I reached out to Reveal Private Investigators in Birmingham when I needed some clarity on a personal issue and was immediately impressed by their discreet yet thorough approach.
The investigator who took my case walked me through their process in detail, covering everything from covert surveillance and GPS vehicle tracking to the option of a lie detector test if necessary.
I found their use of advanced technology, especially in bug sweeping and digital tracking, to be highly efficient.
A friend of mine who had previously used their matrimonial investigation service told me how reliable their evidence gathering was, as it often held up in court. It definitely gave me the confidence to move forward.
However, I did find that their reports took slightly longer to complete, likely because they focus heavily on accuracy and verification at each stage.
Even so, I appreciated their professionalism and the wide range of services they offer, which also include employee investigations and asset tracing for corporate clients.
Super helpful and explained the services clearly
“I had reason to contact Reveal PI and was hugely impressed by their services. From my initial contact, the service was amazingly quick and efficient. I had spoken to David, who was super helpful and explained their services very clearly and the results that can be achieved, whilst showing empathy and extreme care for my situation. I can highly recommend them to anyone and would most definitely look to use them again. You won’t be disappointed. Thank you for all you have done to support me.”

I agree with all the positive reviews. They were amazing, professional, and I want to thank you all the entire team that helped me on a sensitive matter. 100% recommended.”

What initially caught my attention about Anderson & Co Surveillance in Birmingham was their reputation for precision and discretion in private investigations.
When I needed some clarity on a sensitive personal matter, their team was quick to respond and even arranged a consultation for me the very same day.
I was genuinely amazed by their efficiency, from assigning skilled surveillance specialists to conducting thorough background checks using both digital and field methods.
During one of my visits, I had a chat with a former client who had utilised their people tracing service to track down a long-lost business partner. The case was handled with accuracy and professionalism.
Beyond that, it was reassuring to see how the investigators protected sensitive information and maintained full confidentiality throughout the process.
I also noticed that their rapid nationwide response system allows them to deploy anywhere in the UK at short notice.
The only drawback I found was their higher pricing, which might not be suitable for clients needing smaller or shorter investigations.
Completely simple and straightforward process
“We used Dan to locate a distant family member. Completely simple and straightforward process. Reasonably priced too. Absolutely no hesitation in using again if needs be, and highly recommend. Thank you.”

Contact Details: +44 121 769 1626
Operating Hours: Monday to Sunday: 7:00 AM to 9:00 PM
When a coworker opened up to me about fidelity matters, she reached out to Sentry Private Investigators Ltd. She was impressed with how thorough their infidelity investigation services were.
I later found out that their team specialises in discreet covert surveillance to track partners’ movements and gather photographic and video evidence that’s suitable for legal use.
They also combine these methods with digital verification techniques to make sure all their findings are accurate and admissible in legal situations.
I also spoke with a previous client who had turned to Sentry for help in confirming suspicions and gathering solid evidence for a divorce. The investigators maintained confidentiality while providing detailed reports.
In addition to infidelity investigations, Sentry offers services like cohabitation investigations, which cater to both private and corporate clients with a comprehensive range of services.
One minor problem is that due to the high demand for their surveillance teams, it can sometimes take a bit longer than expected to schedule urgent cases.
Did an excellent job in helping find some information
“Dealing with Sentry Private Investigators has been a delight. I found the services to be quick and very reasonably priced compared to competitors. Ben did an excellent job in helping me find some information and will consider using him again in the future should the need arise. Top bloke!”
– Damon Roy, Google Review

Their team was discreet and really listened to my concerns, which made me feel confident that I was in good hands. The results they provided were detailed and gave me exactly what I needed. Highly recommended.”

4. The Alert Group TAG Ltd

Address: Office 1, Izabella House 24-26 Regent Place, West Midlands
Contact Details: +44 7456 578597
Operating Hours: Monday to Sunday: Open 24 hours
The first time I came across The Alert Group (TAG) Ltd in Birmingham, I learned that they offer investigative services. They handle some pretty intricate cases, like looking into corporate theft and investigating employee misconduct.
Their team even conducts surveillance throughout Birmingham, using advanced tracking systems and video evidence to document activities discreetly.
A previous client shared that TAG has a due diligence service before entering a business partnership. On top of that, the investigators took the time to verify company records, revealing details that protected them from a costly mistake.
The client also highlighted how thorough and confidential the whole process was, with the findings laid out in a clear and factual report.
Plus, I admire how TAG combines physical surveillance with digital intelligence to ensure that every piece of information is double-checked. They also provide close protection services with trained specialists.
One problem is that their investigation rates can be a bit steeper compared to small local firms.
Gave some really honest advice
“I got in contact with Ryan, the director, when I needed some help finding out some information. He gave me some really honest advice, and he advised me on the best way to go about it. Because of his honesty and professionalism, he actually didn’t get any work out of it, but I would always use this company in the future. He also checked up on me a few weeks later to ask how I was doing. I was really happy with the overall experience.”
– Sam Workman, Google Review
Offered lots of advice on the situation and ways you could go forward
“Highly recommended, I rang Ryan in desperation as my situation was awful to say the least. Ryan took his time out to listen to me and my situation. He also went above and beyond to help me and got the information I needed really easily. I couldn’t believe how fast he got it with no problems. Ryan also offered me lots of advice around my situation and ways that I could go forward. This is more than just a job. Ryan will genuinely help you and make sure he gets the results you want, and ensure he does his very best. I would like to say a huge thank you!”

5. Keith Parsons Enquiry Agency

Address: 55, Royal House, Princes Gate, Solihull B91 3QQ
Contact Details: +44 121 744 4689
Operating Hours: Monday to Sunday: 8:00 AM to 7:00 PM
I found exactly what I needed with Keith Parsons Enquiry Agency when I needed someone traced urgently and served legal papers the next day.
I actually love how they tailored their status reports and process services, so they fit exactly into my tight schedule. When I used their status-report service to check a debtor’s financial standing, the results were sent without delay.
Even better, the team managed to track down the person I was looking for, even though I had only partial details.
Not long after, they served a statutory demand and got the certificate of service to me within 24 hours.
On the flip side, their package options weren’t laid out in full detail up front, and I spent extra time asking for a breakdown of costs.
But for a firm which balances speed and reliability in legal investigations, I’d definitely say they’re a strong choice.
Replied promptly and professionally with a competitive quote
“I contacted Keith Parsons by web form on a Wednesday evening. They replied promptly and professionally with a competitive quote for serving court documents from the family court on short notice. Within 24 hours, the papers had been served. A certificate of service was provided to me promptly the following morning. Great service, I would recommend it!”

Tracing service and process server service were both done very quickly
“I used their tracing service and process server service to serve divorce petitions. Both were done very quickly. Highly recommended. Will use again if needed. Communication was great with both Chris and Lorna, who answered all my questions. Thanks again for your help.”
