Service checklist
What’s included in a Worcester Bosch service
Every Thermotec Worcester service follows the manufacturer’s multi-point inspection schedule — a comprehensive check of every safety-critical component, not just a visual look-over.
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 for leaks. Mandatory Gas Safe requirement at every service.
Burner & heat exchanger clean
Burner and heat exchanger cleaned to restore combustion efficiency — directly reduces gas consumption and prevents EA fault lockouts.
Flue & condensate check
Flue terminal and condensate pipe inspected. Blockages here cause the most common winter fault codes (EA, C6) in Wokingham homes.
Safety devices test
Pressure relief valve, expansion vessel and all safety interlocks tested. Prevents overpressure faults and protects the heat exchanger from cracking.
Radiators & controls check
Full heating system check — radiators, thermostat, programmer and controls tested to confirm the whole system is operating correctly.
System pressure & pump check
System pressure checked and topped up if required. Circulating pump verified — the most common cause of A1 pump faults on Worcester boilers.
Digital service record
Full digital Benchmark service certificate issued same day. This is the document Worcester Bosch requires to validate your manufacturer warranty.

Fixed prices — confirmed before we start

Common questions
Worcester Bosch servicing FAQ
Why is it important to service my Worcester Bosch boiler?
Regular servicing ensures your boiler runs efficiently, prevents costly mid-winter breakdowns and detects safety issues like gas leaks or carbon monoxide build-up early. For Worcester Bosch boilers, an annual service by a Gas Safe registered engineer is also a condition of keeping your manufacturer’s warranty valid.
How often should I have my Worcester boiler serviced?
At least once a year. Annual servicing maintains peak efficiency, reduces the risk of EA, A1 and C6 fault lockouts, and is the single most effective way to extend the lifespan of your boiler.
Do I need to service my boiler if it’s still under warranty?
Yes — most Worcester Bosch warranties explicitly require an annual service by a Gas Safe registered engineer to remain valid. Skipping a year can void your warranty claim. We provide the digital Benchmark record Worcester Bosch requires at every service.
What does a Worcester Bosch boiler service include?
A full multi-point inspection covering the burner, heat exchanger, seals, gas pressure, flue, condensate pipe, safety devices, system pressure and pump. We also check radiators and controls and issue a full digital service record. See the checklist above for the complete detail.
How long does a Worcester boiler service take?
As long as it takes to do every check properly — we don’t rush a service to hit a time slot. 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 Worcester 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.
Can I book my boiler service online?
Yes — pick your exact time 24/7 at thermo-tec.co.uk/schedule-an-appointment. No phone tag, no voicemails. Confirmation in seconds.
