Summary of the contracting process

The National Audit Office bought business telecommunications connectivity services from Gamma Telecom Ltd: SIP trunking, internet access and Operator Connect data lines. The requirement covers the provision of these connected services for the NAO, with delivery stated as within the United Kingdom. This is a focused connectivity requirement rather than a general information technology services contract. Suppliers whose core business is providing and managing SIP, internet and Operator Connect connectivity are the closest fit. The named services give a clear indication of the type of telecommunications provision the buyer has purchased.

The procurement is complete and was awarded to Gamma Telecom Ltd on 20 March 2023. It was a selective call-off from a framework agreement, Crown Commercial Services G Cloud 13. The response deadline was 28 February 2023 at 12:00 UTC. The contract began on 28 April 2023 and, after two extensions, is due to end on 27 April 2028. The awarded value for the full five-year term is £482,622.12 including VAT, based on an annual value of £96,524.424 including VAT. The published information identifies no evaluation criteria or scoring basis. There were no lots: the connectivity services were procured as one requirement.

This award demonstrates demand from the National Audit Office for a supplier able to provide SIP trunking, internet connectivity and Operator Connect data lines as a coordinated service. A credible competitor for a future requirement of this kind would need proven telecommunications capability across all three service areas, and the operational capacity to support a public-sector customer across UK delivery locations. The selected supplier was a large company, and the procurement used a framework call-off route; suppliers seeking comparable work should therefore be equipped to deliver at this scale and to compete through the relevant framework route. The requirement is specifically for connectivity services, not broader IT support.
