In the UK, landlords are required by law to protect a tenant's deposit under the Government approved Tenancy Deposit Protection Scheme. This requirement is part of the Housing Act 2004 and aims to protect tenants' deposits and ensure fair treatment during the tenancy process. More information can be found in the article on rentola.co.uk. Landlords must deposit the tenant's deposit into the government-approved TDP scheme within 30 days of receiving it. These schemes include the Deposit Protection Service (DPS), MyDeposits and the Tenancy Deposit Scheme (TDS).
