Best UK hosting provider

Hi, im very new to Jitsi and am using it to try and help isolation problems between me and my family at this time. As a spinoff to this I let other friends try it and after around 100 users on 14 different rooms the server started struggling. Im currently looking at building a containerised install to help, does anyone have any UK hosting providers they recommend for this. I would usually test services but im trying to build this asap so I can keep communication going between friends and family.
