Construction Products Reform White Paper 2026: What UK Contractors Need to Know About the New General Safety Requirement
On 25 February 2026, the Ministry of Housing, Communities and Local Government (MHCLG) published what may be the most significant piece of construction regulation since the Building Safety Act 2022 itself: the Construction Products Reform White Paper. Alongside it came a formal consultation on a new General Safety Requirement (GSR) for construction products — a requirement that will, for the first time, bring all construction products within the regulatory regime.
If you're a contractor, manufacturer, principal designer, or anyone involved in specifying, procuring, or installing construction products on UK sites, this affects you directly. Currently, only around one third of construction products on the UK market are covered by designated standards. The remaining two thirds sit in a regulatory blind spot. The White Paper aims to close that gap permanently.
In this comprehensive guide, we break down every key proposal, explain what it means for your day-to-day operations, and outline the practical steps you should be taking right now.
Why Construction Products Reform Matters Now
The Grenfell Tower tragedy of 2017, which claimed 72 lives, exposed catastrophic failures in how construction products were tested, marketed, and installed. The subsequent Grenfell Tower Inquiry, the Dame Judith Hackitt Review, and the Morrell-Day Review all identified systemic weaknesses in the construction products regulatory framework.
The Building Safety Act 2022 laid the legislative foundation, establishing the Building Safety Regulator (BSR) and introducing the concept of duty holders with clear accountability. But the regulation of construction products themselves — the physical materials that go into our buildings — remained incomplete.
The White Paper represents the Government's comprehensive response. Published alongside the first Annual Report on Grenfell Tower Inquiry recommendation implementation, it signals that the era of self-regulation for construction products is decisively ending.
The General Safety Requirement: A Paradigm Shift
The centrepiece of the White Paper is the proposed General Safety Requirement (GSR). This is not a minor tweak — it fundamentally changes the regulatory landscape for construction products in the UK.
What the GSR Requires
Under the GSR, manufacturers will be required to:
- Assess safety risks connected to the intended use and normal or reasonably foreseeable conditions of use of their products
- Take proportionate action to eliminate or control such risks before placing products on the market
- Provide clear, accessible, and accurate product information
- Maintain documentation demonstrating compliance
Importers and distributors will also face new obligations to support product safety throughout the supply chain. This means that if you're sourcing materials from overseas suppliers, you'll need to verify that the products you're bringing into the UK meet the new requirements.
Two Regulatory Tracks
The White Paper establishes two clear tracks:
- Products covered by a designated standard: It remains mandatory for manufacturers to declare performance in line with the designated standard, affix the appropriate product mark, and provide compliance documentation. This continues the existing regime but with strengthened enforcement.
- Products NOT covered by a designated standard: These products — currently the majority — will now fall under the GSR. Manufacturers must conduct risk assessments and demonstrate that their products are safe for their intended use.
The consultation on the GSR runs until 20 May 2026, with secondary legislation expected by the end of 2026 and the regulations coming into force in late 2027.
Enhanced Requirements for Safety-Critical Products
The White Paper goes further for products deemed critical to safe construction — products whose failure presents a direct risk to life. Fire doors, cladding systems, structural fixings, and insulation materials are likely to fall into this category.
Duty Holder Responsibilities
For these safety-critical products:
- Principal Designers bear responsibility for ensuring that what is specified and installed is suitable and safe for the intended use
- Principal Contractors are responsible for ensuring that installation is carried out correctly and appropriately
- The national regulator will determine which products or systems are classified as critical to safe construction
- Specific "safety critical scenarios" will be defined with corresponding guidance
This directly connects to the duty holder framework established under the Building Safety Act and overseen by HSE. If you're already operating under the higher-risk building regime, these enhanced product requirements will become an additional layer of compliance.
Maintaining Alignment with the EU Regime
In a pragmatic move, the Government has confirmed its intention to retain consistency with the EU's new Construction Product Regulation (EU) 2024/3110 where this meets UK safety objectives. Key implications include:
- CE-marked products compliant with the EU regime will continue to be accepted in Great Britain without retesting or additional marking
- The Government intends to align timescales with the EU where possible to mitigate risks of regulatory divergence
- The Windsor Framework provisions for Northern Ireland are maintained
For contractors and manufacturers who operate across UK and EU markets, this alignment reduces the burden of dual compliance — though you'll still need to monitor both regimes for any areas of divergence.
The National Regulator for Construction Products
The White Paper confirms the creation of a national regulator for construction products, building on the existing Building Safety Regulator's remit. On 2 February 2026, the BSR officially became a standalone body — a significant step toward establishing a single construction regulator in England.
The national regulator will be responsible for:
- Determining which products are critical to safe construction
- Defining safety-critical scenarios and guidance
- Enforcement of the GSR and designated standard requirements
- Market surveillance and product testing
- Maintaining a public test-data library for improved transparency
The regulator will bring together 10 of the 12 functions identified by the Grenfell Tower Inquiry, including building control oversight, strengthened construction products regulation, and new approaches to professional oversight such as licensing principal contractors for higher-risk buildings and mandatory accreditation of fire risk assessors.
Product Information, Labelling, and the Digital Thread
Improved transparency is a cornerstone of the reforms. Manufacturers and economic operators will be required to provide:
- Clear and accurate product information accessible to specifiers and installers
- Standardised labelling that enables informed decision-making
- Digital product information that can feed into the golden thread of building information
This connects directly to the golden thread requirements under the Building Safety Act. If your organisation is already maintaining digital records of building information — as required for higher-risk buildings — the enhanced product information requirements will strengthen that data chain.
Tools like BRCKS can play a vital role here. When your site teams need to communicate about product specifications, substitutions, or compliance queries, having a dedicated construction communication platform ensures that critical product information is captured, shared, and traceable. Rather than relying on scattered WhatsApp messages or emails that disappear into inboxes, a purpose-built tool keeps your product compliance communications organised and auditable — exactly what the new regime demands.
The Building Safety Levy: Coming October 2026
While not part of the White Paper itself, it's worth noting that from 1 October 2026, a new Building Safety Levy will be charged on all new residential developments requiring building control approval in England. This levy funds the remediation of unsafe cladding on existing buildings and adds another financial consideration to project planning.
Combined with the product reform requirements, the levy underscores the Government's commitment to funding and enforcing building safety improvements across the sector.

What This Means for Your Business: Practical Steps
Whether you're a main contractor, specialist subcontractor, manufacturer, or consultant, the Construction Products Reform White Paper demands action now — not when the regulations come into force.
For Contractors and Principal Contractors
- Audit your supply chain: Identify which products you regularly specify or install that currently fall outside designated standards. These will be the products most affected by the GSR.
- Review procurement processes: Ensure your procurement documentation requires suppliers to provide evidence of product safety assessments, even ahead of the formal requirement.
- Train your teams: Site managers and supervisors need to understand the enhanced duty holder responsibilities for safety-critical products. CIOB and RICS offer relevant CPD programmes.
- Strengthen communication: Ensure product specification changes, substitutions, and compliance queries are documented and traceable. Visit the BRCKS blog for more guidance on construction communication best practices.
For Manufacturers and Suppliers
- Begin risk assessments now: If your products aren't covered by a designated standard, start conducting safety risk assessments using the framework outlined in the GSR consultation.
- Prepare documentation: Build the evidence base for product safety that the GSR will require.
- Respond to the consultation: The deadline is 20 May 2026. Your input will shape the final regulations. Respond via Citizen Space or email ConstructionProducts@communities.gov.uk.
For Principal Designers and Specifiers
- Review specification practices: Ensure you can demonstrate that specified products are suitable and safe for their intended use — your duty holder responsibility under the enhanced regime.
- Document everything: The golden thread requires comprehensive records. Every product decision, substitution, and approval should be recorded digitally.
Responding to the Consultation
The GSR consultation is open until 20 May 2026 and the Government is actively seeking input from across the construction industry. Whether you're a sole trader, an SME, or a major contractor, your perspective matters.
