The Role of Private Investigators in Insurance Claims

Private investigators can support insurance claims by establishing facts independently: reconstructing events, verifying publicly observable activity, interviewing witnesses, checking documents and open sources, preserving evidence and reporting inconsistencies. Their role is investigative, not judicial. An investigator does not decide whether a claimant is dishonest, whether policy cover applies, what compensation is payable or whether a criminal offence has been committed. Those decisions sit with insurers, legal advisers, courts and law-enforcement bodies as appropriate.

At Trojan Investigations, our insurance-related work is evidence-led and proportionate. A suspicious indicator is a reason to ask a clearer question, not permission to assume fraud. That distinction matters because genuine claimants can display unusual behaviour for perfectly legitimate reasons, while organised fraud can appear superficially plausible.

The Scale of Detected Insurance Fraud

The latest full annual detected-fraud figures published by the Association of British Insurers before this update relate to 2024. The ABI reported that insurers identified more than 98,400 fraud-related general-insurance claims worth £1.16 billion. Motor accounted for 51,700 detected cases worth £576 million, while 18,700 deceptive property claims were identified at a value of £189 million. Exaggerated loss was the most common type reported, amounting to £466 million, and insurers were estimated to have prevented 684,800 fraudulent applications.

These are detected-fraud figures, not an estimate that every suspicious or declined claim is fraudulent. The ABI’s general fraud page presents a rounded £1.14 billion figure, while its dated 17 November 2025 press release reports £1.16 billion; we use the dated release for this article.

Insurance Investigation Is About Verification, Not “Catching People Out”

A professional investigation begins with the claim question. What fact is in dispute? Which evidence would confirm, weaken or leave that issue unresolved? For a motor claim, it might be the circumstances of a collision. For an injury claim, it might be the consistency between reported functional limitation and publicly observable activity. For a property loss, it may concern provenance, ownership, timing or the claimed sequence of events.

Our business investigations approach avoids fishing expeditions. Broad monitoring without a defined purpose creates privacy and evidential problems and can generate large amounts of irrelevant information. A proportionate instruction identifies the issue first and chooses the least intrusive useful method.

Common Insurance Fraud Patterns Investigators May Encounter

The Insurance Investigation Process

Surveillance in Insurance Claims

Surveillance can be useful where there is a specific factual issue that can be observed lawfully in public. Our surveillance services may document movements, activities, meetings or routines within a defined period. The report should state exactly when observation began and ended, periods when the subject was not visible, and what the footage actually shows.

Repeated or intrusive monitoring can also create harassment and data-protection concerns. The fact that a person is in a public place does not mean every form of prolonged observation is automatically lawful. Purpose, necessity, proportionality and the manner of the surveillance matter.

Witness Enquiries and Interviews

Witnesses can clarify sequence, identity and context, but memory is imperfect. A good investigator avoids leading questions and records what the witness personally saw or heard rather than encouraging speculation. Neighbours, colleagues and third parties should not be told unnecessary confidential details about the claim merely to prompt information.

Where the matter may become contested litigation, our legal and litigation support approach places additional emphasis on identifying the source of each fact and distinguishing direct knowledge from hearsay or inference.

Document and Digital Evidence

Claim files may contain photographs, invoices, receipts, repair records, correspondence, call notes, location information voluntarily supplied by a party and other digital material. Investigation can help compare dates, identify duplicates, check public business details and test whether documents are internally consistent. Specialist digital forensic work may be required where authenticity or device-level examination is genuinely in issue.

Private investigators do not have a general right to break into devices, obtain private cloud accounts, retrieve banking records or intercept communications. Unauthorised access can engage the Computer Misuse Act and other laws, and evidence gathered unlawfully may create serious difficulties for the investigation and client.

Social Media and Open-Source Evidence

Public social-media material may provide useful context, but it is easily misunderstood. A photograph may be old, reposted or staged; a location tag may be inaccurate; a profile may belong to a different person; a short clip says little about what happened before or afterwards. Material should be captured with date, source and URL information and checked against the wider chronology.

Public availability does not remove UK data-protection responsibilities. Investigators and their clients still need a lawful basis for processing personal data and should retain only what is relevant to the purpose.

Background Enquiries: Relevance Comes First

The original version of this article suggested broad checks of a claimant’s “personal and financial history”. That is too wide as a general proposition. A legitimate investigation should not trawl through someone’s private life hoping to find something damaging. Background enquiries should relate to a defined issue in the claim and use lawful sources. Protected banking, tax, health or police information is not available to a private investigator merely because a claim is disputed.

Claimant Fairness and False Positives

Fraud prevention protects honest policyholders, but investigations must also protect innocent claimants from being treated as guilty because of an algorithmic flag, lifestyle assumption or ambiguous footage. Indicators are often designed for triage: they identify cases that may require human review. They are not proof.

Good investigations test alternative explanations. A person may have several addresses for legitimate reasons. A repair invoice may look unusual because a small trader uses informal paperwork. A claimant may appear active on one day while experiencing significant limitations on another. Reporting these possibilities is not weakness; it is proper evidential discipline.

Insurance Fraud and the Wider UK Response

The Home Office’s Insurance Fraud Charter brings government, insurers and sector bodies together around information sharing, professional enablers, justice outcomes, illegal insurance firms, fraud classification, consumer communications and victim support. The government’s Fraud Strategy 2026 to 2029 also treats fraud as a major national resilience and justice issue.

That wider context reinforces why private investigators should produce reliable, explainable evidence rather than inflated “success rates”. A weak or unfair investigation can harm a genuine claimant, undermine civil proceedings and make criminal referral less effective.

Evidence Handling and Reporting

An insurance investigation report should identify the instruction, scope, dates, investigator, source of evidence, continuity of files and limitations. Original media should be preserved where possible, working copies managed securely and edits or extracts clearly distinguished from the source material. If a report includes an inference, the underlying facts should be stated so the reader can judge the reasoning.

When Is a Private Investigator Most Useful?

If an insurer, solicitor or business requires a scoped investigation, you can book a confidential consultation. The scope should be agreed around the decision the evidence is expected to support.

Working With Experts Without Overstepping Roles

Reports should make that boundary explicit. An investigator can say that video records a person carrying an item at a stated time. They should not convert that observation into a medical opinion. They can record that an invoice number appears twice. They should not assert an accounting fraud without the necessary evidential and professional basis. Clear role boundaries make the final evidence stronger, not weaker.

Complex claims often involve specialists. Engineers may analyse vehicle damage or causation; medical experts assess injury and prognosis; forensic accountants examine financial loss; digital-forensics practitioners examine devices or files under an appropriate authority; solicitors advise on legal relevance and procedure. The investigator’s role is often to assemble the factual chronology and identify where specialist opinion is needed.

When an Investigation Should Stop

Stopping can also be the correct outcome when the evidence supports the claimant’s explanation. An investigator is not paid to manufacture suspicion. Balanced work can save insurers money by showing that a line of enquiry is unlikely to justify further expense and by reducing the risk of unfairly escalating a genuine claim.

Good investigation planning includes a stopping condition. Surveillance should not continue indefinitely because a client is dissatisfied with neutral results. Witness approaches should stop when further contact would be oppressive or unproductive. Open-source monitoring should not become continuous tracking without a fresh justification. The scope should be reviewed as evidence changes.

Organised, Connected and Repeat Fraud Concerns

Where evidence suggests organised criminality, professional enablers, staged collisions or other serious offences, the client may need to consider referral to the relevant insurer fraud function, the Insurance Fraud Bureau, law enforcement or legal advisers. A private investigator does not replace those bodies and should preserve evidence in a form that allows them to assess it independently.

We therefore distinguish between a link, a pattern and evidence that supports an allegation. For example, two claimants using the same repair business is a link. A series of claims involving the same participants, inconsistent accounts and supporting records may be a stronger pattern. Even then, the report should explain the underlying facts rather than label the network as fraudulent without sufficient evidence.

Some insurance investigations involve more than one claimant. Connected claims may raise questions about shared addresses, vehicles, repairers, introducers, witnesses, contact details or repeated patterns. Link analysis can be useful in these cases, but the existence of a connection is not the same as proof of conspiracy. Families, colleagues, neighbours and local businesses naturally share contacts and locations.

From Red Flag to Evidence: Why Investigation Design Matters

Before intrusive enquiries are considered, the investigative question should be narrowed. If the concern is ownership of a claimed item, documents and provenance may answer it more directly than surveillance. If the concern is who was driving, chronology, witnesses, CCTV or scene evidence may be more useful. If the concern is a claimed physical limitation, public observation may have some relevance, but only to the specific activities recorded. This method-first approach reduces unnecessary intrusion and produces evidence that is easier to explain later.

Insurers receive large volumes of information and increasingly use rules, data matching and analytics to identify claims that may deserve closer review. That can be efficient, but it creates a crucial distinction between selection for investigation and proof of dishonesty. A red flag may reflect nothing more than a common surname, an unusual but legitimate purchasing pattern, a previous claim, a late report or a mismatch created by poor data quality.
