Fault tracing
Diagnosing boiler, immersion or valve faults.
Losing hot water from your taps or shower is one of the most disruptive heating faults. Tell us what's happening and where you're located, and we'll help you request a local heating professional to diagnose the cause and help.

Share a few details and we'll help direct your request to a participating local professional. Submitting an enquiry is free and carries no obligation.
Not every no hot water problem looks the same. These are the signs that suggest it's worth requesting professional help.
No hot water at taps or shower.
A boiler lockout stopping hot water production.
A failed immersion heater on a cylinder.
A combi diverter valve not switching to hot water.
An immersion tripping the electrics.

A symptom is rarely the whole story. Whether it's a visible fault or a problem hidden behind a wall, under a floor or inside a fitting, understanding the likely cause first helps ensure the right no hot water work is carried out — and reduces the chance of it coming back.
The right approach depends on the problem. A professional can advise what's appropriate for your situation — not every professional offers every method below.
