Some grey areas here I think?
Just having a read for Knowsley council
Installing an additional light not notifiable except bathroom etc
installing/upgrading bonding not notifiable except bathroom etc
replacing damaged cable in circuit not notifiable....(for certain conditions) except bathroom etc
Now I know none of these are exactly the same as the original question but surely if all of this is not notifiable then maybe the light swap is not notifiable or is it .....I suppose only the local BCO could answer that.....
Cable is not damaged, it has no earth in it so it is a new cable so will it not be notifiable?
