How to Claim a Refund for Faulty Online Purchases: The Complete 2027 UK Guide

Shopping online has never been more popular. UK consumers spent over £120 billion online in 2025, and that figure continues to grow year on year. But with that convenience comes a familiar frustration: the parcel that arrives damaged, the laptop that stops working after a fortnight, the dress that looks nothing like the photograph on the website. When things go wrong, many shoppers feel powerless, especially when a retailer responds with a wall of terms and conditions or a flat refusal to issue a refund.

Here is the truth: you are not powerless. Not even close.

The Consumer Rights Act 2015 and the Consumer Contracts Regulations give UK online shoppers some of the strongest consumer protections in the world. Whether you are dealing with a faulty product, a delivery that never arrived, or a retailer who refuses to honour your legal rights, the law is firmly on your side. The key is knowing exactly what those rights are and how to enforce them.

This complete 2027 guide covers everything you need to know about claiming refunds for faulty online purchases. We will walk through the critical 30-day rule, the legal test for faulty goods, your right to change your mind, warranties and guarantees, what to do when a retailer refuses to cooperate, and how to write a formal complaint letter that forces them to take you seriously.

The Legal Framework: What Protects You When Shopping Online?

Before diving into the specifics, it is worth understanding the legal landscape. Several pieces of legislation work together to protect UK online shoppers.

The Consumer Rights Act 2015 is the cornerstone of your protection. It applies to all goods bought from a UK trader, whether in a shop, online, over the phone, or by mail order. The Digital Markets, Competition and Consumers Act 2024, which came into force in phases throughout 2025 and 2026, has significantly strengthened enforcement, giving the Competition and Markets Authority (CMA) new powers to directly fine retailers who breach consumer law without needing to go through the courts.

The SAD FART Test: What Makes a Product Legally Faulty?

Under the Consumer Rights Act 2015, any goods you buy from a UK retailer must meet certain standards. A useful way to remember these standards is the acronym SAD FART, which stands for:

Satisfactory Quality. Goods must not be faulty or damaged when you receive them. They must be of a standard that a reasonable person would consider satisfactory, taking into account the price paid, the description given, and any other relevant circumstances. A £50 blender is not expected to last as long as a £300 one, but neither should fail within the first week.

As Described. The item must match the description provided by the retailer, whether in the product listing, the photographs, or any verbal description given before purchase. If you order a sofa described as "solid oak" and it arrives made of chipboard, it is not as described. If a laptop is listed as having a 512GB SSD but only has 256GB, it is not as described.

Fit for Purpose. Goods must be fit for the purpose they are ordinarily supplied for, as well as any specific purpose you made known to the retailer before buying. If you told the retailer you needed waterproof boots for hiking in the Scottish Highlands and they sold you a pair that leaked in light rain, they are not fit for purpose.

And last a Reasonable length of Time. Goods should last a reasonable amount of time given their nature and price. There is no fixed rule here — what is "reasonable" depends on the product. A cheap pair of earphones might reasonably be expected to last a year, while a high-end washing machine should last a decade or more.

If an item fails to meet any of these criteria, it is legally considered faulty, and you have the right to take action under the Consumer Rights Act 2015.

The 30-Day Short-Term Right to Reject

This is the most powerful right you have as an online shopper, and it is one that many retailers hope you do not know about.

Under Section 20 of the Consumer Rights Act 2015, if you buy goods that turn out to be faulty — meaning they fail the SAD FART test — you have a strict 30-day window from the date you take ownership of the goods (usually the date of delivery) to reject the item and demand a full refund.

During this 30-day period, the retailer cannot force you to accept a repair or a replacement instead of a refund. If you want your money back, they must provide it. The only exception is if the goods are perishable and the 30 days would not be a reasonable period for rejection — for example, fresh food.

Critically, because the item is faulty, the retailer is legally responsible for the cost of returning it. Do not let them tell you otherwise. You should not be a single penny out of pocket for returning a product that was faulty when it was delivered to you.

What Counts as "Taking Ownership"?

The 30-day clock starts from the date you receive the goods, not the date you ordered them. If a delivery is delayed, your 30-day window begins when the item actually arrives. If you ordered multiple items and they are delivered separately, the 30-day period runs from the date each item is delivered.

Your Rights Between 30 Days and Six Months

If you discover a fault after the initial 30-day window has closed but within the first six months of ownership, you still have strong legal protection, though the rules change slightly.

During this period, the law presumes that any fault was present at the time of purchase, unless the retailer can prove otherwise. This is a significant legal presumption in your favour. The retailer cannot simply claim the fault developed after you bought it — they must prove it.

In this situation, you must give the retailer one opportunity to repair or replace the faulty item. It is generally up to the retailer to choose which option is cheaper or more practical for them. However, if the repair or replacement is unsuccessful, takes an unreasonable amount of time, or causes you significant inconvenience, you are then entitled to a full refund or a price reduction if you choose to keep the item.

Your Rights After Six Months

After six months, the burden of proof shifts. You must now demonstrate that the fault was present at the time of purchase, rather than arising from normal wear and tear, accidental damage, or misuse.

This can be challenging, but it is not impossible. For high-value items such as appliances, electronics, or furniture, obtaining an independent expert report is often the most effective way to establish that a fault is inherent rather than caused by use. The cost of such a report can sometimes be recovered if your complaint is upheld.

It is worth noting that the Consumer Rights Act 2015 does not impose a maximum time limit on how long after purchase you can make a claim. The relevant limitation period under the Limitation Act 1980 is six years in England and Wales (five years in Scotland). However, the practical difficulty of proving a fault was present at purchase increases significantly over time.

The 14-Day Cooling-Off Period: Your Right to Change Your Mind

One of the most significant advantages of shopping online compared to buying in a physical shop is your legal right to change your mind, even if the item is not faulty.

Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, when you buy goods online, over the phone, or by mail order, you have a cooling-off period. This gives you the right to cancel your order for any reason at all — you do not have to give an explanation.

The rules work as follows. You have 14 days from the day you receive your goods to notify the retailer that you wish to cancel. Once you have given notice, you have a further 14 days to return the goods. The retailer must then refund you within 14 days of receiving the goods back, or within 14 days of you providing proof of postage, whichever is earlier.

The retailer must refund the basic delivery cost you paid when placing the order. However, unless the item is faulty, you are generally responsible for the cost of returning it, provided the retailer clearly stated this in their terms and conditions before you placed the order.

There are some important exceptions to the cooling-off right. It does not apply to personalised or custom-made items, perishable goods, sealed items that have been unsealed after delivery (such as CDs, DVDs, or software), or services that have already been fully performed with your consent.

Warranties and Guarantees: What They Mean for You

Many products come with a manufacturer's warranty or a retailer's guarantee. It is important to understand how these interact with your statutory rights under the Consumer Rights Act 2015.

Your statutory rights are separate from and in addition to any warranty or guarantee. A warranty or guarantee cannot take away or reduce your legal rights — it can only add to them. If a retailer tries to tell you that your warranty has expired and therefore you have no rights, they are wrong.

A manufacturer's warranty is a voluntary promise made by the manufacturer to repair or replace a product if it develops a fault within a specified period. Warranties typically last one to two years for most consumer electronics and appliances. If a product develops a fault within the warranty period, you can claim against the manufacturer directly, or you can still exercise your rights against the retailer under the Consumer Rights Act.

A retailer's guarantee is a similar promise made by the shop or website where you bought the product. Some retailers offer extended guarantees beyond the manufacturer's warranty period, sometimes for a fee.

The key point is this: your rights under the Consumer Rights Act 2015 exist independently of any warranty or guarantee. Even after a warranty expires, you may still have rights against the retailer if you can demonstrate that the fault was present at the time of purchase or that the goods did not last a reasonable length of time.

When a Delivery Does Not Arrive

A separate but equally important area of online shopping rights concerns deliveries that go missing or arrive late.

Under the Consumer Contracts Regulations 2013, if you place an order online and the retailer has agreed to deliver by a specific date, they are in breach of contract if they fail to do so. If no specific date was agreed, the retailer has a default period of 30 days to deliver your order.

Critically, the legal responsibility for ensuring your order is delivered lies with the retailer, not the delivery company. If a parcel goes missing, is stolen from your doorstep, or is delivered to the wrong address, your complaint is with the retailer, not with the courier. The retailer chose the delivery company and is responsible for their performance.

If a delivery fails, you are entitled to ask the retailer to re-send the item or provide a full refund, including any delivery charges you paid. If the retailer refuses, you have grounds for a formal complaint.

Step-by-Step: How to Claim Your Refund

If you have a faulty item, a missing delivery, or a product that is not as described, follow this methodical process to enforce your rights effectively.

Step 1: Act Quickly

The 30-day short-term right to reject is your most powerful tool, but it is time-limited. As soon as you discover a fault or a problem, take action. Do not wait to see if the issue resolves itself.

Step 2: Gather Your Evidence

Before contacting the retailer, collect all the evidence you can. Take clear photographs of any fault or damage. Keep all packaging, receipts, and order confirmation emails. Note the date of delivery and the date you first noticed the problem. If the item is not as described, take screenshots of the original product listing.

Step 3: Contact the Retailer in Writing

Always communicate with the retailer in writing — by email or letter — rather than by phone. A written record is invaluable if you need to escalate the matter later. Clearly state the nature of the fault, the date of purchase and delivery, the specific remedy you are seeking (refund, repair, or replacement), and the legal basis for your claim.

Step 4: Send a Formal Complaint Letter

If the retailer ignores your initial contact, offers an inadequate response, or refuses to comply with the law, escalate to a formal complaint letter. A well-drafted letter citing the specific provisions of the Consumer Rights Act 2015 demonstrates that you understand your rights and are prepared to take further action.

Step 5: Escalate if Necessary

If the retailer still refuses to cooperate, you have several escalation options available to you.

How to Write a Complaint Letter That Gets Results

A formal complaint letter is often the turning point in a dispute with a retailer. Companies have legal teams and compliance departments that recognise the language of consumer law. A letter that cites specific legislation, states a clear deadline, and outlines the consequences of non-compliance is far more likely to be escalated internally and resolved in your favour than an angry email.

Here is a template you can adapt for your own situation.

Template: Formal Complaint Regarding Faulty Goods Purchased Online

[Your Name] [Your Address] [Your Email Address]

[Retailer's Name] [Retailer's Customer Service / Complaints Department Address]

[Date]

Reference: Formal Complaint — Order Number: [Your Order Number]

Dear Sir/Madam,

I am writing to make a formal complaint regarding goods I purchased from your website on [Date of Purchase]. The item in question is [Description of Item], purchased at a price of [Purchase Price], under order reference [Order Number]. The item was delivered on [Date of Delivery].

Upon [inspection / use], I discovered that the item is faulty. Specifically, [describe the fault in clear, factual terms — e.g., "the screen developed a crack along the left-hand side within seven days of delivery, despite the item having been used with reasonable care and stored appropriately" / "the item does not match the description on your website, which stated [original description], whereas the item I received [describe the discrepancy]"].

Under the Consumer Rights Act 2015, goods supplied by a trader to a consumer must be of satisfactory quality, fit for purpose, and as described. The item I have received fails to meet [the satisfactory quality / fit for purpose / as described] requirement under the Act.

As I am notifying you of this fault within 30 days of taking delivery of the goods, I am exercising my short-term right to reject the goods under Section 20 of the Consumer Rights Act 2015. I therefore require a full refund of the purchase price of [£XX.XX], including the original delivery charge of [£XX.XX], totalling [£XX.XX].

As the goods are faulty, it is your legal responsibility to arrange and pay for the return of the item. Please provide a pre-paid returns label or arrange for the item to be collected at your expense within the next 14 days.

I expect a full written response to this complaint within 14 days of the date of this letter. If I do not receive a satisfactory response by [Date 14 days from now], I will escalate this matter without further notice, including initiating a chargeback through my bank, reporting the matter to Trading Standards, and, if necessary, pursuing a claim through the Small Claims Court.

I prefer all further communication regarding this matter to be in writing via email to [Your Email Address], to ensure a clear record of our correspondence.

Yours faithfully,

[Your Signature] [Your Printed Name] [Your Contact Telephone Number]

Escalating the Dispute: Your Options

If a formal complaint letter does not resolve the matter, you have several powerful escalation routes available to you.

Chargeback (Debit or Credit Card)

If you paid by debit card, you can ask your bank to reverse the transaction through the Chargeback scheme. This is a customer service process operated by the card networks (Visa, Mastercard, and American Express) and is not a legal right, but banks generally process legitimate chargebacks. You typically have 120 days from the date of the transaction to raise a chargeback claim.

Section 75 (Credit Card)

If you paid by credit card and the item cost between £100 and £30,000, you have a legal right to claim a refund from your credit card provider under Section 75 of the Consumer Credit Act 1974. Your credit card provider is jointly liable with the retailer for any breach of contract or misrepresentation. This is a statutory right, not a discretionary policy, and it applies even if you only paid a deposit by credit card.

Alternative Dispute Resolution (ADR)

Many retailers are members of an Alternative Dispute Resolution (ADR) scheme, which provides an independent third party to resolve disputes without going to court. The retailer is required to tell you about any ADR scheme they belong to in their final response to your complaint.

Trading Standards

If you believe a retailer is systematically breaching consumer law, you can report them to your local Trading Standards service via the Citizens Advice consumer helpline. Trading Standards can investigate and take enforcement action against businesses that repeatedly break the law.

Small Claims Court

As a last resort, you can take the retailer to the Small Claims Court (known as the Money Claims Online service in England and Wales). The process is designed to be accessible to ordinary consumers without legal representation. The small claims track handles disputes up to £10,000 in England and Wales. Court fees are modest and recoverable if you win.

Frequently Asked Questions

Can I return an online purchase if I simply change my mind?

Yes, for most online purchases. Under the Consumer Contracts Regulations 2013, you have 14 days from delivery to notify the retailer that you wish to return the item, and a further 14 days to send it back. You do not need to give a reason. However, you will generally be responsible for return postage costs unless the item is faulty.

What if the retailer has gone into administration?

If the retailer has gone into administration, your options depend on how you paid. If you paid by credit card, Section 75 of the Consumer Credit Act 1974 gives you a claim against your card provider. If you paid by debit card, try a chargeback claim. If you paid by PayPal, you may be able to raise a dispute through PayPal's buyer protection scheme.

Does my warranty cover everything?

No. Warranties typically cover manufacturing defects but often exclude damage caused by accidental damage, misuse, or normal wear and tear. However, your statutory rights under the Consumer Rights Act 2015 exist independently of any warranty and may provide broader protection in some circumstances.

What if the retailer is based overseas?

If you bought from a UK-based retailer, your rights under the Consumer Rights Act 2015 apply regardless of where the goods were manufactured. If you bought from an overseas retailer with no UK presence, your rights are more limited. Paying by credit card or using a payment service with buyer protection is particularly important when buying from international sellers.

Can I claim compensation for inconvenience or distress?

In some cases, yes. If a retailer's breach of contract has caused you quantifiable financial loss — for example, you had to hire a replacement item while waiting for a refund — you may be able to claim those additional costs. Compensation for pure distress is less common in consumer disputes but can be awarded in exceptional circumstances.

Stop Letting Retailers Ignore Your Rights

Every year, UK consumers lose millions of pounds because they do not know their rights, or because they give up when a retailer pushes back. A faulty product, a missing delivery, or a retailer who refuses to issue a refund is not just an inconvenience — it is a breach of your legal rights, and you are entitled to redress.

The most effective tool you have is a well-drafted, legally-referenced formal complaint letter. When a retailer receives a letter that cites the Consumer Rights Act 2015 by section number, states a clear deadline, and outlines the consequences of non-compliance, they know they are dealing with someone who understands the law and is prepared to use it.

LetterForce makes this easy. Our AI-powered service generates structured, legally-referenced complaint letters tailored to your specific situation in minutes.
