I was under the underestanding, it took several weeks for a new member is announced before their actual appointment in the House of Lords, then a title has to be agreed and legal documents must be prepared.
From what I have seen king Charles has hastily-awarded life peerage, handing him the “dignity of a Barony of the United Kingdom for life” enabling him to enter the Lords and swiftly take up the cabinet role.
Crooks, all of them!
