There is no separate deposit protection scheme just for young adults. In England and Wales, a landlord or letting agent will usually need to protect a qualifying tenancy deposit in an approved scheme, such as DPS, MyDeposits or TDS, and provide the required information within 30 days. These schemes can help resolve disputes about deductions when the tenancy ends. Rules differ in Scotland and Northern Ireland, so check the relevant guidance on GOV.UK or the devolved government website; if your deposit was not protected, a solicitor regulated by the SRA can explain your options.
