Common questions
Frequently Asked Questions
How much does a private investigator cost in the UK?
Close
Costs depend on the case type and complexity. Surveillance is charged at 295 pounds per operative per day, with a discounted daily rate when three or more days are instructed. People tracing is a fixed fee of 120 pounds per trace and background checks start from 195 pounds. We provide a free, no-obligation quote after your consultation so you know exactly what to expect.
Are your investigators licensed and accredited?
Open
Yes. All UKPI operatives hold relevant professional accreditations and follow strict codes of conduct. We are members of recognised industry bodies and our evidence-gathering methods meet the standards required for court proceedings.
Is everything I tell you confidential?
Open
Absolutely. Every enquiry, conversation, and piece of evidence is treated with the strictest confidence. We never share your information with anyone without your explicit written consent.
How quickly can you start an investigation?
Open
In most cases we can begin within 24 to 48 hours of your initial consultation. For urgent matters, same-day deployment is often possible depending on your location and the type of investigation.
Will the person I am investigating find out?
Open
Discretion is at the heart of everything we do. Our investigators are trained in covert techniques and we take every precaution to ensure the subject is unaware of the investigation. In 29 years of operations, our methods have never been compromised.
Can your evidence be used in court?
Open
Yes. All evidence we gather is collected lawfully and documented to the standard required by UK courts. We regularly provide evidence for family law, employment, and civil proceedings, and our reports have been accepted by courts across England and Wales.
