Introduction
For the past few years, the UK REACH Candidate List has remained largely unchanged, while the EU has continued to add new Substances of Very High Concern (SVHCs). As a result, many businesses assumed their existing compliance data would continue to meet UK requirements.
That has now changed.
On 15 June 2026, the UK Health and Safety Executive (HSE) added 15 new SVHCs to the UK Candidate List, bringing it closer to the EU REACH Candidate List. This update creates new compliance responsibilities for businesses that manufacture, import, or supply chemicals, mixtures, and articles in the UK.
Why Is This Important?
SVHCs are substances that may pose serious risks to human health or the environment. When a substance is added to the UK REACH Candidate List, businesses may need to update their compliance documents and provide additional information to customers and regulators. Regularly monitoring the SVHC Candidate List helps businesses stay ahead of these evolving obligations.
For companies supplying both EU and Great Britain, the practical direction is toward greater convergence of SVHC controls. Companies should therefore consider EU Candidate List additions as an early-warning indicator for future UK REACH obligations, rather than waiting until a substance formally appears on the UK list.
Importantly, closer alignment does not mean that UK REACH and EU REACH have merged. Great Britain continues under UK REACH, while EU REACH continues to apply in Northern Ireland under the Windsor Framework. The UK and EU Authorisation Lists also remain legally independent.
If your products contain any of the newly listed SVHCs at or above the 0.1% weight-by-weight (w/w) threshold, you should review your compliance obligations without delay. Maintaining consistent SVHC Compliance across your product range starts with closely tracking this threshold.
Key Actions Businesses Should Take
Review Your Safety Data Sheets (SDSs)
If your non-classified mixtures contain any of the newly listed SVHCs at or above 0.1% w/w, your Safety Data Sheets (SDSs) may need to be updated. Keeping SDSs current helps ensure customers receive accurate safety information. Every UK REACH SVHC addition should trigger a prompt Safety Data Sheet (SDS) Update to keep your documentation audit-ready.
Check Hazard Information
Any newly listed SVHC present at or above the threshold should be clearly identified in the SDS. This improves hazard communication and helps users handle products safely. Staying alert to each UK REACH SVHC update ensures hazard information remains accurate and current.
Assess Articles and Components
If you supply articles or components containing these SVHCs above 0.1% w/w, you may need to notify the UK HSE and provide safe-use information throughout the supply chain. Tracking additions to the SVHC Candidate List and the UK REACH Candidate List helps maintain strong Substance Compliance across your supply chain.
Why Businesses Should Act Now
If you sell products in both the UK and EU, don't assume your existing compliance data is still up to date. A proactive approach to UK REACH Compliance and broader Chemical Regulatory Compliance can prevent costly disruptions.
Now is a good time to review your:
- Product formulations
- Safety Data Sheets (SDSs)
- Chemical Inventory Review
- Supplier Compliance information
- Articles and components linked to the SVHC Candidate List
- Overall UK REACH SVHC exposure across your portfolio
Identifying any compliance gaps early can help reduce regulatory risks and avoid supply chain disruptions.
Conclusion
The latest UK REACH update shows that the UK is continuing to align more closely with the EU on chemical safety requirements. Businesses should treat this as an opportunity to review their products, update compliance documentation, and strengthen their regulatory processes.
