I just asked him about filled up bottles by HP and he said I can do that but if something will happened I won't take responsibility because this shop don't have licence to fill up USA bottles.
But anyway thanks for replay and point where can I fill up my HP
Double check the markings on your cylinder, because if it is a US bottle then Landford won't fill it
The international standards to look for are:
DOT - USA department of transport
TC - Transport Canada
Pi # symbol (The squiggly Pi) - European TPED regulations
Check the UKPSF HPA1 for more info:

I used APS Marine to arrange hydro test once. The first guy I asked was very happy to arrange it for a paintball cylinder (but said it would be some time as they would send dive bottles in batches, no problem)
When I returned to collect it he was even happier as while it was sat in the shop many divers were commenting on it as a good size for a miniature pony dive cylinder, and I had offers to buy it. (I didn't want to, but he possibly gained some sales on new paintball cylinders)
They had also filled my cylinder, and it was USA manufactured but to TPED European approved standard
As I had got a good test price a little later I returned to ask for a price on testing a batch of aluminium cylinders. This time i spoke to a different guy who was unfriendly to paintball and given a ridiculous price to get rid of me
This may be some ignorance about your cylinder thinking USA manufacture means it is a US only bottle (but cylinder standards should be easily recognised by a dive shop). Or they may be right and it isn't to European standard
