As of 13 August 2026, AI can complain about an unreturned rental deposit.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open GOV.UK guidance for tenancy deposits and note which UK nation, deposit scheme and complaint route apply to your tenancy.
   2. Gather the tenancy agreement, deposit payment record, scheme certificate, check-in and check-out reports, photographs, proposed deductions, invoices and all messages with the landlord or agent.
   3. Write a dated timeline of the tenancy ending, the deposit request, replies received and any deductions proposed, then redact bank details, identity numbers and unrelated personal information.
   4. Paste the timeline and relevant extracts into an AI chat with the prompt, stating the country, deposit amount, recipient and outcome you want.
   5. Check the draft line by line against the agreement, correspondence and evidence, correcting every name, date, amount, quotation and claim that is not supported.
   6. Compare the proposed recipient, escalation route and deadline against the current GOV.UK guidance and the deposit scheme's own instructions.
   7. Send the checked complaint through a traceable channel, attach the relevant evidence, keep a copy and record the date sent.

   Prompt

   Help me draft a factual complaint about an unreturned rental deposit in the UK. First identify which UK nation applies: [England, Wales, Scotland or Northern Ireland]. Do not give professional advice, guess the law, invent facts, or state a deadline unless it is supported by the documents or an official source I provide. Do not decide who is legally right. Use only the information below.
   
   Tenancy and deposit details:
   [Paste the relevant tenancy agreement clauses, deposit amount, payment date, property address with personal details redacted, tenancy start and end dates, and any deposit scheme information.]
   
   Timeline:
   [Set out the key dates in order.]
   
   Evidence and correspondence:
   [Paste relevant messages, emails, check-out records, invoices, photographs and proposed deductions, with unnecessary personal data redacted.]
   
   What I want:
   [For example, return of the undisputed deposit, an itemised explanation, or evidence supporting deductions.]
   
   Produce:
   1. A short summary of the dispute and the points that are supported by evidence.
   2. A firm, polite complaint to the correct recipient, without threats or unsupported legal claims.
   3. A numbered schedule of disputed deductions, amounts and evidence.
   4. A list of missing information or documents.
   5. A separate list of statements I must check against current GOV.UK guidance, the relevant deposit scheme or another official source before sending.
   6. Practical next steps, clearly labelled as general information rather than professional advice.
   Keep every date, amount, name and quotation tied to the material supplied. If the correct recipient or escalation route is unclear, say so and ask a question instead of guessing.
