About us

A1 Investigations Bureau Ltd has operated locally, nationally and internationally for over 30 years. We are a family business which prides itself in ensuring that our customers find peace of mind through the services we offer.

The truth is out there, It’s time to investigate.

A1 Investigations Bureau Ltd

Due to the nature of the work A1 Investigations does, we are naturally discreet so please excuse the lack of finer detail such as names. But that doesn’t mean we can’t share a little bit of history about us. Investigation work has been in the family across many previous generations – so you could say it is in our genes. We started life as Wrexham and Clwyd Investigations in 1988 and quickly became a trusted and respected investigation agency with numerous offices across North Wales and the North West of England, offering a variety of private investigation services. As we grew and the demand for services like ours changed and evolved, we brought everything together into one new business name: A1 Investigations Bureau. It was at this point that our services started to expand outside of the north-west to a national and then international level.

We have a very strong ethos here at A1. For us, investigation work is not about making a fortune, it never will be. It is about finding answers for people facing challenges, giving them peace of mind, and supporting them to get the facts they need to help them move forward with their lives.

At A1 we are all about finding the facts and getting answers for our clients, keeping them ahead of a situation both financially and factually.

Tracing a bad debtor
