Have you got fixed up yet, I see you are from Mansfield and there is someone in the area that sell's rent free gas, I will find the number out if you want it.
Found the number, Weldgas UK 08000778793, if I remember right you pay a one off for the bottle £50, then £30 for a refill, you get the £50 back if you return the bottle. They are based in Mansfield so local to you, hope this helps

I emailed Weldgas uk and had the reply below,decent prices but the price for the bottle deposit return seems a bit low to me,if i'm paying £50 deposit then that's the amount i want back when i return the bottle
Hi Alan
Price for 10 litre 200 bar Argon/Co2 (7% Co2, 2.5% O2 and 90% Ar)
£35 gas/refill
£50 deposit (£45 refundable for up to 2 years, £22.50 if kept above 2 years)
If you want to purchase a bottle outright they are £100
think this is the man i use gd chap always help me out when poss and i live the other side of derby so he not even local to me but well worth the trip? only fills upto 150bar but its been a few months since ive had a new bottle.
