Summary of the contracting process

Northern Ireland Water is actively seeking a vendor for the provision of maintenance services, spare parts, and OEM support for Aerzen Compressors and Blowers. The procurement falls under the category of goods, with a focus on compressors and water distribution services. It takes place in Belfast, Northern Ireland, with the buyer operating under the devolved regulations applicable to Northern Ireland. The tender is in the "active" stage, and the deadline for submission is now extended to 1st April 2026. The procurement utilises a selective method, adhering to a competitive flexible procedure, which aims to appoint a single supplier. The tender is governed by the UK legislation 2023/54, with an award period ending on 14th May 2026 and contract performance slated to commence on 1st June 2026. This document amendment reflects the extension of submission and award deadlines to facilitate vendor applications.

The tender presents notable business growth potential, particularly for companies adept in providing specialised maintenance, compressor systems, and repair services. Companies with expertise in water distribution and sewage treatment machinery are well-suited to compete due to the comprehensive nature of services required. Furthermore, the procurement method favours businesses with flexible and competitive procedures, encouraging participation from entities capable of supplying all required services without needing division into lots. Given the emphasis on cost and quality, companies with established vendor credentials and efficient supply chains can significantly benefit from this opportunity. With a substantial budget, Northern Ireland Water offers a platform for businesses to expand their footprint in the utilities sector through long-term engagement, with optional renewals extending up to 2033.
