These two could probably come off the same power distribution board hanging off a power plant since you’ll only ever use one or the other and not both. Plus, they’re mostly low power usage/requirement components.
Edit: I just noticed you mentioned UK, something similar to the following would work.
You could use one of these plugged into the PowerPlant to extend the outlets, these are just straight parellel receptacles without any filtering. You can buy it assembled or a kit with assembly required. Use it with the power cable of your choosing or make one of your own, and if you make the PC, you can upgrade the internal wire from the IEC to the receptacles. You can leave it basic or trick it out.
Something like this would be a possible solution for me. Unfortunately here in EU I cannot find a Schuko version.
If I’m not wrong a past P12 model had more outlets. Very useful due to lots of components on the market and PS Audio philosophy (separates)… PST, DAC, AirLens and so on. I have 2 P12s and have not enough outlets.
One more thought: also a P15 in EU version has “only” 3 HC outlets - 2 monos and 2 subs would need almost 4 outlets. I would be very happy if next PS PowerPlant in EU version would take this into account.
@Paul do you think is possible to have a P12 with 5 sockets (2 HC) or a P15 with 10 sockets (4 HC) for EU model with Schuko?
