AI CCTV data residency: why UK-hosted matters in 2026

Why this matters more in 2026 than it did in 2024

Three things have shifted the data residency conversation for AI CCTV in the UK over the last 18 months. Government Procurement Policy Note 01/22 narrowed the scope of acceptable vendors in central government and parts of the public sector. ICO guidance on biometric data has tightened. And the political conversation around facial recognition deployments has raised the temperature on data flows generally.

For UK venue operators, particularly those with public-sector adjacencies (universities, healthcare, public-realm venues), the questions to ask vendors are different now from what they were two years ago.

The five questions to ask

1. Where is the data physically stored?

Not where the company is headquartered. Where the actual servers are. UK-hosted means the data is in UK data centres under UK jurisdiction. Some global vendors offer UK regional options. Some do not.

2. Who has access to the data?

Including third-party processors, support staff, and engineering teams. A global vendor with a UK regional option may still have engineers in other jurisdictions with administrative access. That is a different residency picture from UK-only access.

3. What happens to data at the end of the contract?

Deletion timeline, format of any export, and how the deletion is verified. The contract should be explicit. Vague language here is a flag.

4. Is any biometric data processed or stored?

Facial recognition is the obvious case. Voice analysis, gait analysis as biometric identifier, and certain object-classification approaches can also produce biometric data depending on implementation. The cleanest position is a vendor that does no biometric processing at all.

5. Are cross-border transfers occurring?

Even for routine functions like analytics aggregation, support ticket handling, or product telemetry, data may cross borders. The vendor should disclose this and have a documented lawful basis under UK GDPR.

What the ICO has said

The ICO has issued specific guidance on the use of live facial recognition and on biometric data more generally. The direction of travel is increased scrutiny of vendors that store or process biometric data without specific lawful basis. Venues using vendors with biometric processing should expect the ICO question to become more prominent over time.

What Archangel does

UK-built. UK-hosted. No facial recognition. No biometric data stored. The architecture is designed to clear all five of the questions above by default rather than by configuration.
