Before finishes, plan the circuits
A renovation is the right time to think through appliance locations, lighting, workspaces and future needs. A beautiful new kitchen can still be inconvenient if sockets and circuits were considered too late. Put the room layout and intended equipment into the brief before plastering or cabinetry is agreed. Ask for an assessment of what can remain and what needs replacing rather than assuming every older installation needs a complete rewire.
Full rewire or targeted improvement?
The answer depends on the condition, capacity and arrangement of the existing installation. Board replacement, new circuits and whole-property rewiring are different scopes. A competent professional should explain the findings behind the recommendation, identify any limitations and outline the disruption. A newer distribution board on its own does not prove that all the wiring elsewhere is suitable.
Occupied homes and shared buildings
Discuss planned power interruptions, access to rooms, furniture protection and whether the home can remain occupied. In a Lisbon apartment, cable routes may pass near shared spaces or affect building fabric. Establish responsibilities with the condominium or landlord before work begins. Do not treat an electrical quote as permission for structural changes.
A quote that is easy to compare
Ask for a circuit schedule, accessory quantities, the finish or product range, testing and documentation, exclusions and making-good responsibilities. Include any planned AC, induction cooking, electric water heating or EV charging so those loads can be assessed together. Keep design, approval and installation decisions with appropriately qualified professionals.
Common questions
Does an older home automatically need rewiring?+
No. Age is context, not a diagnosis. Condition and testing help determine the appropriate scope.
Should I replace the board first?+
Ask for an assessment of the installation as a whole. A board upgrade and the condition of existing circuits should be considered together.
