Private Surveillance Under Scrutiny: Why Purpose, Proportionality and Professional Standards Matter
Recent reporting has placed the use of private surveillance under renewed scrutiny after businessman Arron Banks was reported to have commissioned private investigators to examine Conservative Party chair Kevin Hollinrake.
The Guardian reported on 16 August 2026 that Banks had hired investigators from Precision Risk and Intelligence to look into Hollinrake, following earlier reporting that Banks had also commissioned enquiries into Sunday Times journalist Gabriel Pogrund. Banks appeared to confirm the work, while Reform UK said it had no involvement in the surveillance.
For businesses, legal teams and private clients, the wider lesson is not that surveillance itself is inherently inappropriate. It is that professional surveillance should begin with a legitimate objective, be proportionate to that objective and be conducted within the relevant legal and professional framework.
Surveillance is a Method, Not an Objective
One of the most important distinctions in professional surveillance is between the reason for an assignment and the surveillance method itself.
Surveillance can be appropriate in matters involving:
- Fraud or suspected financial misconduct.
- Insurance claims.
- Employment disputes.
- Commercial litigation.
- Breach of contractual restrictions.
- Cohabitation or family-law matters.
- Theft or diversion of assets.
- Other legitimate factual enquiries.
But the fact that surveillance is technically possible does not mean it is automatically the right response.
The first question should be:
What information is genuinely required, and why?
A clearly defined objective helps determine whether surveillance is proportionate, whether another method would be more appropriate and what information should actually be collected.
Conflict International's Surveillance Services are structured around that principle: define the objective first, then determine the most appropriate and proportionate method.
Purpose and Proportionality Matter
A professional surveillance assignment should have a legitimate and clearly understood purpose.
For example, an insurer may need factual evidence concerning activity relevant to a claim. An employer may need to establish whether an employee is undertaking undisclosed outside work. A legal team may require observations relevant to ongoing litigation.
In each case, the surveillance is tied to a specific factual question.
Proportionality matters too.
A minor concern does not automatically justify extensive observation, and an assignment should not continue indefinitely simply because additional information might be available.
Relevant considerations can include:
- The seriousness of the issue.
- The information already available.
- Whether less intrusive methods could answer the question.
- The likely evidential value of surveillance.
- The duration required.
- The locations involved.
- The privacy implications.
- Whether the method remains appropriate as circumstances change.
Proportionality is not only a legal concept. It is also a practical safeguard against gathering unnecessary information that does not assist the client.
Professional Standards Reduce Risk
The current public debate also demonstrates why professional standards matter.
Poorly planned or overly intrusive surveillance can create legal, reputational and operational problems for the client as well as the investigator.
Professional surveillance should therefore involve:
- A clearly defined instruction.
- Appropriate legal and operational assessment.
- Proportionate methods.
- Accurate contemporaneous reporting.
- Proper handling of photographs and video.
- Clear distinction between observation and interpretation.
- Respect for relevant privacy and data-protection requirements.
- Appropriate supervision and review.
Our existing guide to the legality and standards of private surveillance in the UK examines these principles in greater detail.
Surveillance Should Establish Facts, Not Confirm Assumptions
Clients often approach surveillance with a suspicion.
That is understandable, but professional investigators should not begin with the assumption that the suspicion is correct.
The purpose is to establish facts.
Surveillance may show that an individual visited a particular location, met another person, drove a particular vehicle or undertook a particular activity.
Those are observations.
They do not automatically establish fraud, dishonesty, motive, medical capability, breach of contract or criminal conduct.
Those conclusions depend on the wider evidence and, where relevant, legal assessment.
This distinction is especially important where surveillance material may later be scrutinised by solicitors, insurers, employers or a court.
High-Profile Subjects Create Additional Risk
Assignments involving journalists, politicians, executives, public figures or other high-profile individuals can carry additional reputational considerations.
The underlying legal rules may not necessarily change simply because a subject is prominent, but the consequences of poor judgement can be significantly greater.
Clients should therefore consider:
- Whether the purpose of the assignment can be clearly justified.
- Whether the proposed methods are necessary.
- Whether the scope is broader than it needs to be.
- Whether the work could create disproportionate reputational risk.
- Whether specialist legal advice should be obtained before proceeding.
The more sensitive the context, the more important it becomes to document the purpose and reasoning behind the assignment.
Corporate and Litigation Surveillance
For businesses, surveillance may be appropriate where there is a legitimate corporate concern.
Examples include:
- Suspected employee misconduct.
- Undisclosed competing business activity.
- Theft.
- Diversion of company assets.
- Breach of contractual restrictions.
- Fraudulent absence.
- Activity relevant to a commercial dispute.
However, surveillance should not automatically be the first step.
A corporate concern may be better addressed through document review, corporate intelligence, digital evidence, public-record research, internal audit or appropriate HR and legal processes.
The method should follow the evidence requirement.
Surveillance can also support civil litigation where factual observations are relevant, including personal injury claims, insurance disputes, employment matters, commercial proceedings and matrimonial cases.
Where surveillance forms one part of a wider legal strategy, clear instructions from the legal team help keep the work focused and proportionate.
Accurate Reporting Is Essential
The quality of a surveillance report is as important as the observation itself.
A professional report should clearly record:
- Date and time.
- Location.
- Relevant movements.
- Individuals observed.
- Vehicles.
- Activities.
- Photographic or video material where appropriate.
- Gaps in observation.
- Any limitations affecting identification.
It should not exaggerate.
If an individual cannot be confidently identified, the report should say so. If activity is ambiguous, it should remain ambiguous rather than being converted into a conclusion.
That is particularly important where the report may influence litigation, employment action or another significant decision.
Privacy and Reputational Risk
Professional surveillance in the UK sits within a wider privacy and data-protection environment.
The fact that an activity takes place in public does not mean that every form of monitoring is automatically appropriate in every circumstance.
The purpose, method, duration and information collected all matter.
Clients should also consider how an assignment would appear if it became public.
A useful question before commissioning surveillance is:
Would the organisation be able to explain why this work was necessary and proportionate if the instruction later became public?
If the answer is unclear, the proposed scope probably deserves further review.
A Practical Framework Before Commissioning Surveillance
Before instructing surveillance, clients should consider:
- What specific information is required?
- Why is that information relevant?
- What evidence already exists?
- Could another method answer the question?
- Is surveillance proportionate to the issue?
- How long should the assignment reasonably continue?
- Are there particular privacy or reputational concerns?
- How will the resulting information be used?
- Does the matter require legal advice before surveillance begins?
This approach helps ensure that surveillance remains a focused evidence-gathering tool rather than an open-ended exercise.
The recent reporting around Arron Banks has again brought private surveillance into the public spotlight. The circumstances are politically sensitive and should not be treated as representative of every surveillance assignment.
The wider lesson, however, is useful.
Professional surveillance depends not only on what can be observed, but on why the surveillance is being conducted, whether the methods are proportionate and how the information is handled and reported.
For legitimate corporate, legal, insurance and private matters, surveillance can provide valuable factual information that may not be available through other methods.
But it should always begin with a clearly defined objective.
If you require discreet surveillance support in connection with a corporate, legal, insurance or private matter, contact Conflict International to discuss an appropriate scope.
