Question 1

What is the UK's digital sovereignty score?

Accepted Answer

As of September 2026 the UK scores an average of 25 out of 100 for digital sovereignty across 11 critical infrastructure sectors, indicating overwhelming dependence on foreign — primarily US — technology.

Question 2

Which UK sector has the lowest sovereignty score?

Accepted Answer

Cloud Infrastructure scores 8 out of 100 — the lowest of any sector — with AI & Frontier Tech at 9. Government, NHS and financial workloads run almost entirely on AWS, Microsoft Azure and Google Cloud, and in June 2026 a US export directive briefly cut every non-US user off from Anthropic's most capable models.

Question 3

How dependent is the UK on US cloud computing?

Accepted Answer

UK cloud infrastructure scores 8 out of 100 for sovereignty. Government, NHS, financial services, and private sector workloads are hosted almost exclusively on AWS, Microsoft Azure, and Google Cloud. There is no UK-origin hyperscaler at commercial scale.

Question 4

Is NHS data stored on US servers?

Accepted Answer

NHS & Healthcare scores 18 out of 100. The NHS Federated Data Platform is built on Palantir and hosted on AWS. Microsoft holds NHS data under US CLOUD Act jurisdiction, meaning the US government could compel access to UK patient records. UnitedHealth Group acquired EMIS (a major GP system) in 2022.

Question 5

What does the UK Digital Sovereignty Monitor measure?

Accepted Answer

It measures how dependent each of 11 UK critical infrastructure sectors is on foreign technology, scoring each from 0 (fully dependent) to 100 (fully sovereign). Components within each sector are tagged as Sovereign, Partial, or Dependent with explanations and sources.
