Our Assurances, Reputation & Accreditations



As a leader in private investigation services, Global Investigations’ team of highly skilled private detectives are trained to carry out services to suit the needs of you, the client, bringing the situation to a rapid conclusion and giving you the answers you need.

The private investigations industry in the UK is one where Global Investigation are an advocate of encouraging licensing within the industry. Unfortunately this is not yet been accepted in the UK courts, however we hope this will soon be implemented in the US, raising the standards of every private detective agency.

Currently, we have taken on self-regulation by being upstanding members of the ABI where our main investigators undergo a financial and criminal check and the company proud to be working within the bound of the ABI code. We also have also opted to be a member of the British Standard (BS10900) where the company is checked yearly with the standards board.

In nearby Ireland, where they do have regulation enforced for the investigations sector, we are registered through The Private Security Authority (PSA registration number 08776).
