Hi @Anonymous User
You need to phone the NowTV Broadband Team.
Under My Account > Broadband & Calls whilst logged in on here, there should be a section called Moving Home (keep clicking on it until a telephone number appears on your screen).
Some more further information in the linked article below about Moving Home with your NowTV Broadband & Telephone service.
