Lawful Development Certificate

What is a Lawful Development Certificate?

A Lawful Development Certificate (LDC) is an official document issued by a local planning authority in the UK that confirms a proposed or existing development is lawful and does not require planning permission. Property owners may apply for an LDC for two main reasons:

  1. Proposed Development: To confirm that planned changes or additions, like extensions, meet the criteria of permitted development rights and are lawful without requiring full planning permission.

  2. Existing Development: To confirm that a development that has already been carried out is lawful, either because it falls under permitted development or has become lawful due to the passage of time (usually four years for building work or ten years for change of use).

Why Obtain a Lawful Development Certificate?

An LDC isn’t a legal requirement, but it can be highly beneficial, especially for:

  • Certainty: Provides peace of mind to property owners, confirming that the development complies with planning laws.

  • Avoiding Enforcement: An LDC protects against enforcement action from the council for unauthorized development.

  • Selling Property: It can reassure potential buyers and their mortgage providers that all development work is lawful.

  • Insurance and Financing: Helps when securing home insurance or financing, as lenders and insurers often request proof of lawful development.

How to Apply for an LDC

An LDC application can be submitted to the local planning authority. The application should include detailed plans, specifications, and evidence supporting the lawfulness of the proposed or existing development. If the authority is satisfied that the development is indeed lawful, they will issue the certificate.

When to Apply for an LDC

It's advisable to apply for an LDC before starting work on a project you believe falls under permitted development, or if you suspect an existing alteration or use may require legal confirmation.

An LDC can also be beneficial in cases where property owners want to assert rights for developments that may have been carried out some time ago but where no planning permission was initially sought.
