Wiring a garage

[pdg]

Sorry to bring up a recurring subject. I'm currently wiring up my garage. I'm going to run the supply from a spare fuse on the main consumer unit out to the garage to a 2way consumer unit. I'll put in a small lighting circuit and a small power circuit. What I really want to know is how the new electrical regulations (Part P) affect electrical installation for external building like garages and sheds.

Part P building regulations apply, it is also notifiable to LABC.

I know about informing the local building control, but what changes to the electrical installation are there. Someone mentioned to me that a bench level isolation switch separate to the consumer unit is necessary. It might be if i had a workshop but not for a couple of lights and sockets.

If you're running the correct cable for the purpose, properly protected from overcurrent/short-circuit to an RCD controlled garage consumer unit and all your earthing and bonding are up to scratch then that's absolutely fine. The Wiring Regulations have not changed since the second amendment to the Sixteenth Edition, in March 2004.

You do not need emergency isolation switches in the situation you have described.

But Part P (which is part of the Building Regulations) does apply. Your duty here is to comply with all relevant building regulations. Notify, pay the building control fee and let the LABC inspect, or engage a self-certifying electrician.
