Understanding retail shrinkage and its impact
What is Retail Shrinkage?
Retail shrinkage refers to the loss of stock or profit due to causes other than legitimate sales. It’s a major concern in the UK retail sector, costing businesses billions annually.
Shrinkage = Stock Loss
Formula:
Total stock loss = (Recorded inventory – Actual inventory)
Shrinkage can be caused by:
Shoplifting (External Theft)
Employee Theft (Internal Theft)
Administrative Errors
Supplier Fraud
Damage or Spoilage
Why Does Shrinkage Matter in Retail Security?
As a licenced security officer or store detective, your role is directly linked to reducing shrinkage. Shrinkage affects:
Retail prices – More theft leads to higher prices for honest customers.
Store profits – Businesses can suffer serious losses.
Job security – Increased shrinkage can result in job cuts or store closures.

Shoplifting remains the leading cause, followed by employee theft.
Supermarkets and high street fashion outlets are among the most affected sectors.
Legal Framework You Must Understand
SIA Licencing – Private Security Industry Act 2001
You must hold a valid SIA licence to work in a retail security or store detective role. It ensures you are vetted and trained to professional standards.
Theft Act 1968
Defines theft, shoplifting, handling stolen goods, and related offences.
Key Point: Attempted theft is also an offence.
Criminal Law Act 1967 – Reasonable Force
Allows “any person” to use reasonable force to prevent a crime or detain an offender until police arrive (citizen’s arrest).
Human Rights Act 1998
You must protect the rights of the public — including dignity, privacy, and non-discrimination — even when dealing with suspected offenders.

Your Role in Shrinkage Prevention
As a retail security officer or store detective, you:
Patrol store floors discreetly
Monitor CCTV systems
Observe suspicious behaviour using ASCONE
Liaise with store managers and police

Real-World Example
Scenario:
You’re stationed in a high-street sportswear store. You notice a customer behaving nervously near the changing room. Following the SAFER model, you:
Step back
Assess the situation
Find help (e.g., radio to a colleague)
Evaluate (watch if ASCONE is fulfilled)
Respond (only if confirmed — e.g., exiting without paying)
By following protocol, you prevent false accusations, stay compliant, and reduce shrinkage safely.
Industry Standards You Must Follow
| Standard | What It Requires |
|---|---|
| BS 7499 (Static Site Guarding) | Sets professional standards for uniformed guarding, patrols, and retail security duties. |
| BS 7858 (Screening/Vetting) | Ensures you are properly background-checked for working in trust-sensitive roles. |
| NSI Codes of Practice | Promotes quality, integrity, and professionalism in security work. |
| ISO 9001 | Relevant in larger operations; ensures quality management systems are in place to reduce loss. |
Consequences of Poor Shrinkage Control
If shrinkage is not addressed, it can lead to:
Loss of SIA licence (if procedures are breached)
Police investigations for misconduct or unlawful detainment
Dismissal for failure to follow policy or negligence
Retail client terminating the security contract
Loss of public trust in your professionalism and brand
Tips for Officers
