Five legislative updates landed this month that directly affect how we supply concrete across London, Essex and Herts. The Building Safety Regulator is reshaping its approach to higher-risk buildings, new Approved Documents for 2026 are now published, and resident remediation surveys are formalising data collection. Our team has reviewed every update. Here is what matters for our clients on site right now.
Key Takeaways
- The BSR is shifting to a more proportionate, targeted method for higher-risk building assessment certificates.
- A new BSR improvement plan targets external remediation delays and application caseload bottlenecks.
- Approved Document F (2026) updates ventilation requirements under Part F of the Building Regulations 2010.
- Approved Document L (2026) updates energy conservation requirements under Part L of the Building Regulations 2010.
- A formal privacy notice governs how resident remediation survey data is handled, signalling tighter oversight of post-construction accountability.
BSR Adopts Proportionate Assessments for Higher-Risk Buildings
The Building Safety Regulator has confirmed it will update its approach to building assessment certificates. Rather than applying a blanket methodology, the regulator will now provide greater support for duty holders while keeping safety standards intact, as outlined in the BSR’s announcement on proportionate and targeted higher-risk building assessments.
For us, this matters because our concrete goes into structures that fall under these higher-risk categories—residential towers, mixed-use developments, and large commercial builds. Duty holders who are our direct clients will face clearer expectations. We are already advising project managers to review their assessment timelines and ensure material specifications are documented from pour to completion. Traceability is not optional. It is the baseline.
BSR Tackles External Remediation Delays Head-On
Delays to remediation works on higher-risk buildings have been a persistent pain point across the sector. The BSR has now published a comprehensive improvement plan to reduce those delays and improve how it manages application caseloads, detailed in the BSR’s external remediation improvement plan.
We see the knock-on effects of remediation delays weekly. Concrete orders get pushed back. Pour schedules slip. Contractors absorb costs they did not budget for. This plan should shorten approval windows and give our clients more predictable project timelines. Our scheduling team is factoring these changes into forward planning for Q3 and Q4 2025 deliveries.
Approved Document F (2026): Ventilation Standards Are Changing
The updated Approved Document F (2026) supporting Part F of Schedule 1 to the Building Regulations 2010 sets out revised ventilation requirements. Concrete mix design, slab thickness, and structural layouts all influence ventilation performance in finished buildings. We work closely with architects and structural engineers to ensure our mixes support compliance with these standards.
Contractors should review the 2026 document now. Waiting until enforcement begins creates risk. We recommend integrating ventilation considerations into early-stage structural planning, particularly for basement pours and ground-floor slabs where air movement is most constrained.
Approved Document L (2026): Energy Conservation Gets Stricter
Alongside Part F, the government has published the Approved Document L (2026) supporting Part L of Schedule 1 to the Building Regulations 2010. Part L governs energy conservation. For concrete, thermal mass is a selling point—our mixes already contribute to energy efficiency in well-designed buildings.
We expect demand for thermally optimised concrete specifications to increase as these standards take effect. Our technical team is ready to advise on mix designs that help projects meet Part L targets without compromising structural performance.
Resident Remediation Surveys Now Governed by Formal Privacy Framework
The government has published a privacy notice for the Residents’ Experience of Remediation Survey, covering how data from residents living through remediation works is collected, stored and protected. This signals a more structured approach to accountability across the remediation pipeline.
For our clients managing remediation projects, this means resident feedback is being formally tracked. Poor material choices, delays, and quality issues will surface in official data. We treat every delivery as if it will be audited—because increasingly, it will be.
These five updates collectively tighten the regulatory framework around higher-risk buildings, ventilation, energy performance, and remediation accountability. Our team is already adjusting processes across ordering, scheduling, and technical advisory services. Contractors and developers working with us across London, Essex and Herts can expect proactive guidance on compliance as these changes roll into live projects through 2025 and 2026.
Frequently Asked Questions
What is the BSR’s new approach to higher-risk building assessment certificates?
The Building Safety Regulator is moving to a more proportionate and targeted assessment method. This gives duty holders clearer guidance and greater support while maintaining strict safety standards for higher-risk buildings.
How do the 2026 Approved Documents affect concrete suppliers?
Approved Documents F and L (2026) update ventilation and energy conservation requirements respectively. Concrete mix design, thermal mass properties, and structural detailing all need to align with these revised standards from the point of specification.
Why does the BSR’s remediation improvement plan matter for construction timelines?
Remediation application delays have caused widespread scheduling disruption across the sector. The BSR’s new plan aims to cut approval bottlenecks, giving contractors and suppliers like us more reliable project timelines for material delivery and pours.
What is the Residents’ Experience of Remediation Survey?
It is a government survey collecting data from residents living in buildings undergoing remediation. A formal privacy notice now governs how that data is handled, increasing transparency and accountability across the remediation supply chain.
How should contractors prepare for Part F and Part L changes in 2026?
Start reviewing the published Approved Documents now and discuss specification adjustments with your concrete supplier. Early-stage planning that accounts for ventilation and thermal performance avoids costly redesigns later.
