One of the UK’s leading private investigation agencies
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 Ltd.
