What is Change of Use?
In the world of property and planning, “change of use” refers to the process of altering how a building or land is used. The Use Class Order generally governs this in planning regulations, which categorise different types of building uses, such as residential, commercial, industrial, and more. Changing the use class of a property often requires prior approval or planning permission to ensure compliance with local regulations.

Understanding Prior Approval and Planning Permission
The change of use process in the UK typically involves two key steps. Firstly, there’s Prior Approval, which applies to certain changes under permitted development rights. These changes may not require full planning permission, but still need approval to assess impacts on transport, noise, contamination risk and flooding. Secondly, for changes not covered by permitted development rights, formal Planning Permission is required. This involves submitting a detailed application to the local authority, demonstrating how the proposed change complies with planning policies. It’s important to note that the specific requirements can vary depending on the nature of the change and local regulations.
