What financial documents are required for a UK Standard Visitor visa?

Per the comment from pnuts (to whom thanks), there's little to be done except signpost you to the Supporting Documents Guide, which says...

...the emphasis being on the phrase "clearly show that you have access" (see My application was refused due to 'lack of evidence of funds', are there hidden requirements for UK visa applications? for why).

However...

As you are being sponsored by your father, there is a slight possibility to strengthen your application by including evidence of his previous sponsorship, especially if your father has contributed to the costs of your education. This could help to show the strength of family ties. If he has previously sponsored siblings, this could also be helpful. Evidence would take the form of bank statements that contain wire transfers or similar remittances. Note that this is a totally optional step that may give a slight advantage; if you decide to include it, be sure to segregate it in your evidence and to conspicuously label it as "evidence of previous sponsorship" so that it is not confounded with your father's current financial standing.

You are being asked for financial documents for several different reasons.

• You demonstrate that you can afford the cost of the travel. If you don't have enough for that, you haven't thought your plans through properly.
• You demonstrate that you can reasonably afford the expenses. This supports the premise of your travel as tourism and not illegal immigration. An illegal immigrant might borrow money to travel, or the entire family pools their savings to send one youth abroad.
• You demonstrate ties to your home country. That makes it more likely that you will leave again.

Since your father is paying for everything, only the first two points can be supported by financial documents. You need to make clear that he can afford to give you the money, as a gift and not as an investment.
