Warmth or overheating?
Some electrical devices may feel slightly warm in normal use, but a hot enclosure, a localised hot spot, a burning odour, discolouration or crackling is not something to ignore. Heat can build around a loose termination, an overloaded circuit or a failing breaker. It may remain concentrated inside the enclosure, so a normal-looking outer cover does not rule out trouble. Do not touch repeatedly to test the temperature, and never remove the cover to inspect the wiring.
Why heat develops in a consumer unit
Electrical current passing through a poor connection can meet extra resistance and produce heat. A breaker that is worn or damaged may also heat up, while an overloaded circuit can put sustained demand on its components. The cause may be related to one circuit or to a shared connection, and several parts can be affected if the problem has continued. The electrician needs to locate the heat source and understand its cause, not just replace the component that feels warm.
What to do while arranging help
If there is a burning smell, smoke, sparking, visible melting or a unit that is too hot to approach, keep clear and arrange urgent help. Switch off the supply only if the main switch is safely accessible and operating it does not bring you close to danger. Do not pile belongings around the enclosure or use it as a shelf. If there is smoke or fire, leave the building and call emergency services.
Inspection and targeted repair
The electrician checks the unit for heat marks, discolouration, loose or damaged terminations and signs of excessive load. They isolate before inspecting internal parts and use appropriate tests on the affected circuits. Depending on the findings, the work may involve correcting a connection, replacing a failed breaker, addressing circuit demand or replacing a unit that has sustained wider damage. The proposed scope and price are explained before work begins.
Checks before normal use resumes
After the cause has been corrected, the electrician checks the affected connections and circuits and tests the protective devices as appropriate. If a particular circuit remains off, there should be a clear reason and a plan for the next step. Do not restore power to a circuit against advice, even if the enclosure has cooled. A unit that has overheated once should be assessed before you rely on it for everyday use again.
What the visit involves
We will ask where the heat is noticeable and whether you have seen discolouration, heard crackling or noticed a smell. The electrician inspects the unit safely, isolates it as needed and traces heat-related damage to the relevant device, connection or circuit. The repair is agreed before chargeable work begins, and the affected circuits are checked after completion.
Aftercare and safety
Do not touch a hot consumer unit or remove its cover. If there is a burning smell, smoke, sparks or visible damage, keep clear and switch off only if the main control is safe to reach. Any smoke or fire means leaving the property and calling emergency services.
Book your electrical visit
Book an inspection if the consumer unit is unusually hot. If heat comes with a burning smell, smoke or sparks, keep clear and seek urgent help.
Further details for your electrician
A local hot spot can be more informative than general warmth, but do not touch the enclosure to compare temperatures. Tell the electrician which area seemed hottest and whether the heat followed heavy appliance use. If the unit cooled after power was switched off, report that too; cooling does not prove the connection or device is undamaged. These observations help focus inspection while keeping you away from the consumer unit.
How the price works
We charge a booking fee to hold your slot, then an hourly rate for the work itself. The fee changes with how soon you need us; the hourly rate changes with the slot you choose. You approve the price before we start, so there is no surprise on the invoice.

We diagnose on site
The engineer confirms the cause and tells you what the job involves and how long it should take.
You approve, we work
Nothing goes ahead until you agree the price. Labour is then charged per hour at your slot rate.
A consumer unit should not feel unusually hot, and a warm casing can point to a connection or component under stress. We check where the heat is coming from, assess any damage and advise on a safe repair before the fault worsens.
What our customers say about our electrical service
4.6 out of 5 from 11 reviews
Does what it says on the tin
No complaints about the work itself — clear explanation, sensible advice, fair price. Booking online was easy enough once I found the right job page.
Job: Smoke Alarm Replacement
Fixed it, but took longer than expected
Work itself was fine and tidy. Communication beforehand was patchy — I did not get the confirmation message and had to ring to check the slot. Would still use again.
Job: Flickering Outdoor Lights
Turned up when they said
Third time we have used Maintenance Men, and the same experience each time: agreed price, proper explanation, job done in one visit. The hourly rate is fair for the standard of work.

Questions people ask about overheating consumer unit
Straight answers to the things customers ask most often before booking.
Should I turn off a consumer unit that feels hot?
If it is unusually hot or accompanied by a burning smell, sparks or damage, keep clear. Switch off only if the main switch is safely reachable; otherwise arrange urgent help without approaching it.
How will the electrician diagnose the problem?
Possible causes include a loose connection, overloaded circuit or failing protective device. Inspection and testing are needed to identify the source and check for damage nearby.
Can the electrician just replace the hot breaker?
Only if checks show the breaker is the cause and the wiring and connections are safe. Replacing a device without finding why it heated could leave the fault in place.
Is slight warmth always a fault?
Not every warm electrical component is overheating, but a hot casing, hot spot, odour, crackling or colour change needs assessment. Do not open the unit to investigate.
How is the work priced?
You pay a booking fee when you book, and labour is charged hourly at a rate that depends on how quickly you need us. The full cost of the work is quoted before we start, so you approve it before any tools come out.
