trouble to design your own layout.
When the Revolution comes .............. the first to the wall shall be inhouse kitchen "designers"; "surveyors"; "consultants". Last week they were probably tyre fitters ;o)
