What can I use to prove my address as a digital nomad without a utility bill or rental agreement?

The inquiry revolves around proving one's address for visa applications when traditional documents like utility bills or rental agreements are unavailable. The individual seeking help, a UK citizen applying from London, has provided bank statements showing their UK address but lacks other required documentation. In the comments, several suggestions are made, including having parents write a rental agreement, using mobile phone bills, bank letters, credit card statements, or any official correspondence containing their name and address as alternatives.
