Which blurb?
I don't believe this is possible I'm afraid. The only way I know to get lounge access domestically like this would be to book Business UK cash ticket at ~£250 each way!
Theoretically you can get redemptions into U class domestically, but I only think this is possible with a connection to a premium class flight.
