Some of the canisters (where you just screw them into a case and it pierces the top for a connection) are interchangeable, but the LP gas bottles have different fittings. Depending upon the type of connection you would need either an adapter or simply connect the hose to a British regulator and fitting.
Note that the connections on butane and propane cylinders here are also different froim each other, and different pressures are used so there are two different regulators.
