Question 1

What is a Certificate of Lawfulness?

Accepted Answer

A Certificate of Lawfulness (formally a Lawful Development Certificate, or LDC) is a legal document issued by the local planning authority confirming that a particular development or use of land is lawful. There are two types: a Certificate of Lawfulness for a Proposed Use or Development (CLOPUD) - confirming that proposed works fall within permitted development rights and do not require planning permission; and a Certificate of Lawful Existing Use or Development (CLEUD) - confirming that existing works or a use of land have been in place long enough that the local authority's right to take enforcement action has expired (4 years for operational development such as extensions; 10 years for a change of use). The certificate is legally binding and runs with the land - it remains valid regardless of who owns the property.

Question 2

Do I need a Certificate of Lawfulness?

Accepted Answer

A Certificate of Lawfulness is not legally required - if works genuinely fall within permitted development, they are lawful whether or not a certificate is obtained. However, obtaining a certificate is strongly advisable in several situations: when selling the property (buyers' solicitors routinely request evidence that works carried out without planning permission were lawful - a certificate provides that evidence and prevents the sale stalling); when mortgaging the property (lenders may require confirmation that works are lawful); when there is any doubt about whether the works fall within permitted development limits (the certificate provides certainty); and when the permitted development rights could be disputed (for example, if the property is in an area where similar permitted development has previously been refused). The fee is modest and the process is quicker than a full planning application.

Question 3

How long does a Certificate of Lawfulness take?

Accepted Answer

The statutory determination period for a Certificate of Lawfulness application is 8 weeks from validation - the same as a householder planning application. In practice, many authorities determine straightforward CLOPUD applications (for proposed permitted development works) within this period, since the assessment is legal rather than discretionary - the authority is simply checking whether the works comply with the General Permitted Development Order, not exercising planning judgment. CLEUD applications (for existing works or uses) can take longer if the authority needs to investigate when the development was completed or the use established. The authority cannot refuse a Certificate of Lawfulness if the development genuinely falls within permitted development - the decision is a legal question, not a policy one.

Question 4

What is the difference between a Certificate of Lawfulness and planning permission?

Accepted Answer

Planning permission and a Certificate of Lawfulness are fundamentally different legal instruments. Planning permission is a discretionary consent granted by the local planning authority under planning policy - it can be refused if the development does not comply with planning policies. A Certificate of Lawfulness is a legal declaration that the development is already lawful - the authority has no discretion to refuse it if the development genuinely falls within permitted development rights or if the enforcement time limit has expired. Planning permission may be subject to conditions; a Certificate of Lawfulness cannot be subject to conditions (it is a declaration of existing law, not a new consent). For works that fall within permitted development, a Certificate of Lawfulness is the correct and appropriate document - not a planning permission. Obtaining planning permission for permitted development works, while possible, is unnecessary and provides no additional benefit over an LDC.
