At stage two: the Pensions Service decides eligibility for pension credits according to the relevant regulations; Citizens Advice Direct checks the eligibility of younger households for benefits and advises them how to apply, but it is up to the household to apply to the relevant agency, which decides eligibility (such as HM Revenue and Customs for tax credits, to Job Centre Plus or the Department of Work and Pensions for income support and other benefits, or to the local authority for housing benefit or reduction in council tax); energy suppliers decide whether households are eligible for a social tariff according to their own guidelines.
