The British Business Bank is seeking to partner with expert engineering suppliers through a high-value multi-supplier Engineering Framework. With an estimated contract value of £14,760,000 including VAT and a four-year term (September 2026 – August 2030), this framework will supply digital, software, AI, and platform engineering services to one of the UK's most prominent government-owned financial institutions. For specialist digital and engineering firms with experience in regulated, data-driven environments, this is a compelling route to sustained public sector work.

Framework Structure: Six Lots Covering the Full Digital Engineering Stack
This is a Planned Procurement Notice. The formal tender has not yet been published, but the Bank is signalling its intention to market. The framework is expected to be structured across six specialist lots:
- Lot 1: Software Engineering and Application Design
- Lot 2: Artificial Intelligence (AI) — AI, Automation, and Intelligent Systems Design
- Lot 3: Service Design
- Lot 4: Platform Engineering (DevOps)
- Lot 5: Product Design / User Interface
- Lot 6: Digital Services Web Product Development
This six-lot structure is significant for suppliers: rather than competing as a generalist digital agency, you can position for the one or two lots where your capability is genuinely strongest and most evidenced. The inclusion of a dedicated AI lot (Lot 2) reflects the Bank's digital ambitions and will be a competitive but valuable area for firms with demonstrable AI delivery in complex, regulated settings. Thornton & Lowe has supported technology businesses bidding for digital framework agreements across the UK public sector; see our bid writing guide for more on how these processes typically unfold.
Why the British Business Bank Engineering Framework Matters
The British Business Bank occupies a unique position in the UK financial landscape. It is a government-owned development bank tasked with making finance markets work better for smaller businesses. Its digital portfolio underpins everything from scheme administration to data infrastructure, and the Engineering Framework will supply the technical expertise needed to maintain and evolve that portfolio. Successful suppliers will have opportunities to work on software engineering, AI delivery, DevOps, service design, and web product development: all critical elements in modernising a public financial institution's digital capabilities.
A four-year term means genuine pipeline depth. Call-off contracts across the life of the framework give suppliers a stable revenue stream rather than one-off project work. Demonstrating that you can build long-term delivery partnerships, not just deliver sprints, will strengthen your submission.

Bidding Considerations & Strategic Advice
- Lot selection: Identify the one or two lots most aligned to your core delivery capability and begin building targeted evidence and case studies now, before the ITT is published.
- Regulated sector experience: The British Business Bank operates in a financially regulated environment with significant data governance obligations. Demonstrable experience in similarly regulated sectors (financial services, public sector, health) will differentiate your bid.
- Lasting relationships: A four-year term rewards suppliers who can demonstrate consistent capacity, scalable teams, and a track record of long-term partnership rather than transactional delivery.
- AI capability: If bidding for Lot 2, be specific about your AI delivery methodology, governance approach, and how you ensure responsible and explainable AI in sensitive or regulated contexts.
Spend time analysing the framework notice and watch for the formal ITT publication in June 2026. Early engagement means you can assemble the right team and craft a compelling, compliant submission from a position of strength.
