Requirements and regulations

Planning regulations

New planning regulations came into effect from 1 October 2008 that loft conversions can and are in most cases be constructed and carried out under your ‘permitted development‘ rights, however these regulations were updated in January 2013, therefore if your loft conversion falls within certain building regulations limits and considerations you still will not need to go through planning, but all loft conversions have to go through stringent building control regulations.

These are the main reasons you would not normally need to obtain planning permission providing that:

  • A volume allowance of 40 cubic meters additional roof space for terraced houses
  • A volume allowance of 50 cubic meters additional roof space for semi-detached and detached houses
  • The property is a domestic dwelling and is not a marionette or flat
  • The existing roof line to your property is not raised
  • Hip to Gable side-facing windows must be obscure-glazed
  • The building is not listed as special architectural or have historic interest
  • The building is not located in a conservation area
  • The proposed extension or dormer window is not raised above the highest part of the roof or slope, and does not face a public highway

However here is what has to be taken into consideration regarding planning.


Thermal insulation is an absolute must and is to be used in all new walls and ceilings, this insulation must comply with building regulations ‘Approved Document E‘ meeting the minimum energy efficiency values. When installing loft insulation at the eaves, extra care must be taken to ensure that they are not blocked to ensure the possibility of interstitial condensation is kept to the bare minimum.


Approved Document Part P‘ of the Building Regulations requires that the installation of all new and any repair/addition electrics must conform to BS 7671: 2008 17th Edition IEE Wiring Regulations. A ‘Residual Current Device’ must be installed to protect all electrical wiring carried out within a loft conversion.
