Outsourced Investigation Services that you can rely on.


There are many reasons that organisations choose to outsource their investigations to The Investigation Company. There may be an especially complex case; a lack of available internal resources; or simply a desire to apply a consistent approach and the highest quality standards.

Whatever the reason, there are countless benefits to outsourcing a case. Not only do we offer the highest degrees of independence and impartiality, but we are also perceived as such by the parties involved. This is equally important. Our investigators are able to prioritise your case, free from other distractions, to ensure that the case is conducted in a timely manner, without unnecessary delays.



Every case that we deliver is conducted in line with the ACAS ‘Conducting workplace investigations’ guidance and British Standards Institute BS1020002018 code of practice for the provision of investigative services.

This quality assurance ensures that the process can withstand the highest levels of scrutiny, for minimal risk of failure at any subsequent employment tribunal or appeal.


The collective background and expertise shared by our team of investigators is unrivalled. They are competently trained and highly experienced in investigating a full range of typical misconduct issues, alongside the more common allegations of bullying, harassment and discrimination.

Most issues we encounter relate to grievances or general misconduct; however, we are also the experts in responding to the most complex and serious allegations.

Thanks to our investigators’ varied professional backgrounds we are also equipped to investigate:

  • Fraud, Bribery & Corruption
  • Regulatory/ Ombudsman Complaints
  • Compliance, Ethics and Professional Standards Issues
  • Multiple/ Complex Allegations

Whatever the issue, our investigations are conducted to world-class standards, with a sensitive approach that places people at the centre of the process, while maintaining objectivity.

The risks of getting an investigation wrong are significant. At an appeal or Employment tribunal, procedural failings can be used to undermine the action taken by the employer. Failure to investigate properly and reasonably is one of the most common causes of loss at the tribunal stage.

How do employers get it wrong?

Throughout our extensive experience, we’ve encountered a range of factors involved, when an investigation goes wrong. Some of the most common failings we come across include:

  • Using poorly trained, or untrained investigators
  • A lack of planning or unclear terms of reference
  • Delays in the process
  • Poorly written reports

…it really doesn’t have to be this way.

The Benefits of Outsourcing:

There are a number of factors which make outsourcing your case to The Investigation Company the best choice. Here are just a few of them:

  • Independence and Impartiality: Our investigators are completely impartial, with no prior knowledge of the parties involved, they will have absolutely zero vested interest in the outcome of the process.
  • Credibility, Experience & Expertise: All of our investigators are highly experienced. They are also skilled in the very latest evidence handling and interviewing techniques, ensuring for a thorough, fair and objective process.
  • Risk Mitigation: Far too often we hear reports of compensation or penalties at tribunal claims or appeals where action has been taken without a fair investigation. Work with us to ensure that a poorly followed process doesn’t come back to haunt you.
  • Free Up Your Internal Resource: HR staff and managers have a lot of priorities to juggle. Not only does an investigation add additional stress, but they take up time that isn’t always available. Our pool of investigators are able to conduct their casework with minimal distraction and delay, saving time and stress for all involved.
  • For Practical Guidance: Investigations aren’t always the right response. Our team of experts will hold an initial discussion to understand the specific nature of the issue, and can advise whether an alternative approach may be better suited. We only investigate when we need to do so.


Based on our experience in conducting investigations with organisations from all industries, we have developed a unique ‘TRIAGE’ system to ensure that every case we deliver is conducted in an independent, objective, robust and comprehensive manner.

The ‘TRIAGE’ system outlines the 6 key stages of our investigative process:

  1. The Terms of Reference: Outlining what is to be investigated, providing a clear remit for the process.
  2. Review: The assigned investigator will review all relevant documentation, including the initial complaint, relevant policies/ procedures, and additional evidence.
  3. Interview: An open and safe environment is created to gather evidence from the complainant(s), respondent(s) and any identified witnesses.
  4. Analysis: All evidence is carefully assessed to determine if any further information is needed.
  5. Gathering: Additional evidence, such as CCTV footage, email exchanges, and policies are gathered in a timely manner to avoid unnecessary delays.
  6. Evaluate: Once all information has been compiled, the investigator will draw their conclusions based on the ‘balance of probabilities’.
