Summary of the contracting process

The Single Source Regulations Office (SSRO) has recently completed an open procurement for an IT Managed Service (ITMS) and Defence Contract Analysis and Reporting System (DefCARS) contract, valued at £4,753,384. The contract process, initiated by a tender, covers IT services including consulting, software development, internet, and support, and addresses the need for an integrated solution to replace expiring contracts by March 2026. Located in London, the SSRO held a virtual briefing for bidders on the 14th of January 2026, prior to the award stage, which concluded with a standstill period ending on the 8th of May 2026. The procurement under an open procedure was completed with Version 1 Solutions Limited identified as the supplier, ensuring a unified approach for future service benefits and potential cost savings for this public authority of central government with a contract period scheduled from the 1st of June 2026 to the 31st of May 2029, with further extensions available.

The procurement presents thriving business opportunities for organisations specialising in IT services, particularly those adept at managing cloud-based systems using the Microsoft stack. SMEs, especially those in the IT consulting and software development industry, had an excellent opportunity to bid, with 4 out of the final 6 bids coming from SMEs. The SSRO's collaboration with a large enterprise like Version 1 Solutions Limited underscores the significance of robust capabilities in IT management, support, and development for such contracts. Businesses that can provide innovative solutions ensuring seamless connectivity and efficient data analysis will find this contract category conducive to growth, allowing them to contribute actively to governmental technological infrastructure and optimisation.

Notice Title

SSRO IT Managed Service (ITMS) and DefCARS contract

Notice Description

This Invitation to Tender (ITT) is issued by the Single Source Regulations Office (SSRO). The SSRO is conducting this procurement exercise to appoint a suitably qualified and experienced supplier to be its delivery partner to provide its IT Managed Services (ITMS), its Defence Contract Analysis and Reporting System (DefCARS) support and potential future development. The SSRO's current DefCARS and ITMS contracts are both expiring on 24 March 2026, which provides an opportunity to seek an integrated solution delivered under one contract. We anticipate this will offer value for money based on the potential service benefits and cost savings. The SSRO is intending to seek extensions where necessary to these two contracts to allow for a transition period up to end of August 2026. ITMS The SSRO's ITMS is cloud based and uses the Microsoft stack. Third parties are used for management, support, and development of the IT environment. The SSRO technology and systems estate includes the SSRO Microsoft environment which is based in UK data centres. Connectivity within our office is via Wi-Fi only, provided by the Government Property Agency through the GovWifi service. The GPA also provide a network printing service, GovPrint, connecting to a Xerox printer over GovWifi. DefCARS The SSRO has a contract for the provision of its DefCARS, which is a secure, online system for the capture, storage and analysis of all electronic data reported by defence contractors under the Defence Reform Act 2014. DefCARS is accessed by industry, the MOD and the SSRO. The SSRO intends to hold a virtual Bidders' briefing session on 14 January 2026 via MS Teams at 10am to 11am. Potential Suppliers interested in attending the briefing session must register in advance by contacting the SSRO via the message centre on the Delta eSourcing platform by no later than 12 noon on Monday 12 January 2026. Potential Suppliers should note that this opportunity was previously published on 18 July 2025 (Notice identifier: 2025/S 000-041194). That procurement activity was terminated. The opportunity is being re-published under this tender notice.
