Thermotec Accreditations — Gas Safe Wokingham
Accreditations are not just logos on a website. Each one has specific practical consequences for Wokingham homeowners — from keeping manufacturer warranties valid, to being legally authorised to carry out work that other engineers cannot. This page explains what each accreditation means and why it matters.
Legal qualifications
■ Legal requirement
Gas Safe Register
Registration No. 599015
The law requires Gas Safe registration for any gas work in the UK — boilers, fires, cookers. Every Thermotec job is carried out under Reg. 599015. Always verify before allowing gas work in your home.

■ Legal requirement
G3 Qualified
Unvented hot water cylinders
G3 is the separate legal qualification for unvented cylinders (Megaflo, Gledhill, Worcester Greenstore). Gas Safe alone does not cover this. Stuart is G3 qualified — most local plumbers are not. Cylinder service →
Manufacturer accreditations
Why manufacturer accreditation matters for your warranty
Most manufacturer warranties (Vaillant, Viessmann, Worcester) require annual servicing by an accredited engineer. Having an unaccredited engineer service your boiler voids your warranty — even if they are Gas Safe registered.
■ Warranty critical

Water treatment — especially important in RG40
Why this matters specifically in Wokingham
Wokingham’s water runs at 330–380 mg/L hardness — among the top 5% hardest in England. Limescale and sludge protection is not optional here. It’s what separates a boiler that lasts 15 years from one that fails at 8.
