Must comply with Schedule 1 of the General Regulation.

The installation doesn't need BA if:

  • it is for a class 1 or class 10a building only
  • it involves an air-conditioning unit and isn't the main source of ventilation for the room or building and
  • it follows all other general rules.

If you're building an internal fireplace, you must get BA.
