A Pre-Qualification Questionnaire (PQQ) envelope has been created named “pqq_4763” within Project “project_29297”. This PQQ contains preliminary information relating to the requirement and includes the PME questionnaire for Suppliers to complete.

This eSourcingNI PQQ will close at 3.00pm on 23 October 2026 and NIE Networks are unable to accept submissions after this deadline.

Indivual Consultations

Following the return of completed questionnaires, NIE Networks may wish to explore responses further and/or seek clarification from potential Suppliers through face-to-face meetings or remote discussions. This will provide an opportunity to develop a mutual understanding of any potential issues, risks or challenges associated with the proposed procurement that may not have been previously identified. Where necessary, NIE Networks will provide further information and instructions regarding participation in PME Consultations.

Consultations may consist of a presentation by NIE Networks, followed by an opportunity for Suppliers to raise questions and provide feedback.

Please note that NIE Networks shall conduct Consultations in accordance with the principles of equal treatment, non-discrimination and transparency. To that end, it is important to stress that the structure, specification and all other aspects of the procurement will not be designed to give direct or indirect advantage to any interested party and all information concerning the forthcoming procurement will be

disseminated to all interested parties.

Interested parties will not be prejudiced by any response or failure to respond to this PME Notice or the PME Questionnaire. Participation or non-participation in the PME supplier information event shall not prevent any interested parties from participating in any subsequent procurement process.

ANY FUTURE PROCUREMENT

This PME Notice, and the PME supplier information event, do not constitute a call for competition, selection process or a current tender opportunity. This PME Notice has been produced solely for the purpose of conducting Preliminary Market Engagement. All interested parties will need to express a formal interest in any future tender opportunity in due course. Any future procurement for these requirements will be launched separately and is currently anticipated to commence in early 2027.

Subject to any future procurement, NIE Networks intends to use Achilles UVDB to conduct the Pre-Qualification phase of the process. Depending upon the time of issue of any future procurement, NIE Networks will pre-qualify Suppliers using either Achilles UVDB Qualification System Notice (QSN) governed by the Utility Contract Regulations 2016 or Achilles UVDB Qualifying Utilities Dynamic Market (QUDM) subject to the Procurement Act 2023. Therefore, any interested parties will be required to be suitably registered with Achilles UVDB (www.achilles.com/uvdb/ ↗) to participate in the future procurement process. Suppliers are strongly advised to engage with Achilles UVDB directly and allow sufficient time for the registration process. Additionally, expressing an interest in this Preliminary Market Engagement will not necessarily be a pre-requisite in

respect of the future tender competition.

NIE Networks reserves the right to Direct Award in the absence of competition.

For the avoidance of doubt, Suppliers wishing to participate in this PME exercise must submit their response via eSourcingNI in accordance with the instructions set out above.
