A conservatory built with a floor area of no more than 30m2 is normally exempt from the Building Regulations, provided that:

  • The conservatory is separated from the building by external quality doors, windows and walls;

  • Any glazing and fixed electrical installation complies with the applicable requirements of the Building Regulations (i.e. Part K - ‘Protection from falling,collision and impact’ and Part P - ‘Electrical Safety’ for England only) (Part N - ‘Glazing’ and Part P - ‘Electrical Safety’ relevant to Wales).

Any new structural opening or the increased width of the original opening between the conservatory and the existing house will require approval.
