I want to line the cellar ceiling and hide all pipes, cables etc one of which is the gas to the CH boiler. Due to it's position it will be just above the false ceiling... is there a requirement to mark it's presence in some way??

TIA

There would be no requirement to mark the presence or route but if there
are any compression fittings that would be inacessable then that would be
a no no.

A gas tightness test on the whole system would be advisable before
completing the suspended ceiling.

Umm.. don't the gas regulations get a bit stuffy about gas pipes in
voids?

Yes. IIRC, if the void is larger than 0.1m^3, then it has to be
ventilated. The size of the vents depends on the volume of the
void, and the vents used must have their effective vent area
written on them and must not be able to be closed.

Not at all. The required ventilation ensures there is no stuffiness.

(I'll get my coat.)

Those were my thoughts too but I have seen a relatively recent pro
install with the gas feed passing across (through) an unventilated
floorspace between 2 storeys. I was surprised but don't know if it was
wrong or not.

Any install of a gas boiler (or a gas fire, gas cooker etc.) which isn't
on an external wall with an external feed is surely potentially going to
involve a gas pipe through a non-ventilated void?

The gas to our boiler in the airing cupboard which has a flue to the roof
certainly goes under the upstairs floor and that isn't a ventilated void.
