Find Smoke Detector Installation Professionals in Algeciras – La Línea, Spain

Our company wants battery storage, Wallboxx and solar systems to be installed at our customers' premises. The devices are already present and must be electrically connected and commissioned. The connection is to be carried out professionally, including fusing and testing of the system. Please tell me whether you carry out such work and what documents you require for this.

I need to move a light switch a few centimeters because a built-in wardrobe is going to be installed and right now it's in the way. The switch works fine, I just want to move it so it's accessible and doesn't clash with the wardrobe. I would like the installation to be left properly finished and without exposed wires. I would appreciate it if someone could tell me whether any chasing needs to be done or if the existing wiring can be reused.
