boiler repairs in High Roding: questions we get a lot
Why have I lost hot water but heating still works?▾
On a combi boiler this is the classic diverter valve symptom — the valve that switches the flame between heating and hot water has stuck. Common, and usually a one-visit fix.
How much will it cost?▾
Diverter valve replacement on most boilers is £180–£320 fitted. We'll give you a fixed price after diagnosis before any work starts.
Do you guarantee repairs?▾
Yes — 12 months on the workmanship and any parts we supply.
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.
