Boiler and Heating Services - heating water cylinder

Unvented Cylinder Service

It is highly recommended that you have an annual cylinder service to ensure safety and to prevent nasty repair bills, as the price for a new boiler usually runs into the thousands.

If you still have a boiler warranty, for instance on a Gledhill Cylinder that usually comes with a 25 year warranty, then make sure you check the small print as it may be a requirement to have an annual service to validate the warranty. The Red Van Plumbers have serviced thousands of cylinders and boilers for homeowners, landlords and commercial properties in local areas such as West London, High Wycombe, Maidenhead, Windsor and Wooburn.

We recommended you get both your boiler and cylinder serviced at the same time by one of our professional engineers, and you will save £30 off the total amount by combining the 2 services. See our standard pricing page for further details.

What to Expect from your Cylinder Service

There are many different types of cylinder services so it’s always worth checking what you’re getting. Heppelthwaite the Red Van Plumbers offer a comprehensive service that takes approx 1 hour when servicing the boiler as well.

A cylinder service is a visual inspection and does not require the stripping down or dismantling of the cylinder.

Cylinder Servicing FAQs

We offer a complete range of plumbing, heating and renewable energy services across Buckinghamshire, Berkshire, West London, Oxfordshire and surrounding counties. Here are some frequently asked questions about our boiler installation services.

How often should a hot water cylinder be serviced?

Most hot water cylinders should be serviced once a year to help maintain safe operation and reliable performance. Annual servicing is especially important for unvented cylinders, where safety devices and controls need to be checked properly.

What does a cylinder service include?

A cylinder service typically includes inspection of key components, testing of safety controls, checks for leaks or corrosion, and confirmation that the system is operating correctly. The exact service depends on the cylinder type and manufacturer guidance.

Do unvented cylinders need servicing?

Yes. Unvented hot water cylinders should be serviced regularly to ensure safety valves, expansion controls and other key components are working correctly. Regular servicing also helps identify wear before it develops into a larger problem.

How long does a cylinder service take?

A standard cylinder service usually takes around one to two hours, depending on the type, age and condition of the system.

What are the signs that a hot water cylinder needs attention?

Common signs include inconsistent hot water, unusual noises, visible leaks, reduced water pressure or signs of corrosion around the cylinder or associated pipework. If you notice any of these, it is sensible to arrange an inspection.

Can you service cylinders as part of a wider heating system visit?

Yes. A cylinder service can often be arranged alongside other heating or boiler maintenance work, depending on your system and requirements.
