How it works

Following an initial discussion regarding any of our services, we will send you a free, no obligation fixed quote. There are no other fees or charges in addition to our original quote. If you decide to go ahead based on our quote and recommended course of action, you should send us full details of the case.

On receipt of the fee we will begin the investigation. You should inform us as soon as possible during the investigation if your requirements change. If so, a revised agreement will be emailed to you for payment so that we can go ahead.

We will discuss your case with you stage-by-stage. At its conclusion, we will email you a report of our findings, together with any time and date stamped images obtained during the investigation. An invoice marked as paid will also be sent to you.
