Common questions about boiler repairs in High Cross
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.
Is it worth repairing an old boiler?▾
Honest answer: if it's over 12 years old and the repair is more than £400, replacement usually makes more financial sense. We'll lay out both options without pressure.
Do you charge a callout fee?▾
We charge a clear diagnostic fee (told to you upfront before we attend). It covers proper on-site diagnosis. The repair itself is then quoted as a fixed price you agree before any work starts.
