I think I understand what you mean...
If you have a 15A fuse with a 2.5mm cable you can put 2 double sockets then a fused connection unit (previously called a fused spur with a 5A fuse in to supply a light wired in 1mm cable.
As this is not a new circuit and the garage is integral with the house it does not require 'part-p' notification to local authority.
