Hot water not working is a priority — call 0141-374-0987 for fast same-day service.
We fix diverter valves, heat exchangers and hot water sensors on all combi boiler brands.
If we can't diagnose why your hot water is not working, you don't pay for the call-out.
Hot water not working is one of the most common combi boiler faults. The cause is often a failing diverter valve, a scaled plate heat exchanger, a hot water thermistor or a boiler fault code — not always a broken boiler. Our Gas Safe engineers carry parts for Vaillant, Worcester Bosch, Ideal, Vokera and Alpha, and we'll also check your heating pump and boiler fan so your whole system runs cleanly and you don't end up with heating not working too.

Engineer identifies the cause and confirms the repair cost before work starts.
Most hot water faults are fixed in a single visit with a 12-month warranty.
On a combi boiler this usually means a failing diverter valve, a blocked plate heat exchanger or a hot water sensor fault — not a broken boiler itself. We carry parts to fix it the same day.
Yes. A fault code on a Vaillant, Worcester Bosch, Ideal, Vokera or Alpha boiler can lock out hot water. We'll decode and clear the boiler fault code and repair the cause.
If the combi boiler is older and parts are obsolete, a boiler replacement with a new Vaillant, Worcester Bosch, Ideal, Vokera or Alpha may be cheaper long term. We'll advise honestly first.
