Loft conversion wiring options

[paul64]

Still on with my loft conversion. Whilst I have all plaster removed and floorboards up, I want to route some cable for the sockets to the loft. I have attached two options for wiring to the sockets. Are both OK? Apologies for the quality of the drawing, but it is not a bad attempt considering it is done in Word then pasted into paint.

Since you asked. A ring circuit MUST be one complete ring. It can have spurs off of it but it CANNOT have a full parallel circuit as shown in Option 1.
Option 2 is correct. Do not forget that a new circuit or an addition to a circuit like this is notifiable!! You are not allowed to DIY this type of modification to your wiring. Sorry mate!

Do we really need this post twice?

Do not forget that a new circuit or an addition to a circuit like this is notifiable!!

Whilst starting a new circuit from the CU is notifiable, an an extension to an existing circuit is OK as long as it's not supplying "a special location" i.e kitchen, bathroom or outside.

You are not allowed to DIY this type of modification to your wiring. Sorry mate!

This is a commom misconception. There is no restriction on DIY electrical work, you just have to notify the LABC before you start and have them inspect it.

Is it not possible to give the loft its own ring & RCD/MCB ? (RCCB)
