LPG pipe routing

[gordonspants]

A quick question for any LPG qualified engineers - proposed bulk tanks in an approved location, but LPG boiler to be sited 20 metres away in the opposite end of a house.
Can the LPG supply pipe from tank to boiler be routed in the loft?
Clipping it to the wall outside is going to look ugly, and trenches are virtually impossible due to gardens and drains.
Can the pipe go up the wall and inside the house at eaves height, then along inside the loft and down to the boiler, either completely internal or popping back out and down the wall so it's not routed in a habitable space down from loft to boiler?
LPG supplier not confirmed yet - house refurb, and waaaaay off ordering a boiler etc - basically is internal routing acceptable?
Many thanks

sorry not quite sure what you mean, but from the bulk tank to the house will be in plastic, this will be run underground to the external wall of your house where there will be an emergency valve and test point. From here, you can pretty much run as you would with NG pipework, but you will still need to get up to the loft ? up the outside of the wall? If thats what you mean then yes its ok.

Hi, thanks for the reply.
The tank will be 1.5m or 3m from a garage wall, the garage being attached to one end of the house. So pipework there will still be above ground.
We can't go underground beyond that anyway - too many obstructions.
Pipe has to be either surface mounted all the way around the house wall, or hopefully it can enter the house at one end near the tank, go up into the loft and along the loft then back down to the boiler roughly 20m from the tank.
If regs state the emergency valve has to be where the pipe first enters the building, then the valve can be externally mounted at the 'tank end' of the house before the pipe enters the property.
Is it steel pipe they use for above ground work?
Cheers

are you sure the pipework will be installed above ground from the tank? Every install I have seen or had anything to do with has had buried pipework up to the point where it meets the building. Even very short distances. If it is above ground then yes it will be in steel.

yes that sounds about right
