How much does electrical rewiring cost in Portugal?

From €5,000 for a full rewire of a standard apartment, covering panel upgrade, new circuits, and a lighting plan. Older buildings with a 6.9 kVA supply often need a panel upgrade first.

How long does electrical rewiring take?

2 to 4 weeks for a full rewire of a standard apartment, though walls need to be opened and re-closed, so it is disruptive if the property is occupied during the work.

Do I need a permit to rewire a property in Portugal?

A full rewire that changes the circuit layout typically requires a Comunicação Prévia to the câmara municipal. Like-for-like replacement on the existing layout usually does not.

Are remodel.pt electrical contractors verified?

Yes. Every contractor holds a construction licence (alvará) checked against the IMPIC registry, works to RTIEBT wiring regulations, and is confirmed for working English before joining the network.

What's included

Panel upgrade

Consumer unit replaced and sized to the property, essential in older buildings still running a 6.9 kVA supply that cannot handle modern appliance loads.

Full circuit rewiring

Wiring replaced to RTIEBT standard across the property, with circuits separated correctly for kitchen, bathroom, and general use.

Lighting plan

Fixture points, switches, and dimming planned to the room, not just replaced one-for-one on the existing layout.
