Check: this depends on what sort of bottle / valve you have. If you have a 'surface only' valve ... where the valve/gauge unit is fixed to the cylinder then your bottle needs testing every 5 years. If you have a dive cylinder where the valve/gauge unit can be removed from the bottle (this then leaves the bottle with just an on/off valve on it but no gauge or fill line to your rifle) then you have a dive cylinder that needs testing every 2.5 years. You cannot add a 'surface use only' sticker to a dive bottle and expect it to need testing every 5 years.
To find a test centre you could ask your local gunshop or google Dive Test Centres and you should find one. Or maybe someone on here will give details.
Cheers, Phil

I have a Hydrotech group2 breathing apparatus air bottle, the whole valve assembly can be removed. On their website they show the cylinders need a hydrostatic test every 5 years.
Airgun Cylinder Servicing | Hydrotech SCUBA Equipment & Airgun Charging Systems
Hydrotech offer airgun cylinder testing on steel & aluminium air cylinders including those manufactured by Webley & Scott. We are also approved to test light-weight composite cylinders.

If surface only the 1st test is 5 years from date of manufacture, not purchase. Date of manufacture is normally stamped on the shoulder of the bottle along with lots of other data.
Tank is stamped 2018 03, lol.
Took it to this place in Leicester yesterday, it will take 10 days or so, 48 squids which seems resonable.
Em said if I don't pick it up she will hold my tank hostage with a divers knife and send me the pictures, not being a diver myself I think that's divers humour, are they all like that?

Did you ask them their policy if it fails?...some places will destroy, others will mark so any further (legal and above board) place filling will refuse, some places return, or at least that was the case a few years ago when we last had a mass test of maybe 20 bottles held at work.

It's my first time so I never knew the pitfalls, anyway got it back yesterday and it's good for another 5 years, they filled it to 260 bar, what bar do gun shops fill to?

Whatever the tank is rated to? A ‘hot’ fill from empty to 300 usually needs topping off once cooled to get it as near to 300 as possible though. Slow/cooled fills take longer but will drop much less.

Unusual that a diving shop hasn't filled to 300bar. They usually have a cold fill station.
Does your new stamp on the bottle say MDE?

Has anyone ever had a tank that actually failed a test? I've never heard it mentioned on the forum (or the old one) if so.
Just the date 11/24, maybe they think I don't have a stop best fittings kit so I can check the pressure, they owe me 40 bars of air, time to shoot that weird mascot that stands outside the shop.
I was gonna shoot it anyway, it's asking for it, gonna do it The Day of the Jackal style and practice on a melon first.

I had a bottle fail test on the valve threads, not the actual bottle.
New valve and all was well.
