As above 3 brackets minimum manufacturered by vokera and fitted as MI straighten the flue up repair the roof felt where it passes through the roof . Kop
 
Also had two Gas Safe inspectors just recently tell me the same thing, Strapping is not allowed and has to be a proper flue clip on every length of pipe. We've always used clips anyway as I hate the strapping so didn't matter, but i've seen many that have been strapped.

My view is that if you go to a job that's old and it's strapped and adequately supported & secure then it's fine. But on any new installations they should be flue clips.

Getting back to the OP, needs 3 clips on that flue.
 
No strapping it must be a proper manufacturerd bracket fit for purpose , 4 on this Intergas flue . Tkop

The flue runs up from the boiler into the attic. There are then two 45 degree elbows before the flue runs out to the rroof.The flue runs parallel from the boiler to the bit going out of the roof with an angled bit in-between. Where by regs should the brackets go and how many will be needed?

A clip at every joint and where it exits would do it
 
I always just put on what ever I've been given so baxi supply 1 per length plus 1 for the vertical terminal so I'd put 3 on that if it still feels loose I'd chuck another on.

I always thought it had to be 1 per length and every change of direction but I have no idea where that came from so don't quote me on that as I may of just dreamt that.

And I also thought you couldn't use banding anymore. Was told that by a bg inspector when I subbed to them years ago and also by the gas safe inspector when he saw it on the van.
 
I was always under the assumption manufacturers requirements overrule regs. This is only what I've been told though, probably the same as others. @firemant can you put a link to either prove your statement or disprove HF's?

HaHa. I was waiting for that, and I will. But I am not at home at the moment.

But, for now, a Regulation is exactly that.. And is part of Law. That is not to be confused with Standards, which are not. A manufacturer, or,indeed an engineer, can use a method not in the Standards - but may be called upon to explain why their methodology is as or more apt.
