“We used Deception Detection UK for an internal fraud investigation. The P300 EEG approach felt far more robust than a polygraph and the final report stood up to legal scrutiny. Communication was excellent throughout.”
“We had a long‑running family dispute where nobody trusted anyone’s version of events. The P300 EEG testing gave us objective results that everyone could agree on. It finally ended years of arguments.”
“Booked a same‑day P300 EEG test after discovering messages on my partner’s phone. It was an awful day but the staff were compassionate and non‑judgemental. I had an initial result before leaving and a full report the next day.”
“For months I had a gut feeling something was wrong. The P300 test confirmed my partner had been unfaithful. It was painful, but at least I finally had proof and could stop doubting myself.”
“I was being accused of cheating and it was destroying our relationship. The P300 EEG test showed I was telling the truth. It helped rebuild trust and stopped the constant arguments.”
“The process was thorough and professional. The results confirmed my partner had been lying about messages and hotel stays. I wish I’d done it sooner instead of living in constant doubt.”
“I was terrified the test would say I’d cheated when I hadn’t. The team explained everything clearly and the result showed I was truthful. It gave my partner the reassurance they needed.”
“The P300 test confirmed my husband had been having an affair he kept denying. It was heartbreaking but at least I could stop being gas‑lit and make decisions based on facts not lies.”
“My partner insisted that explicit chats online ‘didn’t count’. The questions were tailored around what we considered cheating and the results made it impossible for him to keep minimising it.”
“We had been through cheating once before and I swore never again. When my doubts came back, the P300 test showed fresh deception. It gave me the strength to finally walk away.”
“We live in different cities and were both paranoid. We both did the test. It showed neither of us had cheated and took a huge weight off our shoulders.”
“Before getting engaged we wanted to clear the air about previous accusations. The testing gave us both confidence to move forward without hidden doubts.”
“Money kept going missing from my mum’s house and everyone was blaming each other. The P300 tests helped show who was telling the truth and stopped the constant accusations at every family gathering.”
“We suspected one sibling had been taking items to sell. The testing didn’t magically fix the relationship, but it provided clarity and helped us protect our vulnerable parent.”
“We used P300 testing as part of a wider dispute over missing jewellery after a relative died. It helped confirm who had knowledge of the items and narrowed down the conversations we needed to have.”
“Our teenager kept denying taking money from wallets. The test showed deception around specific incidents, which finally brought the issue into the open and allowed us to get help.”
“We suspected a relative staying in a family home was taking small amounts of cash from an elderly parent. The testing helped confirm our concerns and we were able to put proper safeguards in place.”
“We were losing stock every month and couldn’t identify who was responsible. The P300 tests helped narrow down the issue and supported disciplinary action alongside our own evidence.”
“Persistent till shortages were causing distrust among staff. Using P300 testing as part of the investigation helped us clear some staff completely and focus on where the problem really was.”
“Tools were going missing from the site and the atmosphere was getting toxic. The P300 tests supported our internal investigation and helped us put a stop to it.”
“We used P300 EEG as part of an investigation into missing bar takings. It won’t replace proper controls but it did help establish who was and wasn’t involved.”
“My partner insisted the relationship with a colleague was ‘just friendship’. The questions were written around emotional boundaries, and the results showed he hadn’t been honest about what had happened.”
“We agreed not to use dating apps but I kept finding evidence he’d installed and deleted them. The P300 test included specific questions about using apps behind my back. It stopped the endless denial.”
“Unexplained weekends away were becoming a pattern. The test focused on those trips and the people involved. It confirmed my worst fears but also stopped me questioning my own sanity.”
“We agreed some rules after past cheating. The P300 test focused on whether those boundaries had been broken again. Getting a truthful ‘no’ result helped us move on.”

“We used Deception Detection UK as part of our due‑diligence checks for a sensitive franchise partnership. Their experience with corporate and legal environments made the process straightforward.”

“We chose to do testing before getting married to put old issues to bed. Unusual maybe, but it helped us both feel we were going into the marriage with nothing hidden.”
“As a professional who occasionally recommends specialist testing, I need providers who are honest about the limits of what they do. Deception Detection UK are clear, transparent and evidence‑driven.”
“I suffer from anxiety and was worried this would affect the test. They took time to explain that P300 EEG is not about heart rate or sweating, which helped me feel calmer and more in control.”
