Electrical Installation and Rewiring in Odemira and the Costa Vicentina

What a Complete Installation Actually Involves

A new installation is not "running cables". It is deciding how many independent circuits the house will have and what sits on each. An ordinary house needs, as a minimum, separate circuits for lighting, general sockets, kitchen, appliances, heating and outdoors — plus a dedicated one for an induction hob, air conditioning, a borehole pump or car charging.

The benefit shows up in daily life: when something fails, only that part of the house loses power. In an isolated house, that is the difference between an inconvenience and losing the water pump on a Sunday.

The second decision is cable size, and it cannot be corrected later without opening walls. In a house with long runs — annexes, a detached garage, a borehole at the end of the plot — size is not chosen by load alone. It is chosen by distance.

Schist, Rammed Earth and Old Masonry

Three things come up regularly when renovating in this municipality. The first is an installation with no earth conductor, common in houses predating the 1980s, which makes the residual current device incapable of protecting as it should.

The second is the difficulty of cutting chases. In schist or rammed-earth walls, opening up to run conduit is slower, more expensive and sometimes inadvisable from a structural point of view. The answer there is usually well-integrated trunking or routes through ceilings and skirtings — and that is a decision to take with whoever is doing the building work, not after it.

The third is the earth. In dry, rocky ground a single electrode can give a useless reading, particularly in summer. We always measure, and when needed it is resolved with additional electrodes or a different location — never by assuming it is fine because there is a green-and-yellow wire.

Doing It All in One Go: What People Regret Later

If the walls are going to be open anyway, that is the only moment when running data cabling costs almost nothing. In a house that will become a holiday let, or where somebody will work remotely, it is the decision most often regretted for not having been taken.

The same goes for spare conduit: from the consumer unit to the garage for a future charger, from the unit to the roof for future solar, from the gate to the house for a video entry system. An empty conduit costs pennies during the work and prevents an entire job two years later.

If you are renovating, it is worth deciding all of it at once rather than in three separate quotes. That is also when it is cheapest to get the consumer unit right, because the power is already off and the labour is already on site.

Can the installation be done in phases?

It can, and it is common. What cannot be split is first fix: chases and conduit are done in one go, because opening walls twice costs more than it saves. Second fix — accessories, lighting, automation — can wait for a later phase without any penalty.

The house is built of schist. Does that complicate things?

It complicates the cable route, not the installation itself. Cutting chases in schist is slow and sometimes inadvisable, and in those cases we use well-integrated trunking or routes through ceilings and skirtings. It is a decision to take with whoever is doing the building work, before plastering.

When should I call the electrician during a renovation?

Before plastering and before floors go down. That is the only moment when running cable and conduit is cheap. Calling after the building work is closed up is the number one reason quotes double.

How many sockets should I allow per room?

More than seems necessary today. A living room with a television, router, console and chargers runs short on two sockets, and adding one later means new cable, not just an accessory. Allowing extra costs little in a new installation; allowing too few is paid for in building work.

Do you work with architects and builders?

We do, and it is what works best. Electrical decisions have to be taken before first fix, and when there is coordination with whoever is doing the building work you avoid the changes that appear after plastering — which are what make quotes grow.

Do I have to move out during the work?

For a partial renovation normally not: we work by zones and keep power in the rest of the house. For a full installation there are days without general power, which we agree in advance. If there is equipment that cannot be switched off, tell us at the visit.

Does the new installation come certified?

It does. A new installation or a significant renovation requires a technical file and certification in order to be connected on a new contract. We do the interior installation and handle the documentation it requires.

How much does a full electrical installation cost?

It depends on the number of rooms, light points and sockets, and whether it is new-build or a rewire. For a typical 2-3 bedroom house around Odemira, a complete installation usually runs 2,500 to 5,000 euros including materials. We give a fixed quote after seeing the plans and the property.

Do you work on holiday homes and short-term rentals?

Yes, and it is worth designing the installation with that in mind: separate circuits, protection that copes with heavy summer use, and enough sockets for guests. A fault in August with the house full costs far more than getting it right from the start.
