What the service covers
What does an unvented cylinder service include?
An unvented cylinder service checks the parts that control stored-water temperature and pressure. We follow the manufacturer's instructions, inspect the accessible cylinder and pipework, test the relevant safety devices and expansion arrangement, and complete the service record. It is proper maintenance, not a quick glance into the airing cupboard.
Safety valves and discharge
We check the relevant temperature, pressure and expansion relief valves, along with the tundish and visible discharge route, following the cylinder instructions.
Controls and service record
Where applicable, we check the controls, thermostat operation and visible wiring, then record the visit and explain any further work the cylinder needs.
For the wider industry guidance behind these checks, see the Hot Water Association servicing guide. The instructions for your own cylinder always take precedence.
Choose the right route
Is this the right service to book?
Use this diary when the unvented cylinder is the only appliance that needs its annual service. If another part of the heating system also needs attention, start with the matching option below so the diary allows enough time.
Cylinder only
Stay on this page and book directly into the live diary. Landlords can add tenant, access and property details during the booking.
Gas boiler and cylinder
Start with the gas boiler service diary and add the cylinder service for +£45 near the end. Both services are then booked together.
Heat pump and cylinder
Our heat-pump service already includes the hot-water cylinder. Heat-pump customers do not need to book this visit separately.

Unvented cylinder service FAQs
How often should an unvented cylinder be serviced?
The Hot Water Association recommends servicing an unvented cylinder every 12 months. The cylinder manufacturer's instructions take precedence, so keep the make and model available if you know them.
What is checked during an unvented cylinder service?
The engineer follows the cylinder manufacturer's instructions and checks the accessible cylinder, expansion arrangement, safety valves, tundish and discharge route, controls and visible wiring where applicable. The visit is recorded and any further work is explained.
Can I add the cylinder to a gas boiler service?
Yes. Start from the gas boiler servicing page and choose the cylinder add-on near the end. The diary will show the combined price before you confirm.
Does heat-pump servicing include the cylinder?
Yes. Vector Heat's heat-pump service already includes the hot-water cylinder, so heat-pump customers should book through the heat-pump servicing page.
What if the cylinder is leaking or water is passing through the tundish?
Tell Vector Heat before booking if the cylinder is leaking, discharging water or has another known fault. Annual servicing is planned maintenance, so the office may arrange a different appointment for diagnosis or repair.
