You can follow up with HMRC on your application in two ways: 

HMRC can take up to 6 weeks to respond to an Advance Assurance or Compliance application (though this is usually much quicker). If you haven't heard back, here's how to follow up. 

1. By email

The best way to contact HMRC to follow up with your application is by reaching out to the same email the application was originally sent to. 

The email address is [email protected].

Please note that HMRC may take up to 2 weeks to reply to follow ups. 

2. By phone

Alternatively, HMRC also have a telephone answering machine! (This is no longer a direct line). You can leave a message, and they will determine whether a call back is needed. 

The phone number is 0300 123 1083.

Please note, we generally see that emails are replied to faster than phone messages.
