When objecting to a planning application, there are certain things that you should always try and make sure you do:
1. Write the application reference number and name/address of the scheme at the top of your letter. This will make sure that there is no confusion as to which application you are objecting. This is less of an issue if you choose to make your representations by way of the online system that most local authorities use because you have to navigate your way to the application in question before you can submit your objections.
