Hi James, this could be powered either way. A circuit run from the consumer unit would be preferable though for best practice, and to minimise inconvenience in case of a fault. If running from an existing circuit in your house, the length of cable might need looking at for voltage drop and earth fault loop values. You also need to consider how to route the cable down the garden whichever method is used. It is preferable to use SWA cable buried at least 450mm deep underground with marker warning tape 150mm deep

The ideal solution would be to run a supply cable preferably SWA type cable direct from the fuseboard via its own mcb to the fuseboard in the garden office. The fuseboard in the office should be rcd protected and from that garden office board you can add your office lights and sockets.. To spur from a socket would mean that you would have to fit a 13amp switched fuse spur and then run SWA cable to the shed. It is best fed direct from the main fuseboard. I trust this assists you.

You should run a separate supply and control from the main incomer.

Hi, you need an independent supply from your consumer unit to your garden office,you will also need to you appropriate cable (armoured).
