How Long Does a Planning Application Usually Take?

Planning Application Timelines in South Wales

Introduction

One of the most common questions homeowners and developers ask is: “How long will my planning application take?” In South and West Wales, timelines can vary depending on the type of application, local council workload, and complexity of your project. Understanding typical decision periods helps you plan your construction schedule and avoid unnecessary delays.

Typical Planning Application Timelines

Different types of planning applications have specific statutory decision periods:

  • Prior Notification Applications (e.g., agricultural buildings, telecoms developments): 28 days

  • Householder Applications (extensions, loft conversions, small alterations): 8 weeks

  • Non-Material Amendment (NMA) Applications: 21 days

  • Certificate of Lawfulness of Proposed Development (CLOPUD): 8 weeks

  • Major Applications (large residential or commercial developments): 13 weeks

Note: These are standard decision periods, but delays can occur if councils request additional information, need to consult neighbours or other bodies, or if the application is particularly complex.

Factors That Can Affect Timelines

Several factors can influence how long your application takes:

  1. Application complexity – larger or unusual projects take longer to assess.

  2. Council workload – busy planning departments may extend processing times.

  3. Neighbour or public consultations – objections or consultations can add time.

  4. Environmental or heritage considerations – projects near protected areas or listed buildings often require additional review.

  5. Incomplete applications – missing or unclear documents can cause delays.

Tips to Speed Up Your Application

  1. Submit complete documents – site plans, floor plans, elevations, and supporting statements.

  2. Seek pre-application advice – local councils can advise on potential issues before submission.

  3. Work with a planning consultant – experts help ensure your application is compliant and clear.

  4. Respond promptly to council requests – providing additional information quickly keeps the process moving.

Conclusion

While planning application timelines vary depending on the type and complexity of your project, knowing the typical decision periods and preparing a thorough submission can save you time and reduce frustration. Early planning and professional guidance help ensure your application progresses smoothly.
