Translate a Formal Letter From an Official Body Into Plain English

The letter is from the council, or HMRC, or your housing association, and it reads like it was written to be taken seriously rather than to be understood. This translates every part of it into plain English, identifies the action required and the deadline, and flags whether you need to speak to anyone before responding.
