I have submitted this before, but for those maybe a bit uncomfortable with setting up a VPS to act as an exit node for Wireguard, my article covers most things:
For this particular use case, I would probably suggest something like OVH/Scaleway as they have nodes in France so physical distance between UK and "somewhere else" is low which will affect latency. If you're willing to wait longer and go further, I recommend Infomaniak (Switzerland - they have nodes in Geneva I think/Zurich). Hetzner (a crow favorite) hasn't been that good for me while I was in the UK, I was getting dropped packets even after switching a few VPSes, but might've just been something temporary.
