A customer complaint isn’t just a sign of dissatisfaction – it’s a legal and reputational checkpoint for your business. In the fast-paced world of e-commerce, where thousands of orders are processed daily, product or service complaints are inevitable. What matters most is how they’re handled: efficiently, fairly, and within the legal timeframe. So, how long do you have to respond to a complaint? What are your responsibilities as a seller? And what happens if you miss the deadline? This article breaks it all down according to UK law and best practice in digital commerce.
What is a customer complaint – and when can one be made?
A complaint, in the legal sense, is a formal expression of dissatisfaction with a product or service, typically on grounds that it’s faulty, misdescribed, or unfit for purpose. In the UK, complaints are governed primarily by:
- the Consumer Rights Act 2015,
- the Consumer Contracts Regulations 2013,
- and where relevant, the Consumer Protection from Unfair Trading Regulations 2008.

Customers can make a complaint if the goods or services:
- do not match their description,
- are not of satisfactory quality,
- do not last a reasonable amount of time,
- or are not fit for the stated purpose.
For digital products and services, the same rules apply, with additional protection regarding download functionality and digital rights.
What is the legal timeframe to respond to a complaint in the UK?
While UK law does not specify an exact number of days to respond to a complaint, the Financial Conduct Authority (FCA) – which regulates financial and payment services – and the UK government’s consumer protection standards recommend the following:
- A clear, substantive response within 14 days of receiving the complaint.
- For complex issues, businesses should acknowledge receipt within 3 working days and provide an estimated timeframe for resolution.
For consumer goods, if a refund, repair, or replacement is due, the trader must act without undue delay and no later than 14 days after agreement to provide a refund. Failure to do so may breach consumer law and lead to legal or regulatory consequences.
Additionally, if no response is given, a customer may assume the trader is at fault – and pursue the matter with Trading Standards, the Financial Ombudsman Service, or through chargeback claims with their payment provider.
Why response time matters in the e-commerce sector
Online shoppers are particularly sensitive to post-purchase service. A slow or unresponsive complaint process can lead to:
- immediate loss of trust,
- negative reviews and social media backlash,
- reduced customer retention,
- and higher dispute costs through chargebacks or court action.
Chargeback – what is a chargeback?
Conversely, a quick and professional response can turn an unhappy customer into a loyal one. In competitive markets like fashion, electronics, and digital subscriptions, how you handle complaints is just as important as what you sell.
Handling refunds and returns – why seamless payment integration matters
In many cases, upholding a complaint means issuing a refund or exchange. According to UK law, once the return is agreed upon or the seller confirms the complaint, the refund must be processed within 14 calendar days.
To meet this requirement efficiently, retailers should:
- integrate with a modern payment platform that allows quick refunds,
- ensure their systems track transactions by order ID or product SKU,
- automate reconciliation and reduce manual handling.
Payment providers like Fenige offer tools for instant refunds, card-to-card transfers, and secure payment tracking, making it easier for sellers to comply with refund policies while maintaining customer satisfaction.
Can complaint response times be extended? Only with communication
Sometimes, resolving a complaint requires more time – e.g. involving a manufacturer, assessing damage, or conducting internal audits. In such cases, UK consumer guidelines recommend that traders:
- acknowledge the complaint within 3 business days,
- explain why more time is needed,
- and provide a realistic date for a full response.
Clear communication is critical. Failing to keep the customer informed may lead to secondary complaints, escalation to ombudsman services, or legal intervention.
Modern CRM and helpdesk systems can help businesses meet these standards by tracking complaints, sending updates, and managing deadlines automatically.
What are the risks of missing the deadline or not responding at all?
Ignoring a complaint, or responding too late, can expose a business to:
- formal action from Trading Standards or Ombudsman Services,
- chargeback claims via the customer’s card issuer,
- legal claims under Section 75 of the Consumer Credit Act,
- or damage to reputation and online ratings.

For financial services or payment-related complaints, firms regulated by the FCA must also comply with specific complaints-handling protocols – and failure to do so can result in fines or licence suspension.
Conclusion: complaints are a test of responsibility
In an era where customer experience is king, complaint handling is not just about meeting a deadline – it’s about protecting brand equity and ensuring legal compliance.
Whether you’re a merchant, marketplace, or subscription platform, having a transparent, timely, and traceable complaint process is essential. And with secure payment infrastructure from providers like Fenige, businesses can streamline refund handling, respond faster, and ensure compliance – all while reinforcing trust.
Because in modern commerce, it’s not mistakes that drive customers away – it’s how (and how fast) you deal with them.
