Thank you all for the replies, especially the in depth reply from Colour Republic.
It's safe to say I'm now in a complete quandary. If anyone read my intro post it says I'm getting a kitchen put in while my hubby is away, I am determined to get this right and thought I was on the right tracks, how wrong was I (please be gentle with the replies lol)
First off Howdens doors only come in 2 thicknesses, 16 and 18mm ! I did ask the salesman the difference and he did say it was only the grip, I suppose common sense should have told me that the j style doors weakest point would be at the top, and as you've correctly pointed out, the thickness of the doors does indeed matter - a lot !!
I'm at the stage where my ceiling has been taken back to the rafters, a new one went up today. All my tiles are off with a plasterer coming tomorrow, all wall and base units are stripped out, so I've already had almost a week of living with just one very small worktop between my hob and sink. The joiner is booked to start work on Monday as I had "almost" settled on the howdens kitchen (before I read the replies) to this post, however I have not signed anything yet, I'm led to believe that howdens have everything in stock but I'm not sure if cancelling a verbal contract with the joiner would create any problems ie will the joiner have put my order in for me already ?
There's no question of me cancelling the joiner so as far as I can see it would just mean he's not doing the job for approx a month, or am I missing anything obvious?
1 last question, which could save the day for me (time wise) as I really don't fancy living in the conditions I'm in at the minute - I got a quote from B&Q for the glossy white Cooke and Lewis units. (Appleby) B&Q assured me that the carcass on this range is not the Cheaper IT carcasses, I have a complete breakdown of prices and I have been quoted for the "uniclic" carcass. I was told these door are solid wood base and lacquered, they went to great lengths as to the quality, and I must admit out of all the places I've looked at these did appear glossier, but for the life of me I can't remember how thick they were, can anyone enlighten me ? The price for this is £200 cheaper than howdens, so it's coming in at the same price as DIY K, as I'm typing this out I think I'm answering my own question, does it look like im paying more to howdens but getting less quality doors?
The only reason I had against B&Q was simply they're reputation when compared against howdens, plus I would say the joiner swayed me a bit by pointing out how easily it is to chop and change things with howdens should they be damaged, which I appreciate is a massive advantage both for the joiner and customer for completion.
I think what I'm now asking is howdens versus B&Q as it's pretty obvious that I should be patient and wait a month or so and order online and hope nothing comes damaged.
Soz for such a long winded post but I have a lot of decision making to do between now and tomorrow.
Edit, Soz although I haven't acknowledged your explanation about lacquer and PEP doors, I think I've understood it in (blondeness terms lol) PEP and foil wrap doors are basically just a kind of covering and glossed over ? And lacquered is superior as its painted first ? - I did warn in my intro post I'd ask a lot of stupid Q's
