Bespoke Private Investigations & Surveillance Services
Privat Security provides bespoke private investigation and surveillance services for individuals in London and throughout the UK who need clarity, legally and ethically obtained admissible evidence along with professional advice in handling sensitive personal matters.
​
Whether you are concerned about a relationship, harassment, personal safety, a missing person, or the background of someone entering your life, our role is to establish the facts quietly, lawfully and without unnecessary exposure.
​
Our experienced Association of British Investigators (ABI) accredited private investigators are experienced professionals from specialist backgrounds including UK Special Forces, military intelligence and specialist police units. This allows us to handle complex and sensitive situations effectively and efficiently with absolute discretion and confidentiality while delivering clear, irrefutable evidence you can act on.
We understand that most clients come to us during uncertain or difficult moments. Our approach is therefore not only strategic, but also measured, discreet, confidential, and tailored entirely to you and your situation. Every enquiry is handled in strict confidence.


Private Investigation Services for Sensitive Personal Matters
We support private clients across London, the UK and globally with highly confidential and complex investigations, including:
​
-
Address tracing & location assessment reports
-
Vehicle tracking
-
Evidence gathering for legal or family proceedings
-
Witness statements and court attendance
-
Process serving
​
Every investigation is tailored to the specific circumstances of the case. We do not apply generic methods or prolong enquiries unnecessarily. Instead, each operation is built around a clearly defined investigative strategy designed to establish the facts as efficiently, discreetly and cost-effectively as possible, whilst maintaining the highest standards of professionalism and confidentiality.
Covert Surveillance
Our covert surveillance services are designed to operate discreetly, gather evidence ethically and lawfully while establishing a clear understanding of facts before any action is taken. We help clients confirm what is happening, who is involved, where someone is going, and whether their behaviour is consistent with what they have said.
​
This includes photographic and video evidence, detailed written reports and documented timelines of activity. Every surveillance operation is bespoke and carefully planned around the specific circumstances of the case, the legal considerations involved and the level of discretion required.
​
For our clients, covert surveillance is commonly used in matters involving suspected infidelity, relationship concerns, harassment, safeguarding issues, disputes, or situations where an individual’s behaviour or movements need to be verified.
​
The aim is not simply to follow someone, but to obtain credible, professionally gathered evidence in the most cost-effective way that provides clarity and allows you to make informed decisions with confidence.
Marital Infidelity and Relationship Investigations
Concerns about a partner or spouse can be very difficult, particularly when you are relying on instinct, conflicting explanations or incomplete information.
​
Concerns surrounding a partner or spouse can be difficult, particularly when their behaviour changes unexpectedly, explanations seem to contradict or important details appear intentionally concealed.
We provide discreet relationship and infidelity investigations for individuals seeking clarity before making important personal, financial or legal decisions. These investigations are often initiated where there are concerns surrounding dishonesty, unexplained absences, secretive behaviour, unknown associates, or inconsistencies in a partner’s movements, activities or online behaviour.
​
Our investigators can conduct covert surveillance, verify movements and locations, analyse behavioural patterns and compile professionally documented, legally admissible evidential reports supported by photographic and video evidence.
​
Our team can also utilise lawful digital and open-source intelligence (OSINT) techniques, including online behavioural analysis and digital footprint analysis, to establish online activity, identify behavioural patterns and support wider investigative findings
​
Every investigation is carefully planned around the specific circumstances of the case and the legal considerations involved. Our objective is never simply to follow an individual, but to establish the facts accurately, discreetly and efficiently without unnecessarily escalating the situation or exposing the investigation.
​
All enquiries and investigations are handled with sensitivity, professionalism and absolute confidentiality. Our role is to provide facts, not judgement and give you the clarity to know where you stand.
Stalking and Harassment Investigations
If you are experiencing stalking, harassment, unwanted attention or intimidation, it is important that the situation is handled professionally, documented ethically and legally, without placing yourself or those around you at further risk.
​
We provide discreet stalking and harassment investigations designed to gather evidence lawfully, identify behavioural patterns and support the preparation of professionally documented admissible evidential files for police reports, legal proceedings or protective action.
​
Depending on the circumstances of the case, investigations may involve covert surveillance, incident logging, witness enquiries, and again digital evidence review and lawful digital and open-source intelligence techniques to identify relevant activity, associations and patterns of behaviour.
​
Your safety, privacy and reassurance remain the priority throughout. By attempting to obtain evidence yourself, through a friend or family member, you can unintentionally escalate matters, compromise safety or undermine potential legal proceedings. Our role is to manage the investigation discreetly and professionally whilst helping protect your privacy and wellbeing throughout.
​
Where there are genuine concerns surrounding personal or family safety, we can also provide bespoke Close Protection Operatives, commonly known as bodyguards and Residential Security to support your safety whilst investigations are ongoing and evidence is being obtained lawfully.
Missing Persons and Trace Enquiries
Locating a missing, estranged or hard-to-find individual often requires far more than a basic address trace. In many cases, individuals intentionally limit their visibility, change routines, minimise their digital footprint or actively avoid contact, requiring a structured and intelligence-led investigative approach.
​
We assist private individuals and families in locating missing persons, estranged relatives, debtors, witnesses and individuals connected to personal or legal matters.
​
This may include current address tracing, welfare-related enquiries (confirming an individual’s wellbeing) and current circumstances, identifying known associates, verifying frequented locations and establishing the whereabouts of an individual who has become difficult to contact.
​
Our investigators utilise a combination of intelligence-led research, lawful digital and open-source intelligence techniques, behavioural analysis, discreet enquiries and on-the-ground investigative and surveillance methods to develop accurate and actionable findings, verify information, establish patterns and determine an individual’s whereabouts.
​
Every missing person and trace enquiry is handled with sensitivity, professionalism and absolute discretion, our team deeply recognises the personal, legal and emotional complexities that are often involved in these cases.
Background Checks and Personal Due Diligence
Before placing trust in an individual, it is often important to properly understand their background, credibility and any potential risk factors.
​
Our background checks and personal due diligence investigations help private clients make informed decisions regarding individuals entering their personal, family or domestic environment particularly where children, vulnerable individuals or significant personal access may be involved.
​
This may include enquiries relating to new partners, new friends or associates, private staff, tenants, carers, household employees or individuals involved in sensitive personal or financial arrangements.
​
Our investigators can conduct identity verification, intelligence-led enquiries, use digital and open-source intelligence techniques, reputation and association analysis, and behavioural assessments to identify inconsistencies, undisclosed concerns or potential risk indicators. Along with checks relating to criminal history, previous convictions, adverse financial issues, employment background, directorship history, and publicly available records where legally permissible.
​
Where appropriate, our investigators can conduct identity verification, background research, lawful digital and open-source intelligence enquiries, reputation analysis and behavioural assessments to identify inconsistencies, undisclosed concerns or potential risk indicators.
We help verify identity, credibility, reputation, history and any potential risk indicators, giving you the information to make informed decisions with greater confidence on who to let into your life and around your family.
Counter-Surveillance and Privacy Protection
For high-profile individuals, executives, public figures or private clients with elevated privacy concerns, we provide counter-surveillance designed to establish whether you are being watched, followed or monitored unlawfully.
​
If you suspect your movements, communications, devices or private environments or someone you are associated with may have been compromised, it is important that the situation is handled quickly, discreetly and professionally.
​
Depending on the circumstances involved, our investigators can conduct surveillance detection techniques, behavioural and movement analysis, route monitoring to identify unwanted attention, suspicious activity and establish whether surveillance is taking place on you, your family or associates.
​
Where confidentiality is critical, we can also carry out Technical Surveillance Counter Measures (TSCM), commonly referred to as bug sweeps, across private residences, hotels, offices, vehicles, aircraft, yachts and other sensitive environments ensuring that no unauthorised listening (audio or video) or tracking devices are present.
​
This can also include the inspection and assessment of personal devices such as mobile phones, tablets, laptops and other electronic equipment to identify unauthorised listening, monitoring, tracking and privacy concerns.
​
Where risks or vulnerabilities are identified, we can provide risk management guidance and protective solutions (both physically and digitally) designed to help restore your privacy, reduce exposure to risk and protect both your personal and professional environments.
Evidence & Reporting
The quality of any investigation naturally depends on the quality of the evidence.
​
While the effectiveness of any investigation depends not only on the information obtained and how it was obtained, but also on how that information is documented, verified and presented so it’s legally admissible in court.
​
At Privat Security, all evidence by our team of investigators is gathered lawfully, ethically and professionally with careful consideration for discretion, evidential integrity and potential legal use. Our investigators maintain detailed operational records throughout the course of an investigation, ensuring that findings are accurately documented and supported wherever possible.
​
We provide precise, structured legally admissible reporting designed to be clearly understood and acted upon. We are able to provide evidence including:
​
-
Time-stamped written reports
-
Photographic evidence
-
Video evidence
-
Location and movement analysis
-
Behavioural observations
-
Digital intelligence reports
-
Supporting documentation
​
All evidential material is compiled into professionally structured reports designed to provide clients, solicitors and other relevant professionals with a clear, accurate and legally admissible understanding of the findings most importantly with consideration for how it may be used by you, your solicitor or other relevant legal professionals.
Operational Security (OPSEC), Confidentiality & Legality
Private investigations and surveillance operations require strict operational security and careful handling of information at every stage of the process.
​
All client information, communications, evidence and operational activity are handled with complete discretion and confidentiality. Access to sensitive information is tightly restricted internally and limited strictly to vetted personnel directly involved in the investigation on a need-to-know basis.
​
Non-Disclosure & Confidentiality Agreements (NDAs) form part of our standard operational procedures (SOPs) for all our clients and are issued prior to any consultation and engagement with us to ensure strict confidentiality from the outset.
​
Client matters are not circulated as a matter of routine and information is carefully managed to minimise unnecessary visibility, duplication and exposure. From initial consultation through to reporting and evidence handling, investigations are conducted with a deliberate emphasis on operational security, privacy and evidential integrity.
​
Private investigations are a sensitive and complex field. The wrong approach or advice can expose you to legal, financial and reputational risk.
​
Privat Security operates fully within UK law and in compliance with GDPR (General Data Protection Regulation) and maintains strict internal confidentiality procedures designed to protect both client privacy and the integrity of ongoing operations.
​
We are registered with the Information Commissioner’s Office (ICO) for data processing, and our investigators are full members of The Association of British Investigators (ABI) who work to the strictest professional and ethical standards
​
As a matter of operational practice, Privat Security does not publicly reference any clients, investigations or operational details. Discretion, confidentiality and control of information remain fundamental to the way we conduct every engagement.
​
We understand the importance of your privacy. Your enquiry, your identity and the details of your situation are treated with complete confidentiality.
​
All our investigations are conducted ethically and lawfully, ensuring that any evidence obtained is credible, defensible, and admissible in court.
How Much Does a Private Investigation or Surveillance Cost?
The cost of a private investigation or surveillance depends on a few factors, such as the complexity of the case, the operational requirements involved, the level of surveillance or intelligence gathering required, the locations involved and the anticipated duration of the investigation as a starting point.
​
Before any operational activity begins, we conduct an initial free, no obligation confidential consultation to understand the circumstances of the case, assess what is achievable and determine the most effective investigative approach based on the objectives involved.
​
At Privat Security, investigations are planned strategically and proportionately. We do not believe in unnecessarily prolonging surveillance operations, deploying excessive personnel or generating avoidable costs without operational justification.
​
Every investigation is structured to achieve the required objective as efficiently, discreetly and cost-effectively as possible whilst maintaining the highest standards of professionalism, legality and evidential integrity.
​
We maintain a transparent and professional approach to pricing. Clients are provided with clear guidance on any anticipated costs, operational requirements and expected timeframes prior to engagement, ensuring there are no hidden charges, unnecessary operational expenditure or unexpected billing throughout the course of the investigation.
​
We do not believe in unnecessary surveillance, vague billing or extending a case without purpose. Our aim is to resolve matters efficiently while maintaining the highest professional standard.
Confidential Private Investigation & Surveillance Consultation
If you are considering hiring a private investigator, the first step is a free, confidential, no-obligation bespoke consultation with one of our experienced investigation consultants.
​
This initial discussion allows us to understand the circumstances involved, assess the viability of the investigation and advise on the most appropriate operational approach based on your objectives and concerns.
​
During the confidential consultation, we can provide guidance on:
​
-
What can realistically and lawfully be achieved
-
The most appropriate investigative strategy
-
Potential operational considerations and risks
-
Expected timeframes and anticipated costs
-
Whether surveillance, intelligence gathering or other investigative methods are appropriate to the circumstances involved
​
We understand that many clients contact us during sensitive and uncertain situations. Our role is to provide experienced, professional guidance whilst handling all discussions with discretion, confidentiality and careful consideration for your privacy from the outset.
​
All consultations and enquiries are handled in strict confidence.
