Council tenants breaking the law by subletting their homes are being given the chance to hand in their keys in an amnesty.

Anyone sub-letting a council home can be prosecuted under tenancy fraud, but Haringey Council says it will turn a blind eye to anyone who comes forward by December 20.

A change in the law last year means tenancy fraud is now a criminal offence, with a prison sentence or fine of up to £5,000 for those who flout the rules.

Councillor Jason Arthur, cabinet member for resources and culture, said: "Subletting your council flat to make a quick buck is not only illegal, it puts real pressure on the housing system and prevents families in genuine need from finding a home.

"Our key amnesty will give those breaking the law a chance to avoid getting a criminal record and make sure that our housing is being used by those who really need it.

"This is a one-off opportunity to avoid prosecution. Once this amnesty finishes, the council will use every power available to prosecute those who feel they don’t need to play by the rules."

A 2011 Audit Commission report estimated that around 90,000 social homes nationwide were subject to some form of tenancy fraud.

Tenants wishing to take advantage of the amnesty can hand in their keys at either of the council’s customer service centres or their neighbourhood housing office.

The council’s fraud team receives around four tip-offs of illegal sub-lets every week, and works closely with Homes for Haringey and other providers to look into any fraud claims.
