Building Safety Act: What Freeholders Must Do by 2026

Registration deadlines, safety case reports, the golden thread of information and accountable person duties for owners of higher-risk residential buildings.

Regulatory UpdateApril 2026Building Safety
Overview

The new regulatory landscape

The Building Safety Act 2022 represents the most significant reform of building safety regulation in a generation. For freeholders and building owners of higher-risk residential buildings, the Act introduces mandatory registration, ongoing safety management obligations, and the requirement to maintain a golden thread of building information. Non-compliance carries serious penalties including criminal prosecution.

Registration with the Building Safety Regulator

All existing higher-risk buildings (residential buildings at least 18 metres or 7 storeys with two or more residential units) must be registered with the Building Safety Regulator (BSR), which sits within the Health and Safety Executive. Registration requires providing key building information including the address, height, number of storeys, number of residential units, and details of structural and fire safety features. The principal accountable person is responsible for registration and for keeping the information up to date.

The safety case report

The accountable person must prepare a safety case report for the building. This is a structured document that identifies the building safety risks (principally fire spread and structural failure), assesses the likelihood and consequences of those risks materialising, and sets out the measures in place to manage and mitigate them. The safety case report must be submitted to the BSR as part of the application for a building assessment certificate.

The golden thread

The golden thread requires the accountable person to create and maintain accurate, accessible, up-to-date digital records of all building safety information. This includes the original design and construction information, records of all subsequent building works, fire risk assessments, fire compartmentation surveys, maintenance records, and the safety case report itself. The information must be stored digitally, kept up to date, and made available to the BSR on request.

Resident engagement

The Act requires accountable persons to establish and maintain a resident engagement strategy. This includes providing residents with information about fire safety measures, reporting mechanisms for safety concerns, and a complaints procedure. Residents have a right to request building safety information and the accountable person must respond within a specified timeframe.

Compliance Steps

Key actions for freeholders

Register the building

Confirm whether your building meets the higher-risk definition and register it with the BSR. Provide accurate information about the building's height, storeys, units and safety features.

Identify the accountable person

Determine who holds the legal estate in possession and therefore assumes the role of accountable person. In complex ownership structures, identify the principal accountable person.

Prepare the safety case

Commission fire risk assessments, structural appraisals and fire compartmentation surveys to inform the safety case report. Identify risks and document mitigation measures.

Establish the golden thread

Collate all existing building safety information into a digital format. Implement systems to ensure ongoing maintenance and building works are recorded and the information kept current.
