A faster, smarter, more affordable way to get planning permission anywhere in the UK.
A Lawful Development Certificate (LDC) is the only official way to prove that your proposed works fall under Permitted Development or that existing works are lawful. It protects you from enforcement action, future disputes, and issues when selling your property.
Planning World prepares and submits LDC applications with complete accuracy, ensuring your project is legally protected from day one.
When you need a Lawful Development Certificate
An LDC is essential when:
You believe your extension, loft conversion, outbuilding, or alterations fall under Permitted Development
You want written confirmation from the council before starting work
You’re selling your home and need proof that past works were lawful
You’ve inherited a property with undocumented alterations
You want to avoid planning risk, neighbour disputes, or enforcement notices
You’re in an Article 4 area where rights may be restricted
You’re in a conservation area and need clarity on what is allowed
Even if planning permission might not be required, an LDC gives you legal certainty.
