Reported terms and dispute process
- Standard payment terms
Payment terms are agreed with suppliers and subcontractors as part of the contract arrangement and invoices must show the order number. Terms very between 7 days where we have some rental invoices and payment is made once the invoice is processed to 60 days from the date of invoices. The most frequent payment term for supplier within the reporting period is 30 days from the date of the invoice with payment to these suppliers generally made after receiving the statement from the supplier.
- Dispute resolution process
Costain Limited actively seeks to resolves disputes by discussing with the relevant suppliers and typically involving members of the relevant projects supply chain, procurement and commercial teams and the relevant accounts or accounts payable team. For major suppliers and subcontractors, central procurement will likely be involved and, where necessary, members of management. Where it is not possible to reach agreement, usually on entitlement in relations to subcontractors, several potential dispute resolution methods may be used, most commonly, mediation or adjudication. If it remains impossible to reach agreement, the items may be referred for litigation.

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.
