I am doing a new build and want to locate the suppliers cut-out and
meter in the garage but have the consumer unit in the house. The
distance from the Meter to the Consumer Unit (CU) is about 15M.

What I want to do is install a breaker on my side of the meter in the
garage and run an armoured cable underground to the house and consumer
unit. Is this permissible.

There is no indication in the On-site Guide although it does show the
possibility of a main switch between the meter and the CU. I have also
heard that there is a limit of 5M on 'tails' but again the On-site Guide
does not mention this.

Thanks, Brian
