The Building Safety Regulator (BSR) has rolled out fresh guidance on building assessment certificates and updated its charging scheme, while two product safety notices flag risks with fire alarm systems and fire doorsets. For our team at Mixit, these regulatory shifts directly affect the projects we supply concrete to across London, Essex and Herts. Here is what our clients and partners need to know right now.

Key Takeaways

• The BSR has published a clear process for principal accountable persons to apply for a building assessment certificate, creating new compliance checkpoints on higher-risk buildings.
• Detailed preparation guidance now spells out exactly what documentation must accompany each application, reducing rejection risk for developers and contractors.
• The BSR’s updated charging scheme sets out transparent fees for building control, inspection and registration functions.
• A product recall on the Bull and Cygnus Fire Alarm Detection System (FADS) demands immediate attention from any site using this equipment.
• A separate product safety report on Metador Defender Fire Doorsets raises questions about fire compartmentation on active construction projects.

Building Assessment Certificates Now Have a Defined Application Route

Principal accountable persons for higher-risk buildings in England can now use a formal digital service to apply for a building assessment certificate from the Building Safety Regulator. This matters to us because many of the residential and mixed-use projects we supply concrete to fall within the higher-risk building category — typically structures over 18 metres or seven storeys with at least two residential units.

Our clients should treat this as a scheduling consideration. Certificate applications can trigger inspections, and inspections can delay handovers. We advise project managers to factor BSR timelines into their pour schedules and structural completion milestones.

Preparation Guidance Cuts Guesswork for Applicants

The BSR has also published specific instructions on preparing a building assessment certificate application. The guidance details the exact information principal accountable persons must submit, covering structural safety data, fire risk documentation and resident engagement records.

For our part, we ensure every concrete delivery is accompanied by full batch documentation — mix design, strength class, consistence and conformity certificates. This traceability is not optional. It feeds directly into the evidence packs our clients need when facing BSR scrutiny. We recommend contractors keep our delivery tickets and test certificates filed alongside their structural engineer sign-offs from day one.

BSR Charging Scheme Brings Fee Transparency

The regulator has published its full charging scheme for building control, inspection, registration and other functions. Fees are calculated based on the complexity and scale of the building. This is useful intelligence for quantity surveyors and developers pricing up projects in our supply area.

We see this as a positive step. Transparent fees mean fewer budget surprises mid-project. Our team already works closely with clients on cost planning for concrete supply; knowing the regulatory cost baseline helps everyone build more accurate programmes.

Fire Alarm Recall Demands Immediate Site Action

The Office for Product Safety and Standards has issued a product recall for the Bull and Cygnus Fire Alarm Detection System (FADS). Any construction site in London, Essex or Herts using this system needs to check serial numbers and act immediately. Fire detection is non-negotiable on live pour sites where hot works, pumping operations and curing processes create genuine ignition risks.

We flag this to every site manager we work with. A failed fire alarm system on a concrete frame under construction can shut down an entire programme. Check your equipment today.

Fire Doorset Safety Report Raises Compartmentation Concerns

A separate product safety report on Metador Defender Fire Doorsets highlights potential performance issues. Fire doorsets are critical to the compartmentation strategy in the very buildings our concrete forms the structural core of. If doorsets fail testing, the entire fire strategy can unravel — regardless of how robust the concrete frame is.

We urge our clients’ design teams to cross-reference this report against their fire engineering specifications. Concrete provides inherent fire resistance, but it works as part of a system. Every component must perform.

These regulatory and safety updates reinforce a clear direction of travel: greater accountability, tighter documentation and zero tolerance for non-compliant products on UK construction sites. Our team at Mixit will continue to supply fully certified, traceable concrete and keep our clients informed as these requirements evolve through 2025 and beyond.

Frequently Asked Questions

What is a building assessment certificate and who needs one?

A building assessment certificate is issued by the Building Safety Regulator for higher-risk buildings in England, typically those over 18 metres or seven storeys with two or more residential units. The principal accountable person for the building must apply for it.

How do contractors prepare for a BSR inspection on a concrete-framed building?

Contractors should compile all structural documentation from day one, including concrete batch certificates, mix design records and conformity test results. This evidence forms a core part of the building assessment certificate application pack.

Why does the Bull and Cygnus fire alarm recall matter on construction sites?

The recalled system may fail to detect fire, putting workers and partially completed structures at serious risk. Any site using this equipment must verify serial numbers and replace affected units without delay.

What does the BSR charging scheme cover?

It covers fees for building control approvals, inspections, registrations and other regulatory functions carried out by the Building Safety Regulator. Fees are scaled according to building complexity and risk category.

How does concrete traceability support building safety compliance?

Full batch documentation — including strength class, consistence and conformity certificates — provides auditable proof that the structural frame meets design specifications. This traceability is essential evidence during BSR assessments and inspections.
