Efficient installation by a responsive, reliable company
We have used GK for many years to service our 35+ year old boiler so went to them straightaway when we decided to get a new one. GK installed a new combi boiler and removed hot and cold water tanks over 3 days. The work was carried out very efficiently and the guys always cleaned up before they left. Soon after installation, we reported a small hiccup (boiler firing when cold taps were run) which was quickly dealt with via the boiler’s keypad. We are very happy with the combi boiler so far.Verified reviewerJob location: HP910 Plumber

The plumber arrived as stated in their email to replace an old toilet. His work was carried out professionally. He also replaced tiles that needed to be removed and cleaned up after completion.
