Your hot-water system
The cylinder services I can help with
Unvented hot-water cylinders are pressurised systems. Every installation is different, so I’ll discuss your needs and arrange a visit where needed before recommending work.
Servicing & Maintenance
Maintenance appropriate to the manufacturer’s instructions, with attention to expansion arrangements, safety controls and discharge provisions.
Fault Finding & Repairs
Assessment of poor hot-water performance, unusual discharge, pressure problems and related cylinder components before deciding on repairs.
Associated Plumbing Work
Changes to connected hot- and cold-water pipework, valves and other suitable plumbing-side components as part of a cylinder project.
G3-qualified work
Safety and good workmanship matter.
Unvented systems need correctly functioning temperature and pressure protection, expansion arrangements and discharge pipework. Manufacturer instructions and applicable Building Regulations requirements are important on installations and replacements.
I hold the G3 unvented hot-water qualification and will explain the proposed plumbing work and the next steps before it begins.

Common questions
Unvented cylinder questions
How often does an unvented cylinder need servicing?
Follow the manufacturer’s service and warranty guidance. Many manufacturers recommend regular, often annual, checks. The work required depends on the model and installation.
Why is water dripping or running through the tundish?
Water discharging through the tundish can have several causes, including an expansion vessel that has lost its charge or needs replacing, or a pressure relief valve that is passing. I can inspect the installation, check the relevant components and carry out the appropriate repair — whether that means recharging or replacing the expansion vessel, replacing a faulty valve, or addressing another fault. The discharge pipe must remain unobstructed until the issue is resolved.
Can you replace an existing cylinder?
Yes, where suitable. I’ll review the installation, your hot-water needs and the requirements for a replacement before discussing the options.
Which areas do you cover?
I’m based in Potton, with local work around Sandy, Biggleswade, Gamlingay, St Neots and surrounding Bedfordshire and Cambridgeshire villages.
