Every decision will be made after looking at:
Your views are only one part of what is considered and may not be more important than other factors. In law the decision must be made in line with the development plan unless it is proved otherwise. Also, Government advice is that development plans should generally be approved unless there are significant planning objections.
Once a decision is made only the person making the application has the right to appeal - either against a refusal or any condition imposed. Neighbours and other interested people cannot appeal against the decision.
If an appeal is made then an inspector chosen by the Planning Inspectorate will look at the matter. If you commented on the original planning application then you will be told of the appeal and be invited to give your views to the Planning Inspectorate. Any comments you made on the original application will have already been forwarded to the Inspector. More information about the appeal process is available from the Planning Advisory Desk.
If plans by a householder are refused, any representations made about the application will be sent to the Secretary of State, but there will be no further chance to comment at appeal stage. You will be told of this at the time the appeal is made and you will be able to withdraw the comments if you wish.
