There is no set list of documents which should be provided as this varies depending on the type of visa that you are applying for. The visa application form supporting documents checklists list the documents most commonly asked for.

Please contact the visa application centre or visa section overseas where you intend to make your application for a full list of documents which you may have to provide there.

We strongly recommend that you do not buy a non-refundable ticket or confirm travel arrangements to come to the UK, until your visa application has been approved and you have received your visa.
