UK REACH Deadlines Extended: DEFRA Publishes Consultation Response (December 2025)
The UK chemicals regulatory landscape is evolving again. On 22 December 2025, the UK Department for Environment, Food & Rural Affairs (DEFRA) officially published the outcome of its public consultation on extending UK REACH submission deadlines.
This announcement is highly relevant for manufacturers, importers, and downstream users preparing for upcoming compliance obligations under the UK REACH framework.
Background: DEFRA Consultation on UK REACH Deadlines
DEFRA launched a public consultation on 14 July 2025, which remained open until 8 September 2025. The consultation explored several options to adjust the transitional registration submission deadlines introduced after Brexit.
The main objective was to balance regulatory oversight with the practical burden faced by industry, especially smaller businesses.
Government Decision: Option 1 Confirmed
In its response, DEFRA confirmed that the government will proceed with Option 1, as originally proposed.
According to the official statement, the additional time provided will:
- Reduce pressure on small and micro-enterprises
- Support downstream users
- Ensure that safety data become available at the right time for regulatory review
This is a significant step toward easing the administrative load while maintaining chemical safety standards.
New UK REACH Submission Deadlines (Extended)
The revised deadlines under Option 1 are now confirmed as follows:
| Deadline | Annual Tonnage Band |
| 27 October 2029 | 1,000 tonnes or more per year |
| 27 October 2030 | 100 tonnes or more per year |
| 27 October 2031 | 1 tonne or more per year |
These changes provide industry with several extra years to prepare robust dossiers and gather required data.
Compliance Checks Also to Be Aligned
DEFRA also announced its intention to align statutory compliance check dates under Article 41(5) with the new submission deadlines. This alignment will ensure that enforcement and compliance assessments remain consistent with the extended timetable.
Next Steps: Legislation Expected in 2026
The UK government plans to introduce the necessary legislation in 2026, following the ordinary parliamentary procedure. The updated deadlines are expected to enter into force well before the first extended deadline in October 2029.
Key Takeaway for Businesses
Companies operating under UK REACH should use this extended timeline strategically. Early planning remains essential to avoid last-minute compliance risks.
