A spokesperson for the Department for Work and Pensions said the welfare reforms were designed to simplify the benefits system and make it easier for people to get back into work where possible.
The "Bedroom Tax" is designed to bring the social housing sector in line with the private system.
The Government believes it is unfair that some people are living in homes that are too big for them whilst other families are having to live in overcrowded properties.
It says there is currently a long waiting list for social housing.
