How to Check if Your Project is Permitted Development

Tips & Watch-outs

  • The Planning Portal's interactive house guide (planningportal.co.uk) shows which works need permission for your type of property.
  • A Certificate of Lawful Development is not the same as planning permission, but it is equally valid proof of lawfulness.
  • If in doubt, ask your council's planning department. Most will give informal advice over the phone.
  • Always check PD rights before starting work — enforcement notices can be expensive.
