As I'm sure you're aware, social security benefits in Northern Ireland are dealt with by your
Department of Social Welfare , as opposed to the rest of the UK where benefits are administered by the Dept of Work and Pensions.
Northern Ireland covers an area of nearly 5,500 square miles, so for moderators it would be impossible to provide the information you are requesting.

www.nidirect.gov.uk/benefits-adviser if that doesn't help then the best way to find out would be to Google : benefits advisers in x Northern Ireland, where x = the name of the county or town in which you live in Northern Ireland.
