Check your tenancy agreement for the correct notice period, and give notice in writing; the rules depend on your tenancy type and circumstances. Before leaving, take dated photos, complete the inventory, report any damage, record meter readings, return all keys and provide a forwarding address. Your landlord should normally use the agreed deposit-protection process, and can only propose deductions for justified costs rather than ordinary wear and tear. Also arrange final bills, council tax and mail redirection, and keep copies of your notice and messages; check GOV.UK or speak to a housing adviser if you are unsure about your rights.
