What to Expect

When you submit a planning application to Hounslow, you can expect a fair chance of approval with a 72% approval rate for householder applications. However, you should be prepared for a longer wait than the standard 8 weeks, as only 57% of applications are decided within this timeframe. Some applications may take considerably longer, so patience and forward planning are important. The good news is that if your application is refused, you have a reasonable chance of success on appeal, with 47% of refused applications overturned.

Local Planning Considerations

Hounslow includes several conservation areas where stricter rules apply to external changes and alterations, so check whether your property falls within one before applying. The borough also has areas designated as green belt and contains various heritage assets, so proximity to these features may influence what you can build or alter. It is worth researching your specific location early on, as these designations can affect what is and is not allowed.

Tips for Homeowners

Start by getting clear information about whether your property is in a conservation area, as this will significantly affect what you can do. Make sure your application is as thorough and well presented as possible, because good quality submissions help the council make faster decisions and reduce the chance of refusal. Consider using an agent or architect if your project is complex, as professional help can streamline the process and improve your chances of success. Finally, do not be discouraged if the initial decision takes longer than 8 weeks, as this is common at Hounslow, but do chase the council for updates if you have not heard anything for several months.

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.
