The Building Safety Regulator

The landscape of the UK built environment has undergone its most significant shift in a generation. As a result, the era of “learning on the job” regarding building safety is officially over.

At the same time, at the heart of this transformation is the Building Safety Regulator (BSR).

For developers, landlords, architects, and contractors, the BSR is no longer just a concept—it is the operational authority defining how we design, build, and manage high-rise structures. Ultimately, this guide outlines exactly what the BSR is, the critical updates you need to know, and, most importantly, how to navigate the rigorous “Gateway” system to ensure your projects remain compliant.

What is the Building Safety Regulator?

The Building Safety Regulator is an independent body established by the Building Safety Act 2022. Its primary mission is to oversee the safety and standards of all buildings in England, with a specific, rigorous focus on Higher-Risk Buildings (HRBs)—typically those over 18 metres or seven storeys with two or more residential units.

Originally, the BSR was formed within the Health and Safety Executive (HSE), but it evolved significantly this year. In fact, as of June 2025, the BSR transferred to become a dedicated executive agency within the Ministry of Housing, Communities and Local Government (MHCLG). This move, designed to streamline operations and accelerate decision-making for complex residential projects, marks a major shift in how building safety oversight is delivered.

The BSR has three core functions:

1. Regulating Higher-Risk Buildings:

   It is the sole Building Control Authority for HRBs. Private approved inspectors can no longer oversee these projects.

2. Raising Standards:

   It oversees the safety and performance of all buildings, ensuring the entire industry adheres to stricter regulations.

3. Improving Competence:

   It sets the bar for the competence of professionals working in the built environment, including building inspectors and control approvers.

🔴Critical Updates

Before looking at the operational requirements, it is vital to understand the most recent regulatory changes shaping the industry right now:

• New Charging Scheme: As of 1 April 2025, a revised charging scheme is in effect, including inflationary increases on hourly charges. The BSR operates on a cost-recovery model, meaning the industry directly funds the regulation it receives. Accurate budgeting for regulatory intervention is now essential.

• Fundamental Review of Regulations: The Deputy Prime Minister has instructed the BSR to review building regulations guidance to improve clarity. Expect consultations and potential changes to technical guidance over the next 12–18 months.

• Voluntary Occurrence Reporting (VOR): The BSR is actively encouraging VOR, which allows organisations to share near misses to help the industry learn. Adopting this demonstrates a proactive approach to safety that the regulator views positively.

• Free Training for Resident Directors: A new initiative from the BSR and LEASE offers free training for resident directors managing high-rise buildings. If your project hands over to an RMC, direct them to this resource to ensure they can fulfil the “Accountable Person” role legally.

The Three Gateways: “Stop/Go” Decision Points

The days of “build now, fix later” are gone. Instead, the BSR enforces a rigorous three-stage “Gateway” system. These stages serve as hard stops—construction cannot proceed to the next phase without explicit regulatory approval.

🛑Gateway 1: The Planning Stage

• When: Before planning permission is granted.

• Requirement: Developers must submit a Fire Statement demonstrating that fire safety has been integrated into the design process from the very start.

🛑Gateway 2: The Pre-Construction Stage

• When: Before any construction work begins.

• The Rule: This replaces the old “deposit of plans” method. Contractors can no longer start work on foundations while upper floors are being designed.

• The Timeline: You must allow for a 12-week determination period by the BSR.

• Change Control: If you change the design after Gateway 2 approval, you must submit a Change Control application. Major changes require construction to stop; notifiable changes must be reported.

🛑Gateway 3: The Completion Stage

• When: When construction is finished.

• The Rule: The BSR assesses if the “as-built” building matches the approved designs. A Completion Certificate is only issued if the building is safe. Crucially, the building cannot be legally occupied until this certificate is granted.

• The Timeline: Allow for an 8-week determination period after finishing the build.

• The Risk: The building cannot be legally occupied until a Completion Certificate is granted. Unauthorised deviations will result in refusal.

The “Golden Thread” of Information

One of the BSR’s biggest mandates is the creation of a “Golden Thread”—a digital, up-to-date record of all building safety information.

In the past, information was often lost between design, construction, and occupation. Today, the Golden Thread must be Digital, Interoperable, and Comprehensive. It must track every safety decision and material specification.

Note: If the Golden Thread is incomplete at Gateway 3, the BSR will not sign off on the building.

Dutyholders: Who is Responsible?

The regime places strict legal duties on specific individuals. You can no longer delegate safety responsibility entirely to a third party.

• The Client: Must make suitable arrangements for managing the project and verify that the team they hire is competent. If competence declarations are incomplete, the client—not the contractor—may be held liable.

• The Principal Designer (PD): Responsible for planning, managing, and monitoring the design phase to ensure compliance with building regulations.

• The Principal Contractor (PC): Responsible for the construction phase, ensuring site safety and build quality.

• The Accountable Person (AP): Once the building is occupied, the AP (usually the owner or management company) is legally responsible for assessing and managing safety risks (specifically fire and structural failure).

Enforcement

The regulator is an active enforcer, not a “tick-box” agency. Their powers include:

• Stop Notices: Ordering work to cease immediately if regulations are breached.

• Unlimited Fines & Prison Terms: Breaches can lead to unlimited fines and up to two years in prison for liable directors.

• Extended Liability: The limitation period for claiming compensation for defective work has been extended significantly (up to 30 years retrospectively in some cases).

How We Manage Compliance

At Focus Consulting, we don’t just advise on the new regime; we act as principal designers and contract administrators to guide Higher-Risk Buildings (HRBs) through the BSR gateways.

Compliance in 2025 requires a rigorous paper trail. For our HRB projects, we actively produce and manage the “Golden Thread” documentation required for Gateway 2 approval, including:

• Construction Control Plans: Detailing exactly how the project is planned, managed, and monitored to ensure building regulations are met.

• Change Control Plans: A digital log tracking every alteration to the agreed design—ensuring nothing is built without the necessary approval.

• Mandatory Occurrence Reporting: Systems to identify and report safety risks (structural or fire) directly to the Regulator.

• Competence Declarations: Formal confirmation that every contractor and designer on site is skilled, knowledgeable, and legally compliant.

If you own or manage a Higher-Risk Building, you cannot afford to guess. We have the templates, the systems, and the experience to ensure your project is safe, compliant, and ready for occupation.

If you would like support navigating the BSR process—whether at Gateway 1, 2, or 3—our team is here to help. We guide clients through compliance, documentation, and approval so projects progress smoothly and without costly delays.
