We make sure that we adhere to the law, our policies and licenses, and behave in line with our core values of respect, commitment and teamwork. Our policy is to buy goods and services competitively, economically, fairly, ethically and efficiently. We carry out due-diligence checks on all Suppliers and, as an Xoserve Approved Supplier, we expect you to conduct your business in line with our values and in accordance with our Supplier Code of Conduct. This document will be issued to new Suppliers before any goods/services are awarded, and annually to all existing Suppliers. If you would like to request a copy please contact the P2P team. Becoming an approved supplier To become an Approved Xoserve Supplier you will need to pass our due-diligence checks and complete a Supplier Application Form sent to you by your Xoserve Contact. Once we have received a completed Supplier Application Form we will be able to issue you with a Purchase Order (PO) for any contracted work. Purchase orders Xoserve operates a 'No Purchase Order, No Payment’ approach. If you have been asked to provide any goods and services to Xoserve but have not received a Supplier Application Form or a PO number, please do get in touch with the P2P team or your Xoserve Contact and we will investigate the matter further.
