Opening new NISA while keeping old NISA

I have done some research on this but find conflicting answers, so excuse my confusion. If I want to start investing through NISA at a new bank/broker from the one I have used until now, can I just open a new account at the new bank/broker for say year 2026, whereas the already invested NISA accounts from year 2025 and earlier stay stay active at the old bank/broker?

My understanding that this is fine since each year is treated as a separate NISA account. Only having multiple NISA banks/brokers in the same year is not possible. Is this correct?

Thank you!
