What’s included in your Wokingham boiler service
Thermotec provides a manufacturer-standard service — not just a basic check. Every service across Wokingham and RG40 includes a full 25-point inspection, and as a Vaillant Advance Partner and Viessmann accredited installer, the work meets the exact specification required to keep your extended warranty valid.
7 warning signs your boiler needs attention
- Unusual noises (kettling or banging) — limescale on the heat exchanger, common in Wokingham’s hard water area
- Yellow or orange flame — incomplete combustion, potential carbon monoxide risk. Call immediately
- Frequent pressure drops — failing expansion vessel or hidden leak introducing oxygen and causing internal rust
- Lukewarm water or cold radiators — sludge restricting flow, forcing the burner to overwork
- Visible leaks or moisture — a small drip today can short-circuit the PCB tomorrow
- Unexplained energy bill increases — dirty burner or scaled heat exchanger burning more gas for the same heat
- Unusual smells — rotten egg indicates gas; metallic smell indicates electrical overheating. Turn off immediately
Vaillant and Viessmann warranty servicing — accredited installer
As a Vaillant Advance Partner and Viessmann accredited installer, Thermotec provides manufacturer-standard servicing that keeps extended warranties valid. This is critical — Vaillant and Viessmann extended warranties (up to 12 and 15 years respectively) require annual servicing by an accredited installer. Servicing by a non-accredited engineer can invalidate the warranty.
Every Vaillant and Viessmann service is completed to manufacturer specification and a digital Benchmark service record is provided immediately after the visit.
Viessmann 5-year strip-down service: Viessmann requires a deeper strip-down service at the 5-year interval — removing internal components including the burner and heat exchanger for thorough cleaning. Fixed price £240. Stuart will confirm whether your Viessmann boiler is due this service when you book.
Moving home? Ask about our new home and seller’s inspections
If you’ve just moved into a Wokingham property, a standard service won’t catch everything a previous owner left behind. The 25-Point New Home Inspection goes further — a full boiler service plus a water quality lab test, radiator and valve audit, and a walkthrough of your heating controls, all in one 2-hour visit for £192.
Selling instead? A recent service record and Gas Safety Certificate (CP12) give buyers and solicitors the “enquiry stage” proof they typically ask for, helping you avoid last-minute renegotiations. Compare the new home and seller’s inspections →
Landlord boiler servicing and CP12 certificates
Landlords are legally required to have an annual gas safety check on all rental properties. Thermotec combines an annual boiler service with a CP12 Gas Safety Certificate in a single visit for £150 — saving the cost of a second call-out. The CP12 is issued immediately after the visit.
Stuart covers properties across Wokingham, Earley, Woodley, Finchampstead, Arborfield, Bracknell and all RG40 and RG41 postcodes. For landlords with multiple properties, call to discuss a schedule. CP12 certificate details →
