The CRU had originally decided on a transition period of 24 months to enforce compliance with the new standard. However, transition deadline dates have been delayed by 4 months due to the Covid-19 pandemic. Therefore, the total transition timeline will be extended to 28 months. The following applies to all restricted and controlled electrical works in either commercial or domestic properties:
The transition period began on 1st April 2020. Electrical installations may be designed to the new standard from that date.
After ten months (from 1st February 2021), all new electrical installations must be designed and certified to the new standard.
After 28 months (from 1st August 2022), all electrical installations must be certified to the new standard.
Installations may be designed to the old standard until 31st January 2021, provided they are certified to at least a
pre-connection stage by 31st July 2022.
