Summary of the contracting process

Yorkshire Water Services Limited is seeking suppliers for a multi-supplier framework covering high-voltage electrical systems and air circuit breakers (ACBs). The four work areas are HV design, installation and protection studies; HV inspection and maintenance; ACB replacement and associated works; and ACB inspection and maintenance. Tasks include design, fault and condition studies, supply and installation, testing, commissioning, reporting, remedial works and asset documentation. The framework is intended to support planned, urgent, reactive and complex work, including safety-critical activities required for the utility’s statutory, regulatory and health and safety obligations. Work is for Yorkshire Water across the United Kingdom.

Yorkshire Water invited suppliers to compete through a multi-stage competitive flexible procedure. The process reached the tender stage: suppliers first face pass/fail Conditions of Participation, with qualifying suppliers invited to submit tenders for evaluation. Suppliers may bid for one or more of the four lots. The expression-of-interest deadline was 30 October 2026 at 12:00 UTC. The framework is scheduled to run from 1 February 2027 to 31 January 2031, with possible extension to 31 January 2035, subject to performance, regulatory requirements and business need. The stated total estimated value is £14.25 million; individual lot values are £8.6 million for HV design and build, £810,000 for HV maintenance, £2.44 million for ACB replacement and £1.084 million for ACB maintenance. Each lot is evaluated 50% on price and 50% on capability and quality.

The opportunity suits specialist electrical contractors and engineering firms with relevant high-voltage or air circuit breaker expertise. Depending on the lot, suppliers need experience in electrical design and protection or fault studies, installation and commissioning, or planned and reactive inspection, testing, maintenance and remedial work. The evaluation rewards a sound technical approach, relevant experience, mobilisation plans, delivery capacity and response times, alongside compliance with Yorkshire Water’s requirements. Suppliers must demonstrate appropriate health and safety arrangements, competent-person capability and operational controls. The participation checks also cover regulatory compliance, financial standing, environmental and human rights practices, quality management, information security, insurance and pre-employment checks. The framework offers a route to planned programmes as well as urgent or complex call-off work, awarded through mechanisms that may include direct allocation, capability-based rotation or further competition.
