Hi spitfire77
Your question is not a question we can answer as we do not have all the facts, We would advise you to seek help from your local Welfare Rights Specialist; you can find your local Welfare Rights Organisation to help you with advice by clicking on the link below and putting in your post code, it will then come up with a MAP with a list of agencies in your area
advicelocal.uk From your post you state that you were in receipt of IR ESA and CB ESA, what usually happens when you apply for UC, you lose the IR ESA, this becomes UC and CB ESA turns into NS ESA. UC will deduct NS ESA payments £ for £.
