Lawful development certificate

Before carrying out any permitted development works we recommend you apply for a lawful development certificate (LDC). This is not the same as planning permission but is proof that your building work is lawful.

Even if you're sure your project is a permitted development, it provides formal confirmation for your peace of mind. If you should later want to sell your property, an LDC may be helpful to answer queries raised by potential buyers or their legal representatives.

How to apply

You can apply using the Planning Portal's secure online application service. 

To apply you need:

• a site location plan
• an accurate scale plans of the existing and proposed property
• to pay the application fee of £621 including VAT
