What Is a Coupon Code? How to Use One in the UK
Have you ever found a discount code while shopping online but weren’t sure how to use it? A coupon code is a simple way to claim an eligible offer at checkout. Depending on the retailer, it could give you money off your order, free delivery or a discount on selected products.
In the UK, these codes are also commonly called voucher codes, promo codes or discount codes. Here’s how they work, where to find them and what to check before placing an order.
What Is a Coupon Code?
A coupon code is a combination of letters, numbers or both that you enter at checkout to claim a promotional offer. For example, a retailer might offer 10% off selected products or £5 off orders above a certain amount.
Some codes are available to everyone, while others are reserved for new customers, newsletter subscribers or shoppers buying specific products.
It’s worth checking the conditions before using a code. An offer might not apply to everything in your basket, so read the terms before placing your order.
How Does a Coupon Code Work?
Most online shops have a dedicated box on the basket or checkout page. Follow these steps to use a code:
- Find a coupon code for the retailer where you want to shop.
- Add your chosen products to your online basket.
- Go to checkout and look for a box labelled “Promo code”, “Discount code” or “Voucher code”.
- Enter the code and select the apply button.
- Check the updated order total before paying.
For example, if you have £50 worth of eligible products and a valid code gives you £5 off, your total would fall to £45 before delivery charges or other applicable costs.
If the price doesn’t change after entering the code, check the offer’s conditions. You may need to spend more, choose different products or meet another eligibility requirement.
What Are the Different Types of Coupon Codes?
Retailers use several types of promotional codes. Understanding the differences can help you decide which offer is worth using.
Percentage discount codes: These reduce the eligible price by a percentage. A hypothetical 10% discount on a £40 purchase would save £4.
Fixed amount discount codes: These take a set amount off an eligible order. A £5 code could reduce a qualifying £30 basket to £25.
Free delivery codes: Some retailers offer free standard delivery through a promotional code. Check whether the offer has a minimum spend or excludes certain delivery options.
Welcome codes: New customers may receive a discount when signing up for a newsletter or creating an account. These offers often have specific conditions.
Product-specific codes: Some discounts apply only to selected brands, products or categories. Fashion shoppers, for example, can check the Mars The Label discount codes page for available promotions.
Before choosing an offer, compare the final price rather than looking at the discount alone. A smaller saving may be more useful if it applies to the products you actually want.
What Is the Difference Between a Coupon Code and a Voucher Code?
The terms coupon code, voucher code, promo code and discount code are often used interchangeably when shopping online. They generally refer to a code used to claim a promotional offer.
In the UK, shoppers frequently use the terms “voucher code” and “discount code”. However, the wording can vary between retailers.
A gift voucher is slightly different. It usually represents a monetary value that can be redeemed towards a purchase, subject to its terms. A promotional code typically provides a discount or another benefit instead.
Always check what an offer includes before assuming it works like a gift voucher.
Why Is My Coupon Code Not Working?
A code that looks valid might not work with every purchase. Here are some common reasons:
- Expired offer: The promotion may have ended.
- Minimum spend: Your basket might not meet the required amount.
- Product exclusions: The code may exclude sale items, certain brands or specific categories.
- Customer restrictions: A welcome code may only be available to new customers.
- Typing mistakes: An extra space or incorrect character can prevent a code from working.
- Other promotions: The retailer may not allow the code to be combined with another discount.
If a code fails, read the terms and check that your products qualify. You can also look for another offer, but make sure the replacement is relevant to your order.
Where Can You Find Coupon Codes in the UK?
Before paying full price, it’s worth checking whether the retailer has an offer available.
Retailer websites: Check the retailer’s sale or promotions section for current discounts and special offers.
Email newsletters: Some shops send welcome offers and exclusive promotions to subscribers. Check the terms before signing up.
Seasonal sales: Black Friday, Boxing Day and other promotional periods can bring discounts on selected products. A separate code may not be necessary.
Daily Voucher UK: You can browse all stores on Daily Voucher UK to find retailer pages featuring voucher codes, discount offers and deals. You can also check the Alohi SA discount codes page for offers listed for that retailer.

When shopping with an unfamiliar retailer, it’s worth checking its reputation and the terms of sale. Citizens Advice provides consumer advice that may help if you encounter a problem with a purchase.
The best approach is to compare the available code with the retailer’s current price. If an item is already discounted, a promotional code may not provide any additional saving.
