UK E-Commerce Legal Requirements: Your 2025 Compliance Guide

Alert
Disclaimer: This is general information, not legal advice. I provide these resources to support responsible website building. You remain responsible for ensuring your business complies with all applicable laws. Consult a qualified legal professional for specific advice.

Foundation Requirements First

Before diving into e-commerce specific requirements, ensure you meet all general UK website legal requirements:

  • Business identity disclosure
  • Privacy policy and GDPR compliance
  • Website accessibility
  • Cookie consent (if applicable)
  • Basic terms and conditions

See my companion guide: UK Website Legal Requirements: Your 2025 Compliance Guide for complete details on these foundation requirements.

Enhanced Terms and Conditions for Sales

When selling online, your Terms and Conditions need additional protections and disclosures.

Essential additions for e-commerce:

  • Order acceptance process
  • Payment terms and methods
  • Delivery arrangements and timeframes
  • Returns and refunds policy (beyond statutory rights)
  • Product descriptions and availability
  • What happens with faulty or damaged goods
  • Cancellation procedures
  • International shipping terms (if applicable)

Consumer sales (B2C): You cannot override consumers' statutory rights, but you can clarify your processes and set reasonable additional terms.

Business sales (B2B): More flexibility in terms, but they must still be fair and clearly written.

Legal requirements: Enhanced T&Cs for e-commerce are governed by:

  • Consumer Rights Act 2015 - sets out consumer rights for goods, services and digital content; requires terms to be fair and transparent
  • Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 - requires specific information disclosure and 14-day cooling-off periods for distance sales
  • Unfair Contract Terms Act 1977 - prevents businesses from excluding liability unreasonably in B2B contracts
  • Consumer Protection from Unfair Trading Regulations 2008 - prohibits misleading information in consumer contracts

WarningPenalties: Unfair terms are not binding on consumers. Misleading practices can result in enforcement action and unlimited fines.

Idea
Clear sales terms reduce disputes, returns, and customer service load. Efficient processes mean fewer problems and more satisfied customers.

VAT Registration and Cross-Border Sales

UK VAT Registration: Required if your annual turnover exceeds £90,000. Optional below this threshold.

What VAT registration means:

  • Add VAT to your prices (usually 20%)
  • Submit quarterly VAT returns
  • Display VAT number on invoices and your website
  • Keep detailed VAT records

Selling to EU customers:

  • Use OSS (One-Stop Shop) to handle EU VAT
  • Customers pay VAT upfront, avoiding customs delays
  • Simplifies the process for cross-border sales

Northern Ireland: Special rules apply for EU sales due to the Northern Ireland Protocol. Check current requirements.

Legal framework: VAT requirements are set by:

  • Value Added Tax Act 1994 - the main UK VAT legislation
  • The VAT Regulations 1995 - detailed implementation rules
  • Various Finance Acts that update VAT rates and thresholds annually

Idea
Proper VAT setup from the start avoids costly retrofitting and compliance issues. Plan for growth mindfully.

Payment Security: Protecting Customer Data

PCI DSS Compliance: If you process, store, or transmit credit card data, you must comply with PCI DSS 4.0.1 standards.

Common Payment Processors and Shared Responsibility: Most e-commerce businesses use third-party payment processors like:

  • Stripe - handles PCI DSS compliance for card data processing
  • PayPal - manages security for transactions through their system
  • Square - provides secure payment processing and hardware
  • Apple Pay/Google Pay - tokenised payments with enhanced security
  • Worldpay, Adyen, SagePay - enterprise payment solutions

Your Responsibilities vs Payment Processor Responsibilities:

What your payment processor handles:

  • Secure storage of card details
  • PCI DSS Level 1 compliance for card processing
  • Fraud monitoring and detection
  • Secure transmission of payment data
  • Most technical security requirements

What you're still responsible for:

  • Ensuring your website connection to the payment processor is secure (HTTPS)
  • Implementing Strong Customer Authentication (SCA) correctly
  • Never storing card details on your systems
  • Keeping your e-commerce platform and plugins updated
  • Monitoring for unauthorized access to your website
  • Having proper access controls for your payment processor account
  • Meeting PCI DSS Self-Assessment Questionnaire requirements (usually SAQ-A for hosted solutions)

Integration Method Affects Your Responsibilities:

  • Hosted checkout (recommended): Customer enters card details directly on processor's secure page - minimal PCI responsibilities for you
  • Embedded forms: Card details entered on your site but sent directly to processor - moderate responsibilities
  • Direct API integration: You handle card data before sending to processor - highest responsibilities and compliance requirements

Requirements:

  • Annual PCI DSS self-assessment questionnaire
  • Secure payment forms (HTTPS encryption)
  • Monitor for tampering or breaches on your website
  • Maintain secure networks and systems
  • Regularly test and update your e-commerce platform

Strong Customer Authentication (SCA): Most online card payments need two-factor authentication under PSD2 rules. Your payment processor typically handles this, but you need to ensure your checkout process supports it.

Card surcharges: You cannot charge extra fees for customers paying by card.

Legal framework: Payment security is governed by:

  • Payment Services Regulations 2017 - implements PSD2 in the UK, including Strong Customer Authentication requirements (Regulation 100)
  • Consumer Rights (Payment Surcharges) Regulations 2012 - bans excessive payment surcharges
  • PCI DSS 4.0.1 - while not UK law, compliance is required by card schemes and often contractually mandated by payment processors

WarningPenalties: Under PSD2: unlimited fines for serious breaches. Card scheme penalties for PCI DSS non-compliance can include increased transaction fees and termination of processing rights. Payment processors may suspend your account for non-compliance.

Idea
Secure payment processing builds long-term trust and reduces fraud-related costs. Efficient security measures protect both business and customers. Using reputable payment processors reduces your compliance burden while maintaining security.

Digital Markets, Competition and Consumers Act 2024 (DMCCA): The New Rules

This legislation took effect in April 2025 and introduced the strictest e-commerce rules yet.

What's now banned:

  • Fake reviews or paying for positive reviews
  • Drip pricing (hiding fees until checkout)
  • Misleading urgency claims ("only 2 left" when that's false)
  • Making it hard to cancel subscriptions
  • Dark patterns designed to trick users
  • Misleading environmental claims ("greenwashing")

New requirements:

  • Upfront pricing: All fees visible before checkout
  • Purchase transparency: Before customers buy, clearly show: your business identity, product details, total price including delivery, returns rights, cancellation terms
  • Subscription clarity: Renewal dates, costs, and easy online cancellation
  • Review authenticity: Only genuine reviews allowed
  • Green claims compliance: Environmental claims must follow the CMA's Green Claims Code

Green Claims Code - Key Requirements: The CMA estimates that 40% of green claims made online could be misleading. All environmental claims must be:

  • Truthful and accurate - you must live up to claims about products, services, or business practices
  • Substantiated - backed by verifiable evidence, certifications, or third-party audits
  • Clear and specific - avoid vague terms like "eco-friendly" or "sustainable" without concrete details
  • Complete - consider the product's full lifecycle from manufacture to disposal
  • Fair comparisons - any comparisons with competitors must be meaningful and substantiated
  • Not omitting important information - don't hide relevant details that affect consumer choice

Common greenwashing violations to avoid:

  • Using terms like "100% recyclable" when only parts are recyclable
  • Claiming products are "carbon neutral" without offsetting evidence
  • Using green imagery or nature photos to suggest sustainability without basis
  • Filtering systems showing "recycled" products that aren't predominantly recycled materials
  • Making general claims about being "environmentally friendly" without specific evidence

Legal framework: The DMCCA 2024 amends existing consumer protection laws:

  • Consumer Protection from Unfair Trading Regulations 2008 - enhanced with new prohibitions on fake reviews and drip pricing
  • Competition Act 1998 - strengthened powers for the CMA
  • Enterprise Act 2002 - enhanced enforcement mechanisms

WarningThe penalties: Up to 10% of global annual turnover OR £300,000 (whichever is higher). The Competition and Markets Authority (CMA) can now impose fines directly.

IdeaHonest, transparent practices build lasting customer relationships. Clear information reduces support queries and returns. Authentic reviews create genuine value for future customers.

Product Regulation and Metrology Act 2025: Marketplace Responsibility

This new law affects how online marketplaces handle product safety.

If you sell via Amazon, Etsy, or other marketplaces:

  • Both you and the platform share responsibility for product safety
  • Enhanced monitoring and recall procedures
  • Authorities have stronger powers for inspections and forced recalls

What this means:

  • Keep detailed product safety records
  • Respond quickly to safety concerns
  • Update your supplier contracts to cover new responsibilities
  • Monitor products throughout their sale period

Direct selling: If you sell directly from your website, you remain fully responsible for product safety and compliance.

Legal framework:

  • Product Regulation and Metrology Act 2025 - new law creating shared liability between online marketplaces and sellers for product safety
  • Consumer Protection Act 1987 - existing product liability law that continues to apply
  • General Product Safety Regulations 2005 - ongoing safety requirements for all products

WarningPenalties: Enforcement orders, unlimited fines, and potential criminal prosecution for serious safety breaches. Enhanced powers allow authorities to force product recalls and marketplace suspensions.

Idea
Responsible product sourcing and safety practices create long-term business sustainability. Avoiding shortcuts prevents costly recalls and reputation damage.

Info
For anyone setting up or running an online business in the UK, having robust, up-to-date website policies isn’t just good practice. It’s a legal necessity. The regulations around privacy, cookies, and online contracts shift constantly, and mistakes can be costly. That’s why I strongly recommend Termageddon for generating terms and conditions, privacy policies, and cookie disclosures.  It’s the policy tool I use myself because it ensures I am meeting my legal responsibilities across all the world.
