Frequently asked questions — boiler repairs, Codicote
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.
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.
How fast can you come out?▾
We aim for same-day on no-heat and no-hot-water situations. Tell us when you call if anyone elderly or with young children is in the property — we prioritise.
