Consumer unit replacement and repair in Mallorca
An old consumer unit is not just ugly: it is where the risks concentrate. We explain when it can be repaired, when it must be replaced and what the new one should include.
Price depends on circuits, wiring and protection · Quoted after inspection
Repair or replace: the technical criteria
A unit can be repaired when the problem is specific: a worn device, a loose terminal, a failed protective device. It should be replaced when the whole no longer does its job: no RCD, circuits not separated, wiring that cannot carry the load, or no room to protect what is there.
The most common mistake is replacing only the RCD or increasing the breaker rating so that “it stops tripping”. That does not fix the problem: it hides it and shifts the risk to the cable.
A new unit is designed around circuits and actual consumption. It is not about adding more protection, but the right protection.
Repair or renew
Two common scenarios, two different answers.
| Situation | Recommendation | Why |
|---|---|---|
| Unit with fuses or no RCD | Replace | It does not protect people against earth leakage |
| One specific breaker fails | Repair | It is a single replaceable device |
| Frequent unexplained tripping | Diagnose first | It may be an earth fault, not the unit |
| Kitchen or bathroom refurbishment | Add circuits | New load needs its own line |
| Unit with no space and no labels | Replace | You cannot protect what is not identified |
| Burning smell or scorch marks | Replace urgently | There is an active hot spot |
How a unit is replaced
Inspection and measurement
We check which circuits exist, what each one draws and the cable cross-section.
Written quote
Number of circuits, protection, materials and labour. No surprises.
Installation
Scheduled shutdown, new unit fitted and circuits transferred in order.
Testing and labelling
Every circuit tested and labelled, with a job sheet and photos.
What must never be done
Fitting a higher-rated RCD so that it stops tripping. The RCD protects people by sensitivity, not by rating. If it trips, there is earth leakage.
Replacing the unit without inspecting the installation. A new unit connected to deteriorated wiring is still a risk — just a tidier one.
Leaving circuits unidentified. If one day the kitchen must be isolated, you need to know which switch it is. Labelling is part of the job, not an extra.
About price: a flat consumer unit and a commercial unit with an industrial kitchen have nothing in common. Publishing a single figure would be selling smoke. We quote after seeing the number of circuits and the state of the wiring.

Tell us the job and we will call you
We do not handle dangerous emergencies through a form: if there is smoke, sparks, a burning smell or a hot consumer unit, switch off the supply if you can do so safely and call.
Response time: the phone is answered 24 h. Attendance is assigned by area and by the technician available at that moment; we give you a specific window when you call.
Request a consumer unit quote
Tell us whether it is a house or premises, roughly how many circuits there are and whether the current unit has an RCD. We will call you to agree the details.
What clients ask before hiring us
How much does it cost to replace a consumer unit?
It depends on the number of circuits, the state of the wiring and the protection required. It is quoted in writing after the inspection, never blind over the phone.
Do all the cables have to be replaced?
Not always. If the cross-section and condition are correct, they are reused. If they are deteriorated or cannot carry the load, the affected run is replaced.
Can the unit be replaced without cutting the power?
The replacement requires a scheduled shutdown. We give notice and keep it as short as possible.
What is a time-delayed RCD?
An RCD with greater resistance to nuisance tripping, useful where there are surges or sensitive electronics. It does not replace fixing a real earth fault.
Does the new unit include the certificate?
The CIE is a separate document. We handle it together with the unit when you need it: inspection, corrections and submission to the distributor.
How long does it take?
A domestic unit is usually done in a day if the wiring holds no surprises. Commercial premises or complex installations take longer and are planned.
Is your consumer unit over 25 years old?
It does not always need replacing, but it always deserves an inspection. Tell us what you have and we will tell you what is needed.
