Moving a boiler into internal hallway?

[PinkElephants79]

DP and I recently bought our first flat and the boiler is currently in the (only) bedroom. We’d ideally like to move it for noise/space reasons, but not sure if this is possible

It’s on an internal wall with the flue going through the adjacent external wall. There’s a cupboard in the hallway directly outside the bedroom door where the boiler clearly used to be housed - on the same internal wall with a hole cut for the flue to exit through the ceiling and then roof.

Would relocating it back into this cupboard be against current regulations? We suspect it was moved as the hallway is entirely internal and it should be against an external wall but not been able to confirm this

I know there are rules about where boilers should be if you want to rent out a property.

The flue has to be easily inspectable along its length. This is easy if it's on an external wall, but not so easy if it's internal, especially if it goes through other people's flats.

Why not get a qualified boiler engineer round to give advice.

The flat was previously a rental, so that makes sense. We want to put wardrobes along the wall the boiler is on and if the boiler was in the hallway the flue would either need to go behind the wardrobes or through the roof which should in theory be okay - I’ve just found a lot of conflicting information online about whether this would work in practice or not

We did have a boiler engineer round to do a service but unfortunately he could only come whilst we were away so didn’t get a chance to ask advice and booking in another visit is proving difficult!

I don’t think there is any difference regarding where a boiler is sited in a rented or owner occupied flat. However now all new boilers must be condensing boilers which restricts the the length/type of flue and it’s external location. Also the condensate needs to go into an internal or external drain,

You'll probably find the kitchen or possibly the bathroom are your only options if they have external walls.

Unfortunately the bathroom is too small to have the boiler there with enough clearance for the bath and shower and the kitchen is under the eaves with very little wall space.
