A Decade-Low in Planning Applications: The Facts

Recent data from Landmark reveals that the number of planning applications submitted across the UK has fallen to its lowest point in over ten years. This decline has been steady since 2021 and is largely attributable to structural challenges within the planning system. While the data covers the entire UK, London landlords should be particularly alert given the city's complex planning environment and high development demand.

Why Does This Matter to London Landlords?

Planning permissions are critical for property developers and landlords looking to convert, refurbish, or expand their holdings. A reduction in planning applications signals potential bottlenecks and delays in approval processes. For landlords intending to add value through development or refurbishment, longer wait times for consents could impact project timelines and cash flow.

Practical Implications Across Landlord Profiles

  • Single-Unit Landlords: Those considering minor works or extensions should anticipate longer lead times. Even small-scale projects could face delays, affecting rental availability and income.
  • HMO Operators: Planning permissions for HMOs often require local authority scrutiny. Reduced planning capacity means applications might take longer, delaying potential new lettings or compliance upgrades.
  • Portfolio Landlords and Developers: Larger scale developments and refurbishments will likely encounter the most significant impacts. Strategic investment planning must factor in extended lead times and the potential for additional compliance hurdles.
  • Accidental Landlords: Those unfamiliar with planning considerations should seek advice before initiating works, as assumptions about quick permissions could lead to costly delays.

What Causes This Decline?

The structural issues cited include under-resourcing within planning departments, increased complexity in applications, and evolving local authority priorities. While specifics vary by borough, these factors collectively slow down the system, reducing yearly application volumes.

Mitigating Risks: Recommended Next Steps

  1. Monitor Local Planning Departments: Keep abreast of borough-specific guidance and any procedural changes. Many councils provide updates on expected processing times.
  2. Engage Early with Planning Consultants: Professional input can streamline applications and pre-empt likely issues, especially important in complex or contested cases.
  3. Review Development Timelines: Adjust project plans to factor in potential delays. Adding buffer periods can help manage cash flow and tenant communications.
  4. Communicate with Tenants and Clients: Manage expectations by informing them about possible timeline shifts, particularly if refurbishments affect occupancy or compliance.
  5. Consider Alternative Strategies: Where feasible, explore permitted development rights or other routes that might bypass full planning applications.

Strategic Planning for Property Teams

For landlords managing multiple properties or those working with in-house or external property teams, implementing a workflow that includes regular planning system reviews is advisable. This can help identify emerging trends or bottlenecks early and allow strategic decisions to be made proactively rather than reactively.
