In England and Wales, your landlord or letting agent should tell you which government-approved tenancy deposit scheme holds your deposit and provide the required information within 30 days. You can then search that scheme’s website using your tenancy details, or contact it directly if you are unsure. Rules and schemes differ in Scotland and Northern Ireland, so check the relevant guidance on GOV.UK or your local government website. If your deposit was not protected or the required information was not provided, a housing adviser or solicitor can explain what remedies might be available; any court outcome depends on the circumstances.
