TSCM Sweeps in London — Discreet Bug Detection by CDEC

Protect Your Privacy from Hidden Listening Devices

London’s corporate, legal and entertainment sectors face an increasing threat from covert surveillance. Conversations held in offices, hotel suites or private homes can be compromised by devices as small as a coin. At Cyber Defence, Evaluation & Consultancy Ltd (CDEC), we provide discreet TSCM sweeps in London to detect and remove hidden microphones, cameras and GPS trackers before they damage your reputation or leak sensitive information. Our counter-surveillance specialists combine law-enforcement-grade equipment with operational experience to deliver total privacy protection for executives, celebrities and high-net-worth clients.

What Is a TSCM Sweep?

A Technical Surveillance Counter-Measures (TSCM) sweep—often called a bug sweep—is a structured inspection of an area to locate and neutralise unauthorised electronic surveillance devices. These may include GSM transmitters, Wi-Fi beacons, Bluetooth trackers or modified electrical fittings designed to record audio and video. Our process ensures that your environment is technically and physically secure, whether you are hosting confidential meetings, managing a sensitive merger, or safeguarding private family life.

How Our Bug Sweeps Work

  1. Threat Assessment: Every assignment begins with a discreet consultation to understand your risk profile, recent security concerns and the nature of the location. We identify potential vulnerabilities and design a tailored sweep strategy appropriate to the threat level.
  2. Physical Search: Our engineers perform a detailed physical inspection of rooms, furnishings and fixtures. Wall sockets, lighting units, mirrors and air vents are checked for tampering or hidden electronics. This hands-on process complements our technical scanning to ensure no area is overlooked..
  3. Electronic Detection: Using advanced RF spectrum analysis, non-linear junction detectors (NLJD), and thermal imaging, we locate both active transmitters and dormant electronic components. Continuous monitoring across radio, GSM, Wi-Fi and BLE frequencies allows us to detect anomalies that traditional sweeps miss.
  4. Signal Monitoring: Describe how signals are identified.
  5. Reporting: Summarise how results are provided to clients.

Frequently Asked Questions

What does a TSCM sweep detect?

A TSCM sweep detects hidden microphones, GSM bugs, Wi-Fi transmitters, Bluetooth trackers, GPS devices and covert cameras. Our London sweeps identify both active and dormant electronic threats across the entire radio frequency spectrum, ensuring no listening or tracking equipment is left behind.

How long does a sweep take?

Most standard offices, apartments or hotel suites require between three and six hours, depending on size and layout. Larger premises or high-risk environments—such as boardrooms or recording studios—can take a full day to complete. We work discreetly and can operate outside normal business hours to minimise disruption.

Do you travel outside London?

Yes. Although we are based in London, we regularly carry out sweeps across the Home Counties and throughout the UK and Europe. We also offer international coverage for clients requiring global continuity of service.

Is my information kept confidential?

Absolutely. Confidentiality is fundamental to every operation we undertake. All data collected during your sweep is securely encrypted, stored on isolated systems, and permanently deleted after project completion unless otherwise agreed in writing.

How much does a TSCM sweep cost?

Every environment and risk profile is unique. Our pricing reflects the area covered, number of rooms, and the level of threat suspected. We provide transparent quotations before work begins, with no hidden fees or add-ons.
