I live and work in the Highlands of Scotland and we have used cylinders2go three times in last 12 months. What can I say - faster than getting a tank from the local plumbers merchant (unless they have the specific item in stock). The quality is very good and it arrives as a complete kit for unvented tanks. Delivery is very fast indeed, no extra charges and no fuss - if you need it to go a site and provide correct details then no problems have been encountered so far. They will phone you direct to make sure. And I mean delivery is fast - average has been 2 working days which up here from the "Mainland UK" is little short of amazing. I think they should concentrate their sales up here personally....... Price is "very competitive". So far I am happy to give an unreserved 5 stars to this company. If every company I dealt with was this good I would be a happy chap. If you have problems believing this then feel free to contact me.
