Infidelity & Cheating Partner Investigations

You may suspect that your husband, wife, partner, or spouse is being unfaithful. 

Perhaps you’ve noticed troubling changes - the late nights, sudden weekend absences, unexplained trips, the guarded mobile phone, deleted messages, or sudden mood swings. 

These are common signs of a cheating husband or cheating wife, and while you may have tried to push the thoughts aside, the feeling that something isn’t right remains. 

When trust is in question, uncertainty can become unbearable - and finding the truth becomes essential.

At SJC Investigations, we specialise in covert infidelity investigations across the entire UK. 

We combine Level 4 trained covert surveillance expertise with discreet investigative techniques to uncover the facts - providing you with the clear, unbiased evidence you need to make informed decisions about your relationship.

• Nationwide Coverage: Whether you’re in London, Manchester, Birmingham, Cardiff, Edinburgh, or anywhere in between, our discreet operatives can deploy quickly and efficiently. Location is never an obstacle.
• Discreet, Unnoticed Surveillance: We use advanced covert methods to ensure your partner remains completely unaware they are being monitored.
• Budget-Friendly Solutions: We work to your budget, offering realistic and transparent pricing rather than inflated quotes.
• Experience in Sensitive Matters: Our lead investigator has handled countless relationship investigations, delivering results with professionalism and compassion.
• Clear, Court-Ready Evidence: Receive time-stamped photographs, video footage, and detailed reports that can be used in divorce proceedings or personal decision-making.

Our infidelity investigation services are tailored to your specific circumstances. This can include:

• Covert Surveillance – Monitoring your partner’s movements, interactions, and activities without detection.
• Vehicle Tracking (Case-by-Case Basis) – Providing location data to establish patterns of behaviour.
• Social Media & Online Activity Analysis – Identifying hidden profiles, unusual connections, or suspicious communication patterns.
• Background & Lifestyle Checks – Verifying whether your partner’s lifestyle matches what they have told you.
• Intelligence Gathering – Discreetly speaking to relevant contacts or witnesses where appropriate.

Every case is different, and our investigation plan will be tailored to your needs, your suspicions, and your budget.

1. Confidential Consultation – We listen to your concerns and gather details about your partner’s behaviour and routines.
2. Planning the Operation – Based on your information, we develop a discreet, cost-effective strategy to obtain proof
3. Covert Deployment – Our investigators carry out surveillance or other investigative techniques, ensuring complete confidentiality.
4. Evidence Delivery – You receive a full, time-stamped report with photographs and/or video footage, or a verbal briefing if you prefer.

Every case is different, and our investigation plan will be tailored to your needs, your suspicions, and your budget.

We provide professional surveillance across Buckinghamshire, Berkshire, Greater London, and surrounding areas.

Including High Wycombe, Princes Risborough, Aylesbury, Amersham, Chesham, Great Missenden, Beaconsfield, Gerrards Cross, Chalfont St Peter, Chalfont St Giles, Marlow, Henley-on-Thames, Slough, Taplow, Burnham, Maidenhead, Reading, Windsor, Uxbridge, Ruislip, Watford, and beyond.

This list is not exhaustive and location is never a barrier - wherever you are in the UK, SJC Investigations can deliver discreet, reliable surveillance. 

We combine expertise with advanced investigative techniques to ensure every operation is professional, thorough, and tailored to your needs.

Every infidelity case is different, so costs vary depending on the complexity and duration of the investigation. We work to your budget wherever possible, but as a guide, our minimum fee for covert surveillance is £300. This can include discreet monitoring of your husband, wife, or partner, detailed reporting, and photographic/video evidence. Larger or more complex investigations will be priced accordingly after a confidential consultation.

No - not if the investigation is conducted by experienced professionals. At SJC Investigations, we pride ourselves on absolute discretion. Our cheating partner investigations leave no digital footprint, and we never make contact with your spouse or their associates unless it is a planned part of the operation.

This depends entirely on the nature of your case. Some cheating husband or wife investigations can be completed in a single evening, while others may require ongoing surveillance over several days or weeks to establish patterns of behaviour. We will always advise you on the most efficient and cost-effective approach.

You will receive a comprehensive, time-stamped report, complete with high-resolution photographs and video footage where possible. This evidence can be used for personal closure or in divorce proceedings to prove adultery or unreasonable behaviour. If you prefer, we can provide a verbal report only to maintain your privacy.

Simply contact us for a free, confidential consultation. We’ll listen to your concerns, outline your options, and provide a clear action plan.

While suspicion isn’t proof, some common behaviours of unfaithful partners include:

• Being overly protective of their phone or social media accounts.
• Sudden changes in work patterns or unexplained absences.
• Increased attention to appearance and grooming.
• Becoming emotionally distant or irritable.
• Unexplained charges on bank or credit card statements.

If you recognise several of these signs, a UK cheating partner private investigator can help you find answers.

Infidelity investigations are often sought by individuals who suspect a partner may be hiding the truth and need clear, reliable evidence before making important personal decisions. 

Our discreet methods provide clarity and reassurance in highly sensitive situations.

In some cases, surveillance plays a key role in gathering evidence of a partner’s activities, while background checks can uncover hidden connections or undisclosed information. 

Our additional investigations can provide further support depending on the circumstances.

Our approach is always discreet, professional, and evidence-based, giving clients the information they need to move forward with confidence.

Your Privacy is Our Priority

We understand how emotionally charged infidelity cases can be. Everything you tell us is treated with the utmost discretion. Our work leaves no digital footprint, ensuring there is no risk of your partner discovering the investigation.

Why Acting Quickly Matters

In our experience, delays often allow a cheating partner to cover their tracks or alter their behaviour. The sooner we can begin, the greater the chance of securing clear, undeniable evidence.

Nationwide Infidelity Investigations

We have successfully assisted clients from all over the UK - from London, Birmingham, and Manchester to Glasgow, Cardiff, and Belfast – as well as smaller towns and rural areas. Our nationwide network ensures rapid response and complete discretion wherever you are.
