Expert help from trusted planning consultants

Have you carried out works or changed the use of a property without planning permission, or are you proposing development and need confirmation that permission is not required?

At Fytche-Taylor Planning, we help property owners, developers and businesses secure Lawful Development Certificates (LDCs), providing certainty, protecting your investment and reducing the risk of future enforcement action.

What is a Lawful Development Certificate?

A Lawful Development Certificate (LDC) is a formal confirmation from your Local Planning Authority that an existing or proposed use, operation, or building works are lawful under planning law.

There are two main types of LDC:

  1. Existing Use or Development (Section 191) – for activities or works already carried out. Once granted, the use or development is protected from enforcement action.

  2. Proposed Use or Development (Section 192) – for new works or changes you plan to carry out, giving certainty that planning permission is not required.


Why it matters:
Obtaining an LDC provides legal certainty, safeguards property values, and reduces risk when selling, leasing, or developing land.

When Might You Need an LDC? Typical scenarios include:

  • A barn or property converted years ago without planning permission.

  • Change of use implemented long ago where formal confirmation is required.

  • Proposed extensions, works, or development where you want to verify permitted development rights.

  • Property transactions where buyers or lenders request proof of lawful use.

Frequently asked questions

Q: Do I have to get an LDC?
A: No — but it gives you a formal legal document, which can be very valuable especially when buying/selling land or defending past works.
Q: What if I don’t have 10 years’ evidence?
A: That may limit your ability to demonstrate immunity from enforcement; we’ll advise on all options.
Q: Will getting an LDC remove the need for Building Regulations / other consents?
A: No — an LDC deals only with planning law. You must still satisfy Building Regulations, listed building consent, etc. National guidance emphasises this.
