Maximum contractual payment information
This maximum applies only to construction fit‑out contracts. In limited, project‑specific circumstances, different terms may apply where these are expressly agreed as part of the relevant construction or fit‑out arrangement.
Retention circumstances
Retention clauses are used only in limited and project‑specific circumstances, primarily in relation to construction or fit‑out contracts with main contractors. CMNO does not contract directly with subcontractors.
Retention parity policy
Where retention clauses are applied, CMNO uses retention in construction contracts to ensure that any defects or outstanding remedial works are addressed before final payment is made. Retention is negotiated on a contract‑by‑contract basis and generally falls within a range of 3–5%, depending on the nature of the works.
Retention release
Where retention is applied, retained sums are released in line with the relevant construction contract. This typically involves meeting with the contractor to review and confirm completion of any outstanding snagging or remedial items, after which the retained amount is released.

Payment Terms Overview
Standard payment period:
CMNO pays valid invoices within 30 days of receipt.
Invoice must clearly state charges, related services/milestones, and VAT if applicable.
Supplier provides supporting details for verification.
Longest payment period:
Up to 60 days, but only if this is explicitly agreed in the Statement of Work. - Dispute resolution process
Dispute Resolution Summary
Our contracts include a structured, non-binding escalation process:
Level 1: Project Managers attempt resolution.
Level 2: Escalate to Head of Procurement and Supplier lead.
Level 3: Managing Partner and Supplier CEO.
If unresolved after Level 3, the parties may agree to refer the matter to arbitration under LCIA Rules, seated in London, in English. Arbitration is the preferred recourse where appropriate, ensuring fairness and efficiency. Either party may still seek urgent court relief at any time.

This is an exact normalised company-name match, not a registrar-confirmed ownership link. Another legal entity can have the same or a very similar name. UKIPO data is a historical 2018 snapshot; verify the owner and current status before relying on it.
08 Ownership and control
People with significant control
No individual or entity with signficant control
- Notified
- 2 December 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.
09 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.
10 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.
11 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.
