Think I'll check them out myself, see if they can do a better rental deal than BOC, I pay year in year out and have hardly used any gas in months and months - can't even remember when I last got a re-fill but I know if I go 'off-rental' I'll need to weld or cut something.
I have just spoken with a guy at BOC and I have secured a 2yr deal, cos I only need it over the next couple of years, the rental of a 'Y' size bottle, 5 cubic mtrs, for £60. That is £35 rental, £25 fill. Additional rental next year will be £35. Sorted.
I did phone New Gases - wanted 83.77 / yr rental, 87.00 fill and 14.99 del for a 7.5 cubic mte bottle. I have got a slightly smaller bottle with approx 8rs of weld time for considerably less. I feel quite happy
