Maximum contractual payment information
There were no changes to standard payment terms in the reporting period. Our invoice and payment processes have continued in a remote working environment since early 2020. We ask all suppliers to provide invoices and statements in electronic format by email.
During the reporting period, we have continued to include cleared approved invoices for all suppliers on weekly payment runs and these include all invoices matched to statements.
Reported terms and dispute process
- Standard payment terms
Payment terms are agreed with suppliers and subcontractors as part of the contract arrangements and invoices must show the order number. Terms vary from 21 days where payment is made once the invoice is processed to 45 days from date of invoice. The most frequently used terms for suppliers in the reporting period are 30 days from the date of invoice with payment for these suppliers generally made after receipt of a statement from the supplier and a reconciliation of the account.
- Dispute resolution process
Costain Oil Gas & Process Limited actively seeks to resolve disputes by discussing them with the relevant supplier(s), typically involving members of the relevant project’s supply chain, procurement or commercial teams and the relevant accounts or accounts payable team. Where necessary members of management will be involved.
Where it is not possible to reach agreement, usually on entitlement in relation to subcontracts, a number of potential dispute resolution methods may be used, most commonly, mediation or adjudication. If it remains impossible to reach agreement, the items may go to litigation.

As a construction business: each site conducts monthly site inspections, this includes working conditions, ethics etc.
Demonstrated progress
We continue to increase the extent of our supply chain engagement, supplier training and the training of our own employees. Continuing to raise awareness of unethical labour practices, how to identify them and how to respond are fundamental to combating the issue.
Reported risks and mitigations
- Risk: Availability of skilled and unskilled labour - particularly with the uncertainty of Brexit market forces.
- Area: Within your supply chains
- Tier: Tier 1 suppliers Tier 2 suppliers Tier 3 suppliers and below
- Group: Migrants
- Mitigation: During 2020 a scenario-based assessment was undertaken to understand the risks of Brexit to Costain’s business operations. As part of this exercise, we engaged with our suppliers to understand their approach to Brexit risk management and to find out about their mitigation plans, particularly in respect to the availability of migrant labour and materials.

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.
08 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.
09 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.
10 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.
11 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.
12 Environmental register
Environment Agency waste registrations
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.
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.
