Landlords should be put on notice that they must bring their properties up to a decent standard or have these homes banned from the market by 2025.

This is one of a number of proposals put forward today in a new report on the London market.

The report says that all boroughs should be allowed to set up their own licensing schemes, and be able to use the fees to increase enforcement activity.

The London Housing Commission, which issued the report, argues that London needs a “radical devolution” deal if it is to solve its housing crisis.

In return for greater powers over borrowing, property taxes and planning, the Mayor and boroughs would have to make a joint commitment to deliver significantly higher numbers of new homes.”

The report says that London should be able to retain a substantial portion of Stamp Duty Land Tax money, to fund the building of new homes.

Lord Kerslake, chairman of the London Housing Commission, said: “London is facing a housing crisis of unprecedented proportions brought about by a chronic under-supply of new housing. It needs urgently to be building far more houses of all types and tenures.”

Jeremy Blackburn, head of policy at the RICS, said: “There is no doubt that London faces a housing crisis. As we have always said, the solution relies on all parts of the housing sector ‘firing on all cylinders’ to deliver all kinds of new homes from Government-funded social housing to private new builds.

“Critically, new and replacement social homes must have protection from Right to Buy in London.”

He added: “Though we agree with the London Housing Commission that poor quality homes and rogue landlords need to be addressed, the introduction of individual licensing schemes for each borough would place additional regulatory burdens on landlords and local authorities.

“They would also penalise those that are providing a good service, creating a fractured regulatory framework and hindering institutional investment in the private rented sector.”
