Running an online shop gives you flexibility, but it also exposes your business to fraud. UK Finance’s Annual Fraud Report 2025 found that fraud losses across the UK reached £2.3 billion in 2024, with 2.9 million cases reported. For women-led e-commerce businesses, understanding eCommerce fraud prevention UK trends is not optional; it is part of protecting revenue, reputation, and customer trust.
According to Prowess data on women in business, women-led firms are a growing force in UK online retail, which makes targeted fraud guidance essential. Whether you sell handmade goods on your own website or run a multi-channel retail business, the same fraud techniques target small traders and larger brands alike. The good news is that a few practical changes to your checkout process, policies, and staff training can sharply reduce your risk.
Emerging eCommerce fraud trends in the UK
Fraudsters adapt quickly. The methods that dominated 2022 and 2023 have been joined by new tactics that exploit faster payments, AI tools, and busy customer service teams. Here are the trends every UK online seller should recognise.
Authorised push payment scams and the reimbursement shift
Authorised push payment (APP) scams happen when a customer is tricked into sending money to a criminal. UK Finance reported that APP fraud losses reached £459.7 million in 2024. For e-commerce sellers, the risk is twofold: a customer may blame your business after being scammed by a fake seller impersonating your brand, and you may face pressure to refund money that was never in your account.
From 7 October 2024, the Payment Systems Regulator’s mandatory reimbursement rules require the UK’s largest banks and payment service providers to refund victims of APP fraud up to £85,000, split between the sending and receiving providers. This changes the fraud landscape because receiving accounts used by criminals are now more closely monitored. As a seller, you should keep records of every transaction and use a business account with clear sender details so your legitimate payments are not flagged.
Chargeback and refund abuse
Chargeback fraud, sometimes called friendly fraud, happens when a customer receives an item but claims it never arrived or was not as described. The chargeback process is designed to protect cardholders, but it is increasingly used to obtain free goods. Small businesses bear the cost through lost stock, chargeback fees, and damaged payment processor ratings.
Card-not-present transactions carry the highest risk because the buyer and card are not physically present. UK Finance data shows that remote purchase fraud remains the largest category of card fraud affecting online retailers.
How account takeover attacks target sellers
Criminals buy stolen login details from data breaches and test them across thousands of websites. If a customer reuses a password on your store, the attacker can place orders, change delivery addresses, and redeem loyalty points. Account takeover is particularly damaging because the transaction may look legitimate until the real customer complains.
The National Cyber Security Centre warns that small businesses are a common target because they often lack dedicated security teams. The UK government’s Cyber Security Breaches Survey 2025 found that 36% of micro and small businesses identified a cyber security breach or attack in the last 12 months. A single compromised account can lead to chargebacks, negative reviews, and regulatory questions about how you protect customer data.
AI-assisted phishing and fake customer service
Generative AI has made it cheaper to produce convincing fake emails, websites, and customer service chats. Criminals now create lookalike domains and social media profiles that mimic trusted brands, then direct victims to fraudulent checkout pages. Some scams even use AI voices in phone calls pretending to be delivery companies or bank fraud teams.
Action Fraud, the UK’s national reporting centre for fraud and cyber crime, continues to receive thousands of reports of phishing campaigns targeting online shoppers each month. Sellers who communicate proactively with customers about how they will and will not contact them can reduce the chance that a scammer impersonates their brand.
eCommerce fraud prevention UK: practical strategies
Prevention does not require enterprise-level budgets. Most protections are built into your payment gateway or e-commerce platform and simply need to be switched on and monitored.
Enable Strong Customer Authentication and 3D Secure
Strong Customer Authentication (SCA) is a legal requirement under the UK’s implementation of the Payment Services Regulations 2017. It means customers must provide two of three verification factors: something they know, something they have, or something they are. Most UK card payments now use 3D Secure 2, which prompts the customer to verify a purchase through their banking app.
Make sure your payment gateway has SCA fully enabled for all online transactions. This shifts some liability for fraud away from your business and reduces unauthorised card use.
Verify addresses and require CVV
Address Verification Service (AVS) and Card Verification Value (CVV) checks add low-friction protection. AVS compares the billing address provided by the customer with the address held by the card issuer. CVV confirms the customer has the physical card in their hand. Together, they block many card-not-present fraud attempts.
You should also flag orders where the billing and delivery addresses differ significantly, especially for high-value items. A quick manual review of these orders can catch fraud before you ship.
Use fraud detection software
Modern fraud detection tools analyse transaction velocity, device fingerprints, IP locations, and behavioural signals in real time. They can spot patterns that humans miss, such as multiple orders from different cards using the same email address or sudden spikes in international traffic.
If you are unsure where to start, many e-commerce platforms, including Shopify, WooCommerce, and BigCommerce, offer integrated fraud filters or partner apps that use machine learning to score risk.
Write clear returns and chargeback policies
Clear policies protect you from refund abuse. Your terms should state your returns window, condition requirements, and refund method. Send order confirmations, tracking numbers, and delivery confirmations automatically so customers have a record of what they bought and when it arrived.
If a chargeback arrives, respond promptly with evidence. Banks and card schemes tend to side with merchants who provide clear documentation, including proof of delivery signed by the customer.
Train staff and talk to customers
Human error remains one of the biggest fraud risks. Train anyone with access to your admin panel or customer accounts to recognise phishing emails, suspicious orders, and social engineering calls. Set role-based permissions so no single person can change bank details, issue refunds, or access customer data without oversight.
Communicate with your customers about fraud. Tell them you will never ask for passwords or full card details by email, and publish your official social media handles and website URL. This makes it harder for scammers to impersonate you.
Protecting your business beyond the checkout
Fraud prevention sits alongside wider financial and operational protections. Keeping your accounts digital and up to date through Making Tax Digital helps you spot unusual transactions quickly. Cyber insurance for women-led SMEs can cover costs if a breach or fraud incident does occur.
The National Cyber Security Centre offers free guidance for small businesses, including checklists and training materials. For fraud incidents, report to Action Fraud and notify your payment processor and bank immediately.
Practical action steps to reduce fraud risk
- Review your payment gateway settings and confirm SCA and 3D Secure are active.
- Switch on AVS and CVV checks for every card transaction.
- Set order value and velocity limits that trigger manual review.
- Document your returns, refund, and chargeback process.
- Train your team to recognise phishing and social engineering.
- Report suspicious activity to Action Fraud and your bank.
eCommerce fraud prevention UK strategies are not about eliminating every risk. They are about making your business a harder target than the next one. With the right checkout controls, clear policies, and staff awareness, you can protect your revenue and keep your customers’ trust.
