UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

Karbon Homes procured integration platform services for its housing and related applications. The requirement is for middleware and an integration platform that can connect mainly cloud-based systems, manage application programming interfaces, and automate business processes. The service also covers software integration consultancy, system and support services, and other software-related services. The work supports Karbon Homes’ wider business transformation programme and replacement of its core information and communications technology infrastructure. Delivery is across the United Kingdom, with the procurement associated with housing services. The requirement was designated as Lot 6, Integration platform. Karbon Homes is the buying organisation, and the service is intended to provide the integration layer and technical dependency for other parts of its systems transition.

The procurement is complete and has been awarded by direct award to Salesforce UK Limited. The award is pending, with a scheduled contract signature milestone on 4 August 2026. The award value is £803,500.20 excluding VAT, or £964,200.24 including VAT. The awarded contract period is 14 August 2026 to 14 August 2031. The related lot shows a separate period from 1 July 2029 to 30 June 2034, with a maximum extent to 30 June 2038, and renewal is permitted. The buyer used a direct award after market testing concluded that no reasonable alternative or substitute met the core technical criteria. It also cited technical dependency, operational risk and the lack of a suitable existing framework route. Additional Mule Credits may be purchased to accommodate increased data transfers.

This opportunity demonstrates demand from a housing provider for enterprise integration capability linking cloud applications, managing APIs and automating business processes. A credible future supplier would need strong expertise in middleware and software integration, including designing, implementing and supporting connections between housing and related corporate systems. Experience with integration platforms, API management, data-transfer capacity and business-process automation would be relevant, alongside the ability to support a complex, multi-system transformation. Suppliers should be able to manage technical dependencies and continuity risks while integrating with an organisation’s core information and communications technology infrastructure. The selected provider’s scale and specialist software capability indicate that competitors would need substantial technical depth, dependable support arrangements and capacity to handle changing data volumes.

Procurement Information

As part of an extensive business transformation initiative to replace its Core ICT infrastructure, Karbon conducted a robust market testing exercise. A Preliminary Market Engagement Notice was formally published to evaluate potential solutions and delivery partners. This exercise examined several service providers across eight distinct requirements and technical lots. Following an evaluation of the market responses, Karbon is making a direct contract award to Salesforce for its core Integration requirements. The preliminary market engagement demonstrated that, no reasonable alternative or substitute exists that could satisfy the core technical criteria of this lot. While Karbon initially intended to utilise an established framework for this procurement, the specific commercial model required to minimise public expenditure and optimize value for money was technically and commercially unavailable through any existing framework route. Securing Salesforce for the integration requirements serves as a technical dependency and enabler for the remaining seven lots. By securing the integration layer first, Karbon can legally and safely award the remaining seven lots via competitive procedures, such as further competition or established frameworks. The duration of this direct award is strictly limited to the minimum period necessary to execute the wider system transition. Bypassing an immediate competition for this specific integration layer is a proportionate measure. A competition at this stage would introduce disproportionate costs, extreme technical complexity, and unacceptable operational risk to the continuity of Karbon's critical corporate services.
