Wiring In a Shed, advice needed on SWA route

Could also use one of these to get internet into shed.

NEVER use those things. They cause serious interference to other users of the RF spectrum, possibly including air traffic control.

The Likelihood and Extent of Radio Frequency Interference from In-Home PLT Devices

PLT devices operate between 2 and 32MHz, with some emerging devices operating at frequencies up to 300MHz. We commissioned a study to estimate the likelihood and extent of interference to various services over the coming 10 years.

Total length is around 20 meters for the cable route.
Anyway, the volt drop would be negligible. Also it’s going to go under the wooden floor and not encapsulated in insulation or plaster.
I know I probably don’t have to run 6mm2, but it’s just if I end up running something a bit heavier than a couple of computers and the lights

If you are allowing for a higher load in the future you need to calculate volt drop based on the higher load.
