Keep in mind that some firms will not fill or exchange tanks where direct ownership is in question. i.e. too many stolen tanks!
The other issue is when was the tank last static tested. If out of date some firms require testing prior to refilling at an extra cost. Others will just about take anything.
Some will refill an owner owned tank that is currently certified, but may take some time for that to happen. No in and out type of scenario.
It would be best to check with oxygen suppliers to see what their policies are. Of course, purchasing a "new" tank from the supply firm is an option but costly.
