Do I need a Lawful Development Certificate?

A Lawful Development Certificate (LDC) is a legal document confirming the lawfulness of past, present, or future development. You might require an LDC if you've been using a property for an extended period without planning permission, or if you need to establish the current or proposed use of a building/land as lawful.

There are two types of certificates that can be applied for:

  • Certificates of Lawful Existing Use or Development (CLUED or CLEUD)

  • Certificates of Lawful Proposed Use or Development (CLOPUD)

These applications do not involve consideration of planning merits. Instead, they focus solely on evidence, facts, and legal considerations.

The certificate confirms that the existing use, operation, or activity specified within it is lawful and therefore cannot be subject to enforcement action. This can be particularly valuable when selling the property or securing a mortgage, providing assurance to potential buyers or lenders regarding the legality of the use.

How do I obtain a Lawful Development Certificate?

If you wish to obtain a LDC an application must be submitted to the relevant local authority for approval.

Obtaining a LDC requires substantial evidence, which can include sworn affidavits from owners and neighbours, dated photos or satellite images, rental agreements, council tax records, utility bills, invoices for services, leases etc. The more evidence provided, the stronger the case for obtaining the certificate.

Refusal of a LDC doesn't necessarily mean that the proposed development or use is not lawful; rather, it indicates that planning permission is required, assuming the decision is correct. If you disagree with the refusal, you have the option to appeal the decision, just as you would with a planning permission refusal.

Any current use of the building must be visible and in the open to avoid concealment.

A LDC cannot be utilised in situations where breaches of listed building or conservation area controls are alleged.

Steps to planning your extension:

Initial Consultation: Discuss your ideas with a proffesional to understand feasibility, costs, and design options.

Design and Planning: Your proffesional will advise you as to whether your extension falls under permitted development or requires planning permission, you can then work together to develop detailed plans to submit to the council.

Building Regulations Approval: Following gaining consents from the council, it is advisable to have some detailed construction drawings produced, demonstrating compliance with Parts A-S of the UK building regulations. These will then be submitted to building control.

Party Wall Agreement: If necessary, obtain agreements from neighbour’s affected by the extension.

Construction: Following building control approval, hire a reputable builder and commence construction, ensuring all work is inspected and certified as per building regulations.

Completion: Once construction is finished, obtain a completion certificate from building control, confirming that the extension meets all regulatory requirements.
