Reported risks and mitigations
- Risk: Long and complex supply chains, including widespread use of subcontracted labour, therefore a high turnover of temporary construction workers, in the UK
- Area: Industry Wide
- Group: Migrants
- Location: United Kingdom
- Mitigation: GRS is committed to partnering with suppliers that adhere to the standards set forth by the Ethical Trading Initiative and the International Labour Organisation. Furthermore, at GRS, we educate our employees about the principal indicators of unethical trade practices and offer a whistleblowing helpline for all employees. Prior to the engagement of any supplier, we carry out a vetting process to ensure they meet compliance standards and continue to monitor them regularly.
- Risk: Industry reliance on migrant workers, resulting in potential language barriers between employers and workers in the UK.
- Mitigation: GRS is committed to partnering with suppliers that adhere to International Labour Organisation standards and applicable UK labour law. GRS fosters a risk-averse attitude across all business areas and implements KPIs to promote and measure the advancement of efforts company-wide. This includes achieving 100% compliance with Right to Work and enhancing awareness of company policies.
- Risk: Subcontractors in the UK construction supply chain may self-regulate labour standards, risking exploitation of low-paid site workers.
- Mitigation: GRS holds those we contract with to appropriate standards. Where a party fails to comply with our expectations or legal requirements, we take remedial action, report concerns as appropriate, and may terminate the trading agreement.

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.
05 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.
06 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.
07 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.
08 Public procurement
Find a Tender links
No exact GB-COH link in this snapshot
Find a Tender did not explicitly identify this Companies House number in a procurement party. BritDB did not attempt a name-only match.
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.
09 Environmental register
Environment Agency waste registrations
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.
