For the people who open everyone else's post
If you sort out official letters for an elderly parent, someone you care for, or your tenants, you know the feeling: another envelope, another bit of jargon, another deadline you can't afford to miss. OneLetter is built to make that quick.
Whether it's a parent's HMRC or pension letter, a benefits decision for someone you care for, or a council or court letter about a property, you can upload it to OneLetter and get a free plain-English overview in seconds — what it is, whether there's a deadline, and how urgent it really is.

Why it works when you're doing this often
When you're handling someone else's affairs, the hard part usually isn't the reply — it's working out what a letter actually is and how worried to be. OneLetter's free overview gives you that triage in seconds, so you can tell a routine notice from something with a real deadline without reading pages of guidance. When a letter does matter, the Ultra Breakdown lays out exactly what it means and what to do next, in a summary you can keep or forward.
Every explanation is written in plain English and checked against gov.uk guidance, and we link the official source on each page — so if you need to escalate to Citizens Advice, a welfare rights adviser, or a solicitor, you'll know why.
A note on acting for someone else
If you regularly manage another person's money or affairs, it's worth having the right authority in place — such as being an appointee for benefits, or holding a lasting power of attorney. OneLetter helps you understand the letters; for setting up formal authority, gov.uk and Citizens Advice explain your options. Remember OneLetter provides information, not legal advice.
