We've had Jem Gas on board for multiple jobs in the past and each time they've delivered on their promise to hand over a project we're satisfied with.</p><p>Jon himself has gone out of his way on several occasions to go above and beyond in order to get our projects done on time and within our budget.

We wanted to have our hot water cylinder ripped out and changed to an infinity gas califont . Jon was great to deal with and provided the best quote. He had solutions for every obstacle we had and completed the job in a timely manner and to a very high quality. Very happy with our products and service. Will definitely use Jon again. thanks mate

Jon was professional and did a great job swapping my old 1980s taps to gleaming new chrome ones. Even fitted them into the old bathroom sink/vanity. Thanks!
