The CRU had 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 will begin from 1 April 2020. Electrical installations may be designed to the new standard from this date.
- After ten months (from 1 February 2021), all new electrical installations must be designed and certified to the new standard.
- After 28 months (from 1 August 2022), all electrical installations must be certified to the new standard.
- Installations may be designed to the old standard until 31 January 2021, provided they are certified to at least a pre-connection stage by 31 July 2022.
