Can a Private Investigator Run a Background Check on a New Client?

When you run a business, protecting your reputation and avoiding unnecessary risk is part of the job. Taking on new clients can be a big step, especially when high-value contracts or sensitive information are involved. So it’s no surprise that some business owners consider running background checks before making a commitment.
But can you bring in a private investigator to look into a potential client? Yes, you can. And in many cases, it’s the smart thing to do. That said, there are rules around how this should be done, and it’s important to understand the legal and ethical framework before moving forward.
Why might you want a background check on a client?
There are several good reasons to check up on a client before signing any paperwork or sharing sensitive information.
You might want to:
- Confirm their identity and business background
- Understand any financial or legal history that could impact your working relationship
- Spot any potential red flags early
- Comply with industry regulations or legal obligations
- Tailor your services based on what you learn
Whether you’re a consultant, contractor, trainer or part of a larger organisation, having a full picture of who you’re working with can make all the difference.
Is it legal for a private investigator to carry out these checks?
Yes, private investigators in the UK can legally carry out background checks, including those on prospective clients. But they must work within the boundaries of UK law, particularly when it comes to data protection. That means complying with the Data Protection Act 2018 and the UK GDPR.
In most cases, there needs to be a valid reason for gathering personal data. You may also need to secure the client’s consent, especially if the check involves accessing non-public or sensitive information. A professional investigator will be able to guide you through the correct process and help ensure everything is done above board.
What sort of information can be gathered?
Depending on your needs and what your client has agreed to, a private investigator might be able to check:
- Basic personal details such as full name, date of birth, and address history
- Employment history and professional qualifications
- Public business records and directorships
- Media coverage or legal proceedings
- Social media activity
- Verification of licences or certifications
Some information, such as criminal records or credit history, can only be accessed with the individual’s permission or under specific legal circumstances. A reputable investigator will make sure everything is handled properly and transparently.
What does the process look like?
When you decide to move ahead with a professional background check, here’s how the process usually goes:
- You have an initial chat with the investigator to explain your concerns and what you’re hoping to learn
- If needed, your client provides written consent
- The investigator collects relevant data using a variety of trusted methods
- Any findings are carefully verified for accuracy
- You receive a clear, confidential report
- If you have follow-up questions, the investigator can walk you through the results
Can you do it yourself?
There’s nothing stopping you from carrying out some of your own research. Online searches, checking Companies House, speaking to references or scanning social media are all useful. But these methods have limits. They won’t uncover hidden history or verify the full picture the way a professional can.
If you’re dealing with a high-value arrangement or you’ve already spotted warning signs, a proper investigation is usually the better route. It can help you avoid risk, protect your brand and make decisions with confidence.
Other steps you can take to protect your business
Background checks are useful, but they work best as part of a bigger approach. Here are a few tips for building a secure onboarding process:
- Develop a client intake checklist that includes basic screening
- Use clear agreements and waiver forms where relevant
- Communicate your terms and boundaries upfront
- Keep clear records of meetings, payments, and conversations
- Stay updated with any compliance changes relevant to your industry
When is it worth calling in a private investigator?
You might not need help with every client. But there are definitely situations where it’s worth considering:
- You’re entering a long-term or high-value agreement
- The client will have access to your systems, staff or sensitive data
- You’re taking on work that carries financial or reputational risk
- You’ve already picked up on a few things that don’t quite add up
