Re-enable an old domain

[#1]

Many years ago I had a domain registered hps.org.uk . It was allowed to lapse. I would now like to be able to use it again. WHOIS shows is as active, Plusnet Plc t/a Madasafish Broadband as the registrar, however it does not resolve in DNS, so I suspect it is not actually in use but was never fully released. How can I go about getting hold of it again?

It's something we'll be able to sort for you. 

Do you happen to know the account credentials (username and password) where the domain is held? 

If so, let me know your username (PM) and I'll create a ticket for you. I'll need the IPS tag of the new host. 

EDIT: I've located the account and created ticket 255187563. If you could please log into the MAAF portal and reply with the IPS tag, I'll arrange the change for you.
