How can working with an expert workplace investigation company help?

Carrying out investigations in the workplace is necessary, regardless of your business size or nature. Investigations often involve tangles of claims and counter-claims, sometimes involving the senior team. When encountering these, organisations need to demonstrate the highest levels of professionalism. Increasingly the world is watching and conducting an improper investigation leaves open the risk of potential liability and highly negative consequences.

CMP has been carrying out workplace investigations on behalf of employers for 30 years. Such experience includes compliance and whistleblowing issues, complaints and grievances, bullying and harassment, and more. Our experience has made us the UK’s leading provider. We have an established network of highly experienced workplace investigators, based in locations across the UK. All are expertly trained in delivering a fair, robust, and quality service in line with legislation, best practice, and the British Standard for Investigation Services BS:102000.


If a complex workplace investigation is left to inexperienced managers, the chances of success are greatly reduced. The likelihood of an employment tribunal becomes increased. In such situations, the costs to the business and impacts on staff members can rapidly escalate. This has a huge impact on productivity.

Workplace investigations can often involve sensitive and complex situations. In such cases, employees may find it difficult to address difficult matters in the presence of a familiar colleague. We find that participants are often reassured when using an independent external investigator and can better open up and express their concerns. It’s critically important to obtain all valuable information during an investigation. CMP’s workplace investigators are in the best possible position to achieve this.

Contracted Workplace Investigation Services

When taking out a contract for investigation services with CMP, you’ll receive a favourable rate with flexible options. You’ll then be able to simply pick up the phone and we’ll assign an investigator to you, who will prioritise your case.

Involving independent investigators means reducing the risk of mishandled cases and reliance on senior managers and HR for time-consuming tasks. This is something that particularly should be avoided during times of major organisational change. The CMP approach to internal investigations is regulated to consistent standards and processes.

CMP Investigators have expert knowledge of the process of investigation in the workplace. They’re able to encourage more trust and willingness to participate among employees. This allows for a resolution to be reached more quickly. Critically, when working with us to investigate workplace matters, you’ll limit the potential for failure at appeals. The risk of claims being escalated into formal employment tribunals is also greatly reduced.
