Only manufactures that stipulate the flue joints must be screwed are classified as AR. A lot of the flues, the manufactures instructions do not state that screws must be used. Manufacture instruction is the correct way to install and if you have them then you don't go by the gas regs if they contradict. I had this issue a few weeks back, service engineer AR'd a Greenstar 24i JNR for not having screws in the flue clamps. Yet in the installation instructions it does not state that they are required. I rang technical and they conformed they are not required. Yet Vaillant say screws must be fitted. So go by the M.I.s and AR it if it's different, although I wouldn't necessarily AR a boiler fitted with screws if they weren't required.

A common sense answer, cheers Arran!

This is another subject that should be plainly explained by Gas Safe, but we engineers are as always left in limbo.
Not good enough imo.
