Hi. Can a horizontal 200A consumer unit be fitted vertically, or is there a vertical configuration? I have a 350mm wide space...thanks.
 
Its a 3.5 bed/ 1 living room/1 bath/kitchen/1Wc house.
the chances it needs a 200 amp supply allowing for diversity is almost impossible in a normal sized house which from your description this must be, anyhow you will not get bigger than a 100 amp single phase supply anywhere and if you want 3 phase there will be questions that have to be answered. I have a feeling we are dealing with an inexperienced electrician who has added up all the MCB sizes and got close to 200, it doesn't work that way, I very much doubt you will hit 80 amps, even with an electric hob, oven and shower.
 
If the consumer unit doesn't fit the intended space then put it somewhere else either direct to the mains or indirect by way of a switch-fuse if required. It is highly unlikely a dwelling of that size needs 200A and a dual RCD board is not the way forward. This has all the hallmarks of a builder's microscopic knowledge on any subject put before them so seek the advise of a competent independent electrician.

I've a (large, with private water treatment, ground source heating, workshops....) house I built in Devon many years ago - by the 'add it all up' principle I think from memory it was well into the 5-600's. By diversity this fell to something like 350A. It's been sat on a 100A fuse (nb, with full knowledge of the local DNO engineer as we had to get a pole TX installed for it) since forever with zero ill effects at all.
