.UK Domain Transfers are possible.

Transfer procedure

In order to transfer a .UK domain to your account you have to complete the following steps:

  • Request a transfer for this domain
command = TransferDomain
domain  =
action  = request
  • You / the domain owner must contact the current registrar for this domain and ask him to change the IPS-Tag of the domain to "KEY-SYSTEMS-DE".

Once the IPS-Tag has been changed the domain will be put on your account.

Transfer notes

  • Please note that when a .UK Domain is transferred successfully, the remaining registration period is kept.
  • Please do not forget to initiate the transfer in the RRPPRoxy, even though your current provider only has to change the REGISTRAR-TAG or the domain will not be put on your account.
  • If the tag is not changed to KEY-SYSTEMS-DE for a domain requested in the RRPProxy, the transfer will timeout after 5 days.
  • A list of registrars and their corresponding IPS Tag can be found here

Transfer time

The exact transfer time is dependent on the current registrar.


Depending if a .UK domains has been detagged or expired, one of the following procedures has to be applied to restore the domain name.

Restore procedure for de-tagged domains

The procedure to re-tag an .UK domain is merely the same as the transfer procedure.

  • Request a transfer for the domain.
command = TransferDomain
domain  =
action  = request
  • The domain owner has to re-tag the domain at the registry. Please note that this is bound to additional costs. Further information about how to re-tag your domain can be found here

Restore procedure for autoexpired or autodeleted domains
