What to Expect

When you submit a householder planning application to Isles of Scilly, you have a very good chance of approval, with 9 out of 10 applications succeeding. However, you should be aware that only around half of applications are decided within the standard 8-week timeframe, so you may need to allow extra time for a decision. Despite this slower speed, the authority has never had a refusal overturned on appeal, which suggests their decisions are well founded and considered. Overall, this is a positive place to apply for planning permission as a homeowner.

Local Planning Considerations

The Isles of Scilly are a special landscape, and many parts are subject to conservation area protection, so you should check whether your property sits within one before applying. The islands also have unique environmental and heritage sensitivities that the council takes seriously when reviewing proposals. It's worth having a conversation with the planning team early on if you're unsure whether your plans align with local protection policies.

Tips for Homeowners

Get in touch with the planning officers at Isles of Scilly before you submit your application, as they are generally helpful and can point out any potential issues with your scheme early on. Because the islands are conservation focused, make sure your proposals respect the local character and heritage of your area, and consider how your development will sit within the existing community. Allow yourself plenty of time for the decision process, since applications here take longer than the 8-week standard, so submit well in advance if you have a deadline in mind. Finally, make sure your application is clear and complete from the start, as the high quality of decisions suggests the council values thorough and well-prepared submissions.

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.
