Are there building regs about the use of different kinds of plasterboard in the home? I want a partition wall with kitchen on one side and bathroom on the other. The bath will sit against it. Do building regs even apply for internal partition wall construction/rearrangement?
TIA

Only if it's load-bearing or where there needs to be fire resistance between two areas. But even then there are no regulations governing the type of plasterboard to be used.

Specifically, for half-hour fire protection you must use a double layer of 12.5mm board or a single layer of 12.5mm fire check board

Does the fire protection rule apply for the circumstance I mention? How does one decide?

If the kitchen and bathroom are both in the same dwelling and neither of them are a protected escape route then no fire separation is needed. If this applies to you and you're building a new partition, use 100 x 50 vertical studs at 400mm centres for best rigidity (unless you're really short of space then use 75 x
50). Fill with fibreglass quilt insulation or better still Rockwool batts. Use one or more layers 12.5mm square edge wallboard each side, finished with plaster skim. Taping and jointing is only for Barrett Homes, not proper tradesmen. :o)British Gypsum White Book
The answer is yes, as long as there's no door between the two rooms; (and in this case I would assume there isn't). Since last July Part E, specifically Regulation E2, applies to ensure a reasonable level of sound insulation between rooms within a property. It's the weight of the plasterboard (or really mass per m2) that's of concern, and now you can get soundblock plasterboard which is ok if you use 12.5mm each side. Otherwise could need a double 12.5mm layer of normal pb each side.
