Questions Clients Ask Before a Sweep

Our service is focused on technical surveillance detection. We analyse signals and electronic systems rather than simply reacting to every RF indication as if it were a bug.

Frequently Asked Questions

Professional Bug Sweeping & TSCM

Choose a question below. If your situation is unusual or sensitive, you can contact us directly without describing everything in an initial message.

What is a professional TSCM bug sweep?

A professional TSCM inspection is a structured technical search for covert surveillance devices and suspicious electronic activity. Depending on the location and threat, it can combine RF spectrum analysis, signal investigation, physical inspection, wireless/network checks, hidden-camera examination and other appropriate techniques. It is not simply a walk-through with a handheld RF detector.

How is Bug Detectors UK different from a private investigator?

Bug Detectors UK is an engineering-led TSCM service. Our background is in RF and electronics engineering and the design and analysis of surveillance technology. We focus on the technical investigation of signals, devices and electronic systems rather than general private-investigation work.

What types of premises can you inspect?

We provide TSCM and bug-sweeping services for homes, flats, offices, boardrooms, meeting rooms, executive areas and other sensitive locations. We also provide vehicle bug and tracker inspections. London, the Midlands and other UK locations can be covered by arrangement.

What can a bug sweep look for?

Depending on the assignment, an inspection may consider covert RF transmitters, cellular devices, Wi-Fi or Bluetooth surveillance, hidden cameras, GPS or other tracking devices, recorders, suspicious wiring or electronics, and devices that transmit only intermittently. No single detector can identify every possible surveillance method.

Can you detect a bug that is not transmitting?

Potentially, but not by RF monitoring alone. A device may be dormant, recording locally or transmitting only occasionally. This is why a professional investigation can also include physical inspection and other electronic detection techniques where appropriate.

Read our guide to non-transmitting devices

Can you find hidden cameras?

Yes. Hidden-camera detection can form part of a TSCM inspection or be requested as a specific service. Cameras may communicate over Wi-Fi or other radio systems, or may record locally without transmitting, so the search should not rely on RF detection alone.

Do you inspect vehicles for GPS trackers and listening devices?

Yes. Vehicle inspections can investigate suspicious tracking, listening or other electronic surveillance devices while distinguishing them from the legitimate electronics already fitted to modern vehicles. Workshop prices start from £495 for older or simpler vehicles, £695 for modern connected vehicles and £895 for newer or highly connected vehicles. Age is a guide only; the make, model and fitted systems determine the final tier. Mobile attendance is also available with a travel/call-out charge from Northampton.

How much does a professional bug sweep cost?

Pricing depends on the property or vehicle, size, location, complexity and the scope of the inspection. We publish starting prices so clients have a realistic indication before contacting us. A quotation is confirmed once we understand the location and requirement.

How long does a TSCM inspection take?

The time required depends on the size and complexity of the location, the number of rooms or vehicles involved and anything identified during the inspection. A small targeted assessment may take considerably less time than a full residential or corporate survey. We will discuss the likely scope before attendance.

What should I do before a bug sweep?

Avoid making major changes to the area simply because you suspect surveillance. If possible, leave suspicious items in place and make a note of anything that caused concern. You do not need to send sensitive details in an initial message; basic location and contact information is enough for us to start a confidential discussion.

What happens if you find something suspicious?

We first establish what the item or signal actually is rather than assuming that unfamiliar electronics are surveillance devices. Where further examination is appropriate, suspicious equipment can be documented and may be taken to our RF/electronics workshop for additional technical analysis with the client's agreement.

Will I receive a report?

The level of reporting can be agreed for the assignment. Findings can be explained at the end of the inspection and, where required, documented in a written technical report with relevant observations and recommendations.

Is my enquiry confidential?

Yes. TSCM enquiries are handled discreetly. For an initial WhatsApp, telephone or contact-form enquiry, only basic details are needed. More sensitive information can be discussed directly once contact has been established.

Do you provide bug sweeping in London?

Yes. We provide London TSCM and bug-sweeping services for private and corporate clients, including homes, offices, boardrooms and vehicles. See our dedicated London page for the service overview.

Can a cheap RF bug detector replace a professional sweep?

No. A basic RF detector can indicate the presence of radio-frequency energy, but homes, offices and vehicles contain many legitimate transmitters. Professional TSCM is concerned with analysing and interpreting signals and combining RF investigation with other inspection methods rather than treating every RF indication as evidence of a bug.
