boiler servicing in Ongar: questions we get a lot
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 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.
Do you do landlord CP12 certificates?▾
Yes — combined service + CP12 packages available, with bulk pricing for landlords with multiple properties.
