I phoned boc as they are local to me, in actual fact I have lots of choice of places to get gas but they only provide thier own bottles and as already noted here, my bottle is mixed gas and I need c02, boc charge £20 to fill and £2.50 rental a month and that's delivered, however the rep was quite interested in where I got the bottle as it remains their property and should not have been sold to me, I can get this bottle filled elsewhere but I can't use this mix, anyone in surrey interested in making an offer for it ? It has gas in it though I am not sure how much.
