Can anyone tell what fitting the dupla regulators have and whether any
co2 cylinder in the UK will fit it?

I would have thought it would be the industry standard connection & if it is
the cheapest place to buy gas is your local Calor Gas depot.

3.5Kg bottle for £15, no deposit, no need to buy a bottle - just take it
back & ask for another one when its empty.

I.
