## Summary

Northern Ireland Water Limited is procuring maintenance services for hydro turbines at three of its sites in Northern Ireland. The work is machinery repair and maintenance, supporting the continued operation of the utility’s hydro turbines. The requirement is presented as one contract covering all three sites, rather than separate site-based packages. Suppliers whose work includes maintaining and repairing hydro turbine equipment are the most directly relevant. The buying organisation is Northern Ireland Water Limited, a water utility based in Belfast.

The buyer invited offers through an open competition under the utilities regime. The contract is a single lot, with evaluation weighted equally between price and quality. The enquiry deadline was 23 October 2026 at 23:59, and the bid submission deadline was 30 October 2026 at 12:00. The stated contract period runs from 1 April 2027 to 31 October 2030, with provision for two extensions of up to 12 months each, giving a maximum possible end date of 31 October 2032. The estimated contract value is £108,000 including VAT. The contract also allows the buyer to purchase additional goods or services during the contract period, as described in the specification.

This requirement is suited to suppliers with the practical engineering capability to inspect, maintain and repair hydro turbines, and to deliver that work across three Northern Ireland Water sites. Bidders should be able to explain how their technical approach and service quality meet the specification, as quality accounts for half of the evaluation alongside price. The multi-year term may suit businesses able to provide consistent maintenance support over an extended period, with capacity to respond to additional purchases if required. The requirement is framed as a single package, so suppliers should be equipped to cover the three-site scope themselves or organise delivery across those locations.
