## Summary

SONI Ltd is seeking one supplier to provide client-side advisory services for its Corporate IT Separation Programme and the establishment of its Security Operations Centre. The work covers programme management and leadership, technical and test assurance, delivery oversight of systems integrators and other suppliers, and transition support. The adviser will augment SONI’s internal programme and technical teams and work alongside them and other external advisers. The role is advisory: it does not include delivering or implementing the underlying systems, equipment or services being procured through SONI’s separate competitions. This is an IT consultancy and assurance service (CPV 72000000), for delivery in the United Kingdom.

SONI invited offers through an open competitive flexible procedure for a single-supplier framework agreement, with a reopening of competition for subsequent contracts. The enquiry deadline was 13 November 2026 at 12:00, and the offer deadline was 20 November 2026 at 12:00. The planned contract period runs from 1 February 2027 to 31 January 2029, with an option, at SONI’s discretion, to extend by one year, to 31 January 2030. The estimated value is £6.3 million excluding VAT (£7.56 million including VAT). Evaluation gives 40% to price and 60% to quality: previous experience (20%), approach and methodology (15%), team capacity (10%) and a face-to-face meeting (15%). The procurement is divided into one lot.

The opportunity suits IT advisory and programme-management firms able to support a complex corporate IT separation and establish a Security Operations Centre alongside the client’s teams. Relevant strengths include programme leadership and governance, technical assurance, test assurance, transition support, and the ability to oversee systems integrators and other suppliers without taking on implementation of the underlying systems. Bidders should be able to demonstrate recent, relevant client-side advisory, programme-management and technical-assurance experience on work of comparable nature and complexity. They will need a credible delivery approach and methodology, plus sufficient qualified and experienced personnel to deliver the work, with clear commitments on key staff time. Small and medium-sized businesses are identified as suitable. A proposed core team will be assessed through a face-to-face meeting as part of the quality evaluation.
