Summary of the contracting process

Thameslink Southern Great Northern Limited procured corporate wide area network (WAN) circuit services. The requirement covers the provision and continued operation of communications circuits connecting the organisation’s corporate sites. It is a services contract for wide area network provision, rather than equipment supply or construction. Delivery covers sites in London and the South East of England. The buyer is Thameslink Southern Great Northern Limited, a public undertaking operating in the utilities sector. The requirement is relevant to telecommunications operators, network service providers and managed connectivity specialists able to supply and support business WAN circuits across a geographically dispersed estate. The service needs to support operational business locations, including sites in densely populated areas where circuit replacement would be complex and disruptive.

The procurement has been awarded through a direct award to Vodafone Limited, following a completed procurement process. The contract covers one lot and has an awarded value of £1,644,807 excluding VAT, or £1,973,768 including VAT. The contract period is 1 October 2026 to 30 September 2029. The buyer may purchase or cease circuits as required during the contract. Direct award was justified by the significant cost, time and operational disruption of replacing circuits across many high-population sites, compared with the potential savings from a competitive tender. Independent benchmarking was used to assess value for money and cost efficiency. The selected supplier is Vodafone Limited; the award is recorded as pending and signature was scheduled for 30 September 2026.

This procurement demonstrates demand for managed corporate WAN connectivity across a substantial rail-related operating estate in London and the South East. A credible future competitor would need to provide business-grade wide area network circuits across many sites, manage changes to the circuit estate, and maintain service continuity while minimising disruption to operational locations. The buyer’s rationale places particular weight on the practical difficulty of replacing existing connections, installation time, implementation cost and the effect on operations. Suppliers should therefore be able to demonstrate resilient network delivery, reliable service management, coordinated installation and cessation of circuits, and experience supporting geographically dispersed organisations. Evidence of competitive pricing and independent or transparent benchmarking would also strengthen a supplier’s position when demonstrating value for money.

Notice Description

Corporate WAN circuit provision

Procurement Information

The cost of change to potentially swap all circuits to another provider is a significant undertaking which is not proportionate to potential commercial savings if a tender exercise were undertaken. This is due to a high proportion of the applicable sites being situated in high population areas which would pose a significant impact to time, cost and operational disruption to install new circuits. Independent benchmarking exercises have been undertaken to ensure value for money and cost efficiencies in this extension of services.
