Catch a Cheating Partner in the UK

Suspecting your partner of cheating is a horrible position to be in. Whether it’s a change in behaviour, hidden messages, or just a gut feeling — if something doesn’t feel right, there’s often a reason. You don’t have to sit in the dark wondering. We specialise in infidelity investigations across the UK, helping clients discreetly find out the truth and gather solid evidence of unfaithfulness when needed.

We’ve helped thousands of clients catch cheating partners throughout England, Scotland, Wales, and Northern Ireland. Our operatives are experienced, discreet, and legally trained to conduct surveillance, use GPS tracking devices, and perform background checks to uncover the truth while protecting your privacy.

How to Tell If Your Partner Might Be Cheating

Here are some common red flags that might suggest infidelity:

• They’ve suddenly become secretive about their phone, social media or whereabouts
• Unexplained changes in routine — late nights, new hobbies, more 'work trips'
• A noticeable change in physical appearance, grooming or fitness
• Less intimacy, more arguments, or emotional distance
• Mysterious expenses showing on bank statements or credit cards

One sign alone may mean nothing. But if you’re seeing several of these, it might be time to act.

Why You Might Need Proof of Cheating

Sometimes you need peace of mind. Other times, you need proof — whether it’s for your own closure, to support divorce proceedings, or to confront your partner with undeniable evidence.

According to YouGov, one in five British adults admit to having had an affair. That’s a lot of people lying to someone who trusts them.

It's important to act sensibly and legally when trying to find out the truth. Emotions run high, but acting rashly or trying to gather evidence yourself could damage your case, alert your partner, or even land you in legal trouble. That's why so many people in the UK turn to licensed private investigators — not just for the results, but for peace of mind that everything is being handled correctly and confidentially.

How We Catch Cheating Partners

We use a combination of tactics depending on your situation. The goal is always the same — to gather clear, legal evidence while staying completely under the radar.

Surveillance

Our most common tool. We’ll follow your partner discreetly and document where they go and who they’re with. This usually results in video or photo evidence which you’ll receive in a secure report. Visit our surveillance page for more information.

Honeytrap Investigations

If you’d like to test your partner’s loyalty directly, we offer honeytrap services where one of our decoys approaches them in real life or online to see how they respond. It's quick and effective — often revealing whether someone is open to cheating, or not.

GPS Vehicle Tracking

If your partner drives a car you own or have legal access to, we can discreetly install a GPS tracker to monitor their movements. This is often paired with surveillance so we know exactly when and where to follow them. The combination gives us better efficiency and helps reduce the number of hours spent on the ground.

Background Checks

Sometimes it’s not about catching someone cheating — it’s about making sure the person you’re with is who they say they are. We offer background checks that are ideal for looking into someone new in your life, or in the life of someone close to you. Whether you're just starting a relationship or something feels off, we can discreetly dig into their history and uncover anything they might be hiding.

These checks often include open-source intelligence (OSINT) research — meaning we search for publicly available data that might not be obvious to the average person. For example, we might identify whether someone has appeared in court recently, has been mentioned in a local news article for criminal activity, or has a questionable online footprint. If you're worried you’re being scammed by someone you've met online, or just want to be sure someone isn’t lying about their past, these investigations can be invaluable.
