The Building Safety Act is more than just another piece of regulation it completely reshapes how existing buildings are managed, maintained, and financed, especially higher-risk residential blocks. If you own, manage, design, or work on an existing building, you’re now operating in a very different landscape.
Below is a clear, practical look at 5 key impacts of the Building Safety Act on existing structures what’s changed, who is responsible, and what you actually need to do.
1. Higher-Risk Buildings Are in a Stricter “Safety Regime”
The Act introduces a dedicated regime for higher-risk buildings (HRBs), with tighter rules that apply throughout the life of the building, not just during construction.
In England, a higher-risk building during occupation is broadly defined as one that:
Is at least 18 metres high or has at least 7 storeys, and
Contains at least 2 residential units.
These buildings must now:
Be registered with the Building Safety Regulator (BSR) before occupation.
Meet ongoing safety obligations, with continuing oversight even after completion.
What this means for existing buildings?
If your building falls into the HRB category, you cannot ignore the Act as “for new builds only” – it applies to existing occupied buildings as well.
Owners and managers must understand whether their building is in scope, and if so, ensure it is registered and compliant with the HRB rules.
2. New “Accountable Person” & Dutyholder Roles
The Act creates new dutyholder roles to make accountability explicit.
For existing higher-risk buildings in occupation, the central figure is the Accountable Person (AP) – often the freeholder, head leaseholder, or management company responsible for repairing common parts.
There may also be a Principal Accountable Person (PAP) where more than one AP exists (for example, mixed-use developments).
Key duties for existing buildings
Accountable Persons must:
Assess and manage building safety risks (primarily fire and structural safety).
Prepare and maintain a safety case report showing how risks are controlled.
Engage with residents, share key information, and respond to safety concerns.
Cooperate with other dutyholders and the Building Safety Regulator.
For all building work (not just HRBs), a separate dutyholder regime also affects designers, contractors, and clients, requiring competence and clear allocation of responsibilities.
Practical impact
For existing structures, there’s no more “everyone and no one” being responsible.
Organisations must identify who the AP/PAP is, document this clearly, and ensure they understand their legal duties.
3. The “Golden Thread” and Stronger Information Requirements
One of the most significant changes is the emphasis on accurate, accessible data about the building – often called the “golden thread of information.”
For existing structures, this means:
You must build up and maintain a comprehensive record of:
Design and construction details (as far as reasonably possible).
Fire strategy, structural systems, and key safety measures.
Maintenance, inspections, and changes over time.
Key Building Information must be submitted to the BSR when registering higher-risk buildings.
Why this matters for existing buildings
Many older buildings have fragmented or incomplete records. Under the new regime, that is no longer acceptable.
Landlords and building owners need to fill gaps, commission surveys where necessary, and put in place a structured system for managing building information going forward.
4. Changes to Liability, Leases, and Cost Recovery
The Act doesn’t just focus on technical safety; it also reshapes liability and costs in relation to existing buildings.
Key aspects include:
Extended limitation periods for certain building defect claims, especially cladding and fire-safety related defects.
New routes to pursue parties responsible for building defects.
Amendments to the Landlord and Tenant Act 1985, imposing a duty on landlords (who are Accountable Persons) to manage Building Safety Risks – and enabling recovery of reasonable costs via service charges, subject to protections for leaseholders.
Impact on existing stock
Owners of existing buildings may face new obligations to remediate defects that previously might have been considered “historic” issues.
Service charge structures and lease wording need to be reviewed to align with the Building Safety Act and associated secondary legislation.
For anyone managing an existing tower or complex residential scheme, this means:
Greater financial exposure if safety is not proactively managed.
The need for clear communication with leaseholders about what is being done, why, and how costs are shared.
5. Ongoing Oversight, Enforcement & Cultural Change
Perhaps the most far-reaching impact is cultural: building safety is no longer a one-off exercise at completion; it’s a continuous obligation.
The Act establishes the Building Safety Regulator, within the Health and Safety Executive, to oversee building safety and enforce the new regime.
For existing buildings, this results in:
Mandatory registration and ongoing oversight for higher-risk buildings.
The potential for enforcement action, including improvement notices, stop notices, and even criminal sanctions where duties are breached.
A clear expectation that owners and managers will:
Embed safety into day-to-day operations.
Maintain competence and training across their teams.
Treat resident engagement as a core part of safety management, not an optional extra.
Bottom line for existing structures
The days of “build it and forget it” are over.
Existing buildings are now under a living regulatory framework, with safety risk management expected to be as routine as service charge budgeting or planned maintenance.
From Compliance Tick-Box to Proactive Safety Strategy
For owners, landlords, managing agents, and construction professionals, the Building Safety Act transforms existing buildings from static assets into actively managed safety systems.
To respond effectively, organisations should:
Determine if your building is a higher-risk building and ensure registration with the BSR.
Identify and empower the Accountable Person / Principal Accountable Person, with clear governance and reporting.
Create or improve your “golden thread” – accurate, up-to-date records of structure, fire strategy, and safety measures.
Review leases, contracts, and service charge mechanisms in light of the new cost and liability framework.
Embed a culture of continuous safety management, with regular reviews, resident engagement, and documented risk assessments.
Done well, compliance isn’t just about avoiding enforcement – it’s an opportunity to protect residents, preserve asset value, and demonstrate responsible stewardship of the built environment.
