Came across a flue in void, inspection hatches fitted to standard, flue was solid and rigid, joints screwed, but no supports. Boss who was with me seems to think this is AR as its in a void but only NCS if it wasn't in a void. Is he right?

did they change it as my last re up was ncs? and didnt get any emails like i normally do
Yeah AR if no hatches. I just found it strange that because it was in a void it made it AR, but if it wasn't only NCS. To be honest there is less chance of flue being knocked whilst it's in a void, as the joints were screwed and was completely rigid, there's very little chance of it coming apart or being damaged by 3rd party.

The thought behind it being if the flue failed in a void you would be less likely to realise thus causing more risk to life.
Yeah true, although must admit I don't agree with the "ruling" on this situation. If you had any doubts about a flue failing in a void or out, it should be at least AR'D anyway, if it is secure, screwed and in a void where it can't be damaged, I find this less of a danger than in a loft where it can be easily knocked etc, but hey ho I don't make the rules haha

hopefully when they release the new system things will be more defined and they will stop changing things 😀 well we can all hope cant we
Absolute rubbish!!
General standard is should be supported every 1.8M or and change of direction. (unless MI's specify differently) No difference wither in void or not!
If flue not supported as above then your call to AR or NCS it.
Generally if only maybe one joint and flue screwed, no supports but solid I would NCS.

when doing a 90 and then going through the roof you need one to support the 90 and one to support the other end

The FIV rules have nothing to do with damage being caused or otherwise. We are required to inspect the length of the flue, and this cannot be done in a duct. The hatches are to enable us to meet our obligations.
There are plenty of failed flue joints - not necessarily as a result of mechanical damage

Flues must be supported at 1.8m or every change in direction before and after the bend. Unless the manufacturers instructions suggest otherwise.
Baxi for example, state that the flue must be supported at least every meter and before and after every change in direction, preferably supported on every section regardless of length. I fit them at every meter, depending on how rigid the flue actually is I may fit one on every section. Having said that, sometimes you physically can't get a clip on each section. In this case, there's not really much choice, you can't do the impossible.
