With just a cheap SSD droplet on DigitalOcean or Linode ($5 or $10) managed by a good server administrator like MattW, https://xenforo.com/community/threa...k-server-configuration-hosting-support.61392/ your sites will fly like a rocket.
80 GBP for initial server setup + an extra 15 GBP per month for monthly maintenance? Unfortunately this is something I wouldn't be able to afford. $15 is what I can spend this month and each recurring month.
Could you link to the site here?
Where are your servers from? Am I able to host a XenForo forum, a static site, and a Wordpress blog?
