Hi maureens
Welcome to the forum.
You might want to have a look at the following FAQ which explains where everything is;
www.benefitsandwork.co.uk/guides-for-claimants/faq/forum .
It is hard to answer your question as we do not have all the facts, quite often ESA claimants receive both IR & CB ESA without knowing, the IR ESA part the claimant can claim UC, the CB ESA part the claimant will receive NS ESA which will be deducted £ for £ from their UC award.
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
