ISCC certification proves that sustainable material really is sustainable — that feedstock meets the required criteria, that volumes are correctly accounted for, and that every operator in the chain can evidence it.
We prepare UK producers, traders, waste collectors and brand owners for ISCC EU, ISCC PLUS and CORSIA audits, with the mass balance systems, sustainability declarations and supplier controls that certification bodies examine most closely.
Scope of the engagement
- ISCC EU readiness
- Preparation for certification under the EU renewable energy rules, covering sustainable feedstock, greenhouse gas savings and chain of custody for UK operators trading into Europe.
- ISCC PLUS and circular materials
- Certification support for recycled and bio-based content claims in plastics, chemicals and packaging, including mass balance and attribution methods.
- CORSIA and aviation fuel
- Readiness for the aviation offsetting scheme, where accurate sustainability declarations and life-cycle emissions data are essential.
- Chain of custody and mass balance
- Bookkeeping systems, conversion factors, volume reconciliation and internal controls that keep certified and non-certified material separated.
- Supplier and waste declarations
- Supplier onboarding, declaration checks and waste-origin evidence for collectors, processors and traders across the supply chain.
- Audit preparation and follow-up
- Mock audits, document packs and on-site support for the certification body's visit, plus corrective action close-out afterwards.

How the engagement runs
- 01
Eligibility review
We confirm which ISCC scheme fits your materials, markets and position in the supply chain before any documentation is written.
- 02
System design
Mass balance methodology, material flows, conversion factors and responsibilities documented in a system your operators can follow.
- 03
Supplier evidence
Declaration collection, sustainability proofs and supplier audits where the scheme requires them.
- 04
Internal audit
A full mock audit against the scheme requirements, with findings closed before the certification body is invited.
- 05
Certification and surveillance
Support through the certification audit, plus annual surveillance readiness as volumes and suppliers change.
What UK auditors and buyers expect
Trading into Europe
UK producers and traders supplying EU markets need evidence that satisfies European auditors — we prepare documentation to that standard.
Recycled content claims
ISCC PLUS supports credible recycled content claims under increasing UK scrutiny of green marketing statements.
Waste and residue operators
Collectors and processors get help with origin evidence, permits and the classification issues auditors question most often.
