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.
