Anyone got a link to a definitive guide to what we are allowed to work on with addition elements to our acs?. I did the lpg last week which was something like conglpg1 with permanent dwellings, fixed leisure accomodation, residential park homes and something else. I'm just curious as someone has just asked me to put heating on a boat....is this another element or is it included in fixed leisure?. Also I presume that all the additional elements in ng are now transferred over to be covered on lpg aswell? (wau, cen, wtr, lei, ckr etc, etc)
