Retention parity policy
Retention clauses are used in the majority of our qualifying construction contracts and are included within our standard payment terms but may be negotiated out in certain circumstances.
Retention release
The process for release of money retained under a retention clause is triggered by receipt of an appropriate payment application from the subcontractor; the assessment and payment of sums due is then governed by the payment terms incorporated into the agreed subcontract.
Retention release stages
The most common arrangement is for 50% released at practical completion of the subcontract works and the balance following on the later of either the agreed contractual Retention Release Date or completion of any notified defects.

Reported terms and dispute process
- Standard payment terms
Suppliers are paid net monthly, which is 30 days after the month in which the invoice is received. Subcontractors are paid on average 35 days after payment valuation is received. The company continues to focus on its payment terms for those suppliers with less than 50 employees for whom we are required to pay 95% of invoices within 30 days. During the current reporting period for this supplier group payment performance shows 98% of invoices are being paid within 30 days
- Dispute resolution process
SRM are absolutely committed to fair dealing and fair payment with our supply chain. We also firmly believe that the emphasis of our business dealings is based on genuine, close relationships with our supply chain. These relationships, managed more and more in a structured way, ensure we very rarely have the need for formal dispute resolution processes. Where issues and challenges arise, resolution is hopefully addressed either at the project or procurement team level, dependent upon the nature of the agreement (sub-contract or purchase order). Where resolution cannot be found at this level, there is an escalation process within the business through procurement, finance & / or commercial management to ensure issues and challenges are satisfactorily addressed for both parties. This escalation process goes all the way to Chief Financial Officer at Executive Board level. We really do not expect anything to go beyond this level. Should formal dispute resolution be required, which is extremely unlikely, methods including mediation, adjudication, litigation and / or arbitration may be used.

Demonstrated progress
Progress is illustrated through our verification to BES 6002 and how we work towards agreed objectives as part of that standard. Illustrated by the continuation of our third party audit programme and working with more supply chain partners (cumulatively over the years).
Reported risks and mitigations
- Risk: Workers on lower wages who are then potentially subject to fees and deductions from their wages.
- Area: Within your supply chains
- Tier: Tier 2 suppliers Tier 3 suppliers and below
- Group: Other vulnerable groups
- Location: United Kingdom
- Mitigation: We are working to educate the workforce through measures such as training and site awareness material such as posters and induction slides. We are also working with our supply chain partners to evaluate and assess their processes and procedures.
- Risk: Workers who are engaged multiple tiers down the supply chain, e.g. beyond our tier 1 subcontractors. This is a risk as there is a loss in transparency of how these workers are engaged.
- Mitigation: We are auditing our supply chain partners processes and procedures using a third party auditor.
- Risk: Workers not having any form of written terms and conditions of employment. This means they may not fully understand their rights and what they are entitled too or what their terms of work are.
- Group: Migrants Other vulnerable groups
- Mitigation: We are auditing our supply chain partners to check that their workers are provided with written terms and conditions. As part of this audit, our supply chain partners are asked what they do to check within their supply chains, that workers are provided with written terms and conditions. We are also carrying out site engagement surveys using a third party to speak directly with workers to record their experiences.

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.
