Do you need permission?

In this section you will find planning and building regulations guidance for many common building work projects. You can:

  • Use our guides or the Common Projects links to find guidance on the building work you have in mind.
  • Check other important matters you should think about before starting work in the 'Your responsibilities' section.
  • When you have read and considered the guidance around whether or not you need planning permission or building control approval you can find out 'What to do next'.

From the May 2018, the Welsh Government will provide planning guidance to support their application service. You can access this guidance by visiting their website.

Your responsibilities

With all building work, the owner of the property (or land) in question is ultimately responsible for complying with the relevant planning rules and building regulations (regardless of the need to apply for planning permission and/or building regulations approval or not).

Therefore, failure to comply with the relevant rules will result in the owner being liable for any remedial action (which could go as far as demolition and/or restoration). The general advice is to always discuss your proposals with the relevant Local Planning Authority and Building Control Service before starting work.
