Just been checking up on the specifics of bottles- whats legal and what ain't...
This page is all about testing and refilling, from the UK's largest N2O supplier-

The interesting bits...
We can refill any cylinder of any size with any connection as long as it is within its test period and is EU (PED or TPED) Approved. Any EU approved cylinder will have a " n " mark on it, otherwise known as a pie mark.

(I'VE JUST RUNG THEM AND THIS DOES INCLUDE CO2 BOTTLES AND YES EVEN USED FIRE EXTIGUISHERS, PROVIDING THEY ARE APPROVED AS ABOVE)
At this time, all cylinders manufactured within the UK and Europe have TPED or PED approval meaning they ARE EU approved. NX and NOS Cylinders are not EU approved as they only conform to DOT standards, and SHOULD NOT be refilled within the EU.
U.S. DOT cylinders we're allowed to be imported into the UK using Multilateral Agreement M125 but clearly stating that they should be re-exported back to the states for re-filling, however as of June 2006 this agreement has now been extended to 2011 and renamed the M180.

Here's the interesting bit about Non-EU made bottles (Eg NOS)- ...
(4) When empty, the pressure receptacles shall not be refilled and shall be re-exported to the country of origin
We can Retest cylinders through our sister company Energas, at their retest facility in Bradford. Retest costs (£50 + P&P) and the cylinder will need to be stamped to indicate it has been tested.
Non EU Cylinders however cannot be retested or modified to EU spec.
Anyone using a NOS or other US-spec kit is on shaky legal ground!
