That sounds reasonable... however, if banks are not allowing cash deposits into personal accounts anymore (as someone said here), having several accounts in different banks is not solving the problem (unless of course one of those accounts is a business on where cash deposits are allowed). In my case I file taxes as a sole trader (no company) and have one account (personal), I've been depositing my earning the last day day of each month for years religiously. Last time I did this I was thoroughly interrogated as to were my cash deposit came from. I thought it was weird (they've never asked me anything all these years), so I'm thinking in opeing a business account with another bank.

Has to be the account holder, have you thought about using ATM pay in - a few banks offer this, and or the post office? Many banks can be paid into at the post office.

It’s an option.

You were wanting to avoid being questioned or advised into a business account? ATM pay in doesn't involve bank staff, there are automatic paying in machines inside branches, as well as the ones outside which if they are working are accessible 24 hours a day.

Post Office aren't interested in your account just taking the cash and doing the transaction, quite a few businesses use the PO. I have to because most bank branches have closed locally some shop based POs have longer hours than actual branches. Basically they are doing their job whereas bank staff are often trained to sell other products.
