What Happens After 8 Weeks?

By law, the local authority must provide a decision within 8 weeks. If they do not, you may request a decision through the "deemed approval" process, which automatically grants approval if the local authority fails to make a decision on time. However, this process is rare and may depend on the type of application.


How to Speed Up the Planning Process

To help avoid delays and ensure a smoother approval process:

  • Ensure all required documentation is included with your application.

  • Consult with your local planning authority before submission for advice on the application process.

  • Consider working with a planning consultant or architect to ensure your design aligns with local regulations and is more likely to be approved.

By being proactive and organized, you can help speed up the approval process.


Post-Approval Process

Once your planning permission is granted, you may still need to apply for building regulations approval. This process ensures that your project meets safety, structural, and energy efficiency standards. The building regulations approval typically takes 2-3 weeks to complete, depending on the complexity of the work.


Conclusion

The time it takes to get planning permission for your home extension or conversion can vary, but understanding the steps involved and being prepared can help streamline the process. Make sure your project complies with all local regulations, and be ready for potential delays. With the right approach, you can avoid setbacks and ensure your project gets approved in a timely manner.
