Guidance for Suppliers

We value strong partnerships with our suppliers. This page provides essential supplier guidance to help you navigate our procurement processes and understand our expectations.

OCS Supplier Guidance

New Suppliers

OCS select new suppliers based on their technical ability to deliver according to specification accounting for responsible, ethical and sustainable practices along with social value and environmental considerations.

To become a supplier to OCS you will be asked to complete the OCS due diligence process, including the pre-qualification questionnaire and signing of the OCS terms and conditions and supplier code of conduct. Suppliers providing on-site services and works must also undergo SafeContractor accreditation prior to commencing work.

Only suppliers pre-approved by Procurement will be invited to complete this process.

The SafeContractor portal keeps your records up to date, reducing the risk of losing work due to outdated documentation. Accreditation takes 4-6 weeks, depending on the membership package.

Approved contractors/suppliers appear on our online portal. Existing SSIP members receive a discount with SafeContractor, enhancing growth opportunities within OCS.

OCS Payments

OCS Payments

We operate a strict “No PO, No Pay” policy. Your organisation must have an official Purchase Order (PO) to complete work or deliver goods. Emails or phone calls are not considered valid orders. Invoices without a PO number will not be paid.

To ensure prompt payment you must:

  • Send invoices within 60 days of goods/service delivery.
  • Ensure invoices reference the purchase order number and match the purchase order detail.
  • Ensure invoices are addressed to the correct legal entity and address (e.g. OCS Group UK Limited / OCS M&E Limited).
