Text telling me I'm getting PIP

Hi there, I got a text just after 8 this morning telling me I've been awarded PIP and it'll be in my bank account within 2 weeks, so I am over the moon! I only had my assessment last Wednesday. I presume I'll get a letter soon telling me what I've been awarded. Any idea how long this is likely to take, especially with the Christmas post?

Congratulations.

The text should be sent around the time the letter is being typed up so you might get a letter before next Friday 24th. Otherwise it should be with you by the following Thursday before you get the payment.
Perhaps you'll give us a little more detail once you get it.
