If you are being made redundant the prudent thing to do would be to lodge it to a easy access deposit account that pays some form of interest. You may have a whole pile of expenses that need to be paid in the interim while you get a job. I would park the redundancy money in an another bank to the ones you owe the mortgage to. If its more than 100k split it to keep it safe from 'bail ins' or just make it a joint account which has 200k cover.
