Our Private Investigation Service Costs
Why Professional Expertise Matters
You may be wondering whether it’s worthwhile investing in a private investigator in Cardiff. Private investigation is a highly specialised profession requiring extensive training, professional qualifications, and years of operational experience. Our operatives deliver discretion and compile robust evidence packages with comprehensive reporting that meets the highest professional standards.
The Cost of Compromise
Many private investigations fail catastrophically when clients attempt to handle matters independently or engage cut-price agencies lacking proper expertise and ethical standards. When surveillance operations or vehicle tracking devices are deployed by untrained personnel and subsequently detected by the subject, all evidence becomes inadmissible and future investigation opportunities are permanently compromised—rendering your situation entirely unresolvable.

Frequently Asked Questions – Relationship Investigations
How do I know if my partner is cheating, and can you provide proof?
Signs of cheating include secret behaviour with a phone and unexplained absences. The surveillance experts we have can provide photographic and video evidence which is legally admissible, logs, and reports that can certainly prove infidelity.
What does relationship surveillance actually involve, and is it legal?
We can discreetly monitor your partner’s activities in public using our surveillance techniques and equipment. We can’t just carry out surveillance wherever we want. If we need to go on a private property, we can send a letter to the property owner to inform them of our intention. The evidence that has been gathered focuses on the public behaviour and interaction.
How long does a typical infidelity investigation take to produce results?
Most investigations of relationships yield early findings after 5-10 days with complex cases taking generally 2-3 weeks to compile evidence. Our well-experienced operatives regularly identify patterns quickly, with many cases generating conclusive evidence during the first week of surveillance.
Will my partner discover that I've hired a private investigator?
Our spies are trained in covert surveillance, use unmarked vehicles, professional-grade surveillance equipment, and effect counter-detection. The investigation is done in absolute secrecy so that your partner does not know about it.
Can the evidence you gather be used in divorce proceedings?
Yes, our evidence packages are prepared to the standard required for family court. We provide in-depth reports, time-stamped photos, statements from witnesses, and full evidence which solicitors can use easily for divorce settlements, custody arrangements and financial disputes.
Frequently Asked Questions – Corporate Investigations.
How can you help investigate suspected employee theft or fraud within our company?
Our corporate fraud specialists undertake a thorough financial audit, covert surveillance, digital forensics and background investigation to trace theft, embezzlement or fraud. Our team collects valid evidence like witness statements, financial investigation, and surveillance that can be used for disciplinary or criminal action.
What is involved in investigating a potential breach of restrictive covenants by former employees?
Our investigations keep a watch on ex-employees who are violating the non-compete clause, client poaching, etc. We do secret watching, study social media activity, look into new job arrangements, and write down unlimited contact with ex customers or ex competitors to get strong proof for getting a court order.
Can you perform due diligence checks on potential business partners or acquisition targets?
We investigate financial soundness, compliance, litigation, key personnel and reputation as part of our due diligence investigations. We check credentials, uncover hidden liabilities, assess management integrity, and conduct risk assessments to ensure your investment and business decisions are sound.
How do corporate bug sweeps work, and how often should our offices be checked?
Our TSCM experts utilize military-grade detection gear to locate spying devices, hidden cameras and other electronic surveillance threats. For areas considered high-risk, we recommend sweeping them on a quarterly basis. We also recommend checking sensitive negotiation areas on a monthly basis, and, lastly, checking areas immediately following a breach or drawdown of personnel.
What evidence standards do you maintain for corporate investigations that may lead to legal action?
Corporate evidence is collected to legal admissibility standards like chain of custody documentation, witness statement protocols, best forensic practices, etc. Our investigators keep detailed records of their investigations. They use certified digital forensic tools that meet the law and work with lawyers to ensure that evidence can withstand the scrutiny of an employment tribunal, a commercial dispute or a criminal trial.
