Fuse Box & Consumer Unit Upgrades

Modern, safe consumer units sized for today’s electrical load.

An undersized or ageing consumer unit is the root cause of most nuisance tripping. We replace old fuse boards with modern units, properly rated, RCD-protected and labelled, so your power stays on and your home stays safe.

What's included

  • Old fuse box replacement
  • RCD & RCBO protection added
  • Dedicated circuits for AC, ovens & EV chargers
  • Clear labelling & test certificate
  • Surge protection options

Available across the entire Algarve.

Signs your consumer unit needs attention

Frequent tripping, unlabelled circuits, no residual-current protection or a board that cannot support air conditioning, an oven or EV charging are reasons to arrange an assessment. A correctly designed board improves protection and makes faults easier to diagnose.

Common questions

Does a board that keeps tripping always need replacing?

No. Tripping can come from a single faulty appliance, a damp outdoor circuit or an overloaded circuit. Find the cause first; replace the board when it is old, undersized, lacks RCD protection or cannot take new circuits.

What is the difference between a breaker and an RCD?

A circuit breaker (disjuntor) protects one circuit against overload and short circuits. An RCD (diferencial) switches off when current leaks to earth, which is what protects people from electric shock. A modern board uses both.
