We supply and install unvented cylinders from leading brands, tailored to your property size, water demand and boiler system. Whether it’s a new build or a conversion from a vented system, we’ll ensure powerful, balanced water pressure and safe operation throughout your home.

Struggling with low pressure, temperature issues, or dripping overflow pipes? We’ll quickly diagnose and repair common unvented system faults, from failed valves and immersion heaters to expansion problems or scale build-up.

Unvented systems are pressurised and require annual safety checks. We inspect expansion vessels, pressure relief valves and temperature sensors to ensure everything is compliant, safe and operating at optimal levels.

To maintain performance and safety, unvented systems must be serviced annually by a G3-qualified engineer. Our detailed service includes testing all key components, checking for leaks and ensuring full compliance with Building Regulations.

If your existing hot water cylinder is outdated, undersized or unreliable, we can upgrade it to a modern unvented model. We’ll also improve insulation, pipework, and controls to maximise efficiency and minimise heat loss.

We install smart-compatible controls and cylinder thermostats to give you better control over water temperature and scheduling. Save energy and enjoy instant hot water exactly when you need it.
