Demonstrated progress

Each year we set goals based on our risk assessment. The statement sets out progress against actions identified in the previous statement and the actions set for the current year.

Reported risks and mitigations

  • Risk: Contract workers employed at Smiths manufacturing sites in higher risk modern slavery jurisdictions (as determined using the Global Slavery Index)
  • Area: Within your own operations
  • Group: Women Migrants Children
  • Location: United Arab Emirates China Indonesia India Malaysia Thailand Tunisia
  • Mitigation: We perform audits of sites in higher risk countries to make sure our key policies are being complied with. For example, in relation to overtime, the use of recruitment agents, and ensuring if we have anyone working at the sites between the ages of 16 and 18 their roles comply with UN guidelines.
  • Risk: Modern slavery risks arising through the use of labour and recruitment agencies.
  • Group: Migrants
  • Location: United Arab Emirates China Indonesia Mexico Thailand
  • Mitigation: We have an established process and procedure for vetting recruitment agencies and conduct annual targeted internal human rights risk assessments to include a survey of our engagement with recruitment agencies.
  • Risk: Risks associated with the purchasing of electronic components in higher risk territories
  • Area: Tier 1 Suppliers
  • Group: Women Migrants
  • Location: India Malaysia
  • Mitigation: We address this risk through auditing key suppliers, and educating our staff in the region on red flags and what to watch out for.

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.

10 Charity register

Charity Commission links

Snapshot 25 August 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.

11 Northern Ireland charity register

Snapshot 25 August 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.

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.

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.
