Summary of the contracting process

NHS Tayside is procuring a high-voltage electrical maintenance service for substations at Ninewells Hospital, Perth Royal Infirmary and Dundee Dental Hospital, across Tayside. The requirement covers planned preventive maintenance and a 24/7 emergency call-out service for high-voltage infrastructure. Planned work includes six-monthly substation inspections and maintenance of switchgear, transformers, ring main units, protection relays, batteries, chargers and earthing systems. The contractor will maintain asset registers and schematic drawings, provide safety and isolation documentation, and supply electronic reports and test results after work. Emergency incidents, including power outages and high-voltage faults, must be responded to within two hours. Additional repair work requires prior quotation and NHS Tayside approval. Community benefits form part of the requirement.

The procurement has reached tender: NHS Tayside invited offers through an open procedure. Bids were to be submitted electronically by 12 October 2026 at 12:00, with bid opening at the same time. The contract is due to start on 1 December 2026 and run for an initial eight years, with an option to renew for a further eight years. The tender sets a contract duration of 2,880 days. Evaluation and participation requirements are set out in the specification, including economic and technical selection information; bidders must provide the names and qualifications of staff assigned to the work, and variants are not permitted. The successful supplier will be selected for a single lot covering all listed hospitals and must submit in English.

This opportunity suits an established high-voltage maintenance contractor able to support critical NHS buildings across Tayside. The supplier needs competent, suitably qualified personnel and the capacity to provide continuous emergency cover, including a two-hour response to outages and high-voltage faults. Experience of substations, high-voltage switchgear, transformers, ring main units, protection systems, batteries, chargers and earthing systems is directly relevant. Delivery must comply fully with Scottish Health Technical Memorandum 06-03, the mandatory safe system of work for NHS Tayside. The contractor will need robust health and safety, risk assessment and method statement processes, planned maintenance systems, asset-register and drawing management, and reliable electronic reporting. It must also support performance monitoring, attend bi-monthly high-voltage working group meetings and deliver the required community benefits.
