Service checklist
What’s included in a Vaillant boiler service
Every Thermotec Vaillant service follows the manufacturer’s specific multi-point inspection schedule — not a generic boiler check. As an Advance Partner we are trained in Vaillant’s own service protocols for the full ecoTEC and ecoFIT range.
Full boiler inspection
All internal and external components checked — burner, heat exchanger, seals and pipework inspected for wear, leaks and corrosion.
Gas pressure & tightness test
Gas supply pressure and all connections tested. Mandatory Gas Safe requirement at every service — detects leaks before they become dangerous.
Burner & heat exchanger clean
Burner and heat exchanger cleaned to restore efficiency. Directly reduces gas consumption and prevents F.28 ignition and overheating lockouts.
Pressure sensor & pump check
Pressure sensor inspected for sludge blockage and pump verified — the components most likely to cause F.75 faults in Wokingham’s hard water area.
Flue & condensate check
Flue terminal and condensate pipe inspected. Blockages here cause the most common winter fault codes (F.28) across Wokingham homes.
Safety devices test
Pressure relief valve, expansion vessel and all safety interlocks tested — prevents F.22 pressure faults and protects the heat exchanger.
Radiators & controls check
Full heating system check — radiators, thermostat, programmer and controls confirmed operating correctly throughout the system.
Digital service record
Full digital Benchmark certificate issued same day — the document Vaillant requires to validate your manufacturer warranty.
Transparent pricing
Fixed prices — confirmed before we start
No hidden call-out charges, no surprise extras. Price agreed upfront every time.

Common questions
Vaillant servicing FAQ
Why is it important to service my Vaillant boiler?
Regular servicing ensures your boiler runs efficiently, prevents costly winter breakdowns and detects safety issues early — including gas leaks and carbon monoxide build-up. For Vaillant boilers specifically, an annual service is a condition of keeping your manufacturer warranty valid. It also dramatically reduces the risk of F.22, F.75 and F.28 fault lockouts.
How often should I have my Vaillant boiler serviced?
At least once a year. Annual servicing maintains peak efficiency, keeps your Vaillant warranty valid and is the most effective way to prevent fault lockouts before the winter heating season begins.
Do I need to service my boiler if it’s still under warranty?
Yes — most Vaillant warranties explicitly require an annual service by a Gas Safe registered engineer to remain valid. Skipping a year can void your warranty claim entirely. As an Advance Partner, we issue the digital Benchmark record Vaillant requires as evidence at every service.
What does a Vaillant boiler service include?
A full multi-point inspection covering the burner, heat exchanger, seals, gas pressure, flue, condensate pipe, safety devices, pressure sensor, pump, radiators and controls. We follow Vaillant’s own manufacturer service schedule as an Advance Partner — not a generic boiler checklist. A digital Benchmark record is issued same day. See the full checklist above.
How long does a Vaillant boiler service take?
60 to 90 minutes for a thorough service. You can book your exact arrival time online 24/7 at thermo-tec.co.uk/schedule-an-appointment — no waiting in for a vague window.
How much does a Vaillant boiler service cost in Wokingham?
From £96 for a full annual service, fixed price confirmed before we start. Landlords can combine the service with a CP12 Gas Safety Certificate for £150. No hidden costs, no call-out charges.
Can I book my Vaillant service online?
