10 Replacement boiler and cylinder
Posted 19 December 2025
Job location: DE21Super experience from survey to completion. Sam understood what we needed in our new home and made recommendations of where to relocate the boiler. Kim was in regular contact throughout the process. Our engineer Alex was brilliant, highly skilled but made a point of explaining what he was doing and why. I was out at work when Alex had finished the work but I really appreciated him handing everything over to me via 10-15 minute video call to explain where everything was and how to operate our new system. KAS come highly recommended by us, will 100% use again! - RRobert F

10 Combi boiler fitting
Posted 25 June 2025
I can confirm that they have excellent Knowledge, Attitude & Skills (KAS). I am very happy and relieved to have a Combi boiler installed perfectly with good finish, replacing an old heater boiler and placing it where the old cylinder was, removing tanks no longer needed, bricking up nicely and replacing a pump shower to a new one compatible with the Combi.Verified reviewerJob location: DE73 - KKaty W
