Employee Theft Investigation
“Stock, cash or takings are going missing. You may already suspect who. What you do not have yet is proof you can safely act on.”
Employee theft investigation establishes what has been taken, over what period, and by whom. Most employers reach this point with a strong suspicion and no usable proof, which is the worst position to act from: moving too early risks an unfair dismissal claim, and doing nothing lets the loss continue. A structured investigation replaces suspicion with evidence you can act on either way.
What We Do
Establishing The Loss
Quantifying what has actually gone, over what period, through stock, till, delivery and transaction records.
Identifying Responsibility
Narrowing from a loss to a person through pattern analysis and, where justified, discreet observation.
Evidence For Action
Findings documented so a disciplinary, a civil claim or a police referral can proceed on solid ground.

Our Process
- 01
Confidential brief

Evidence & report
You receive a documented account your HR team, solicitors or the police can act on.
Why ASE
Fair Process Protected
Evidence gathered so a dismissal rests on a reasonable investigation, reducing the risk of a tribunal claim later.
Nothing Tipped Off
Enquiries run without the individual or their colleagues knowing, which preserves both the evidence and workplace calm.
Innocence Matters Too
A proper investigation is as valuable when it clears someone. We report what the evidence shows, not what was suspected.
Proportionate Method
Records work first, observation only where it is justified by what the records show.
Frequently Asked Questions
What should I do if I suspect an employee is stealing?+
Act carefully and slowly. Do not confront the individual, do not discuss it around the workplace, and do not start deleting or reorganising records. Preserve what you already have, including CCTV before it overwrites, and take advice before doing anything the person could notice.
How do you prove employee theft?+
By connecting a documented loss to a specific person through more than one independent source: transaction and stock records showing when losses occur, access or rota records showing who was present, and where justified, observation. A single suspicious record is rarely enough on its own.
Can I dismiss an employee for theft without hard evidence?+
UK employment law does not require proof to a criminal standard, but it does require a genuine belief in the misconduct, reasonable grounds for that belief, and a reasonable investigation before the decision. Acting on suspicion alone is what leads to successful unfair dismissal claims, which is exactly what a proper investigation prevents.
How long does an employee theft investigation take?+
The records analysis is usually quick. If observation is needed, it has to run long enough to be representative rather than a single snapshot. We give you a realistic timeframe once we know what is going missing and how often.
Should I involve the police?+
That is your decision, and it is often easier once you have documented evidence rather than a suspicion. Many employers deal with the matter internally through a disciplinary process and pursue recovery civilly. We prepare findings so either route stays open to you.
