UK Housing Crisis: How Laws and Policies Are Choking Housing Supply

Yes, there is a housing crisis across the developed world, but no, not every country has faced the same outcomes as the UK. If compared to EU counterparts in terms of population and economy, the UK is missing 4 million homes. That is a backlog of 4 million homes! In my last blog post, I discussed the scale and far-reaching implications of these unbuilt homes and the subsequent soaring unaffordability of housing costs in the UK. Now, let’s dive into the reasons behind the UK's abysmal housing supply.

The Town and Country Planning Act (1947)

Let’s turn back time, shall we? The year was 1947, the UK, like other European countries, was rebuilding houses after the destruction of World War II. The UK introduced the Town and Country Planning Act 1947 (TCPA), establishing a discretionary planning system and along with it several unintended consequences. Under this act, the development of any land was banned unless a permit was granted. Even if guidelines were followed to the T, an application to develop the land could be rejected by any of the concerned officials from central government planning inspectors to local councillors in the planning committee, or even the Secretary of State. So even if the central government wanted to increase housebuilding (which they did), the local government had the power to strike down such plans (which they did).

While the TCPA was initially enacted to limit the urban sprawl from excessively extending into the greenbelt, it made development virtually impossible. In fact, the green belt expanded from 693,000 hectares in 1968 to almost 1,600,000 hectares in 1984, covering 12% of England’s land surface. This severely reduced the land available for housing. Furthermore, this act gave momentum to the NIMBY (Not In My Backyard) movement, the coined term for organized resistance to development, often led by lobbyists wielding significant resources and political power. As Prof. Mark Pennington highlighted,  

Evidence from the local planning process suggests that over 60 per cent of the changes brought about by the process of public participation result in a reduction in the amount of development proposed.

It doesn’t take an economist to deduce what happens to a rigid planning system that restricts housing supply, while demand continues to grow, especially in the Southeast. This scarcity drives up land prices and housebuilding costs, encouraging strategic land trading to the highest bidder.

The Right-to-Buy Fiasco

Fast-forward to 1980, when the Thatcher government passed the Right-to-Buy (RTB) legislation, a turning point in UK housing policy. RTB allowed council tenants to purchase their homes from the local authority at discounted prices leading to the sale of 2 million social housing units. However, the policy was not partnered with the financing to replace the lost social housing stock. Rather, since the 1980s and the Thatcher government, public expenditure on house building has dwindled. Additionally, this policy disincentivized social house building, as much of the purchase price goes to the treasury, instead of the local council unless they spend the money on affordable housing. But why would councils build homes if they do not receive the full value from the sale? As a result, since 1991, the UK has witnessed an average annual net loss of 24,000 social homes.

While the Conservative government aimed to increase homeownership and secure their voter base, the outcomes have been anything but straightforward. Research shows that over 40% of RTB homes are privately rented, often at exorbitant rents set by the new owners. It seems we might be dealing with a classic case of populism backfiring.

Potential Solutions

The unchanged planning system and preferential government policies have brought the UK’s housing supply to its knees. The simple fix would be to expand investment in affordable housing. However, for this to be possible and to incentivize the private sector, it would mean moving away from the discretionary planning system to improve the availability of land for housebuilding. A flexible rules-based planning system is one worthy alternative where development would be allowed unless specifically prohibited. For example, the portion of greenbelts that do not provide significant ecological value could be used for housebuilding. Regardless, this would require thorough land evaluation and substantial political will;  the latter being the bigger hurdle.

Another bold policy response is a land-value tax. This measure would target the landowners who hoard land, waiting for attractive offers from developers, or those with second and vacant homes. As advocates argue,

the necessity to pay the tax obliges landowners to develop vacant and under-used land properly or to make way for others who will.

While private landlords/landladies might pass the tax on through higher sale or rent prices, the increased number of properties added to the market would mitigate the drawbacks.

The UK's housing crisis is the result of decades-old planning laws and misguided policies that have restricted supply without impacting the rising demand, creating a perfect storm of unaffordability. Reforming the discretionary planning system and introducing innovative solutions like a land-value tax could pave the way for a more balanced housing market. But these changes require not just policy tweaks, but a shift in political will and public mindset. Until then, the pressure on the UK housing market will likely continue to build. It is time to rethink the rules and, perhaps, embrace a bit of boldness in policymaking.
