What we do

Ten service areas. One scientific standard.

Every engagement is led by a senior toxicologist. Every output carries a defensible scientific narrative — not a templated report. Choose a pillar, or speak with us about a problem that crosses several.

REACH & CLP

Registration, evaluation and classification of substances under EU and UK REACH. We build dossiers that read like science, not paperwork — with weight-of-evidence reasoning that holds up under ECHA scrutiny.

How we work

What working with NexGenTox looks like.

An engagement is a working relationship, not a deliverable handed over at the end. The four phases below describe what that looks like — from the first conversation through to authority engagement and lifecycle support.

01 — INITIAL CONVERSATION

Listen first.

The first response comes from a senior toxicologist — typically with one or two follow-up questions to understand the regulatory question, the data position, and the deadline. From that, we propose a scope and a workable approach.

02 — KICK-OFF

Scope agreed.

Scope, deliverable, timeline and fee structure agreed. The senior toxicologist leading the work has been part of the conversation from the start — the point at which the scope and approach are confirmed and the work begins.

03 — THROUGH THE WORK

Drafts shared as they develop.

Regular updates, working drafts shared for review, and the option to discuss specific scientific questions as they arise. Your team reviews the work as it develops, not only when the final deliverable arrives.

04 — SUBMISSION & BEYOND

Stand by the file.

Authority engagement, response to evaluator questions and challenges, and ongoing support across dossier updates, variations and renewals — the file does not end at submission.

How we price

Pricing matched to the work. Transparent throughout.

Where the scope is defined, we work to fixed fees.

Where the regulatory question is open-ended, the basis is agreed at kick-off and the work is invoiced as it progresses, against the scope set in advance.

Bring us a question. We'll come back with a path.
