Sorry for the late response, my MN notifications seem to be a bit hit and miss at the moment!
I started competing fairly early on in my journey. For local competitions you don't need a qualifying total or any sort of experience, as long as you can lift at least the empty bar + the collars (so 25kg) and you're able to follow the referees' commands, then anyone can join in!
I am not competitive by nature and I wasn't sure whether I would enjoy it at first, but I absolutely love competitions! Mostly because although there is a winner, it really is more about improving on your own PBs and lifters are really supportive of each other. I always make new friends on comp day! It's also really cool that you lift alongside women of all levels, from total beginners to international athletes, and I usually pick up a few handy tips from the more accomplished ladies.
My Dsis is into marathon running and it seems to be a similar ethos as that, unless you're elite level you don't really enter to win, and everyone is friendly and helpful.
I would recommend joining the British Powerlifting FB group, people there will be able to direct you to your local federation and affiliated clubs (although you don't have to join a club, but may want to if there is one near you), then COVID permitting you may be able to go watch the next local competition and get a feel for it
