Why pick Vaillant over Worcester?▾
Vaillant tends to edge ahead on hot-water performance and very-quiet operation. Worcester edges ahead on warranty length and parts availability outside London. We'll be honest about which fits your situation.
Do you stock Vaillant parts?▾
Common parts (PRVs, expansion vessels, F22 sensors) yes — on the van. Less common parts come next-day from Vaillant directly.
How long does a service take?▾
Usually 45–60 minutes for a domestic boiler in normal condition.
How often should a boiler be serviced?▾
Once a year. It's almost always required to keep the manufacturer's warranty valid, and it catches small issues before they become breakdowns.
What you get when you book us
- Calibrated combustion analyser used on every service
- Manufacturer-spec procedure followed
- Written service report supplied
- CP12 landlord certificates available
- Warranty paperwork preserved
