All I can suggest is that you ring the UC Helpline.
Universal Credit helpline
Telephone: 0800 328 5644
Welsh language: 0800 328 1744
NGT text relay – if you cannot hear or speak on the phone: 18001 then 0800 328 5644
Textphone: 0800 328 1344
Monday to Friday, 8am to 6pm
The wrong address could delay your letter by weeks or it might not even get to those who can action it.
