Criminal landlords and unscrupulous letting agents in London will soon be named and shamed in an online database.

All 33 London boroughs have signed up to a rogue landlord checker, which lists landlords and letting agents who have been prosecuted for housing offences, enabling renters to check up on them.

The platform, which launched last autumn, will now obtain information from councils across London.

Newham, Brent, Camden, Southwark, Kingston and Sutton initially signed up to the scheme, which was first announced by the mayor of London, Sadiq Khan, just over a year ago.

The Residential Landlords Association's director, Carrie Kus, welcomed the move.

She said: “We all want to see criminal landlords rooted out of the rental market completely.

“It is good news therefore that the Mayor’s database of rogue landlords is now in operation across the whole of London.

"This will give tenants the support they need to properly distinguish between the majority of law-abiding and decent landlords and those landlords who bring the sector into disrepute.”

The Mayor believes the database, published on the City Hall website, will give Londoners greater confidence in renting a home, as well as acting as a clear deterrent to what the authority itself describes as the ‘small minority’ of landlords and letting agents who behave dishonestly.

He said: “I'm confident this will be a major step in tackling unscrupulous and illegal practices in the rented sector."

As well as attempts to improve conditions in the private rented sector, he also launched a property portal on City Hall’s website, which advertises affordable homes on the rental and sales market in the capital.

“I refuse to stand by as thousands of Londoners suffer sky-high rents and horrendous living conditions in a city they call home,” he said at the time of the launch.
