Private Investigation Services

Relationship, Matrimonial & Partner Investigations

You may have noticed a change in your partner’s routine, unexplained absences, conflicting stories, unusual secrecy or spending that does not make sense. You may instead be considering marriage, moving in together or sharing money with someone whose background you do not fully know. These situations are personal and often upsetting. Our role is to establish facts discreetly, without judgement or unnecessary drama.

Our cheating partner investigations in London cover matrimonial infidelity investigation, matrimonial surveillance, possible cohabitation, divorce-related enquiries, partner background checks, pre-marital checks and online-dating concerns. You do not need to decide which label fits your situation before contacting us.

When surveillance may help

Covert surveillance in London can help when there is a particular time, journey, address or pattern of behaviour that needs to be checked. Examples include regular unexplained late finishes, a suspected overnight stay, a known event, or a partner who says they are in one place when you believe they may be somewhere else.

We do not recommend watching someone for days without a clear reason. We talk through the routine with you and identify the times most likely to answer your question. This keeps the investigation focused and helps control cost.

What our investigators do during surveillance

An investigator observes from public places and records relevant movements, meetings and locations. Where it is legal and practical, photographs or video may be taken. The investigator keeps a timed record of what happens and does not approach or confront your partner.

Some jobs can be handled by one investigator. Others may need two or more, especially if the person travels by car and public transport, uses several exits, or is likely to notice the same vehicle. We explain why additional investigators may be needed before you agree to the work.

Infidelity and unexplained behaviour

Surveillance may show who your partner meets, where they go and how long they remain there during the agreed period. It cannot tell us what two people say in private or what they feel. If nothing relevant happens, that is reported honestly. One quiet day does not prove that nothing has ever happened, just as one meeting does not automatically explain the nature of a relationship.

Cohabitation and separation enquiries

If the question is whether someone may be living with another person, one overnight stay is rarely enough. A useful investigation may look for a repeated pattern such as overnight presence, morning departures, vehicles regularly kept at the address and everyday domestic activity. We record the pattern we observe; your solicitor decides what it may mean for a legal or financial matter.

Checking a new or existing partner’s background

Before marriage, shared finances or another major commitment, you may want to check important claims about a person’s identity, address history, employment, businesses or public background. We agree the specific questions with you rather than searching for irrelevant personal information.

A background investigation may compare names, addresses, companies, public records, news reports and information the person has made publicly available online. We do not access private accounts, private messages, bank accounts or protected government records.

Online dating and romance-scam concerns

Warning signs can include refusing video calls, stories that keep changing, photographs linked to other names, repeated emergencies, requests for secrecy or pressure to send money, cryptocurrency or gift cards. We can check whether the person’s identity and story are consistent with information that is legally available.

If you are being asked for money now, pause the payment and contact your bank. If money has already been lost, you may also need to report the matter to the police, Action Fraud or the relevant platform. Do not wait for an investigation before protecting your finances.

Your surveillance or background report

For surveillance, you receive a clear timeline with relevant photographs or video. A background report explains what was confirmed, what appears inconsistent and what could not be checked. If both services are used, the findings appear in one report that you can share with your solicitor where appropriate.

Pricing

Surveillance is from £520 + VAT per operative for a standard deployment of up to 8 hours. Additional time after 8 hours is charged from £65 + VAT per hour, per operative, or at the hourly rate agreed in writing before deployment. Short-duration, tightly defined assignments are quoted individually. Partner background, pre-marital and online-dating investigations start from £550 + VAT. Wider divorce or separation investigations start from £750 + VAT.

Most Popular Questions

Frequently Asked Questions

Will my partner know I contacted you?

Your enquiry is confidential. Surveillance is planned to reduce the chance of being noticed, although no investigator can promise that the risk is zero.

Can you prove infidelity in one day?

Sometimes a single observation answers a narrow question, but often it does not. We explain what the chosen date can realistically show before you book.

Can you read private messages or dating accounts?

No. We do not hack accounts, use stolen passwords or intercept private communications.

What if the investigation finds nothing?

You receive an honest report of the agreed period. We explain whether another date may add useful information, without pressuring you to continue.

Ready to discuss your case in confidence?
