The UK government and its regulators are steadily expanding state surveillance over private, encrypted communications. This has come primarily through secret Technical Capability Notices issued under the Investigatory Powers Act 2016 — the law widely known as the “Snoopers’ Charter” — which can compel technology companies to build and maintain the capability for the government to access their users’ communications, and which by default prohibit companies from disclosing that they received such a notice. Proponents of these powers have suggested that they are necessary to investigate serious crime and that they enjoy broad public support.
To assess the public’s attitudes, CDT commissioned Public First, a UK-based polling firm, to survey British public opinion on encryption and government surveillance. The results tell a compelling story. Across the board, the polling data consistently and often overwhelmingly demonstrate public pushback against expanding surveillance frameworks that threaten to infringe upon encrypted communications. Far from reflecting a public appetite for secretive monitoring, the results suggest that the British public have deep reservations about state access to their private conversations. Most critically:
- The British public overwhelmingly believe they have the right to private conversations online and that no one should be able to access their personal messages without a court order and user notice.
- The majority of the British public oppose or want meaningful constraints on surveillance powers like Technical Capability Notices.
- The majority of the British public believe the security risks outweigh the benefits of allowing law enforcement to access encrypted messages.
- Overwhelming majorities of the British public are concerned that allowing law enforcement to access encrypted messages could discourage free speech or open communication or undermine personal privacy.
- Many of the British public will change how they express themselves online if law enforcement has access to their encrypted messages, such as by self-censoring or deleting their social media accounts.
The vast majority of the British public believe there are better ways to tackle serious crimes than accessing encrypted messages.

Executive Summary
Full Take
The narrative constructs a tension between state security imperatives and fundamental individual rights to privacy and free expression within digital spaces. The presented statistics suggest that the stated necessity for law enforcement access to encrypted data is not universally accepted by the public; rather, there is a strong consensus regarding the inherent value of private online communication. This reveals a potential misalignment between policy justification and public perception regarding surveillance technology.
The implication is that attempts to justify expanded surveillance by appealing solely to crime investigation metrics are likely to face significant resistance if they disregard established principles of digital autonomy. The concern expressed—that access might lead to self-censorship or the erosion of free speech—points toward a potential chilling effect on communicative behavior, suggesting that the cost of surveillance may be a devaluation of open discourse itself.
The pattern observed is one where abstract security goals are framed using legal mechanisms (like the Investigatory Powers Act) that create an asymmetry between state power and individual expectation. The public's rejection suggests a failure in framing: if access is viewed as inherently intrusive rather than purely conditional, acceptance becomes less likely. Further inquiry should focus on whether alternative, privacy-preserving investigative techniques can effectively address criminal matters without infringing upon the fundamental right to encrypted communication and free expression. What tangible mechanisms exist for ensuring that state powers are strictly limited to necessity and proportionality, rather than being expanded by default?
