Planning & Building Regulations

Since the changes to planning law in October 2008, most loft conversions do not require planning permission. Planning permission would be required if your house falls within a conservation area or an area of outstanding natural beauty. However, your conversion does require building regulation approval, whether the conversion needs planning permission or not. We will carry out the application on your behalf.

All conversions must be inspected for building regulation approval either by the local authority building control or by an independent regulated inspector. After the building inspectors final visit & once the work has been passed a completion certificate will be issued.

Most lofts can be converted under permitted development. To be permitted development any additional roof space created must not exceed:

  • 40 cubic meters for terraced houses
  • 50 cubic meters for detached and semi-detached houses

Dormers can be built on the rear & the hipped side when the slope of any part of the roof doesn't face a highway. A gable up conversion (converting a hip to a gable) is also permitted in the same circumstances.
