Lawful Development Certificate - Existing Use or Development

An application for a Lawful Development Certificate (Existing) form should be used to establish whether an existing use of land, or some operational development, or some activity in breach of a planning condition, is lawful even though it did not have planning permission.

Examples when an application for a Lawful Development Certificate (Existing) should be made include:

  • when planning enforcement action is taken by the local planning authority and the owner believes it is immune from action because the time limit for taking enforcement action has passed;
  • when an owner discovers, in the course of a sale of the land, that planning permission has never been granted, and needs to show a prospective purchaser that no enforcement action can be taken by the local planning authority.

What is required?

This must be an up-to-date Ordnance Survey-based location plan at an appropriate scale, usually 1:1250 or 1:2500. In the case of large sites other scales may be appropriate.

The plan must show:

  • At least two named roads and all surrounding buildings or land (unless this would require a plan greater than a scale of 1:2500)
  • The application site (the whole planning unit)
  • A north point
  • The scale clearly identified

The plan used should:

  • Show OS Crown copyright
  • Not to be copied from existing OS mapping, if using hand drawn maps such as standard streets
  • Show the correct licence number if you wish to print or copy maps for applications

The application site boundary must be edged clearly with a red line. It should include all land necessary to carry out the proposed development - for example, land required for access to the site from a public highway, visibility splays, landscape, car parking and open areas around the building. A blue line should be drawn around any other land owned by the applicant, close to or adjoining the application site.
