Principality Suppliers

This page is intended for use by our third party suppliers and potential suppliers.

The Principality Suppliers section of the website has been put together by our Procurement team and is designed to furnish third party suppliers and potential suppliers with information to help them better work with the Principality.

As either a supplier or potential supplier to the Principality, it's important for you to have access to the procedures and policies that affect you. Please click on the sections below to learn more.

Purchase of Goods and/or Services

Purchase of goods and/or services

Where the Principality has approached you to supply goods and/or services, you will be asked to provide a copy of official company details to aid in the supplier set up process. This will allow us to make payment due via our preferred BACS method. Undisputed payments will be made in line with our standard payment terms of 30 days.

Where you are asked to supply goods and/or services you may be issued with a Purchase Order to contract on, or Principality will negotiate a written contract with you.

Purchase Order

Where a purchase order has been issued by the Principality for the supply of goods and/or services, the following terms will govern the transaction, unless the Principality has entered into an alternative written agreement with the supplier. Please use the following link to view our Purchase Order Terms and Conditions. Should you have any queries regarding the terms please contact Procurement.


In some circumstances Principality will negotiate a written contract with you to govern our relationship. Where a written contract is entered into, Purchase orders may still be raised to call off against the written agreement.

Supplier Relationship Management

Principality is committed to on-going relationship management with suppliers. As such, from time to time throughout the life of our contractual relationship some extra information may be requested from third party suppliers as part of an on-going due diligence regime, where the level of engagement will be set by the products and or services that are supplied.

Purchase Order Terms & Conditions

Terms and Conditions for purchase of goods and/or services

In order to better control our costs, we have implemented a purchase to pay (P2P) system. This system allows us to raise Purchase Orders (POs) in advance of any goods being delivered or services being provided. Only on receipt of a PO from your contact within Principality should you commence any work on our behalf. Your invoice should quote the PO number. Any invoices received after 6th November 2017 without a valid PO number will be returned to you unpaid. Please read the letter about our PO policy that was distributed to suppliers, which explains the process in more detail.

If you have received a Purchase Order from us, please ensure you have read our terms and conditions for the purchase of goods and/or services. Please use the following link to read our Purchase Order Terms and Conditions.

These terms and conditions will apply to the purchase of any goods and/or services unless the Society has agreed alternative written terms and conditions with you.

Should you have any queries regarding terms between you and the Society, please contact Procurement.
