In 2025, the UK Government launched a public consultation on extending the UK REACH registration deadlines and presented several options for consideration. In December, a summary report was published, confirming that the first option had been selected and that the amendment would officially enter into force in 2026.
Within this context, The REACH (Amendment) (No. 2) Regulations, which bring the relevant amendment into effect, were officially published in July 2026.
What Are the New Deadlines?
The relevant Regulations will officially enter into force on 6 August 2026. From that date onwards, the following deadlines will apply:
Tonnage Band | Transitional Registration Deadline |
| 27 October 2029 |
| 27 October 2030 |
| 27 October 2031 |
Other Amendments Introduced by the Regulations
- The period applicable to Protected Transitional Imports (PTI) has been extended in line with the updated UK REACH registration timetable.
- The deadlines for HSE compliance checks have also been updated in accordance with the new registration timetable, according to article 41(5):
- 27 October 2030: First registration phase
- 27 October 2032: Second registration phase
- 27 October 2036: Final registration phase
- The 2026 Regulations only extend the registration deadlines. The Alternative Transitional Registration Model (ATRm) has not yet entered into force.
