Before you decide
From swapping a single socket to wiring a whole home or business. This is what we get asked for most in Mallorca, all to the REBT and with the paperwork in order.
New installation or a full rewire: main board, circuits, earthing and switches and sockets. We size it to what you actually use, so you've got power where you need it and everything's safe.
Fitting and renewing boards with circuit breakers, RCDs and surge protection, to your home's layout. We use Schneider Electric, Hager and Legrand gear — that's what we put in every day.
We issue the Electrical Installation Certificate (the boletín) and register it with the electronic office of the Govern de les Illes Balears. It's what you'll be asked for to connect the supply, increase the power or change the holder.
Finding and fixing faults, adding light points, fitting low-consumption LED lighting and electrical renovations. And we leave you ready for solar self-consumption and EV charging.

Electrical Installation Certificate registered with the Govern for connections, power increases and changes of holder.

When it makes sense
An old or undersized installation gives you grief: tripping RCDs, dated boards without enough protection, not enough power and, above all, risk. If your home's got a few years on it or you've just renovated, it's worth checking and bringing up to date.
You'll also need an authorised electrician when you're going to connect the supply, increase the power or change the holder: that's when the utility asks for the certificate, which only an authorised company can sign and which we register with the Govern de les Illes Balears.
We leave the lot done and certified to the REBT, with its documentation, warranty and invoice. Whether it's a fault, a renovation or a wiring job from scratch, we look at it and give you the safest answer for your case.
Common questions
Yes. As an authorised low-voltage installation company we issue the Electrical Installation Certificate (the boletín) and register it with the electronic office of the Govern de les Illes Balears.

Usually when contracting or increasing power, for a change of supply holder, after a renovation that alters the installation, or when the utility or the old certificate requires it due to age. We tell you exactly what your case needs before starting.
