Permitted development rights (PDRs) allow some building works and changes of use to be carried out without applying for planning permission.

These rights are different in National Parks, conservation areas, Areas of Outstanding Natural Beauty, and do not apply to listed buildings.

The General Permitted Development Order (GPDO) 2015 sets out what is covered. Common examples include:

• Householder works
  • Small rear and side extensions (within size limits).
  • Loft conversions and roof alterations (e.g. dormers or roof lights, within volume/height limits).
  • Porches up to a certain size.
  • Outbuildings such as sheds, garages, or greenhouses.
• Renewable energy
  • Installation of solar panels, heat pumps, and some other microgeneration equipment.
• Changes of use
  • Certain changes between commercial and residential use classes, subject to conditions and (in some cases) prior approval.

Other key points:

• Some developments require Prior Approval from the local authority before work can begin.
• Building Regulations may still apply even if planning permission is not required.
