naturalization invitation letter from home office ?

Date of Application- May 1st (self-post)
Date of Approval- 23 July
Date of Received- 25th July by special delivery .

In letter they said ...pleased to say that application successful. And you will receive a letter inviting you to attend ceremony. And this is not an invitation letter. You should not contact local authority until you have received your invitation. If not received invitation within 2 weeks you should email.

Now my question is who gonna send me invitation letter. Home office or council ? Please advise me. I know one letter will come from council for book appointment with them for ceremony. But another letter will come from home office for invitation ? Please lete know.

you will get a letter from the Home office advising you to call your council to book an appointment for the ceremony. The letter from the home office indicates that your certificate has been sent to your local council which will then go ahead to officially confirm you as a British citizen. You need to wait for the home office to write to you not your council.
