Journey
Construction materials regulatory compliance
Learning path covering the regulatory obligations for construction materials in Great Britain. Understand product marking (CE and UKCA), hazardous materials management under COSHH, aggregate levy, and timber sourcing compliance.
What you will learn
Construction materials are subject to multiple regulatory regimes covering product safety, worker health, environmental levies, and sustainable sourcing. This learning path takes you through each obligation so you understand what applies to your business.
- How CE and UKCA marking works for construction products after the 2025 regulatory changes
- Your duties under COSHH when handling hazardous materials such as cement, silica dust, and solvents
- When aggregate levy applies and how to claim exemptions for recycled materials
- Timber sourcing due diligence under the UK Timber Regulation
- How to use the compliance checklist to verify your obligations are met
Each step builds on the previous one, starting with product marking and ending with a practical checklist.
-
Understand the materials compliance landscape
Construction materials in Great Britain are regulated under several overlapping frameworks. The key ones are:
- Construction Products Regulation (CPR) - requires CE or UKCA marking for products covered by harmonised European standards, ensuring they meet declared performance characteristics
- Control of Substances Hazardous to Health (COSHH) 2002 - requires assessment and control of risks from hazardous substances used on construction sites
- Aggregate Levy - a per-tonne tax on virgin sand, gravel, and rock used in construction
- UK Timber Regulation (UKTR) - requires due diligence to ensure timber is legally harvested before placing it on the GB market
Non-compliance with any of these can result in enforcement action, fines, or criminal prosecution. The following steps explain each obligation in detail.
-
Comply with construction product marking requirements
CE marking continues to be recognised for construction products placed on the Great Britain market until further notice, and UKCA marking remains voluntary - this has been government policy since September 2023, resolving years of uncertainty about whether businesses would need to switch to UKCA-only marking. From 8 January 2026, the Construction Products (Amendment) Regulations 2025 additionally recognise products complying with the new EU Construction Products Regulation 2024/3110 as satisfying the GB regime.
If you manufacture, import, or distribute construction products covered by a harmonised European standard, you must ensure those products carry a valid CE or UKCA mark and are accompanied by a Declaration of Performance (DoP).

Manage hazardous construction materials
Many common construction materials pose health risks. Wet cement causes dermatitis, cutting concrete generates silica dust that causes silicosis, and solvents emit harmful vapours. The COSHH Regulations 2002 require you to assess the risks from every hazardous substance on your sites and implement controls. This applies regardless of business size.

-
Understand aggregate levy obligations
The aggregate levy is a per-tonne environmental tax on virgin rock, sand, and gravel exploited commercially in the UK. If you extract or import aggregates, you may need to register with HMRC. Recycled and secondary aggregates are generally exempt.
-
Meet timber sourcing due diligence requirements
The UK Timber Regulation (UKTR) requires anyone placing timber on the GB market for the first time to exercise due diligence to ensure it was legally harvested. Due diligence involves gathering origin information, assessing the risk of illegality, and mitigating any risks identified. Records must be kept for five years.
-
Verify your compliance
Use the construction materials compliance checklist to confirm you are meeting all your obligations. The checklist covers each regulatory area in a format you can work through systematically, either when setting up new processes or as a periodic review.

Summary
You now understand the key regulatory obligations for construction materials in Great Britain. Use this summary to confirm your readiness:
- I know whether my products need CE or UKCA marking and I have valid Declarations of Performance
- I have COSHH assessments for all hazardous substances used on my sites
- My workers are protected from silica dust exposure with appropriate controls and RPE
- I understand whether I need to register for aggregate levy
- I have due diligence procedures for timber sourcing where I am the first placer on the GB market
- I have completed the materials compliance checklist
