Oxygen can be supplied up to 230 bar providing the cylinders are in current test and oxygen clean. Either a suitable diving qualification or oxygen administration certificate will be needed to obtain these fills.

Oxygen currently costs 2.5p per litre plus an added £1.50 for a top-off.

A minimum price for Oxygen/EAN dispense is £4.

All Findivers Members + Affiliated dive club members receive the top off free of charge (See Links).

For higher % of Oxygen please see in-store for price.


Please bring your certification with you for your first fill. This will allow us to add you to our database for future reference. Nitrox and Oxygen can only be signed out if an appropriate certification is provided. We reserve the right to charge for any Nitrox or Oxygen which has to be drained due to customers not being able to provide suitable documentation. Failure to pay for Nitrox or Oxygen drained will mean cylinders will be retained until the matter is resolved.
