The hardest step is always the first. Getting in touch is the very start of your journey to the answers and evidence you need.

We will you listen to your story and advise you on the best course of action in terms of budget and time. 


The next step is to gather all information you already have and then we begin our information collection ahead of the investigation beginning. 

The most important part here are the objectives to achieve are set and agreed.  

Next, the heavy lifting is done by us whether it be surveillance, people tracing or general investigating we get to work for you.

Lastly, once the investigation is complete we provide you with a report of our findings, usually within 24 hours.

This will include everything we find and if you used surveillance we send you over the the video too. 

The answer to this question is all relevant to exactly which service or group of services you require. To find a full breakdown of our prices please visit our Costs Page

100% completely legal within the United Kingdom. All of our methods during an investigation are conducted within UK law and all of our evidence is admissible in court if needed. 

Always. From the moment you begin speaking with us whether it is to simply ask for advice or the work is prolonged, all of it is completely confidential. 

We will only share details outside of our client/investigator relationship with your explicit permission. 

Within the UK, the private investigation industry is not licenced and at the moment relies on trade associations policing the industry. We are members of a professional trade group, The Institute of Professional Investigators. Should you ever have any complaint about our level of service, you can make a complaint to these trade bodies. 

One of the most asked questions we receive is this however it is not feasible or in any way legal within the UK to hack or access into someone’s phone without their explicit permission. 

We can forensically search a phone but we must have permission from the owner of the device. 

We accept bank transfers, cheques and all card payments are processed via Stripe. We do accept cash if you need to keep the payment away from your bank statement for protection purposes and to be discreet. 

Predominately we work within the Midlands region being based in Derby however we can work nationwide for all investigative work. 

We love to meet our clients as it builds trust and lets you put a face to your investigators. We can meet you at either our main office in Castle Donington near East Midlands Airport or our Nottingham office. Should these not be feasible or preferred we can also meet you closer to home should you wish. 

This is completely set by you. We understand our client’s may live with people who are being investigated such as a cheating partner so we ask you the preferred times and methods of when and how we talk to you. We can email, call, text or WhatsApp. 

The trade associations at the moment are in talks with the DVLA to enable professional agencies access to it’s database similar to car parking companies, however at the moment we cannot locate someone from a vehicle registration plate of a vehicle. Should you have been involved in a hit and run incident we can apply to the DVLA on your behalf but cannot guarantee any results. 

During your initial enquiry we will listen to your situation and advise the best steps for you to take. This will be in terms of the most cost effective, time efficient and least intrusive way possible. 

If it will not be an investment on your part, we will advise you as such and try to advise another way to help your situation.
