Reported terms and dispute process
- Standard payment terms
Standard payment term is 90 days from invoice date. This period reflects the normal course of dealing, unless the company enters into formal written terms for suppliers from group companies.
- Other payment-term information
Inter-company payments have been excluded from the statistics reported as these are managed through our internal inter-company settlement process and therefore there is no process to report against. These do not in any way affect our speed of paying external suppliers.
- Dispute resolution process

- Procedure
- Single tender action (below threshold)
The supplier link is exact, but the award remains buyer-published procurement data. BritDB requires the GB-COH identifier supplied in the Contracts Finder OCDS release and does not infer suppliers from similar names.
09 Ownership and control
People with significant control
Aon Uk Holdings Limited
- Owns 75% or more of shares
- Controls 75% or more of voting rights
- Can appoint or remove directors
- Notified
- 6 April 2016
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
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.
11 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.
12 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.
