room sealed flue in brickwork/void

[Dan83]

Hi all
I've been searching for clarification on this and cant find it, I'll prob end up ringing gas safe but here goes anyway!
got to service a boiler r/s on monday and as i know the property I know the flue runs into what looks like boxing, maybe about a meter then terminates on the outside wall, I mentioned to the home owner new regs re flues in voids, but he has told me the home builders, (its a newish estate i.e under warranty) have sent letters round saying the flues in voids is not applicable as the flue is in brick, lined with plasterboard. so I assume not in a void??

my question is basically this, is the ruling due to the void or because the full flue length cant be inspected
I thought it was the latter but I don't want to start slapping AR on boilers for no reason?

I'm assuming there must be a join in that run somewhere also which obviously makes it an important factor.

Might be me being unfair but I'm taking the info on his letter from the builders with a pinch of salt because if this is a problem someones pocket is going to take a big hit!

looking forward to any pearls of wisdom,

thanks Dan

AR until proved otherwise, its a flue and its in a void not a chimmney

Thanks mate thats what My instincts are telling me just that element of doubt, was creeping in!

Is there a joint which cannot be seen, then it needs access.

Yep needs inspection for me as stated its a flue built in cant see it, a-r for me

Read note 2 on tb008, do a risk assessment and make your engineering judgement.

does it need acces if its one length but then how do you prove its one length i say this because i notice longer lengths of flue(2m) appearing on some boilers extras lists. Years ago with non condensing you could get 3m lengths of concentric flue for some boilers

it needs inspected within the void. how do you know it does not have a set of bends in it, damaged, rotten, vandalised, or just ugly! but then it may be perfect and you did what you needed to do. the builders letter means nothing as your the decision maker on this. AR if working/reading good. ID if any bad signs. IMHO ta steve
