@JakTheBiscuit assuming its a .uk domain, then you need the IPSTAG changing to that of your chosen new registrar.
If its not a .uk then you need an EPP code.
Either way, if you post a request on here then a staff member should pick it up and raise a 'ticket' for you to securely reply with the details.
Normally, to avoid any donwtime, the transfer process is to change the DNS records on the current nameservers and then when the TTL has elapsed , switch nameservers . See the excellent transfer guide here https://www.mythic-beasts.com/support/domains/transfer-no-downtime ( note its not Mythic exclusive, the mechanism applies to any hosting )
However, its not possible to change the DNS records on the PLusnet control panel, you need to transfer the registration first and then switch nameservers and accept that there will be a period of transition, where mail could go to either old or new hosting.
Don't forget that, if use use IMAP to access your email, then you need to transfer existing emails from PLusnet to the new hosting!.
I used Imapsync to transfer mine https://imapsync.lamiral.info/ . There's a free online version but I actually installed it on a Linux system.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.
