What is Permitted Development?

Permitted developments are the minor alterations and extensions that can be carried out on a house without needing to apply for planning permission.

Do I Need to Apply for Planning Permission?

Legislation sets out the types of development that can be carried out to a house without the need to apply for planning permission. An easy to use interactive guide to the changes you can make to your house are contained on the Planning Portal website. You can explore an interactive house for advice on projects. This site also provides comprehensive information for householders and you can check a list of common building projects to see if the works you are considering will need planning permission.

You can also carry out some works within your garden, including outbuildings, without planning permission. An interactive outbuildings guide is also contained on the Planning Portal website.

Warning

You should always contact the Council to discuss your proposals before you carry out any works to your property. In some cases, the right to make alterations to a house has been removed, either when planning permission was originally granted or through an Article 4 direction. The right to carry out alterations if your house is a Listed Building or is located within a Conservation Area is also restricted.

You can contact us via email at planning@sthelens.gov.uk.

Can I Get the Council to Confirm I Don’t Need Planning Permission?

Yes, once you are satisfied that you may be able to carry out ‘permitted development’ and you would like the Council to confirm this in writing then you should apply for a ‘Certificate of Lawfulness of Proposed Development’. The forms and guidance can be downloaded from our Planning Application Forms page. The form should be accompanied by a 1:1250 location plan, a site plan and existing and proposed floor plan. There is a fee (please see fees pages). You can also apply online via the planning portal website.

If you have already carried out alterations to your house and you do not think planning permission was required at the time, then you can apply to the Council to for a ‘Certificate of Lawfulness of Existing Development’. As above, the forms and guidance can be downloaded from our Planning Application Forms page. The form should be accompanied by a 1:1250 location plan, a site plan and existing and proposed floor plan. There is a fee (please see fees pages). You can also apply online via the planning portal website.
