Surveillance Services

At Line of Inquiry, we have our own in-house surveillance operatives, led by a former military intelligence officer (unlike other companies who claim that they are, but in fact, are not).

Our other team members include a specialist Senior Surveillance officer of 23 years’ experience with the Metropolitan Police. We charge standard industry, UK rates. We also have a further three female operatives and surveillance investigators in every county of the UK. We can at short notice work world-wide and can begin surveillance within 24 hours.

We sub-contract to a group of a multicultural team of 23 male and female operatives. They are a highly trained, ex government former team of operatives. Names, ranks and expertise are available on request to qualified clients.

Aside from the expertise of our team – individually and collectively as a group – we also take pride in the system we use when conducting surveillance services. We have developed a foolproof method of gathering evidence in a discreet and professional manner. This surveillance can be carried out discreetly or covertly, depending on your needs.
