The Building Safety (Wales) Act 2026 represents one of the biggest changes to residential building safety legislation in Wales in recent years.

Introduced following ongoing post-Grenfell building safety reforms, the Act creates a far more structured and accountable approach to managing fire and structural safety in residential buildings across Wales.

For managing agents, landlords, freeholders, RTM companies, and those responsible for residential blocks, the legislation introduces new legal duties, stronger compliance expectations, and increased accountability.

Which Buildings Does the Act Apply To?

The Act applies to “regulated buildings”, which are residential buildings containing two or more residential units. This includes many:

• Blocks of flats
• Mixed-use buildings with residential accommodation
• Certain HMOs
• Converted residential buildings

Buildings are now divided into three distinct categories:

The category of a building strictly determines the depth of legal duties required by law.

New “Accountable Person” Duties

One of the most significant changes introduced by the Act is the formal, legal concept of the:

These are the individuals or organisations legally responsible for managing building safety risks. In many cases, this framework includes:

• Freeholders
• Management companies
• RTM (Right to Manage) companies
• Managing agents acting directly on behalf of owners

The Principal Accountable Person will usually be the party responsible for the structure and exterior of the property.

Fire Risk Assessments Become More Strictly Regulated

The legislation places a clear legal duty on Principal Accountable Persons to ensure suitable and sufficient Fire Risk Assessments (FRAs) are completed for occupied regulated buildings.

Importantly, the Act strengthens competency requirements for Fire Risk Assessors. The Welsh Government now holds the powers to formally regulate competency standards, ensuring qualifications stand up to scrutiny regarding:

• Formal, industry-recognised qualifications
• Proven sector experience
• Third-party professional accreditation
• Active professional body memberships

Annual Fire Risk Assessment Reviews

The Act introduces mandatory review periods for Fire Risk Assessments. Current FRAs must now be reviewed at least every 12 months, and completely reassessed whenever significant changes occur, including:

• Refurbishment or ongoing construction works
• Changes in general building use
• Fire incidents, no matter how minor
• Structural alterations
• Disabled adaptations directly affecting designated escape routes

This shifting landscape moves residential fire safety away from a historical "one-off" tick-box exercise, reshaping it into a continuous safety management process.

Stronger Duties to Act on Fire Risks

The Act does not simply require buildings to "have an FRA" sitting on a shelf. Accountable Persons must actively manage risks by taking all reasonable steps to:

• Prevent fires from occurring in the first instance
• Drastically reduce the potential spread of fire
• Protect and maintain critical escape routes
• Improve general resident communication and safety
• Ensure firefighting infrastructure effectiveness

Structural Safety & Mandatory Requirements

For Category 1 and Category 2 buildings, the legislation goes well beyond fire safety alone. Duty holders must now formally assess and manage structural safety risks via:

• Routine structural inspections and monitoring defects
• Coordinating specialist structural engineering assessments

Furthermore, Category 1 and Category 2 buildings must be formally registered with the relevant Building Safety Authority. Failure to register an occupied building may result in criminal offences, including severe fines and potential imprisonment.

Additionally, Category 1 buildings must maintain a live “Safety Case Report” outlining all known fire and structural risks alongside implemented control measures, mirroring the higher-risk regime parameters found in England.

What This Means for Managing Agents

For block management operations, the 2026 regime demands:

• Audit-ready, robust compliance systems
• Strictly vetted, competency-checked contractor management
• Rigorous digital documentation and regular resident engagement

Portfolio workflows should immediately review:

1. Which specific categories your blocks fall into.
2. Who holds the legal title of Accountable Person.
3. Whether your current FRAs meet these updated, strict competency standards.
