What to Expect

You can be confident that your householder application has a good chance of success, with a 90% approval rate among similar applications in this area. However, you should be prepared for the decision to take a little longer than the standard 8 weeks, as only 55% of applications are decided within this timeframe. The council will work through your application carefully, and when decisions are made, they tend to be final, as the appeal overturn rate is notably low. Overall, whilst the process may take slightly longer, the likelihood of approval is genuinely encouraging.

Local Planning Considerations

The Isles of Scilly are designated as an Area of Outstanding Natural Beauty, which means your plans will need to respect and protect the special landscape and character of the islands. Many buildings and areas have additional protection through conservation designations, so it is important to check whether your property or proposed development falls within these areas before you apply. Any proposal that could affect the islands' unique environment, wildlife, or heritage will receive careful scrutiny from the council.

Tips for Homeowners

Start by having a clear conversation with the planning team at the council before you submit anything formal, as they can give you valuable guidance specific to your location and the nature of your proposal. Make sure you provide plenty of detail about how your project fits with the island landscape and character, as this will be important to the council's decision making. Since decisions can take a little longer here, build extra time into your plans if you have a deadline, and consider submitting your application well in advance of when you hope to start work. Finally, if your property is in or near a conservation area, invest time in understanding those protections and how they affect what you can and cannot do.

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.
