About Lettr
Why we built it, who we are, and what we believe.
The problem
Across the UK, everyday consumer and tenancy disputes — deposits not returned, private parking charges that don’t obviously hold up, faulty goods refused for refund — often turn on whether the person complaining can write a clear, structured letter that references the right Act. Writing that letter is technically simple but practically intimidating, and a barrier that many people don’t cross alone.
Solicitors charge £200–£500 for a single demand letter. Citizens Advice has waiting lists. Templates online are generic and easy to ignore. So most people give up — and lose money they were entitled to.
What we do
Lettr drafts a structured complaint letter from your facts, with references to the relevant UK statute, in around 60 seconds. The letter is yours — you read it, edit it if you want, and send it. We focus on three everyday consumer/tenant scenarios where a clear, statute-referenced letter is most useful:
- Tenancy deposit disputes (Housing Act 2004 Part 6 Chapter 4 and the Tenant Fees Act 2019);
- Private parking charge appeals (Protection of Freedoms Act 2012, Schedule 4);
- Faulty-goods refunds (Consumer Rights Act 2015, sections 9–11 and 20–24).
Each letter is grounded in actual UK statute relevant to your situation and formatted as a proper business letter. You remain responsible for reviewing the letter and deciding whether to send it. We track the deadline you set and prompt you to consider the next step (a TDP scheme dispute, an independent parking appeal, or a county court small claim) if you don’t hear back.
What we are not
We are not a law firm and we do not provide legal advice. We are not regulated by the Solicitors Regulation Authority, the Bar Standards Board, the Financial Conduct Authority, the Legal Services Board or any other legal regulator. We do not act for you, we do not represent you, we do not conduct litigation on your behalf, and we do not provide any regulated claims-management activity. For complex disputes — anything involving large sums, court proceedings already underway, financial services claims (such as Section 75 of the Consumer Credit Act 1974 or FOS escalations), employment matters, immigration, or specialist areas like family or company law — you should consult a qualified solicitor or contact Citizens Advice. See our disclaimer for the full picture.

How we’re different from free templates
Free letter templates online are generic. They don’t cite the right statute for your specific situation, they don’t adapt the tone to the recipient, and they don’t track your deadline. Recipients see them every day and know how to ignore them. Our letters are bespoke to your facts, properly cited, and properly escalated.
How it works under the hood
We use Anthropic’s Claude (a large language model) combined with a curated corpus of UK statutes and case law. For each Letter, the system retrieves the relevant legal provisions, applies them to your specific facts, and produces a formal draft. Every Letter is backed by verifiable citations.
We are obsessive about not making things up. AI is helpful but it can confabulate; we mitigate this with retrieval-grounded generation, statute verification, and prompts that refuse to invent citations.
Built for the UK
Lettr is operated as a sole trader in the United Kingdom. We host on European infrastructure, keep your data on UK time, and design only for UK law. ICO data-protection registration is in progress and will be completed before scaling beyond initial pilot users.
Our values
- Honesty about limits. We tell you when our Letter is right for your situation, and when you should see a solicitor.
- Verifiable citations. Every legal claim links back to a real statute we can show you.
- Privacy by default. We collect the minimum we need, retain it only as long as legally required, and never sell it.
- Speed without compromise.Fast doesn’t mean sloppy. We test every prompt against real UK legal patterns.
- One price, no upsells.£29 means £29. No surprise fees, no “premium” tiers locked behind dark patterns.
