GOV.UK does not set a single minimum bank balance for all Standard Visitor applications. The financial assessment depends on the length of the visit, accommodation, transport, everyday spending, existing commitments and any eligible third-party support. Another applicant's balance is therefore not a reliable threshold for your circumstances. Start with a realistic estimate of the proposed trip and explain which accessible resources will cover it. The source of the money and your ability to use it matter alongside the balance itself.
