Garage electrics

I want to replace all electrics in garage. The power to from bungalow from 15, amp wired fuse to garage CU type b rcb fuses I think, that trip when you sneeze, only joking!
Garage:
4 13amp sockets (ring) one on separate fuse powering two freezers.. Three strip lights. A mess of cable.
Want to subject to advice run new as radial cable roof level and drop to each socket a single cable from radial cable. Max load at any one time would be 6.5amp+2 strip 3ft lights an two freezers on their own fuse in C.U.
As the amps will be well within 13amp max I can't see problem
Am competent and know elecs take no prisoners,
I rewired lighting added sockets In our London house including new CU many moons ago and it was officially passed, done before new regs, things changed, like addition of bonding,....No!no! I don't mean chains, handcuffs, whips, leather garb and bed bonding, I mean EARTH bonding.
I await your responses before any work starts
Thank you for your advice in advance.
