The Single Fraud Investigation Service (SFIS) is responsible for investigating fraud. It is part of the Department for Work and Pensions (DWP).
It investigates and prosecutes Social Security welfare benefits fraud (including Housing Benefit but not Council Tax Support) and Tax Credit fraud across Local Authorities, HM Revenue & Customs (HMRC) and the DWP.

You can report suspected Housing Benefit fraud in three ways:

  • By telephone: contact the National Benefit Fraud Hotline on 0800 854 440. Your call is free and confidential you do not have to give your name or address. Lines are open Monday to Friday 8am to 6pm.    

 If you have speech or hearing problems you can use a text phone service on 0800 328 0512 or Welsh speakers can call on 0800 678 3722.


 Some typical examples of benefit fraud are:

  • people who are working but do not declare this when they claim benefit
  • people who claim as a single person, but actually live with a partner
  • people who claim from an address but do not actually live there
  • people who do not tell us the full amount of income, savings, pensions or capital when they claim benefit
  • landlords who continue to get benefit paid directly to them after the claimant has left
  • people who do not declare other adults living in the property
  • people who deliberately and dishonestly do not tell us about a change in their circumstances which would reduce their benefit
