The same installer Mark Gundill from Gregor installed my boiler at my previous property 8 years ago! Mark did another fantastic job with this install and was a pleasure to have on site.

We knew the work required would be challenging but the engineers discussed and listened so that we were all in agreement about how it should be carried out. (Where the pipes should go etc.). The installation was professionally done and we were well looked after with heaters supplied etc. Every person who came or answered the phone was purposeful and helpful. Well done for customer service.
