...................., the ring is supposed to be evenly loaded, but all they
have done is run the ring round the ceiling joists on the ground floor
pulling it up to the bedrooms and down to the other rooms. As the CU is in
the garage, and the first stop on the ring is the kitchen the ring is
massivly unbalanced!

As the Currant Bun says, "gotcha!" The unbalanced loading on the ring
strikes me as a clear violation of good design practice, and is *specifically*
mentioned on the page of the OSG wot I quoted (and the note in the margin
traces back to reg 433-02-04). I think it's time to put your concerns in
writing: a *short* letter - try to keep it down to 1 page of A4 - saying
you believe the design of the electrical installation to be inadequate for
normal pattern of occupation (don't say "I'm a gadget freak", just say
"dushwush, washmash, tumble-drumble" (or rather the more common forms
of the names for those appliances!) and other kitchen appliances, plus
normal appliances upstairs, make overheating of shorter leg of run to
kitchen a foreseeable hazard.

(Also, if the cabling goes up and down between ground and first floors
repeatedly in the way you mention, its total length may be getting
close to the limits for a 30A/32A 2.5mmsq ring - 88/84m resp. for a
normal Type B MCB: and that hacked design contributes materially to the
unbalanced loading of the legs of the ring feeding the kitchen. The
conventional design of an upstairs ring which would go up once, feed
bedroom etc. sockets, and then come down, would be much more appropriate.)

Ask for a response in writing. Have you paid for the house yet? Can you
retain money for (a) getting an independent inspection, and (b) rectifying?
Make it clear you're questioning the design of the electrics in *all* the
houses slapped up to this design, not some wacko requirements which your
own current-consumption-obsession produces ;-) If you do want to pursue
this you will need a qualified electrical installation designer's opinion
to put up against theirsr. If you can face the investment of time and energy,
you might find that one of the medium-sized local companies in your area
would be happy to do this as a 50-quid inspection-cert job and throw in
a couple-of-para amplifying letter as a way of venting their frustration
at being undercut by whichever cabling-cowboy got the contract for this
build ;-)

Only you can judge, of course, whether it's worth your while raising this
amount of stink with the developers, or whether to shrug your shoulders and
prepare for a wiring upgrade as you move in.

Good luck with whatever you decide - Stefek
