Demonstrated progress

* Improving and update training programmes, pushing for completion * Encouraging people to report issues they see, 24/7 safe call service to NDA ethics team. * KPIs being incorporated into all contracts and are monitored, met and improved upon. * Meet any new requirements in the new regulations. * Continue to meet the 6/6 government guidelines.

Reported risks and mitigations

  • Risk: Due to the nature of the goods and services we procure our exposure to modern slavery risk is relatively low. Minor spend areas like PPE pose a threat since materials may come from high risk countries
  • Area: Within your supply chains
  • Tier: Tier 1 suppliers Tier 2 suppliers Tier 3 suppliers and below
  • Risk: NWS is conscious that construction presents a medium risk with regard to modern slavery. Given some active major procurement in this area we are increasing due diligence / assurance activities

A registry entry records what the organisation declared in its statement. It is not an independent audit. Group statements can cover several companies; BritDB preserves each exact source-supplied company-number link and excludes approver names and email addresses.

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

Snapshot 29 September 2026
CCEW

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.

i

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

Snapshot 29 September 2026
CCNI

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.

i

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

Report 8 October 2026
UKSL

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

Snapshot 29 September 2026
i

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

Snapshot 29 September 2026
EA

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.

i

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.
