Retention circumstances
Urenco construction contracts are generally delivered on model form contract terms and conditions, such as NEC and IChemE. These model form contracts have retention clauses embedded within them to support robust delivery management of all the contractual obligations, and more importantly proactive defect management. e.g. Urenco will retain a percentage of all application for payments (usually 5% of the application for payment total) until formal completion of the contract. Upon completion of the contract, 50% of the retained monies are released back to the supplier based on successful completion of the contract deliverables, and more importantly with no defects having been identified at the point of contractual completion.
The remaining retention monies (usually 2.5% of the contract sum) is then retained by Urenco for the duration of the defect liability period. The defects liability period is usually 12 months from actual completion of the contract, but this can be negotiated on a contract-by-contract basis. Upon the defect liability period coming to an end; the supplier issues a defects certificate to Urenco confirming that there are no defects. Once this certificate has been confirmed by Urenco, the remaining retention monies (2.5%) are released back to the supplier. This is standard practice for construction contracts to ensure that any identified defects are proactively managed.

Demonstrated progress
Due diligence had primarily focused on Commercial / uranics counterparties and suppliers. During 2020 we broadened the scope to other critical suppliers such as procurement, information technology and maintenance and continue to assess the modern slavery risks that may arise within these areas. The Enterprise Risk Management processes have been updated to ensure keys risks associated with modern slavery are identified and reviewed on an annual basis.

These are candidate company associations. The public-register downloads do not supply Companies House numbers. BritDB requires one unique exact holder-name and postcode match; the regulated site may differ from the registered office, so verify the record at source.

PSC records are company-filed public-register information. When the exact same displayed individual name occurs at multiple companies, BritDB offers a non-indexed cross-reference page. It is a name match only, not proof that the records describe the same person. Service addresses and partial dates of birth are deliberately omitted.
07 Charity register
Charity Commission links
No exact company-number link in this snapshot
The Charity Commission extract did not explicitly associate this Companies House number with a charity. BritDB does not use a name-only match to fill the gap.
This company-level check covers the Charity Commission for England and Wales. Links are accepted only when the official extract supplies this exact company registration number. Scottish charities now have separate OSCR profiles, but OSCR’s bulk fields do not provide a Companies House number, so BritDB does not infer a company link.
08 Northern Ireland charity register
CCNI exact company links
No unambiguous company-number link found
The CCNI source number did not resolve uniquely to this Companies House record. BritDB did not use a name or address match.
CCNI publishes company numbers without a jurisdiction prefix. BritDB links only when the plausible padded UK and NI candidates resolve to exactly one Companies House company.
09 Sanctions screening
UK Sanctions List
No exact business-registration-number link found
The imported UK Sanctions List did not supply this Companies House number as a UK-linked business identifier. BritDB did not attempt a name-only match.
No exact link is not sanctions clearance. UK restrictions can apply through ownership or control even where an entity is not separately named. Always use the current official list and obtain appropriate advice for a legally significant decision.
10 Public procurement
Find a Tender links
These links use only the GB-COH identifier supplied in the procurement record. A company may have other public-sector work that is absent, older, below publication thresholds or published without a Companies House identifier.
11 Environmental register
Environment Agency waste registrations
No exact company-number registration linked
The licensed Environment Agency subset did not contain this exact Companies House number. BritDB did not attempt a name-only match.
This is a privacy-reduced, exact-company subset. The full official register also includes sole traders and applicants without a matching Companies House number. Check the current Environment Agency register before relying on registration status.
