Certificates of lawfulness

A lawful development certificate is formal confirmation from the council that something is lawful. It gives you, your buyers and their solicitors certainty.

Two types of certificate

Proposed use or development. Confirms that work you plan to do is permitted development and doesn't need planning permission. Useful before building an extension or outbuilding, and very helpful when you sell.

Existing use or development. Confirms that something already built, or a use that's already happening, has become lawful, usually because it has existed for long enough without enforcement action. This needs clear evidence, such as dated photos, documents and statutory declarations.

How we help

  • For proposed works, we prepare drawings that show the project meets permitted development limits, and submit the application.
  • For existing works or uses, we review your evidence, tell you honestly whether it's strong enough, and prepare the application and supporting statement.

Questions

Frequently asked questions

Is a certificate compulsory?

Not for permitted development, but it gives certainty and is often requested by buyers' solicitors.

How long must something exist to become lawful?

It depends on the breach and when it began. The time limits in England changed in 2024, with ten years now applying in most cases, but there are transitional rules for older work. We can advise on your circumstances.
