Loft conversion

Planning permission is not usually required for a loft conversion. However, if you are altering a roof space that exceeds set limits and conditions, permission will be required.

It is best to check with your local authority or refer to our interactive house and mini guide to find out the rules on permitted development concerning lofts.

Building regulations approval will always be required to convert a loft into a liveable space.

Visit our common projects page to find out more about building regulations and permitted development for loft conversions¹.
