If you wish to keep the domain where it is but just want us to have technical control over the domain then just change the name servers to the following:

ns1.hostingwizard.co.uk
ns2.hostingwizard.co.uk

Please do get in contact with us before changing these to make sure that everything is set up on our servers.

Extra Information:
As your leaving the domain where it is you will need to renewal the domain with them and not us.
Changing name server still can take up to 24-72 hours propagation.
