Will the installer need access inside my home?

In most cases, yes, though it ultimately depends on your home's layout and electrical setup.

The installer will likely need internal access to:

• Locate your electrical components: They may need to work on or inspect your fuse board (consumer unit), meter, or main electrical supply if they are located indoors.
• Plan the installation: They need to map out the safest and most efficient path for any new cabling.

What if everything is outside? If your meter and consumer unit are entirely outdoors, the installer may not need to spend much time inside, if any.
