National Private Investigators Ltd

Fantastic experience: A year ago, I received professional assistance from National Private Investigators and it made a real difference for me. At that time, I left a 5-star review on their website, but since that page is no longer available, I want to leave another one here to express my gratitude. Their service was discreet, efficient, and highly reliable. I truly appreciate the support I received and would not hesitate to recommend them to anyone in need of professional investigation services.

Fantastic experience: Great service!

Positive experience: Really 4.5 stars, my only grievance was their was a slight miscommunication on a couple of things but overall I was pleased with the end result, so thanks to Jack and co. for helping me with what I needed!

Negative experience: UK Private investigators that can't locate a UK resident, with an abundance of information on the individual. Not exactly confidence inspiring considering it's one of their advertised services.

Negative experience: I called these people to find out if they might be able to help me. My call was answered by someone called Jack. Had the phone dropped on me mid-sentence and each time I tried to phone back was put straight through to voicemail which means they ended the call on purpose. Not a great way to deal with someone contacting them for help with a sensitive matter.

Fantastic experience: Prompt, professional and pragmatic guidance. I am not sure how I could have resolved the issue I had without the expertise Jack and his team provided. Unreserved recommendation based on the experience I had.

Fantastic experience: I honestly can’t thank Jack and the team at National Private Investigators enough. From the very first enquiry, they were calm, professional, and completely transparent about what could and couldn’t be done. No false promises, unlike other agencies I spoke to, just clear advice. What impressed me most was the speed of their work. Within a few days, I had a detailed intelligence report that gave me confidence to take the right next steps. It’s clear these guys genuinely care about doing what’s right. Highly recommended.

Fantastic experience: Jack provided a concise, rapid and highly efficient service which provided the basis of success for our issue. Having never hired a PI before, Jacks clear website identified the many different accreditation's his company holds. They checked out. To me it was interesting to note that a lot of other PI firms don't identify their accreditation. It was THE differentiator for me. Thanks Jack and I would highly recommend your services.

Fantastic experience: Fast, reliable and friendly.

Fantastic experience: Jack and his team were absolutely fantastic from the very start. Communication, feedback, engagement

Fantastic experience: Jack was fantastic, he couldn’t have been more helpful and reassuring throughout the entire process. I’d definitely recommend for anyone else considering it to have a discussion with him about any concerns. He was great.

Fantastic experience: I had a situation that needed handling quickly, and I was lucky to come across NPI. Honestly, they were great, quick to respond, discreet, and easy to talk to. If you’re ever in a tough spot and need a private investigator in London, they’re the ones I’d go to again.

Fantastic experience: Jack provided comprehensive services from start to finish. I used him for an intelligence report and was impressed by the PII he uncovered online. He also conducted a boardroom bug sweep, both with clear, actionable recommendations that enhanced the posture. Highly recommend

Fantastic experience: Very thorough report. Was happy with their work and responsiveness and communication.

Fantastic experience: Jack was patient and polite when we spoke on the phone. He kept me updated throughout the investigation on its progress and I got the information I wanted, and more. Brilliant!

Fantastic experience: NPI have been amazing, I will definitely recommend to anyone that’s looking for a private investigator in London. Very thorough. Great communication throughout.

Fantastic experience: Amazing service. Straight to the Point. Best investigators in the u.k.

Fantastic experience: Exceptional Service I recently enjoyed experiencing top-notch service from NPI. From the moment I reached out, I was impressed by their professionalism and efficiency. They were incredibly knowledgeable, patient, and attentive. They took the time to understand my specific requirements and provided tailored solutions. The entire process was seamless and stress-free. I highly recommend NPI to anyone seeking these services. Their commitment to customer satisfaction is truly commendable.

Fantastic experience: Having known Jack for many years from time served in the army, I knew I could put my trust in him to investigate a fraudulent matter. Jack was efficient, attentive, and overall fantastic to work with, exactly what I expected. If anybody is looking to use Jack and his team I would highly recommend him!

Fantastic experience: Jack worked absolute magic. I honestly really didn't think any private investigator would have success with the investigation I needed. Jack's success absolutely blew me away and I don't know how he managed to get it done, but he did! Honestly, I'm forever grateful to him and his team for the work they did. This means so much to me. Absolutely stunning work. I chose Jack for two reasons: 1) Primarily, I could see, by his videos and the way he talked, that he has a strong moral compass and desire to do the right thing, and 2) his extensive Army reconnaissance experience, and that of his team. The fact that he and his team together have experience in intelligence gathering, counterterrorism, covert reconnaissance, and special forces, all of this made me confident about their abilities. All things considered, I don't think I could have possibly chosen a better investigator. You've solved a very long-standing mystery that I thought would remain unsolved. I had very limited information that you had to piece together and honestly I was skeptical if it was even possible to accomplish. But somehow you pulled it off. Thank you Jack - you truly are the man! My gratitude knows no bounds. I don't know how to even begin to thank you.

Fantastic experience: I needed to gather some evidence very quickly so I reached out to Jack. I can highly recommend him for his flexibility, quick and discreet approach, his empathy and sensitivity. Thank you for a great job done.

Fantastic experience: I can truly say that I have received a 100% service. Jack took the time to call me. He was polite, courteous and attentive to my needs.

Thank you, Jack and your team.

They were very approachable and easy to communicate with especially with some cultural differences and info.Would definitely recommend this organisation....reasonably priced...responsible ...and responsive.

Fantastic experience: Worked with Jack on a B2B level for the past year now, it is a pleasure working with someone who meets deadlines, provides accurate and timely information, as well as putting relationships before money. I recently purchased his bug-sweeping services. I am very pleased with the price-to-value ratio. Not only did he successfully find 3 bugs, but he also talked me through safe practices moving forward (which means I probably won't need to use him again for this type of sweep) and I feel an instant increase in my business's overall security. This is a great business that solves high-level problems quickly.

Fantastic experience: Jack was brilliant. He instantly put me at ease and explained the process very clearly. He is extremely knowledgeable, personable and professional and was sensitive to my situation. Jack provided some very useful tips that I should look into upon completion of the job. Many thanks Jack for making me feel safe and comfortable again in my own home! I would highly recommend Jack. Sarah
