## Key points

- Claude access becomes default for UK Copilot tenants on 9 December.
- Administrators can disable access before the change takes effect.
- Anthropic processes the relevant data in the United States.

## Summary

Microsoft will enable access to Anthropic’s Claude models by default for UK Copilot tenants from 9 December. The change means organisations must review their settings if they do not want Claude available, particularly where US-based data processing may affect compliance requirements.

Anthropic acts as a Microsoft subprocessor, and its documentation says relevant data is processed in the United States. Claude is already enabled by default for most commercial cloud customers, while the UK, European Union and European Free Trade Association have been exceptions. Microsoft says it is also retiring a setting that limited Claude access to Microsoft 365 alone.
