The government's so-called 'bedroom tax', due to come into force from April, will affect around 660,000 social housing tenants across the country.
Under the plans those living in social housing who are deemed to have a spare bedroom will be asked to downsize or face a cut in benefits. Tenants in social housing will have their benefit reduced by 14% if they have a spare bedroom, or 25% if they have two or more extra rooms.
The government says the proposals will save money and help deal with a housing shortage by encouraging people to move out of homes that are too big for them, but Labour and campaigners say the changes will hit vulnerable people the hardest.
ITV News has been highlighting the impact the changes will have on people across the UK, and many families have come forward to share their stories.
