Default Best electrical layout

Hi All,

I have an existing feed to an outside area - SWA 20mm outside diameter, protected by 20amp trip switch. At the moment this is terminated with a single double socket. I want to add the following
2 x double sockets
4 x outside lights (2 of which will be on the same switch)

I am currently planning the wiring layout and wanted to get your views....

My plan was to take a feed from the current socket (2.5mm Hi-tuff) into a junction box and essentially use this as the supply for the new stuff. Essentially splitting this into 2 circuits.

The sockets are using 2.5mm Hi-tuff and the lights 1.5mm. So now the questions.

1. Is the 2.5mm cable to the junction box ok? The whole circuit is protected by 20amp fuse but in theory this could be increased in the future.

2. Should I put the 2 sockets on a little ring or just connected them radially from the source. Adding the existing one to the ring would be a bit tricky as I would need to get the SWA and 2 x 2.5mm in the socket holes.

3. For the lighting circuit, I guess I have 2 options.
a) take the mains supply to the switches (all 3 are together) and then connect it to the 3 switches taking the neutral and switched lives off to the lights themselves
b) bring the switch and light cables all back into the junction box and then connect it all there.
Anyone have a view on the best option? b) seems more flexible but getting all this in a junction boxes with sufficient knock outs might be challenging

4) on the supply side there is one supply but then several feeds out. Using terminal connectors would be a bit of a pain. Does anyone know of a 1 to many connector. Almost like a sealed version of an earth block - one for live and one for neutral. If you see what I mean?

Thanks in advance for your help

Lee.
