Navigating UK REACH can be complex, particularly for companies based outside the UK. UKREACHOR provides expert Only Representative services, IUCLID dossier support, and study monitoring — helping you meet your registration obligations with a clear, technically grounded compliance strategy rather than guesswork.

UK REACH: Defra's ATRm consultation closes on 10 November 2026.
On 29 September, Defra published draft legal text for the Alternative Transitional Registration model (ATRm), presented as a Keeling Schedule showing how UK REACH would read once the amending SI is made.
Defra isn't asking for a simple yes or no. It wants to know where the drafting is ambiguous, incomplete or likely to have unintended consequences, and why.
In our Autumn 2026 UK REACH Update we cover:
If you export to Great Britain, or hold or plan a UK REACH registration, the drafting will affect you, so it is worth reading and responding before the deadline.
More details in our Autumn 2026 Newsletter below.

A company outside the UK who wants to export substances exceeding 1 tonne per year to the UK market will need to appoint a UK-based UK REACH Only Representative (OR).
We can prepare and submit UK REACH Inquiries. Analytical data for substance identity is critical for REACH, we can review this data and/or commission an Analytical Laboratory to produce the required information.
We have substantial experience in using IUCLID for REACH for both Joint and Lead Registrations. We can prepare Robust Study Summaries (RSS) and all other aspects of a REACH dossier.

The ATRm changes what companies must submit at the point of transitional
registration and when additional information may be required. Instead of
demanding complete hazard datasets upfront, the model introduces a staged
approach.
Upfront information will now include:
• Hazard conclusions rather than full study reports
• Existing use and exposure information, with no requirement for
GB-specific expansion
• A targeted chemical safety report, with full risk assessment only where
necessary
• Participation in substance groups to support data sharing and joint
submissions
This reduces the immediate burden on registrants while still giving the
regulator visibility of key risks.

Companies or individuals registering the same substance are matched to a substance group in the ‘Comply with UK REACH’ service. This allows members of the group to access each other’s contact details to:
Study Monitoring
We can help with the selection of a Contract Research Organisation (CRO) to conduct the studies required for REACH. We can review study plans, monitor on-going studies, review reports and complete the IUCLID end-points with the study data.
