Immersion heater repair in Colchester
Lighting Electrical repairs immersion heaters on hot water cylinders for homeowners, landlords and businesses in Colchester and the surrounding Essex towns. We test the element, thermostat and supply, then repair or replace what has failed and leave the cylinder heating again.
“Ten years on Colchester housing stock and I have seen most of it: terraces where the lighting circuit has been extended once too often, boards fitted before RCDs were standard, new builds with sockets nowhere near the kitchen. I check the earthing, the bonding and whether the supply will carry another load before I price anything, because the age of a house settles nothing on its own.”

Immersion heater not heating water
- Cold taps on the hot side, with the immersion switched on, mean the element or thermostat in the cylinder is not heating the tank.
- The tank stays cold even with the immersion switch on, so showers and hot taps run cold.
- The fuse board trips when you switch the immersion on, which means a failed element, thermostat or damaged flex.
- A rented home with a cylinder still needs hot water, and a failed immersion is a repair rather than a heating replacement.
What is covered
The job is the electrical repair on the immersion and the parts that heat the cylinder.
Included
- Testing at the immersion switch, the isolator and the fuse board
- Insulation and continuity tests on the element and thermostat
- Replacement of a failed immersion element or thermostat
- Repair of damaged flex or connections on the immersion circuit
- The relevant electrical paperwork when the work is complete
Not included
- Repair of a gas boiler or a heating appliance that is not the immersion
- Supply and fit of a new hot water cylinder
- A full house rewire
What happens on the day
You get the power isolated, the element and thermostat tested, and the cylinder heating again before we leave.
- 01
Arrival and isolation
We find the cylinder and isolator, cut the power to the immersion, and keep the cupboard or plant space clear enough to work.
- 02
Testing the element and thermostat
We test the element, thermostat and flex, then replace the failed part or repair the wiring that caused the trip.
- 03
Power back on and paperwork
We restore the supply, check the cylinder is heating, and leave the relevant electrical paperwork for the work done.
Immersion heater repair prices
Immersion heater repair starts at £70/hr. That rate is the labour for testing the element, thermostat and cylinder wiring and for the repair work that follows.
- Hours on site rise when the cylinder has to be drained to replace the element.
- A new immersion element or thermostat is charged on top of the hourly labour.
- Tight access to an airing cupboard or plant room adds time at the same hourly rate.
What you get after immersion heater repair
You get hot water from the cylinder, an immersion circuit that stays on, and written paperwork for the repair.
- Hot water from the cylinder
- The immersion heats the tank so showers and hot taps run hot from the cylinder again.
- An immersion circuit that stays on
- The fuse board no longer trips on that circuit because the failed element or damaged flex has been replaced.
- A tidy cupboard and written paperwork
- Covers go back on, old parts leave with us, and you keep the written price plus the electrical paperwork.

Immersion heater repair questions
A failed immersion leaves a cold cylinder, a trip at the fuse board, or both, and the repair starts with a test.
How much does immersion heater repair cost?+
Immersion heater repair starts at £70/hr. The hours on site follow whether the element, thermostat or wiring has failed, and whether the cylinder must be drained. A new element or thermostat is extra to the labour.
— Valandi Kotorri
Why does the immersion trip the fuse board?+
The immersion circuit trips when the element or flex is passing current to the tank or pipework. We isolate that circuit, test the element and replace the failed part. The fuse board stays on once that leak is gone.
— Valandi Kotorri
Do you drain the hot water cylinder?+
The cylinder is drained when the immersion element is being replaced. A thermostat only repair leaves the water in the tank. We test first so you know which of those two jobs it is before any water is run off.
Do landlords get immersion heater repair from Lighting Electrical?+
Yes, Lighting Electrical repairs immersion heaters for landlords in Colchester and the surrounding Essex towns. A failed immersion in a rented cylinder is a repair to restore hot water. The relevant electrical paperwork is left when the work is complete.
Do you replace the immersion element or repair it?+
We replace the element or thermostat when that part has failed, and we repair the wiring when the parts are sound. Labour starts at £70/hr and parts are extra. You get a cylinder that heats on the immersion again.
