Graphic: private landlords and their tenants

All private landlords would have to be registered before letting residential property under government plans to curb abuses in the growing rental market, The Times has learnt.

Easy access to buy-to-let mortgages over the past decade has meant that the number of private landlords has risen to about one million in England and Wales, and ministers are worried that a growing number of unscrupulous landlords are exploiting tenants.

Anyone letting a residential property would have to pay about £50 to register with a national body. This would include developers, buy-to-let investors and the growing ranks of “accidental landlords” who cannot sell their homes and have been forced to let them out instead.

Registered landlords would have to comply with certain standards and those who fail to carry out repairs or who intimidate tenants could be struck off. If that happened, all their tenants would have to move out, although this would not happen overnight, Whitehall sources suggested.

The reforms are to be outlined in a Green Paper within ten days.

The Government intends for the system to be operated with a “light touch” to improve standards and root out rogue landlords, but the bureaucracy could drive out small buy-to-let investors.

Simon Gordon, of the National Landlords Association, said: “We can see the thinking behind this but we need to see the details and be reassured that this is not simply a mechanism for tougher regulations.”

In Scotland, private landlords are already required to register to let properties. The scheme was brought in after a series of scandals about multiple occupancy. In the first year only 15 per cent of landlords registered, but tougher legislation has since been introduced. Landlords who fail to register can face criminal proceedings and have a notice served on their properties stating that tenants do not have to pay rent.

Although details of how the scheme would work in England and Wales are still being negotiated, one option is that each landlord would be given a licence number that would appear on all documents related to the letting. This could make it easier for the Inland Revenue to identify tax evaders.

The administrative costs are expected to be covered by the licence fee.

The system would be monitored by an independent body to adjudicate complaints made by tenants. If these complaints were upheld the landlord could lose his or her letting licence. Under one option being considered, the Government might set up a “social letting agent” to place affected tenants in more suitable privately rented accommodation.
