## Summary

Nuclear Restoration Services Limited, a sub-central government public authority located in Warrington, has announced a planned procurement process titled "Upgrade of Switchgear & LV Distribution Network." This project is in the planning stage as of 21 May 2026 and falls under the works category, specifically relating to electrical engineering installation works and equipment. The procurement process aims to address the electrical distribution network at the Dounreay Site, with all preparatory works projected to begin by 30 June 2027 and potentially continue until 31 May 2034. More information regarding market engagement is expected to be available by 1 October 2026.

This procurement presents notable opportunities for businesses, particularly those involved in electrical engineering and installation services. Given its substantial financial scope, ranging from £50,000 to £1.2 million per project phase, the contract is well-suited for SMEs that can offer innovative solutions and manage phased upgrades in infrastructure. Companies experienced in managing co-dependent low voltage electrical projects and legacy switchboard replacements will find this tender particularly appealing, offering a significant avenue for business growth and development within the UK infrastructure sector.

## Notice

A recent survey and subsequent high level electrical distribution strategy concerning operationally restricted (OR) low voltage (LV) switchgear across the Dounreay Site has been developed. The scope of works encompasses primary supply to 23 facilities containing the OR assets and a further two cost estimates for common containment of electrical supplies within the FCA perimeter and replacement of other concern legacy switchboards. From a timescale perspective all assets require replacement, but some have a higher priority and criticality than others based on safety, condition and vulnerability within the LV electrical network. Similarly, due to co-dependency of LV electrical supply, some will be grouped and replaced as a common single phased project. Nine of these outputs are phased for proposed completion in the next 5 years and range between PS50k to PS1.2M in value based on initial cost estimation. Details of Market Engagement to follow
