I instructed Tony Sykes as an expert witness in regards to a SAP matter. I found Tony to be extremely proficient and knowledgeable in the case matter and found his report to be very informative and to the point in regards to the key findings. From my initial enquiry I found Tony Sykes and IT Group to be very prompt and efficient with their analysis and would not hesitate to use them with any matters in the future.

We instructed IT group (Mr Tony Sykes) as experts in a complicated contractual dispute involving an electronic scrolling visual display unit. The report prepared by Tony [Sykes] was comprehensive yet dealt concisely with the key issues. The report was instrumental in enabling us to obtain a satisfactory settlement of the claim brought by our client. The administration of IT group in terms of arranging site inspections preparation and delivery of the report and dealing with further enquiries was excellent.

I was impressed by IT Groups incredibly fast turnaround. They were very thorough and the investigation was carried out with great attention to detail. The report was presented with clarity and ultimately helped me convince the counterparty to face up to the error of their ways, leading to a great settlement for my client.

Can I take this opportunity of thanking you for your help in this matter. Our client was charged with a serious criminal offence and the expert report which you prepared for us was extremely helpful and instrumental in persuading the Crown Prosecution Service to discontinue the case.

We run a number of large IT related litigation claims each year and Jason Coyne is by far and away the best expert we have come across. He is a rare breed because he understands system architecture and programming language. Unlike so many IT experts, he can actually get into the systems himself and determine what the problem is and so then we can establish who is responsible for it.

From the initial instruction Jason Coyne provided robust, coherent and purposeful advice which paid particularly close attention to the instruction, a trait not always forthcoming in experts. I have no doubt his intervention was pivotal in making the other side face up to reality and eventually led to settlement. I would recommend him without hesitation.


David [Sykes] is a consummate professional. I have worked closely with him in the resolution of complex IT disputes and his expert input has been invaluable, not only to me but to the paying client.

David [Sykes] is an excellent expert who knows his subject very well and has the skill to explain and present his opinions with clarity.


I would recommend Jason Coyne. His written and oral presentation of evidence was clear, logical and persuasive.
