First time I have used a pi and could not have been more impressed with the service. Very polite and efficient. Hopefully I do not need to use one again in the future but if I do I know where to come.
Technical Surveillance Counter-Measures Explained
A bug sweep, also known as a TSCM inspection, is a structured search for signs of covert monitoring. Concerns may arise after confidential information is leaked, a former partner appears to know private movements, a business negotiation is compromised or an unfamiliar device is found in a room, vehicle or power supply.
No single detector can identify every possible threat. Some devices transmit continuously, others send information intermittently, and some store recordings locally without emitting a radio signal. We therefore combine appropriate technical checks with a careful physical inspection and an assessment of the property, vehicle or working environment.
What We Can Inspect
Subject to the owner’s or authorised occupier’s permission, we can inspect domestic properties, London offices, boardrooms, hotel meeting spaces, serviced offices and vehicles. The scope may include fixtures, power outlets, smoke detectors, furniture, electronic accessories, network equipment and areas where a device could realistically have been placed.
Vehicle sweeps can look for suspicious GPS units, power connections, magnetic housings and other anomalies. We only inspect vehicles where the client can demonstrate lawful authority. We do not force entry, damage property or search premises controlled by another person without appropriate consent.
Areas We Cover
SPS Investigations provides discreet, professional private investigation services across London, the Home Counties and selected commuter towns within reach of the capital.
Whether you need help with a sensitive personal matter, a relationship concern, people tracing, surveillance, corporate investigation or process serving, our team can advise you confidentially and explain the most appropriate next steps. If you are unsure whether we can help in your area, contact us for a confidential discussion.
How a London Bug Sweep Is Carried Out
We begin with a confidential risk assessment covering who may have had access, what information appears compromised, when the concern began and whether any suspicious events have occurred. This helps us prioritise the areas and frequencies most relevant to the assignment instead of carrying out a superficial scan.
The inspection may include radio-frequency analysis, non-linear junction detection where appropriate, checks for hidden optical devices, physical examination and review of authorised network or wireless equipment. Because London buildings can contain dense radio traffic from neighbouring flats, offices and public networks, readings must be interpreted carefully rather than treated as automatic proof of a bug.
Findings, Removal and Ongoing Protection
We explain any suspicious findings and can document the location, condition and apparent function of a device. Depending on the circumstances, it may be safer to preserve the item, involve a solicitor or contact the police rather than immediately remove or activate it. We will not interfere with equipment where doing so may create risk or compromise potential evidence.
We can also recommend practical improvements such as access control, meeting-room procedures, device inventories and periodic re-inspection. We do not use signal jammers. Operational jamming is generally unlawful in the UK, and a professional sweep should identify and manage risks without disrupting legitimate communications.

Frequently Asked Questions
A bug sweep is a technical and physical inspection for covert surveillance equipment, such as listening devices, hidden cameras, unauthorised GPS trackers and suspicious electronic components. It is often described as technical surveillance counter-measures or TSCM.
No company can honestly guarantee detection of every device. Some bugs transmit, some record locally and some remain dormant. A thorough inspection uses several methods and considers physical access, device behaviour and the environment.
Potentially, provided the person instructing us has proper authority over the premises and the work is lawful and proportionate. Employment, privacy and data protection issues should be considered before any covert workplace activity.
Yes, where you can show lawful authority over the vehicle. We can inspect likely mounting points, power connections and suspicious devices, but we will not search or interfere with a vehicle controlled by someone else without permission.
Not automatically. The safest response depends on ownership, risk and whether the device may be evidence of a criminal or civil matter. We can document the finding and discuss whether it should be preserved, removed by an authorised person or reported to the police.
They can include checks of authorised wireless and network equipment where this is within scope and access has been approved. A network review is not a substitute for broader cyber-security work, and we do not access systems without permission.
No. The operational use of jamming equipment is generally unlawful in the UK. We use detection and inspection methods that do not intentionally disrupt lawful radio services.
The time depends on the size and complexity of the premises or vehicle, the level of risk and the number of rooms or systems included. We define the inspection area before attendance and explain any preparation required.

Great service, Patrick turned around exactly what I needed super quick, very friendly and informative. Very please with the work! Highly recommend.
I reached out to Patrick over 24 hours ago, and he promptly provided all the information I needed. His service was fast, efficient, and affordable. After contacting several local private investigators, none gave me the personable impression that Patrick did. I wholeheartedly recommend his services – thank you so much!
Good morning, just want to say thank you for last night and appreciate all your efforts In finding me some clarity. From the start to finish everything you delivered was perfect and professional. Thank you again.
I was initially hesitant about hiring a private investigation company in London, but my experience with SPS Investigations completely changed my perspective. From the very beginning, their professionalism and dedication stood out. Patrick’s team displayed exceptional expertise in handling my case, providing regular updates and ensuring I was informed every step of the way. Their attention to detail was truly impressive, and they went above and beyond to gather the necessary information. The results they delivered were beyond my expectations, and their discreet approach gave me the peace of mind I needed. I can confidently say that SPS is an exceptional investigation agency, and I would highly recommend their services to anyone seeking reliable and trustworthy assistance.
Great value for money, arrived early on survellience ultra discrete at 7.45am until 9am in London in early May 2022 and went back the same day early afternoon. Very good live tracking with photos to my phone. Worth every penny. I needed to extend the survellience and they agreed quickly no fuss and no obsorbatant charges, the same rate added. Even though it went upto midnight the additional charge was very reasonable. Will use them in the future a great find as Iooked at so many others who were sharks and unreasonable, so very grateful to have found them. This was all last minute and arranged outside normal working hours because Shaun is available 7×24 managing all my requirements quickly and efficiently as I was traveling most of the time.
Thank you so very much
The Service was as promised. We got the results, that we were after. A very Professional & Dillgent company to work with. Definitely Recommend.
I was a bit sceptical about using a Private Investigator due to the expense of it all but SPS Investigators were very efficient and guided me the whole way. I couldn’t have asked for a better service. The evidence they managed to obtain was just want I needed for closure on an unhealthy relationship. Thank you!
Patrick once told me if I were you I’d stop surveillance on this guy and never talk to him again. He said he doesn’t want to take more money from me, which is very noble of him.
Thank you for your help on everything, it’s much appreciated.
