What to Expect
When you submit a householder planning application to Hillingdon, you have a good chance of approval, with 88 percent of applications being granted. You should be prepared for the decision to take a bit longer than the standard 8 week target, as only 61 percent of applications are decided within this timeframe. Most applicants can expect a decision within 8 to 13 weeks, though some applications may take longer depending on complexity. If your application is refused, you have a reasonable prospect of success if you choose to appeal, with 43 percent of appeals overturning the original decision.
Local Planning Considerations
Hillingdon contains some important conservation areas and green belt land, so check whether your property is in one of these designated areas before you apply, as this will affect what you can build. The borough also has various Article 4 directions in place in certain locations, which remove certain permitted development rights, so it's worth verifying your specific local area restrictions on the council's website.
Tips for Homeowners
Start by checking the council's online mapping system to understand any designations affecting your property, such as conservation status or green belt, as these will shape what the planning officers can approve. Take time to prepare a clear and detailed application with good quality drawings and photographs, as the council will need to properly understand your proposals, and clarity can help speed up the decision process. If your application is refused, don't lose heart, as nearly half of all appeals in this borough succeed, so seeking professional advice on an appeal may well be worthwhile. Consider getting pre application advice from the council before you submit, as this can help you understand any concerns early on and improve your chances of a smooth approval.
