UK Retail Labelling Laws and Regulations
Price Marking Order 2004
The Price Marking Order 2004 (PMO) sets out clear requirements for how retailers in the UK must display prices. Originally coming into force on 22 July 2004, the PMO implemented the EU Directive 98/6/EC into UK law, creating clear rules on price marking and unit pricing for many goods.
While the law has remained, the order has evolved with amendments added in 2010, 2014 and 2015, to refine and clarify requirements. More recently, the Price Marking (Amendment) Order 2024 and Price Marking (Amendment) Order 2025 have been presented to parliament, with the latest guidance planned to take effect from 6 April 2026.
There are several changes within this legislation that retailers must meet. Further simplifying transparency, prices must be clearly displayed for both the selling price and the unit price across more product categories. This also applies to promotional offers, unless a specific exemption applies.
For large but short-term promotions, a general notice may be used to indicate the offer, provided it is reasonable and not a replacement for updating individual prices where required. For example, if a promotion applies only to a specific product or brand, the individual price for that product must be updated to reflect the promotion.
A key change under the new guidance affects products offered at multiple prices, such as through loyalty schemes. In these cases, all applicable prices, both loyalty and non-loyalty, must be clearly displayed along with unit pricing.
Retailers must also follow enhanced price display rules, including the consistent use of metric units and clear, accessible pricing in line with the Equality Act 2010.
When selling goods to consumers, the PMO requires traders to follow clear pricing rules, including:
- Showing the selling price for all items
- Display the final selling price, including VAT and any other taxes
- Clearly showing price information in sterling (£)
- Pricing information positioned close to the goods
Unit Pricing
Unit pricing is a main requirement under UK retail pricing law and plays a role in helping consumers compare value. Alongside the selling price, retailers must also display a unit price, which shows the cost per standard unit of measurement, such as per kilogram, litre, metre, or item.
This requirement already applies to loose goods, such as:
- Fruit
- Vegetables
- Meat
- Certain multipack products
But from April 2026, it will extend to many more categories, including:
- Cereals
- Detergents
- Cosmetics
- Other goods sold in varying sizes or weights
The aim is to provide consumers with a consistent base for comparison, regardless of packaging or quantity. The upcoming amendment to the PMO further strengthens this rule. Where products are offered at more than one price, such as a standard price and loyalty scheme price, each selling price must be clearly displayed along with its unit price and any conditions that apply.
Reduced or sale prices must show both the new selling price and unit price, unless a limited general notice exception applies. Certain deposits, such as those under deposit return schemes, must be shown separately and excluded from the selling and unit prices.
By clearly presenting prices per standard metric unit, shoppers no longer need to calculate the value themselves. This prevents misleading pricing practices and enables quick, informed decisions, even during promotional activity, to create a fairer and more transparent shopping experience.
Consumer Protection Act 1987 (CPA 1987)
The Consumer Protection Act 1987 (CPA 1987) prevents unfair pricing tactics, protecting consumers from paying more than expected or purchasing under false assumptions. It supports the principles of fair trading, transparency and trust, ensuring consumers can make informed purchasing decisions and are not subject to unclear or dishonest pricing.
Under Section 20, it is an offence for businesses to provide incorrect price indications for goods or services, whether through price tags, shelf labels, advertisements, catalogues or even verbal statements. A price is considered invalid if the original price was less than stated or if it didn’t clearly explain any conditions attached to it. This includes hidden fees, false ‘sale’ or discount claims, and price comparisons, for example, advertising “Was £50, Now £20” when the product had never been sold at the higher price.
The risk of not complying with labelling laws
Failing to comply with UK price labelling laws carries legal, financial and reputational risks. Enforcement is primarily carried out by Trading Standards at a local level and the Competition and Markets Authority (CMA) using a combination of routine inspections, consumer complaint investigations and test purchasing to find non-compliance.
Trading Standards officers regularly visit physical stores and review online businesses to ensure prices are clear, accurate and not misleading; this includes checking shelf-edge prices match those charged at the till. Consumer complaints submitted through the Citizens Advice Consumer Service often bring investigations, while test purchases are commonly used to confirm that displayed prices, promotions and sale claims are genuine. They also actively track websites, online marketplaces and social media advertising for hidden charges or fake discount comparisons.
Enforcement Action
Enforcement ranges from informal advice and good-practice letters for small issues, through to fixed-penalty notices, civil court cases, and fines of up to £300,000 or 10% of global turnover (whichever is higher) under the DMCCA. In serious cases, criminal prosecution may occur.
Beyond fines, pricing labels need to be corrected immediately, and products may need to be removed from sale – all of which can be costly and disruptive. Perhaps most damaging is the impact on consumer trust. Unclear or incorrect pricing frustrates customers, leading to complaints, reduced purchases, and negative reviews. Over time, this can damage brand reputation in ways that are difficult and costly to rebuild.
Why retailers find compliance challenging
Retailers can find price labelling compliance challenging due to the fast movement and complexity of modern retail operations. Promotions, discounts, and changing supplier costs result in frequent price changes, increasing the risk of inaccurate pricing, particularly when managing thousands of SKUs.
Relying on manual processes such as bulk back-office printing, posting replacement labels to stores, or even handwriting in-store is time-consuming and prone to mistakes. You quickly find inconsistencies between shelf prices and those charged at the till, and it’s not uncommon for labels to be misplaced or fall off, further impacting price accuracy.
Data management is also a challenge. Inconsistent data formats, poor integrations between inventory and POS systems, a lack of standardisation, and reliance on manual data entry all contribute to real-time pricing accuracy being difficult.
How to make price labelling compliance easier
Keeping up with the impact of changing price and labelling regulations while juggling day-to-day retail operations puts pressure on retailers, no matter their size. Making it a priority to stay up to date with regulatory standards and understanding what change is needed provides a strong foundation for compliance.
Technology plays a crucial role in reducing these risks by improving pricing accuracy and minimising human error. Pricing inaccuracies, illegible labels, and inconsistent information all increase the likelihood of errors that undermine customer trust and breach regulatory standards.
Invest in a flexible price labelling solution
Investing in a robust labelling solution offers many benefits for retailers, helping to maintain compliance, protect profits, and enhance operational efficiency. Without an effective system in place, retailers are exposed to compliance risks.
Label printing solutions, such as Label IQ, streamline pricing and labelling processes by removing handwritten labels and simplifying processes, reducing human error and protecting brand reputation. This enables retailers to launch promotions and sale pricing quickly, print clear and accurate shelf edge labels, and update or replace labels on the spot.
Batch printing functionality allows retailers to manage high-volume price changes, from promotions to product launches, across entire stores or sub-departments. Match online prices and ensure consistency across all channels by updating labels in-store or in the warehouse, all while keeping operations fast and efficient.
Investing in a modern labelling system minimises risk and maximises revenue, with retailers gaining speed, accuracy, and being able to ensure labelling compliance.
Conduct regular price checks
Without a process in place, conducting regular price checks is difficult to achieve. Unless your store team are equipped with the right technology, you’re left relying on time-consuming and error-prone pen and paper methods.
Tools, such as Price Verification, further support compliance, enabling instant confirmation that advertised shelf prices match your data file. With a simple scan of a QR code, store colleagues can quickly identify and immediately correct discrepancies on the spot.
Consider your label design
Taking a considered approach to your label design is also important, ensuring mandatory information is not only displayed but also easy to read. If your labels are poorly designed or difficult to read, then they may be illegible. Using standardised label templates with consistency for key information helps ensure clarity across all products, reducing the risk of inconsistencies.
With evolving legislative requirements, you may need to update your label designs to maintain compliance. Many systems are inflexible, making it impossible to change your label templates, but Label IQ removes that rigidity. With our support, label templates can be amended to suit your business needs, making it simpler to stay compliant.
Together, this approach helps retailers adopt a simpler, more reliable pricing labelling process, one that is easier to manage, supports ongoing compliance, and ultimately builds customer confidence and trust.
