When renting a house in England, the landlord asked me to write a bank statement for him. What is this?

Hello, I'm glad to answer your question.

A bank statement is a bank statement (running account). If you have a local bank card in the UK, just go to the corresponding bank and directly tell the staff to open a bank statement, usually in the first three months.

I hope my answer can help you, and I hope it will be adopted.
