After you move out, you need to send an email to the landlord, formally asking them to return your deposit. The landlord can then open a discussion about potential deductions. If you both agree on the amount, you can let your landlord notify the deposit protection scheme. If you can't agree on the amount, you will have the contact details for the scheme in your prescribed information, that the landlord served as part of the deposit protection. You can raise a dispute with them and follow up on the procedures they describe. If you know that your deposit is not properly protected, you already know what you need to do.
