Electrical rewiring in Portugal
Electrical rewiring in Portugal runs from €5,000 and typically takes 2 to 4 weeks. Older buildings often need a panel upgrade first, many still run a 6.9 kVA supply that cannot handle a modern induction hob, oven, and dishwasher running together. remodel matches you with a vetted and verified contractor working to RTIEBT standard, and checks the itemised quote against regional project data before you see it.
