Private Investigator in Brighton

Updated 1 August 2026 by K3K Investigations

Brighton is a city where cars are a liability — narrow Regency streets, permit parking, the Lanes' pedestrian maze — and where half the working population's week is split between the seafront and a London train. K3K runs surveillance, matrimonial, corporate and cyber casework across Brighton & Hove and Sussex, under an hour from our London base, with methods suited to a city best worked on foot.

Brighton's casework mirrors its economy and its geography. A digital and creative sector produces the corporate instructions of a tech town — departing staff taking clients and code, contractor moonlighting, due diligence on founders and agencies. The commuter artery to London Bridge and Victoria means routines split across two cities, which matrimonial casework has to cover at both ends. And a visitor economy of conferences, stags and weekends provides endless natural cover for surveillance — and endless natural cover for the behaviour that gets investigated. Every case: London-run, evidence to court standard.

Covert surveillance in Brighton

Our surveillance teams work Brighton the way it moves: on foot through the Lanes, North Laine and the seafront where crowds give cover in both directions; on the trains, where a London-commuting subject's real day happens; and by vehicle only where the A23/A27 and the suburbs make it sensible. Hove's residential avenues and permit zones need positioning chosen in advance, not improvised. Timestamped video, disciplined logs, admissible.

Matrimonial casework in a two-city life

The Brighton pattern our matrimonial team sees most: a relationship lived in Brighton, a working week lived in London, and a truth that only appears when both are covered. We run coordinated coverage at each end — something a genuinely London-based agency with Brighton fieldcraft does better than either a local one-man band or a capital firm that treats Brighton as an away day.

Corporate and cyber investigations

For the digital quarter: corporate investigations into IP and client-list exfiltration, due diligence on agencies, founders and investors, workplace cases handled to tribunal standard — and, where the harm arrived online, cyber investigations into harassment, fraud and impersonation, a caseload Brighton's creative economy generates steadily.

People tracing across Sussex

Our tracing desk covers Brighton & Hove, the coastal strip from Worthing to Eastbourne, and the commuter towns up the A23 — debtors, missing family, beneficiaries, and the high-churn rental population a seaside city turns over every year. No-trace, no-fee options on most standard traces.

Frequently asked questions

My partner commutes to London — can you cover both ends?

Yes, and that dual coverage is usually the case. We coordinate teams across the commute itself, the London working day and the Brighton evening — one operation, one report, no gaps for the truth to hide in.

Is Brighton's crowd cover good or bad for surveillance?

Good for us, bad for amateurs. Crowds let a foot team work close without exposure, but they punish operatives who can't move naturally in them. Seafront, station and Lanes work is a foot-surveillance discipline — exactly what our teams train for.
