Why Electronic Shelf Labels are the key to protecting your supermarket’s margins

There’s always a number of tasks to undertake in a busy supermarket environment, and manual pricing updates today aren’t just a critical admin task, they’re a significant drain on your bottom line. 

Labour costs in the UK are rising sharply, with retail labour expenses increasing by more than £5 billion in the past year alone, and understandably businesses of all shapes and sizes are looking at ways in which they can offset some of that cost with automation. 

For independent supermarkets, Electronic Shelf Labels (ESLs) can help save time, improve your margins, move stock and ensure you’re able to respond quickly to change. 

Here’s what you need to know. 

What are Electronic Shelf Labels? 

Electronic Shelf Labels are digital displays that are connected to your centralised system, and enable you to update pricing and other information instantly. From a practical perspective, this enables you to save time manually printing and updating labels, while ensuring information is accurate and timely, reducing error and maximising margins. 

How do Electronic Shelf Labels help protect margin? 

ESLs help protect your margins in a number of ways. Firstly, there’s instant synchronisation, meaning you can update pricing and promotions across your store – and across all sites – in an instant from your back office. 

For stock that’s approaching its sell-by date, you can mark down and promote quickly across multiple sites to increase the opportunity to sell, reducing food waste in the process. 

And, as food price inflation continues to rise – we ended 2025 with an annual 4.5% increase – you can adjust price points instantly to protect volume and margins. 

How do Electronic Shelf Labels help customers? 

As well as helping independent supermarkets protect margins and save time, ESLs enhance the customer experience and increase trust levels, too. 

From a customer perspective, accurate information is key, and ESLs ensure 100% accuracy between the price that’s displayed and the price that appears at the checkout, eliminating that friction that comes when manual error means prices don’t match. 

In addition, using custom fields, ESLs can display up-to-the-minute information about allergen data, ensuring you meet Natasha’s Law obligations, and can also support dual language displays, helping you cater to diverse communities.  

Focusing on your customers 

The  value proposition of an independent supermarket is top quality produce combined with exceptional customer service, and ESLs help you compete like a chain, while freeing up time to connect like a local. 

Various studies have shown that ESLs can reduce the time spent on manual price changes by up to 60%, winning back valuable time to focus on community spirit and personal service.  

Why now is the time to invest in ESLs 

Across Europe, the value of the ESL market is projected to reach USD1,005.74m (£756m) by 2033, expanding at a CAGR of almost 20% from 2025 to 2033, while this year Morrisons are rolling out ESLs into all of its stores.  

By implementing ESLs into your store now, you can create a point of difference today and help streamline and improve the back-office side of your business, too – setting your independent supermarket up for success over the coming years – while ensuring you still have the time to connect with customers, and deliver that true local service that will keep customers coming back.
