Suspecting your partner of infidelity can be one of the most distressing experiences in a relationship. Whether you are looking for peace of mind, seeking evidence during divorce proceedings, or simply want answers, hiring a professional private investigator can help establish the facts.
At Surelock, we have over 25 years of experience conducting discreet and professional surveillance operations across the UK. Our experienced investigators understand the sensitive nature of these cases and work with complete confidentiality to provide reliable evidence.
Choosing a Professional Private Investigation Company
When hiring a private investigator, it is essential to choose a reputable company with proven experience and recognised professional standards.
Surelock is committed to delivering the highest level of service. We recommend using investigators who are members of recognised industry organisations, such as the Association of British Investigators.
Working with an accredited company provides reassurance that your investigation will be handled professionally, ethically, and within the law.
Our Professional Surveillance Services
Surveillance is one of Surelock's core services. We provide a range of specialist surveillance solutions, including:
- Corporate Surveillance
- Investigative Surveillance
- Accident Injury Surveillance
- Domestic / Cheating Partner Surveillance
Domestic and Cheating Partner Surveillance
Our domestic surveillance services are designed to establish the facts surrounding suspected infidelity.
Before any investigation begins, we discuss your concerns in detail so you fully understand the process, costs, and likely outcomes.
With over two decades of experience, our nationwide surveillance teams include highly trained professionals with police and military backgrounds, enabling us to gather evidence discreetly and effectively.
What Can Surveillance Reveal?
Every investigation is different, but our objective is to establish whether there is evidence of:
- An ongoing affair
- A one-night encounter
- A long-term relationship
- Cohabitation with another partner
- In some cases, an entirely separate family life
Frequently Asked Questions
Many clients contact us feeling anxious and unsure of what is legally possible. We are often asked questions such as:
1. Can you track someone's mobile phone?
No.
2. Can you monitor someone's messages?
No.
3. Can you put a tracker on their vehicle?
For domestic investigations, the answer is no. These methods are either unethical, unlawful, or both.
While vehicle trackers may occasionally be used as part of certain criminal investigations alongside physical surveillance, they are not used for cheating partner investigations.
The Only Legal Way to Confirm Infidelity
Professional surveillance remains the most reliable and lawful method of establishing whether someone is cheating.
As the saying goes: "The camera never lies, every picture tells a story."
How the Investigation Begins
Every case starts with a confidential conversation.
We take time to understand why you suspect your partner may be unfaithful and discuss the circumstances surrounding your concerns.
Rather than recommending unnecessary surveillance that could become extremely expensive, we advise focusing on specific dates, routines, or suspicious events where evidence is most likely to be obtained.
Our aim is always to provide the best possible service rather than simply charging for surveillance that may not produce results.
What Information Do We Need?
To begin an investigation, we usually require:
- A recent photograph (if available)
- A physical description
- Vehicle details
- Home address
- Dates or events when suspicious behaviour is most likely
This information enables our surveillance team to prepare effectively and maximise the chances of gathering evidence.
What Happens During Surveillance?
For every domestic surveillance operation, Surelock deploys a minimum three-person surveillance team.
Unlike one-person operations, a three-person team significantly increases the likelihood of maintaining uninterrupted observation while remaining discreet.
During surveillance, investigators:
- Follow the subject throughout the day
- Record movements and meetings
- Capture video and photographic evidence
- Compile a detailed timeline of events
- Gather intelligence suitable for personal or legal use
Where appropriate, we also keep clients informed throughout the operation via WhatsApp updates.
Following the investigation, clients receive:
- A detailed surveillance report
- Selected photographs
- Video evidence
- An unedited recording where applicable
Is Domestic Surveillance Legal?
Yes.
All Surelock surveillance is conducted lawfully in public places.
Our investigators work in accordance with the principles of the Regulation of Investigatory Powers Act 2000 (RIPA).
Although private investigation companies are not directly governed by RIPA, Surelock voluntarily follows its guidance to ensure all surveillance is carried out professionally and ethically.
What Happens After the Investigation?
Once the evidence has been delivered, we carefully discuss our findings with the client.
Where infidelity has been confirmed, we always recommend approaching the situation with caution to avoid confrontation or escalation.
Depending on your circumstances, seeking independent legal advice may also be appropriate.
How Much Does Cheating Partner Surveillance Cost?
Surelock operates a transparent hourly pricing structure.
Surveillance is charged at £60 per hour, per operative.
A typical three-person surveillance team working an eight-hour day costs approximately £1,500, plus travel expenses and VAT.
While some companies advertise one-person surveillance, we believe this is rarely sufficient for professional investigations. Using a dedicated three-person team allows us to deliver the highest standard of evidence without compromising the investigation.
