Incapacity benefit will I still bring back it even if I receive a monthly insurance allowance Worth around lb13000 p/a?



Answers:   Maybe - as far as I can tell, it's not finances tested .. ask the Job Center ...

NB. If the payment is compensation for some injury that cause you to claim IB in the first place, you can be sure the Job Center will be after you to reclaim adjectives the IB paid out since the injury ..
No you won't be entitled to benefits if you are unloading that amount xxx I very much doubt it, If you do claim it anyway, and they find out, YOUR NICKED.
