[QUOTE="Doc Hudson, post: 466734, member: 1607"] If you connect your new cable from your external socket to the existing 16A socket MCB already supplying the garage sockets then technically you are extending an exiting circuit which is NOT notifiable. But if you connect the very same cable onto a new MCB then technically it is a new circuit which IS notifiable. One of the stupid anomalies of the Part-P fiasco. However irrespective of notifiable or not, ALL electrical work should be correctly designed, installed and tested in accordance with BS7671 wiring regulations, to verify ALL safety protective devices will operate fast enough in the event of a fault to prevent killing anyone in under a second. Your description of the RCD only relates to the maximum power it can safely disconnect, you do not mention its tripping current, which should be 30ma? The tripping times of this RCD will need to be tested along with the earth loop impedance to verify the overload protection of the MCB's will also operate quick enough. If you do not have access to, and knowledge of how to use, Earth-Loop-Impedance Testers, and RCD testers, etc. then I would just leave it to a competent person to undertake the work for you. . Especially as all external wiring has added dangers where you export power outside of the equipotential zone. if you get it wrong you or your loved ones could be dead very quickly.
