JR Gas and Water were fast, efficient and very reliable. They sent a quote quickly that was itemised and comprehensive. I was able to approve the quote online and they were out the next day to fit the new hot water system. As the family have a very ill family member we were all very grateful. We had tried another service just before this company and they were all over the show with lots of comments about "extras", after providing an initial quote. So glad we changed to JR Gas and Water!
