Hot Water Cylinders

A vented cylinder works with a cold water tank in the loft and relies on gravity for water pressure. An unvented cylinder connects directly to the mains, giving you much better pressure throughout the house. Unvented systems are now the more popular choice for new installations, particularly in homes where good shower pressure matters.

A well-maintained hot water cylinder typically lasts between 15 and 25 years. If yours is getting noisy, struggling to keep water hot, or you are noticing a drop in pressure, it may be time to look at a replacement.

The cost depends on the cylinder size, the type (vented or unvented) and the complexity of the installation. Cylinder prices have risen sharply in recent years. As a rough guide, a replacement direct cylinder including labour now starts from around £1,400+, with larger or unvented systems costing more. We will always give you a fixed price before any work starts.

A straightforward cylinder swap usually takes a day. If additional pipework or controls need updating, it may take a little longer. We will let you know at the quoting stage.

Gas Safe Register is the official, government-approved list of engineers who are legally allowed to work on gas appliances and installations in the UK. It replaced CORGI in 2009. Our engineers are Gas Safe registered, which matters whenever a cylinder installation involves work on a gas boiler or its pipework.
