    Private Investigator Q&A


    How long does it take for an investigation to commence in Glasgow?

    The start time for an investigation varies depending on the complexity of the case, but our field agents can typically begin within a few hours. Whether it’s surveillance, people tracing, or gathering evidence, we mobilise quickly to ensure your investigation starts as soon as possible.

    How much does it cost to hire a private investigator in Glasgow?

    Costs vary depending on the case but typically range from £35.00 to £275.00 per hour. We offer clear pricing through our “Free Estimate” tool and provide daily rate packages for long-term investigations.

    How to hire a private investigator at Dion International?

    • Contact us for a free consultation via phone, email, or our contact form.
    • Review pricing and complete the required paperwork.
    • The investigation begins once we receive your approval and cleared balance. You will be updated throughout the investigation, with a final report provided upon conclusion.

    How to find a local private investigator near me in Glasgow

    Search for “private investigator near me,” verify reviews and location details, and schedule a meeting to ensure credibility. Dion International is based in Edinburgh and meets clients in person.

    Why do I need more than one surveillance officer?

    While one officer may seem cheaper, the increased risk of detection can prolong the operation. A team approach ensures efficient results, saving you time and money in the long run.  Feel free to contact us to discuss how two or more surveillance officers is better than one.

    Why choose Dion International Ltd?

    Unlike other private investigation companies in Glasgow we begin each case with a thorough analysis to optimise deployment, minimising costs and ground time. Our highly trained investigators manage both sensitive personal cases and complex business disputes globally, always prioritising professionalism, discretion, and cost-effectiveness.

    Are your services discreet?

    Yes absolutely, all our services across Glasgow are conducted with the utmost discretion. We prioritise confidentiality while delivering reliable, cost-effective solutions. For more details on our discreet approach, feel free to contact us.

    What are the three types of surveillance?

    • Static Surveillance: Two operatives monitor a location or individual.
    • Mobile Surveillance: A team follows an individual using advanced technology.
    • Rural Surveillance: Teams of two or more will monitor activity in rural areas.  Examples of this would be during fly-tipping and farm machine theft covert operations.

    Are private investigators legal in Glasgow?

    Yes, private investigators operate legally under GDPR and RIPSA regulations. They must follow strict legal guidelines to ensure all actions are admissible in court.

    What can’t private investigators in Glasgow do?

    Private investigators cannot access devices without permission, obtain bank records without authorisation, access criminal histories unless publicly available, or remotely access local authority CCTV systems.  An experienced private investigator just knows where to look.
