Everything You Need to Know About a Certificate of Lawfulness

What is a Certificate of Lawfulness?

A Certificate of Lawfulness confirms that a development or use is legally compliant, protecting you from future enforcement actions. This guide outlines the simple application steps, key documents you’ll need, and the crucial evidence required to ensure your application's success.

• Certificate of Lawful Existing Use or Development (CLEUD): Covers existing changes made without planning permission.
• Certificate of Lawful Proposed Use or Development (CLOPUD): Confirms the legality of a planned development before it begins.

The purpose and benefits of the Certificate of Lawfulness

The Certificate of Lawfulness provides several important advantages for property owners and developers:

• Formal confirmation of legality: This certificate provides official documentation that a use or development complies with planning law. It can bring peace of mind and avoid uncertainty about potential legal issues.
• Protection against enforcement action: If your development or use is challenged in the future, the certificate proves that the development was lawful, protecting you from enforcement actions by the local authority. This is especially useful if there are concerns about whether certain changes were made with the necessary permissions.
• Increased property marketability: Having a Certificate of Lawfulness can make it easier to sell your property, as potential buyers are reassured that there won’t be planning complications. It also helps when seeking a mortgage or refinancing, as lenders often require confirmation of the legal status of developments.
• Efficient alternative to retrospective planning permission: In cases where work has already been done without planning permission, the certificate offers a more streamlined route to confirming the legality of the development, avoiding the complexity and uncertainty of a full retrospective planning application.
• Clarity for future projects: For proposed developments, the Certificate of Lawfulness can confirm that the plans comply with current regulations before work begins, reducing the risk of costly delays or disputes later on.

The application process

You must submit a complete application to your local planning authority to apply for a Certificate of Lawfulness.

The application process involves several key steps:

• Application form: Complete the relevant form, typically available from your local council's website, where you provide details of the property, the type of certificate you're applying for (existing or proposed), and your contact information.
• Site location plan: This detailed map shows the property's location. To provide context, mark the property boundary in red and show the surrounding areas.
• Existing and proposed plans: These include floor plans and elevations of the property, showing the current state and any proposed changes. These documents help demonstrate the scope of the development or use.
• Supporting evidence: This is a crucial application element, as it strengthens your case. Evidence can include photographs, sworn statements, or documents like utility bills or council tax records showing the development's history.
• Application fee: You must pay a fee to submit your application, which varies depending on your local authority and the project scale. Be sure to check the current fee schedule on your council’s website.

Key points to understand on the application process

• Fact-based, not merit-based: Decisions are made on evidence and legal considerations rather than planning merits.
• Timeframes: Different time limits apply depending on the development. 4 years for residential use or building operations and 10 years for changes of use or breaches of planning conditions.
• Restrictions: You cannot apply if enforcement action is already in progress.

Evidence requirements

Strong, reliable evidence is critical to a successful application. This might include:

• Sworn affidavits: Legally sworn statements from witnesses attesting to the use or development of the property.
• Dated photographs: Photographs with visible dates visually record changes or long-term use.
• Utility bills, council tax records: Documents showing consistent utility or tax payments that prove continuous occupancy or usage.
• Tenancy agreements: Contracts that demonstrate rental history, supporting claims of lawful use.
• Electoral register entries: Records confirming the registered occupants of the property over time.

Considerations and Limitations of the Certificate of Lawfulness

A Certificate of Lawfulness is a valuable tool but comes with important considerations and limitations. Understanding these factors ensures a smooth application process and prevents potential complications.

• Burden of proof: The applicant is responsible for providing clear, sufficient evidence that the development or use complies with planning laws. With adequate proof, the application may be accepted.
• Limited scope: The certificate only confirms that the development complies with planning regulations, but it does not extend to other legal requirements like Building Regulations, fire safety, or environmental health.
• Validity: The certificate remains valid if the circumstances don’t materially change. If new developments occur or the use of the property changes, the certificate may no longer apply, and a new application might be required.
• Restrictions: A certificate cannot be granted if an enforcement notice has already been issued. Therefore, it is essential to act promptly, as any unauthorised development facing enforcement is not eligible for the certificate.
