You’ll usually need your name, address, date of birth, National Insurance number and a valid form of identification, such as a passport or driving licence. The provider may carry out electronic identity checks and ask for your UK bank details to fund the account. Before applying, check the interest rate, access rules, minimum deposit, fees and whether the provider is covered by the Financial Services Compensation Scheme (FSCS). Make sure the account suits your circumstances and verify the provider is authorised by the FCA using its official register.
