How to send your letter
- 1
Write your request
State clearly that this is a Freedom of Information (FOI) request and describe the records you want as specifically as you can — dates, names, file or reference numbers, and the office or program area, if you know them. Vague requests take longer to process.
- 2
Include what they need to identify you
If you're requesting your own file, include your full name and any identifying number the institution uses (case, claim, or file number) so they can locate the right record. Most FOI requests are free; a public authority can refuse or charge if the cost of finding and extracting the information would exceed the statutory limit (usually £450, or £600 for central government).
