About NIG

Since our formation in 1963 we have gained an enviable reputation as one of the oldest and most reputable investigation agencies in the UK. We have an international reach, and are known for our professionalism and discretion.

Over five successful decades

Our renowned level of service is based on the extremely high standards to which we adhere, and we believe the training of our staff, agents and representatives to high levels of proficiency is essential to our success.

For over five successful decades our services have been retained by wide- ranging and high-ranking individuals, from royalty and politicians, to celebrities. We have also worked extensively with international corporations, police forces, the press and broadcasting media, government departments and Local Authorities. Companies, firms, families and individuals use our services to receive effective solutions to their investigative requirements and are assured of absolute confidentiality, complete reliability and sensitive handling of their enquiries.
