If Trading Standards has contacted you, visited your premises, or conducted a test purchase, this guide helps you understand what is happening, what your rights are, and how to respond. Most investigations can be resolved without prosecution if you cooperate and demonstrate good compliance practices.

  1. Understand what is happening

    Trading Standards officers have broad legal powers under the Consumer Rights Act 2015. They can enter your premises during trading hours without notice, inspect and seize goods, require you to produce documents, and conduct test purchases using young volunteers. Understanding the type of investigation helps you respond appropriately.

    Common investigation types

    • Routine inspection: A planned visit to check general compliance with trading standards law. Officers may inspect labelling, pricing, weights and measures, and product safety.
    • Complaint-driven investigation: A consumer or competitor has made a complaint about your business. The officer will focus on the specific allegation.
    • Test purchase failure: An underage volunteer attempted to buy age-restricted products and your staff completed the sale. This is a serious matter.
    • CMA referral: The Competition and Markets Authority has referred a concern about unfair trading practices, misleading pricing, or anti-competitive behaviour.

    Check any correspondence or paperwork carefully. It should state which authority is investigating, the legal basis, and what they are looking into.

  2. Review the area of concern

    Identify which compliance area is under investigation and review your current procedures against the relevant requirements. The guides below cover the most common areas of Trading Standards enforcement for retailers.

    Age-restricted products

    Requirements for selling age-restricted goods including alcohol, tobacco, knives, and fireworks. Covers Challenge 25, staff training, and refusal logs.

    Avoid unfair trading practices in retail

    How to ensure your pricing, advertising, and sales practices comply with consumer protection law. Covers misleading actions, misleading omissions, and aggressive practices.

    Product safety compliance for retailers

    Your obligations for ensuring products you sell are safe, including record keeping, product recalls, and traceability requirements.

  3. Gather your due diligence evidence

    The due diligence defence is your primary legal protection. Under the Digital Markets, Competition and Consumers Act 2024 and the Consumer Rights Act 2015, you can defend against charges by showing you took all reasonable precautions and exercised all due diligence to avoid committing the offence.

    Evidence to gather

    • Written policies: Your age verification policy, pricing policy, product safety procedures, and any standard operating procedures
    • Training records: Dated records showing staff training on relevant topics, refresher training, and competency assessments
    • Refusal logs: Records of age-restricted sale refusals, demonstrating your policy is actively followed
    • Supplier documentation: Invoices, certificates of conformity, safety data sheets, and product specifications from your suppliers
    • Complaint records: Your log of customer complaints and how they were resolved
    • CCTV footage: Preserve any relevant footage before it is overwritten by your system

    Handle customer complaints and disputes

    How to maintain complaint records, use alternative dispute resolution, and demonstrate a responsible approach to consumer issues.

  4. Respond appropriately

    Cooperate with investigators. Being obstructive or evasive will worsen your position. However, you also have rights that you should be aware of.

    Your rights during an investigation

    • Written notice: You are entitled to receive written notice of the allegations against you
    • Legal advice: You may seek legal advice before attending a formal interview
    • PACE interview: If you are interviewed under caution (PACE), you have the right to a solicitor and the right to remain silent
    • Written statement: You can provide a written statement rather than answer questions verbally
    • Appeal enforcement notices: You can appeal any formal enforcement notice through the courts

    Possible outcomes

    • No further action: The investigation finds no breach, or minor issues are resolved informally
    • Advice and guidance: The officer provides written advice on improvements needed
    • Formal caution: An admission of guilt recorded formally, but no prosecution
    • Improvement notice: A legal requirement to make specific changes by a deadline
    • Prosecution: Criminal proceedings for serious or repeated breaches, which can result in unlimited fines
  5. Prevent recurrence

    After the investigation is resolved, review and strengthen your compliance procedures. A second failure for the same issue will be treated far more seriously. Demonstrating you have learned from the experience and made improvements works strongly in your favour if any future issues arise.

    Key actions

    • Review and update policies: Revise any written procedures that the investigation exposed as inadequate
    • Retrain staff: Deliver refresher training focused on the specific compliance area, and document it
    • Strengthen record keeping: Implement or improve your refusal log, complaint register, and supplier checks
    • Schedule internal checks: Conduct regular self-audits of your compliance across all Trading Standards areas
    • Build a relationship with your local Trading Standards: Many offer free business advice services and Primary Authority partnerships
