Nominet.uk (the registry behind
.co.uk) do not have any explicit terms on transfers of
.co.uk domains, unless the domain is “expired” or “suspended” (from 30 days after expiry, lasts for 60 days). Domains in these statuses would need to be renewed prior to them being transferred.
From the .UK Registry-Registrar Agreement 26 May 2020, section B.1.15:
You may not transfer a domain name during the expiry period, except as set out in paragraph E.3.6
However, some registrars do seem to enforce a 60 day limit on transfers, for example GoDaddy’s rules on transferring out state:
You won’t be able to transfer your domain away if it’s within 60 days of registration or a previous transfer, if a 60-day lock was applied after updating domain contact information, or if your domain has Ownership Protection.
Note Option showing disabled? You can’t transfer your domain if it’s within 60 days of registration or a previous transfer, if a 60-day lock was applied after updating domain contact information, or if your domain has Ownership Protection.
Fasthosts also state:
You can transfer .co.uk, .uk, .org.uk, .ltd.uk, .me.uk and .plc.uk domain names away from Fasthosts, provided that the domain name has been registered for at least 60 days.
Which seems to imply that you can transfer a domain within 60 days of another transfer, but not from the initial registration.
However, other registrars, such as namecheap will follow the registry guidelines and allow for immediate transfers.
