Shed Wiring

[fobthebuilder]

Hi, I'm looking to add additional sockets and light switches. However, I'm wondering what's the best way to go about it safely without any complications. The trouble is that the wiring leading to all 3 sheds are directly powered from the internal consumer unit in my house, via a single mains wire which connected to the Kitchen Sockets breaker, and not separated.

Diagram with proposal:

Proposal to Shed 3:
- 1x Light Switch with Light
- 2x Plug Sockets
- 1x Junction Box

Going forwards, I may add additional floodlights and sockets on the exterior of the sheds.
Would I need anything else? Maybe an additional consumer unit for the shed to carry to load (if required)?

Any help would be appreciated.
Many thanks

Well for a start I'd suggest that as it originates at the CU, having it on its own MCB/RCBO would be a good idea.
Your electrician will be the best person to ask.
