Trusted by UK Employers
Discretion means we anonymise client names, but here is what they have said.
Horizon proved a senior employee was running a competing business on company time. The evidence pack made a contested dismissal completely defensible at tribunal.
We had been losing £40k a year in stock shrinkage. The Horizon team identified the culprits within ten days. Polite, professional and completely invisible.
An employee claimed they were too injured to work. Horizon delivered hours of footage of them playing five-a-side football. Saved us a six-figure claim.
Employee Investigations FAQs
Is it legal to investigate an employee in the UK?
