Extension of substance registration deadlines in UK-REACH 

#UK, #REACH, #GreatBritain, #Extension 

The United Kingdom has decided to extend the deadlines for registering substances under UK-REACH. The new dates are October 2029, 2030, and 2031. 

After leaving the European Union, the United Kingdom developed its own chemical legislation and its own registration system [UK-REACH] for chemicals placed on the domestic market. Registrations of chemical substances, depending on tonnage and hazard posed, were scheduled for October 2026, 2028, and 2030. Because the UK government was not fully prepared to implement all planned solutions, it was decided in December 2025 to extend the registration deadlines under UK-REACH. The new dates are: 

  1. October 2029 
  • Substances included on the Candidate List before 31 December 2023; 
  • CMR substances in quantities of ≥ 1 tonne per year; 
  • Substances very toxic to aquatic organisms in quantities of ≥ 100 tonnes; 
  • All substances in quantities of ≥ 1,000 tonnes; 
  1. October 2030 
  • Substances included on the Candidate List after 31 December 2023; 
  • All substances in quantities of ≥ 100 tonnes; 
  1. October 2031 
  • All substances in quantities of ≥ 1 tonne per year. 

The amended regulations will be adopted in 2026, following standard parliamentary procedure, to ensure that the new deadlines and compliance arrangements come into force well in advance of the first extended deadline in October 2029. The government also intends to enact regulations for compliance checks, ensuring that they are conducted only after registrants have completed their registration. 

The UK-REACH system is modeled on the European regulations with minor changes. It is worth noting that the EU-REACH system remains in force in Northern Ireland. 

What does this mean? 

Entities placing or importing substances onto the UK market will have more time to prepare for the registration process for substances or substances contained in mixtures.
