What is a Certificate of Lawfulness Application?

A certificate of lawfulness application is a formal request submitted to your local planning authority to establish that a particular use or development is lawful. There are two main types:

1. Certificate of Lawfulness of Existing Use or Development (CLEUD)

   This proves that an existing use or building works have been in place for a certain period (usually 4 or 10 years) without enforcement action, making them lawful.

   
   

2. Certificate of Lawfulness of Proposed Use or Development (CLOPUD)

   This confirms that proposed works or uses would be lawful if carried out, based on planning rules.

   
   

The application requires detailed evidence such as:

• Historical planning records

• Photographs showing the use or development over time

• Statutory declarations from neighbours or professionals

• Site plans and architectural drawings

  
  

AGA Associates specialises in preparing and submitting these applications, ensuring all evidence meets the strict criteria set by London borough councils.

Why You Should Consider a Certificate of Lawfulness Application

Applying for a certificate of lawfulness offers several benefits:

• Legal Certainty: It confirms your rights and protects you from enforcement action.

• Property Value: It reassures buyers and investors, potentially increasing your property’s market value.

• Planning Clarity: It clarifies what you can legally do with your property, avoiding costly mistakes.

• Smooth Transactions: It simplifies property sales or refinancing by providing clear legal status.

  
  

For example, if you have carried out a loft conversion without planning permission but it has been in place for over 4 years, a certificate of lawfulness application can legalise the work retrospectively. This is invaluable for landlords or homeowners planning to sell or rent out the property.
