Do I need building regulations?

Works requiring a Building Regulations Application

The following building works require a Building Regulations application to be made. This is not a comprehensive list, so please contact us if you are unsure.

  • The erection of a new building or the extension of an existing building. (e.g. a kitchen extension or loft conversion)
  • Structural alterations to an existing building. (e.g. underpinning, removal or alteration of load bearing walls, removal of a chimney)
  • Alterations which may affect the means of escape in case of fire. (e.g. changes of layout, changing the use of rooms, alterations to fire doors)
  • Changing the use of an existing building. (e.g. converting a house to flats, or a shop to an office)
  • The extension or alteration of certain services and fittings. (e.g. installing new drainage, replacing windows if the fitter is not FENSA registered)
  • Since the 1st January 2005, most electrical work is also included. More information on Part P.
  • Since April 2006 renovating or replacing a wall, floor or roof has also fallen under the building regulations. (e.g. replacing a roof, re-tiling a roof, replacing a floor, re-plastering substantial areas)
  • Changes to a buildings energy status now also require building regulations. This might happen where a previously unheated space is being heated or where air conditioning is being installed.
