Among the other questions I posed to my local building dept. I asked about mobile homes as well. Here's North Norfolk's interpretation of it:
Quote
Regarding mobile homes, if they fall within the definition of a caravan under the 1960 or 1968 Acts, then they are exempt from the control of the Building Regulations including any associated electrical work.
The 1960/1968 acts allow quite generous sizes for a caravan to still be classed as such (about 60 by 20 ft. if I recall correctly), so most double-wide "park homes" are clearly included.

So there you have it: If you want to still be able to legally carry out DIY wiring without notification and inspection, move to a trailer park! [Linked Image]
