Welcome to ice skating; give it a try sometime if you can; everyone starts somewhere.
Also training somewhere cold increases your metabolic rate more.
I've deleted facebook long ago, but there were some groups on there for ice skating.
In terms of non-skating, this is probably dependent on where you are in the country; a good place to start:
https://www.iceskating.org.uk/get-into-ice-skatingRink clubs need volunteers/organisers for regular sessions & seasonal shows.
Competition events; anything from runners, time keeping, music, technical panel.
Having some form of first aid certification might be useful; learning sign language might also be helpful.
If you're handy with a sewing machine, and have an eye for fashion, making new outfits could be an opportunity.
Also some local schools run rink sessions who might need some help with inclusive skaters.
If you're near Slough ->

Hope that helps.
Forgot to add; you could also do music editing & choreography.
