TSCM Bug Sweeping & Technical Counter-Surveillance

If private conversations or information seem to be known by someone who should not have them, you may worry that a listening device, hidden camera or tracker has been placed in your home, office or vehicle. TSCM is the professional term for a bug sweep. Our bug sweeping TSCM in London is a structured inspection for hidden surveillance equipment and related security weaknesses.

Many inspections do not find a hidden device. That does not mean your concern is being dismissed. A sweep may identify ordinary equipment, technical interference or security weaknesses that offer a more likely explanation and help you reduce future risk.

When people request a bug sweep

Private information appears to be known outside the intended group.

An unfamiliar device, cable, charger, alarm part or vehicle item has been found.

Someone untrusted has had access to a home, office, meeting room or vehicle.

A confidential meeting, business deal or dispute requires an extra security check.

There is a concern about a possible tracker, hidden camera or listening device.

We begin by understanding the concern

Before arranging a visit, we ask what happened, who had access, which rooms or vehicles are involved and whether there is any immediate danger. This helps us decide whether a physical bug sweep is the right service or whether the problem is more likely to need IT support, a phone examination, electrical repair or police advice.

What happens during a sweep

The inspection is tailored to the location and concern. It may include a careful physical search and suitable electronic checks for signals, cameras, trackers and unusual devices. We agree which rooms, vehicles and equipment are included before the work begins.

We do not damage furniture, fittings or equipment. If something needs to be opened or moved, we first confirm that you have the authority to allow it.

Homes and residential properties

A residential sweep can cover the agreed rooms and relevant equipment. Homes contain many normal wireless and electronic devices, so unusual signals do not automatically mean that a bug is present. We investigate and explain them rather than creating alarm.

Offices and meeting rooms

Commercial premises can contain complex phone, network, security and meeting equipment. The visit should be arranged when the area can be controlled and the equipment can be checked properly. We can also suggest simple improvements for future confidential meetings.

Vehicle inspections

A vehicle sweep needs legal access, a suitable inspection location and enough time to examine the relevant areas safely. If a possible tracker is found, do not immediately destroy it or confront someone. The police, a solicitor or another adviser may need to consider safety and evidence first.

If we find something

We record and explain the item before deciding what should happen to it. Finding a device does not automatically prove who placed it. Removal, police contact or further examination may need to be agreed separately.

If we do not find a device

A sweep can only cover the places and time agreed. It cannot prove that no device has ever existed or that information is not being shared in another way. Your report explains exactly what was checked, what was found and what sensible steps you can take next.

Phones, computers and spyware

A physical bug sweep is not the same as examining a phone, computer or online account. If you suspect spyware, stolen passwords or deleted files, a qualified digital specialist may be needed. We can help arrange the correct service.

Pricing

Vehicle bug sweeps start from £450 + VAT. Residential sweeps start from £750 + VAT. Commercial sweeps start from £1,250 + VAT. Size, number of rooms, equipment, travel and urgency affect the final price.

Most Popular Questions

Frequently Asked Questions

Can you guarantee that there are no hidden devices?

No provider can give an unlimited guarantee. We report what was checked and found at the time of the inspection.

Should I remove a device I find?

Ask for advice first. Removing it may create safety or evidence problems.

Will anyone know that a sweep took place?

The visit can be arranged discreetly. At a business, a small number of authorised people may need to help with access.

Can you check my phone for spyware?

That normally requires a separate digital examination rather than a physical bug sweep.

How long does it take?

It depends on the size, amount of equipment and concern. We estimate the time after understanding the property or vehicle.
