What to Expect

When you submit a planning application to Cambridge, you can be fairly confident about getting approval. Around 94 out of every 100 householder applications are approved, which is a strong endorsement of how the authority handles residential proposals. You should expect a decision within 8 weeks in most cases, with the authority hitting this target around 84% of the time. The process is generally straightforward, and the team will help guide you through any issues that come up.

Local Planning Considerations

Cambridge has several conservation areas where additional restrictions may apply to alterations and extensions, so it is worth checking whether your property falls within one of these before you apply. The city also has areas of green belt around it, which can affect what development is possible on the edges of the built up area. It is always sensible to have a quick conversation with the planning team early on if you are unsure whether your location has any special designations.

Tips for Homeowners

Start by contacting the planning department informally to discuss your ideas before you submit a formal application. This gives you a chance to understand any local issues and can save you time and money if there are concerns the officer can flag early. Make sure your application is complete and well presented, because incomplete applications will delay your decision and test everyone's patience. Finally, bear in mind that while Cambridge has a good record of approving applications, the 20% of refused applications that go to appeal and succeed suggest that the authority can sometimes be overly cautious, so do not be afraid to seek professional advice if your application is refused and you think the decision was wrong.

About the performance rating: The score out of 100 is calculated from three factors: householder application approval rate (up to 40 points), the percentage of decisions made within the 8-week statutory target (up to 30 points), and the appeal overturn rate, where a lower rate means the authority makes sound decisions that hold up on appeal (up to 20 points). A further 10 points are available for data completeness. Source: MHCLG PS2 planning statistics and Planning Inspectorate appeal decisions, 2025 Q1-Q4.
