New Regulations that strengthen the building control system for higher-risk buildings in Wales, alongside broader updates to existing building regulations, took effect on 1 July 2026.

 

The key updates include:

  • Clear responsibilities and competence standards for those involved in building work (duty-holder roles for Clients, Designers and Contractors).
  • Compliance and Stop Notices that give new enforcement powers for local authority building control.
  • The introduction of Gateways for higher-risk building projects that create hard-stops where building work cannot start without approval.
  • Golden Thread of building information for higher-risk buildings, ensuring vital safety information from the design and construction phase is maintained and readily accessible.
  • Mandatory reporting of any significant safety occurrences during work on higher-risk buildings.
  • Building control approval will now lapse automatically if work does not commence within three years

These changes are part of the Senedd’s ongoing commitment to improving building safety for everyone across Wales. ​​​​​​​
