Grievance and Disciplinary Investigation Service

We undertake fair, robust and proportionate investigations into any type of grievance, disciplinary or whistleblowing complaint. Our professional investigation service means that whether you want to outsource one complaint, or to contract your whole investigation needs to CMP, you are working with the UK’s leading provider of workplace investigations. 

We can help you achieve a sensitive, thorough and independent investigation into complaints of bullying or harassment when you and your colleagues are snowed under with vital time-limited work, or you don’t have someone suitable to deal with a sensitive or senior-level complaint. We can be on site within 5 days, and will complete the investigation within 30 days.  

We are the only organisation in the UK which is clear about the practice standards we work to.  It is our 20 years’ experience and our team of professional investigators working on over 200 investigations per year that makes us the investigation experts.

No matter what your organisational culture, or the status of the parties involved, we will have the investigator to fit your needs. Our team is an outstanding and diverse team of specialists: HR, lawyers, barristers, former union reps, magistrates, and Acas officials.   And because you’re working with the UK’s largest provider of independent workplace investigations, we make sure your investigations are carried out within 30 days, delivered to budget, and will stand up to the most rigorous ET scrutiny.
