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).
