The UK's planning policy landscape has recently undergone significant changes, opening up new avenues for development, particularly in the newly defined "grey belt" areas. For developers, this presents a unique opportunity to capitalise on land that was previously off-limits. In this blog, we will delve into the specific changes to planning policy, explain what the grey belt is, and show how the Nimbus platform can be your key to identifying and leveraging these opportunities.

What is the grey belt?

The grey belt is a new concept that has emerged alongside the UK government's recent updates to planning policies. Traditionally, the "green belt" has been an area where development is heavily restricted to preserve open land and prevent urban sprawl. However, the pressing need to meet housing demands has led to a re-evaluation of some of these areas.

Grey belt areas are specific parts of the green belt that, under new planning policies, may now be considered suitable for development. These areas typically include:

• Previously developed land (PDL): Sites that have been previously built upon, which might now be available for redevelopment even if structures have been demolished.
• Agricultural and forestry buildings: Existing buildings within the green belt that could be repurposed or redeveloped under new guidelines.
• Brownfield sites: Former industrial or commercial sites that are derelict and could be revitalised for new uses.
• Residential gardens and parks: Larger gardens or recreational areas within the green belt that may support limited development without severely impacting the openness of the green belt.

Detailed changes to planning policy

The UK government's latest planning policy updates introduce several critical changes aimed at making it easier to develop within grey belt areas. Here are the key updates:

1. Reinstatement of mandatory housing targets

   • The government has reinstated mandatory housing targets that local authorities must meet. If an area fails to meet at least 75% of its housing targets over the past three years, developers may find it easier to gain approval for development, even within grey belt areas.
   • Impact: This change increases the pressure on local authorities to approve new developments, making grey belt land more accessible.

2. Relaxation of green belt restrictions

   • While the green belt's core purpose remains, the government is now more open to development in certain parts of the green belt (i.e., the grey belt), especially if it can be demonstrated that the development aligns with sustainability goals and does not significantly harm the area's character or openness.
   • Impact: Developers now have a stronger case for proposing developments in these newly identified grey belt areas, particularly in regions with unmet housing needs.

3. Emphasis on sustainability and biodiversity

   • The new policies place significant weight on developments that contribute to net-zero targets or enhance local biodiversity. Projects that incorporate green technologies or improve environmental conditions are more likely to receive favourable consideration.
   • Impact: This creates a strong incentive for developers to integrate sustainable practices into their designs, potentially increasing the viability of projects within the grey belt.

4. Support for increased density

   • The government is encouraging higher-density developments in appropriate locations to maximise land use efficiency. This includes supporting upward extensions and higher densities in both urban and suburban areas. 
   • Impact: This policy shift opens up opportunities to propose denser developments within grey belt areas, particularly where existing infrastructure can support it.

5. No immediate changes to permitted development rights

   • The government has not introduced significant changes to permitted development rights (PDR) under the new policies, but developers should remain informed as further updates could impact grey belt development strategies. 
   • Impact: Developers can continue to utilise existing PDRs to maximise opportunities in grey belt areas.
