We’re here to make sure you feel as supported as possible, from your initial consultation to your final feedback. We have a professional but personable approach to our investigations to ensure our clients feel at ease.

CORPORATE INVESTIGATIONS IN THE CITY
Services for Businesses
London is internationally renowned as a city of commercial giants and the epicentre of global finance. London’s worldwide relevance shows no sign of relenting. Now more than ever, businesses in London need help to keep themselves protected from rogue employees and malicious competitors. Private Investigations UK offers investigative solutions to companies across London and The South.
Fraud and embezzlement threaten to bankrupt even the largest companies. Our fraud investigators can trace withheld assets and provide concrete proof of employee misconduct. We can also conduct thorough ID checks to prevent fraud as early as possible.
Before you welcome someone to your team, you should find out as much as you can. We call this enhanced due diligence. We offer EDD background checks to help you with the hiring process and as investment pre-screening. Get in touch with us to find out more about our different background checking packages.
Has your employer wrongly accused you of theft? Do you think your employee could be stealing from your business? We now offer lie detector tests to assist with internal investigations. Whatever your workplace dispute, we can conduct private polygraph tests to determine whether someone is telling the truth with a high degree of accuracy.
We can conduct the test here in our York Street office, in your office, or the privacy of your home. Find out more about polygraph tests.
CATCH OUT A CHEATING PARTNER
Uncovering Cheating
Our most popular services include our infidelity investigations. If you’re looking to catch your cheating husband or wife in the act, we can conduct covert surveillance to find out the truth. We always recommend that prospective clients check out our Signs of a Cheating Partner before beginning an infidelity investigation.
If you’ve spotted one or more common signs, we can likely get evidence of cheating. We understand this can be a difficult time, so we guarantee patient, professional, and empathetic service. Of course, we love empowering our clients with facts, but we also know how important it is that you feel supported every step of the way.
At PI UK, we believe that there’s a suitable investigation for everyone. We offer cost-effective solutions tailored to your budget, whatever your problem may be. To discuss your goals and the services we can provide, please give us a call for a friendly chat and a free consultation.
Responsible London Private Detective Agency
We love working in London. From Kensington to Bermondsey, we guarantee service across The Capital. From our feedback, we understand that many other London agencies don’t always take the time to listen to the client properly. We think that can seriously hamper your chances of success. After all, how can we ensure that we can get you the evidence you need if we don’t fully understand your goals?
We think the most critical part of a successful investigation is getting to know our clients. That’s why we offer everyone a free, no-obligation consultation of up to 30 minutes. We make ourselves available 24 hours a day, so we’re always available to chat, give you updates, and offer a shoulder to cry on if you need it.
PI UK values professional, respectful, and ethical investigations. We carefully vet all of our agents to ensure they’re of the highest standard. We don’t compromise on confidentiality, so we’ll never reveal details of your investigation to anyone unless you ask us to.
