Retention circumstances
In general, if retentions clauses are included in the client contract, we step down the same terms to the subcontractor. This to align retention arrangements throughout the contracting chain to ensure that retention terms applied to subcontractors are no more onerous than those imposed by the client.
Retention parity policy
In general, the business operates a back-to-back retention policy. Retention clauses in qualifying construction contracts with subcontractors are reviewed to ensure they are no more onerous than the retention terms applied by the client on the same project, including retention percentages, release dates, and release conditions.
Retention release
The business adopts retention provisions aligned with recognised industry standard forms of contract and ensures that retention terms applied to subcontractors are no more onerous than those imposed by the client on the same project. Retention percentages, release stages and payment processes are clearly defined within contract documentation. Subcontractors are required to submit the agreed payment application and supporting documentation to demonstrate that contractual requirements have been met, following which payments are reviewed and processed in accordance with the contract terms. The business seeks to ensure that retention arrangements are transparent, proportionate and consistently applied across its projects.

This is a company-submitted statutory disclosure, not a credit rating. BritDB preserves the reporting period and links the report only through the Companies House number supplied by the official service. Percentages describe payments made during that period and may change in later reports.

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
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.
08 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.
09 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.
10 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.
