There is generally no mandatory requirement to retrofit buildings in relation to balustrades to meet current standards (unless a building order/notice has been issued). Our reports will most often make a recommendation to upgrade balustrades as a measure to improve safety. However, in some cases balustrades can deviate from current standards to a significantly and consequently large extent and present (irrespective if compliant or not) fall hazards, in which case it is highly recommended that they be modified/upgraded or replaced to meet current standards and eliminate or reduce hazards.
