Is it time for the debate then as to how, exactly, you define a chamber and then get a handle on its size? I'm going to kick it off with a simple suggestion - and then wait to get shot down!
The size of a chamber is determined by the volume of the largest sphere that would fit inside it - and its a "chamber" (as distinct from a bedding, rift or tunnel) if the largest spheres in passages to either side (and/or above or below) are at least 50% smaller.

Andys, based on what most cave chambers are like, I reckon a hemisphere is probably a better simple shape to use. However the definition will need further work, as lots of chambers will have stal piercing into your shape, thereby dramatically reducing their ranking. Unless you don't include stal, which will need lots of clear definition also!
I know the large chamber 3D scanning team have been looking for ways of simply ranking them and finding it difficult to be fully objective.

From Wiki - "Calders Geo is an inlet in the western cliffs of Esha Ness in Northmavine on the island of Mainland, Shetland, Scotland. A cave on the north side of the geo has been measured at more than one and a half times the size of "The Frozen Deep", a chamber in Reservoir Hole under Cheddar Gorge in Somerset, potentially making it the largest natural chamber in Britain."

The Frozen Deep is the largest chamber that is not open directly to daylight. Other large chambers of this sort include Pridhamsleigh 2, Bishop's Palace, Big Chamber near the Entrance, GB Great Chamber and I am sure there are a plenty of others. The Shetland site is a sea cave. Of course this is my point of view.

The TLDR for this thread:
Mendip: GG's a Rock Shelter, Titan's a shaft, nothing in Wales counts so Frozen Deep wins by default
Everyone else: We're still not coming to Mendip
