## Summary

Portsmouth Water Limited is undertaking a significant procurement process to enhance its Telephony and Resilience capabilities. The procurement, initiated under the UK legislative framework 2023/54, will transition the organisation from PSTN lines to a secure, enduring digital communication infrastructure across its 48 sites. This project is pivotal for critical national infrastructure and aims to meet operational and IT needs from 2026 until at least 2030, with potential extension up to 2035. Tender submission for the competitive flexible procedure closed on 31 October 2025, with a contract award scheduled by 14 November 2025. The scope of work includes enabling seamless connectivity and prioritising critical data traffic, ensuring service reliability across Portsmouth Water's sites in the United Kingdom.

This procurement presents business growth opportunities for suppliers capable of delivering robust telecommunications solutions, particularly those skilled in managing wide area networks and dedicated business telephone systems. Companies with expertise in implementing secure digital communication infrastructure and strong collaborative abilities will find this tender attractive. Given the critical infrastructure focus and the objective of establishing a singular supply chain provider, large-scale enterprises with a track record in utility services are especially suited to compete in this tender. The project not only offers a lucrative financial opportunity, with a gross value of £3,600,000, but it also allows the successful supplier to establish long-term partnerships, extending to future business plan periods with renewal options up to five additional years.
