The supply to the building will be separate from your house consumer unit. We install a switch fuse at the mains and run an armoured cable to the build, each build typically has a 32 amp supply.
The building will have its own RCD consumer unit.
Once again as these builds are bespoke, the power requirements inside the build are up to you LED Down lights, LED strip lights, lamp circuits, sockets in any location, remote lighting circuits etc the potential is endless.
We also include as standard a hard wired internet link.
Extras would be alarm systems
speakers in the ceilings, CCTV and remote lighting.
