G3 Unvented Cylinder Installation in Sevenoaks
An unvented hot water cylinder offers several practical advantages over a traditional vented system in a Sevenoaks home: no cold water storage tank to maintain, mains-pressure hot water at every outlet, and a generally more efficient use of stored heat.
Our G3-registered engineers install unvented hot water cylinders across Sevenoaks, ensuring all necessary safety devices are fitted correctly and the system is commissioned to the manufacturer’s specification. We can advise on the right cylinder size for your household’s demand. We cover Sevenoaks and surrounding areas of Kent and Medway.

Old fuse box replaced with a new consumer unit in one day. NICEIC certified, all circuits labelled clearly, and the engineer was neat and professional throughout.
Really easy to book, turned up on time, and completed the service without any fuss. Received the service record the same day. Will book with them again next year.
Had the fuse box changed and the difference is noticeable. Far better RCD protection now and everything clearly labelled. Professional job from start to finish.
