In some surveillance investigations, it may not be possible to know the exact start date and time of an operation; in this type of case, our agents may need to be on standby and wait for a trigger to start the operation. A typical trigger may be when a subject goes to a certain place or a certain event happens. The main advantage to this is that costs are kept to a minimum because we only attend when absolutely necessary, but the disadvantage is a risk that the time taken to deploy could result in a loss of evidence.
Surveillance is usually booked to start at a certain time and date; however, if you require agents on standby, we would process the job as normal and pass the case details to our agents. They would then be fully prepared to attend, once instructed. Unfortunately, due to the nature of the particular service, there is a risk that the agents could be unavailable at the time; there is no way of avoiding this risk apart from a firm booking.
If you do decide a firm booking is more appropriate, you can still cancel up to 16 hours in advance with no cancellation fees.
