If your application is refused a refusal notice will be issued by the council, which should list the relevant policies it conflicts with and the reasons why.
If your application is refused, you can submit a modified application to try and overcome the reasons for refusal. Alternatively, you can appeal, within 6 months, to the Planning Inspectorate. If you wish you can pursue both options at the same time. If you have been granted planning permission subject to conditions and you object to one or more of these conditions, you can also apply to vary or remove them or appeal against them.
