What are Permitted Development Rights…?

Put simply – these are policies which allow the homeowner or developer rights to extend a property, within certain specifications, relating to maximum depth and width, amongst other factors. There is no fee for Permitted Development, but we would always recommend the purchase of a Certificate of Lawful Development, which may be obtained from the local Planning Department. Not all developments can benefit from PD rights, such as those within a Conservation Area, Listed Buildings or properties of historical importance.

Here are some typical developments which may fall under Permitted Development:

  • Single Storey Extensions (to specified depths and width, depending on the existing property type)
  • Two Storey Extensions (rear of property only and with specific restrictive limitations prior to then requiring planning permission)
  • Loft Conversions (with specific restrictive limitations prior to then requiring planning permission)
  • Outbuildings & Garages
  • Roof Windows
  • Dormer Windows
  • Solar Panels

The Housing Secretary, James Brokenshire, confirmed that new PD rights will include the right to extend upwards on some commercial and residential buildings. This has been met with some opposition within the industry, with concerns over amenity and also practical issues such as fire safety regulations.

Permitted Development rights allowing longer single-storey rear extensions to existing homes, introduced as a temporary measure in 2013, were due to expire at the end of May 2019. These are going to be made permanent and will be subject to a ‘proportionate’ planning fee. In contrast, rights to convert buildings used for storage to residential use, due to end on 10 June 2019, will not be extended.
