Put data behind every decision

Butterfly Data's principal IT consultant, Henry Newman-Burke, and data scientist, Maja Strawinska will be presenting at the Public Sector Connect Data and AI Summit 2026, sharing expert insight on governing data migration across large-scale public sector programmes.

No surprises on moving day: Governing data migration at scale

In their session, “No surprises on moving day: Governing data migration at scale,” Henry and Maja use the familiar analogy of moving house to explore how organisations can successfully manage complex data migrations - particularly when upgrading to smarter, AI-enabled platforms.

Just like a house move, successful migration requires:

• Clear planning and decision-making
• Knowing what data to keep and what to retire
• Accurate labelling through strong metadata and classification
• Solid foundations for future AI capabilities
• Robust governance to prevent disruption

For public sector organisations modernising legacy systems, the risks of poor migration are significant, from compliance issues to service disruption. Strong governance ensures data is not only moved safely, but structured and prepared to power the next generation of digital services.

Supporting AI-ready public services

Together, Henry and Maja will highlight how governance-led data migration reduces risk, protects compliance and enables trustworthy AI adoption across government.

The Public Sector Connect Data and AI Summit 2026 brings together leaders shaping the future of public services. Butterfly Data’s session will provide practical insight for those planning cloud transitions, system upgrades or AI implementation to ensure there are truly no surprises on moving day.

Butterfly Data has been awarded a place on the Government Commercial Agency's (GCA) G-Cloud 15 framework as part of Lot 3 (Cloud Support), giving public sector buyers a compliant route to procure our data strategy, cloud migration, integration and analytics services through the Digital Marketplace.

G-Cloud 15 is the UK government's flagship cloud procurement framework, expected to facilitate billions of pounds in public sector cloud and data spend over its term. Butterfly Data’s inclusion on the framework means public bodies across central government, local government, policing and health can now call off its full range of 16 services.

Which Butterfly Data services will be available via the G-Cloud 15 framework?

The data services available on the G-Cloud 15 framework span the entire data lifecycle, including data maturity assessment, governance, cloud migration, platform engineering, integration, and advanced analytics and AI.

Among the broad offerings are also specialist services such as SAS Law Enforcement Intelligence (LEI) for Policing, which aims to help police forces turn disparate intelligence data into actionable, governed insight.

Butterfly Data’s services can be grouped into four main areas: data foundations (maturity assessment, governance, and privacy); cloud and platform engineering (migration, architecture, Snowflake, and SAS); integration and quality (Informatica, data quality and modernisation); and analytics and AI (visualisation, data science and SAS LEI).‍

Why does Butterfly Data stand out among G-Cloud 15 Lot 3 suppliers?

Public sector buyers evaluating Lot 3 suppliers tend to weigh three things: can this supplier be trusted with sensitive data, can they deliver without the overhead of a large prime and can they prove it. We believe we answer all three.

1. Trust, built to last. Handling citizen or national security data isn't something to take on faith — Butterfly Data holds security clearance as standard. That sits alongside B-Corp certification, employee ownership and more than 20 years industry experience.‍
2. Prime-level capability, without prime-level overhead. Large prime contractors bring scale, but also cost and process that many departments are actively trying to move away from. Butterfly Data is built to be leaner and faster to mobilise, which is exactly the alternative departments are asking for when they talk about reducing reliance on a small pool of large suppliers.
3. ‍A delivery record you can check. Our case studies set out what we've actually delivered in government and the wider public sector.

‍Public sector buyers will find links to each of our service listings here once the Digital Marketplace listing goes live – check back soon, or get in touch directly in the meantime.

Butterfly Data has become a member of the UK’s leading tech industry trade body, techUK.

techUK represents over 1,000 organisations, from global brands to specialist consultancies, working to shape how technology serves the UK, including its public sector digital transformation agenda. That is the same space we play in every day – helping government departments turn messy, siloed data into something they can actually trust and build on.

The membership gives us a seat at that bigger table. We will be actively participating in techUK’s working groups and policy discussions around data, AI and public sector technology, including sharing what we are seeing on the ground with clients like HMRC, DWP and the Home Office and bringing back the insights and connections that help us do better work for them.

“Joining techUK gives us a stronger voice in conversations that matter to our clients," said Rob Norrish, Sales Director. “Public sector organisations are under real pressure to modernise, and being part of a community that is actively shaping policy and practice around data and AI means we can take sharper thinking back to the departments we work with.”

We are looking forward to getting stuck into techUK’s events and programmes over the coming months and, in the longer term, being part of a community that is pushing for the same thing we are: technology that actually works for the people who depend on it.
