In September/October i wil be transferring a lump sum approx 32k from a well known pension management company, I have heard some horror stories of people’s monzo accounts being frozen for legitimate large deposits and it being a nightmare to get sorted my question is should i expect something like this to happen.
Ignore the horror stories. They are lies.
ALL banks will do checks on ALL amounts of money that is moved between accounts. A pension provider paying you will be absolutely fine.
Just note that if you wish to transfer out more than £10k at a time you will need to request a limit increase.
Just let Monzo know nearer the time. I did this with mine and no problems.
