## Summary

Highlands and Islands Airports Limited is the contracting authority for the procurement process titled "Primary Surveillance Radar Maintenance (LSI)" in the category of airport-related activities. This contract focuses on the maintenance of air traffic control systems and equipment at Compass Head, Sumburgh, Shetland. The procurement falls under the services category and is currently at the award stage as of 25th September 2025. The procurement was conducted via a limited method without prior publication of a call for competition, due to the necessity of continuing radar services provided by NATS (Services) Limited, a large-scale supplier. The contract is valued at £65,000 and addresses essential maintenance needs until a replacement radar is installed.

This tender presents significant opportunities for businesses specialising in engineering and maintenance services within the aerospace and aviation sectors. Companies that have expertise in air traffic control systems, radar technology, and related maintenance services would be well-positioned to compete in future procurement processes as HIAL proceeds with radar system upgrades and replacements. This contract extension by Highlands and Islands Airports Limited indicates potential ongoing demand for targeted technical expertise and services, a valuable consideration for businesses looking to expand their market presence in specialised maintenance roles.

## Notice

Contract for the provision of engineering and maintenance services to ensure the safety, efficiency, and reliability of air traffic control systems and equipment at Compass Head, Sumburgh, Shetland. Services include servicing and maintenance of equipment to ensure continued operation whilst replacement radar is sourced by HIAL.

### Lot Information

Lot 1

Requirement is for the continue maintenance of the Primary Surveillance Radar at Compass Head, Shetland. The Compass Head radar is owned and operated by NATS Services Limited; the radar has passed it's operational life expectancy and HIAL is currently undertaking procurements that will provide a replacement so that NATS may decommission the radar. Due to internal restructuring and lack of resources, it has become necessary to re-contract with NATS to provide continued maintenance for the radar for a further 2 years whilst the replacement radar is sourced and installed. This notice serves as a record of the award of that extension without prior competition
