Private information appears outside the room
Details from strategy, pricing, legal, personnel or negotiation discussions become known to people who were not expected to have them.

Signs Your London Office May Be Bugged
Information leaks, unexplained knowledge of private discussions or suspicious changes to equipment can justify investigation—but none proves that an office is bugged. This guide explains what deserves attention and what to do next.
Start With Evidence
What usually causes a business to consider a sweep?
Most corporate enquiries begin with an information-security concern rather than the discovery of a device. A competitor may appear unusually well informed, details from a closed meeting may circulate unexpectedly, or an unfamiliar item or modification may be noticed in a sensitive area. These observations justify calm investigation, not an assumption that surveillance is present.
02
Unexplained equipment or changes
New chargers, adapters, clocks, conferencing accessories, cabling or altered fittings appear in or near a sensitive room without a clear owner or purpose.
03
Unusual access before key discussions
Contractors, visitors or equipment have had unsupervised access to a boardroom, executive office or meeting space before confidential activity.
Avoid False Alarms
Common observations that are not proof of a bug
Interference on a phone, battery drain, clicks on calls, Wi-Fi activity and unfamiliar radio signals all have many legitimate causes. Modern offices contain dense wireless environments, including access points, mobile phones, Bluetooth peripherals, conferencing systems, access control and building-management equipment.
Detection is not identification
A basic RF detector can indicate radio energy, but it cannot by itself establish that the source is a listening device. Professional TSCM investigates signals and physical anomalies in context.
What To Do
If you have a genuine concern
Keep the concern on a need-to-know basis, avoid repeatedly handling or dismantling a suspicious object, and record what prompted the concern. If a sensitive meeting is imminent, consider moving the discussion or arranging a pre-meeting inspection rather than attempting an improvised search.
- Define the sensitive areas — boardrooms, executive offices and rooms where the relevant information was discussed.
- Preserve context — do not remove every electronic device before the inspection; legitimate equipment helps establish the normal environment.
- Review access — consider staff, visitors, cleaners, contractors and equipment introduced into the area.
- Use a proportionate TSCM scope — RF analysis, physical/electronic inspection and other methods should reflect the concern.
