LPG Pipe Installation Caravan Catering

Good morning all what a great website this is!
Apologies if this question has already been asked but couldn't find it if it has,

I'm refitting a trailer and as usual, space is at a premium, is it legal for gas pipes to come in and out of the floor to reach appliances? To be clipped under the chassis? I understand this is normal practice on some caravans and motorhome but unsure in trailers

This trailer will be static if that makes any difference.

Many thanks

Felix
