What is being bought

Published requirement description

Supply, install and commissioning of network compatible odorant injection systems

This procurement covers the supply, installation, and commissioning of odorant injection

systems to support operational reliability and compliance across designated gas sites.

The systems are proprietary to the Supplier, requiring a single-source approach to ensure

compatibility and maintain existing infrastructure standards.

Key Deliverables include:

  • Delivery of ZEO odorant injection units with bund risers.
  • Mechanical and electrical installation, including associated materials and pneumatic

lines.

  • Integration of electrical back plates, cabinet lighting, PRU and vent stack.
  • Full retention of existing NJEX systems

Commissioning and Factory Acceptance Testing (FAT) by Supplier.

  • Hazardous waste disposal in line with environmental requirements.
  • Supply and installation of 75m injection line and miscellaneous materials.

Geography and Scale: Deployment spans multiple operational sites within the UK gas

network, ensuring continuity of odorization capability across the region.

Purpose: The upgrade will enhance system reliability, maintain regulatory compliance for

gas odorization, and support safe network operations. Leveraging Supplier proprietary

technology ensures seamless integration with existing assets and minimizes operational risk

Why no open competition

Single Suppliers Intellectual Property Exclusive Rights; Single Suppliers Technical Reasons; Additional Repeat Further Following Competitive Procedure

Published justification

Under Schedule 5, a direct award is permissible where:

  • Only a particular supplier can supply the goods, services, or works required due to technical reasons, and
  • There are no reasonable alternatives or substitutes.

For this case:

  • The odorant injection systems are proprietary to the Supplier, meaning the Supplier

holds exclusive rights and technical know-how for these systems.

  • Integration with existing NJEX infrastructure and compatibility requirements eliminate

the possibility of alternative suppliers without incurring disproportionate technical risk or

operational disruption.

  • The scope includes commissioning and FAT by the Supplier, reinforcing that only

Supplier can deliver the full requirement to specification.

This aligns with the clause in Schedule 5 covering single supplier scenarios due to

exclusive rights or technical constraints. Risks of incompatibility and operational failure if

another supplier were engaged.

The original procurement for initial equipment was competitively tendered for under UCR2016
