For twenty years, digital transformation across government has made genuine progress, from the consolidation of GOV.UK and central digital functions to trusted national identity infrastructure. Yet, these gains remain uneven, leaving islands of delivery excellence surrounded by legacy systems, disconnected workflows, and short-term funding constraints.

Every government aims to transform the state, reaching for new departments, units, and strategies. However, after ten years of building digital services across central government and the NHS, Hippo’s view is clear: the hardest part of transformation is not the strategy or the technology, but delivery. It comes down to whether data can move safely, funding spans beyond a single year, the public trusts what is built, and teams have the clear accountability and authority to decide.

This paper sets out what we have learned from working directly between policy ambition and live services. Written for both civil servants delivering services and policy teams shaping what comes next, it offers practical insights into where to push first to unlock lasting, long-term change.
