so after been full Monzo since Jan 2018, I didn’t fully closed my other account, just did a partial switch all DD and SO, I even had my salary paid in my Monzo ACC, so a few days ago I got an email from my old bank (MetroBank) stating they’re going to close my account after a review, my financial well-being hasn’t changed negatively only improve not much but it’s ok and I haven’t applied for anything this year other than Monzo, I’ve been with MetroBank for 8 years, they gave me three months to close my account, said I need to make other banking arrangements, I’m wondering if their closing it because I haven’t used it since I switched out everything from them, I’m not really bothered they are closing it but if this is the way they deal with Thier customers I don’t want to be part of that, thank god for Monzo bank of the future 
I have had a bank account with Co-Op for over 8years and never used for at least 6 
its still open
that’s good yours is still open, strange though mine got closed, well will be closed in Feb, I didn’t even called to ask why they are closing it
Might be hurting your credit having a dormant account?
Actually, having a long–standing account is a positive sign for lenders. It shows stability.
Doesnt matter litterally completed bankruptcy yesterday, as I have a disabled son with a life limiting condition, we had a flat that we had to volentary surrender as couldn’t afford to keep it going whilst trying to sell it while waiting for Housing Assocation for a purpose diability flat/house we would have been trying to pay £1200 a month for the mortage and HA rent on one salary was never going to work. So only way up now.
That’s really shit 
Glad you’re trying to think positively
only option you got
The very best to you @Juggy69
