And just for good measure, this is what HM Treasury said in a recent consultation document:
The Private Rented Sector (PRS) plays a critical role within the housing system, helping to meet growing demand and providing a flexible tenure choice. It has also played a disproportionate role in funding new-build supply in recent years. It is important that the sector continues to grow and develop to help meet the housing challenge, and that it is able to respond effectively to changing demand.
It is clear that the level of investment directed by individuals and institutions into the PRS will be key to its future development, and will strongly influence both the volume and quality of supply.
As the housing market recovers, we need to ensure a strong supply-side response to support the recovery. The PRS is an integral part of this - a key issue will be how well the sector responds to changing demand, and the level of investment directed by individuals and institutions into the sector will be crucial to that.
So, is that clear? No PRS, no new building of affordable homes. We need it more than they need us. There are plenty of other investment vehicles which don't involve providing homes for people who can't afford their own.
The (current) govt's response to the consultation:
The Government believes that the best way of supporting the Private Rental Sector is to restore confidence in the economy, stimulate investment, and maintain a stable financial system that supports lending and the long-term growth of the economy.
In other words, there is absolutely no way in the world this or any other govt will try to impose rent controls or any other controls on the PRS. There will be no change to the policy of encouraging investment, tax levels will be left alone, and people should be encouraged to "rent-a-room" to provide more "affordable" accommodation.
