Immersion heater not heating in Bridgend

This is routine work carried out weekly across CF31–CF35, so the process is settled: check immersion heater not heating, record it, quote it, complete it, certify it. It is written into the report either way, so nothing is hidden.

For post-war semis in Brackla and Wildmill in particular, immersion heater not heating throws up a fairly predictable set of findings. Where the spur switch itself has failed we replace it — that's a common failure point often missed. Nothing is charged for on the basis of a guess. Where a reading is borderline, it is reported as borderline. Around Bridgend County Borough Council that is a familiar finding rather than an alarming one.

We are NICEIC-registered, Part P notifiable, and every visit ends with a written certificate. Where the answer is to leave it alone for now, that is exactly what we will tell you. It gets photographed if it will be hidden afterwards. You can spend a lot on immersion heater not heating or very little. Which one is right depends on measurements, not on the quote.

Safe checks you can do first

Check the switched fused spur is on and the neon (if fitted) is lit.
Check the timer/controller display for a reset flag after any recent power loss.
Feel the tank — cold top means element failure, cold bottom means thermostat fault.

Likely causes

The immersion thermostat has tripped its manual reset button after an overheat event.
The element itself has failed — very common after 8–10 years of use.
The switched fused spur feeding the immersion has a blown 13A fuse or failed switch.
The timer or off-peak controller has lost its schedule after a power cut.

When to stop and call

If the spur is on, the timer is scheduled correctly and the tank is stone cold after 2 hours.

How we fix it

We isolate at the spur, test the element for continuity and insulation, and replace element or thermostat as needed. Where the spur switch itself has failed we replace it — that's a common failure point often missed.

Typical price: £95–£160 for element or thermostat replacement.

Bridgend context

Timescales are given honestly. If a part has to come, we say when rather than leaving it open. In practice that means checking immersion heater not heating before anything is replaced.

FAQs — immersion heater not heating in Bridgend

How long does an immersion element last?+

8–12 years in soft-water areas, 5–8 years in hard-water areas where limescale accelerates failure.

Is it worth repairing or replacing the tank?+

If the tank is 20+ years old and lagged with a foam jacket rather than sprayed insulation, replacement is usually the right call.
