A nice little calculator for you.
Don't forget, you WILL NOT be payed benefit during any notice period, if you have been paid in leu of notice. Redundancy payments can affect the amount of benefits you get, having saving of more than 4k is a problem, however you can pay down debt, to reduce you savings level.
Best thing to do is get that CV sorted, find another job and move before they make you redundant it is much easier to find a job when you have one... I know I have spent much time in and out of employment. If it looks like they want you to stop till the end... tell them you want 3 months "bonus" for working to their timescale, thats what I did with my previous employer.
