Due to the complexity of legislation, planning staff cannot give informal advice on the need for planning permission.
In some cases you do not need permission, this is called permitted development. You can use the interactive semi-detached house guide or explore the interactive terrace on the planning portal website to find out whether or not you should apply. You will need adobe flash player to use these guides.

Lawful development certificate
If you are not sure whether you need planning permission for a project, we recommend that you apply for a Lawful development certificate (LDC). This is different to planning permission and can be used to find out if a development requires planning permission. You can apply on-line for an LDC or download a form from planning portal. A Lawful Development Certificate is can be used to confirm that the use, operation or activity named in it is lawful for planning purposes.
It is a property or land owner’s responsibility to ensure that the relevant planning permission and building regulations are complied with, failure to do so can result in that person being liable for remedial action. You can find out more about your responsibilities on the planning portal website.
