What are use classes and change of use?
Categorising land and buildings according to their type and purpose is known as Use Classes.
A 'Change of use' can be within the same Use Class or from one Use Class to another.
You will need planning permission for certain changes to the use of a property such as changing from a residential use to a business use. However, it is possible to change use between some classes without having to make an application for planning permission.
Depending on the specifics of any proposed change of use, including any building work associated with the proposal, an application for planning permission or prior approval may be required.
Common Questions
In many circumstances, rules known as ‘permitted development’ rights allow you to extend a house without needing to apply for planning permission, providing specific limitations and conditions are met. If you want to exceed these limits and conditions, then it is likely that an application for householder planning permission will be required.
You can find information about the limits and conditions, prior approval and the building regulations on the Planning Portal by using the links below.

If you live in a Conservation Area, a National Park, an Area of Outstanding Natural Beauty or the Broads, you will need to apply for planning permission before cladding the outside of your house with stone, artificial stone, pebble dash, render, timber, plastic or tiles.
Outside these areas, cladding may be carried out without having to first apply for planning permission provided the materials are of a similar appearance to those used in the construction of the house.
If the new materials will not have a similar appearance to those previously used you will be required to submit an application for planning permission.

Replacing existing render
Replacing existing render on the outside of your house with render of a similar appearance will not require planning permission as it is considered permitted development.
If you are changing the external appearance of the house or in a protected area such as a conservation area, then planning permission will be required. The external appearance of the house is likely to be changed when you are changing the type or colour of the render.
If the building is listed, then you will need listed building consent.
