Building Safety (Wales) Bill Passed
A new era of accountability and structural safety for multi-occupied residential buildings in Wales.
On 10 March 2026, the Senedd officially passed the Building Safety (Wales) Bill. This legislation represents the most significant shift in property safety management in decades, expanding oversight beyond high-rises to include a wider range of mid-rise and residential buildings.
Key Regulatory Changes
New Duty Holders
The Bill introduces statutory roles with clear legal liabilities:
- Principal Accountable Person: Responsible for the structure and exterior of the building.
- Accountable Person: Responsible for fire safety and management of common parts.
- Competency Standards: Fire risk assessments must now be completed by a qualified "Competent Person."
Building Categorisation
The Welsh regime utilizes a three-tier system to determine the level of oversight required by the new Building Safety Authorities:
- Category 1: 18m+ or 7+ storeys (Highest oversight).
- Category 2: 11m–18m or 5–6 storeys.
- Category 3: Under 11m / 5 storeys (Specific focus on fire safety and HMOs).
