Whether you're reformulating to comply with the UK's upcoming HFSS advertising restrictions or to address low product ratings, the imperative is clear: act swiftly and strategically.

From 5 January 2026, the UK will enforce new advertising restrictions on products high in fat, salt, or sugar (HFSS). These regulations will prohibit paid-for online ads for identifiable HFSS products at any time and restrict TV ads for such products before 9pm. Businesses with 250 or more employees will be affected.

Simultaneously, our analysis reveals that the bottom 20% of products with at least 30 reviews in UK supermarkets since 2023 have an average rating of less than 4.0. This figure underscores a vital truth: these products don’t need more reviews—they need reformulating to succeed.

At CheckoutSmart, we view these challenges not as obstacles but as opportunities. Our SmartReformulation solution is designed to help brand managers update and relaunch poorly rated SKUs, ensuring products not only meet regulatory standards but also resonate with consumers.

The opportunity for improved taste with HFSS/LFH compliance

The upcoming HFSS/LHF legislation, effective from 5 January 2026, presents a strategic opportunity for brands to enhance both the nutritional profile and taste of their products. By reformulating to reduce levels of fat, sugar, and salt, and incorporating beneficial ingredients like fibre, protein, and fruits, companies can not only comply with regulatory requirements but also meet the growing consumer demand for healthier options.

Every Quarter, we analyse the Top 150 UK FMCG manufacturers and their online reputation in supermarkets. Our key reputation KPI is the percentage of SKUs that need new reviews. The fewer the number, the better the manufacturer is managing its reputation.

Based on our research and that of business school professors in the US, the three key measures that go into whether a SKU Needs new reviews are:

1. Minimum of 30 reviews: This involves checking if the SKU has at least 30 reviews in that retailer. If it does, we move on to section 2. If not, it requires new reviews.
   
   
2. Top 3 Fresh: Looking at the latest three reviews on the retailer's website, e.g., Tesco.com, which is displayed as the newest first, are any more than six months old? If yes, it needs new reviews; if not, go to 3.
   
   
3. Top 3 Fair: Look at the latest three reviews and their ratings out of 5. Are any of these more than 1.5 Stars different from (above or below) the average rating for the SKU in that retailer? If yes, then it needs new reviews. If "No," then this SKU in this retailer is optimised right now.

We check this data daily in every retailer and automatically get new reviews from 100% verified shoppers until they are no longer required. Working with our clients, we know that this kind of Always On program provides an exceptional ROI return of between 6 and 12 at a gross margin level.

That's £6 - £12 back for every £1 you spend on the program. Where else can you get that kind of return on your spending?

Product reviews are a hot topic in FMCG and eCommerce, but we regularly hear feedback from some that just don’t stack up against the data. Whether it’s scepticism about their impact on sales or outdated beliefs about how shoppers engage with reviews, these misconceptions can hold brands back. We will cover:

• The impact of product reviews on sales is minimal
  Based on case study data, we’ll show how reviews drive long-term sales growth.
• Reviews only matter to online shoppers
  In-store shoppers use reviews too—66% check them before purchasing.
• If my product is good, I can ignore negative reviews
  A product with an average rating below 4.0 is losing trust and sales—here’s why.
• Product reviews are just for retailer websites
  Smart brands use advertising, packaging, and in-store reviews to boost conversions.
• Reviews don’t matter for own-label products
  The gap between branded and own-label reviews is growing—own-label needs to catch up.

Now, let’s examine myth and reveal the truth about the power of product reviews.

Category management in Fast-Moving Consumer Goods (FMCG) is a delicate balance of art and science. While data-driven insights have always played a key role, product reviews have become a powerful tool for sharpening strategies and boosting category performance. These reviews offer a goldmine of consumer feedback and can guide decisions from product reformulation to marketing focus.

This post will explore how incorporating product reviews into your category management strategy can unlock new opportunities for brands and retailers. The five areas of opportunity are:

1. Understanding consumer preferences
2. Optimising product performance
3. Driving category growth
4. Supporting retailer listing decisions
5. Enhancing the impact of shopper marketing

At the request of one of our brand partners, we are stepping into the world of FMCG brand tracking. We are going to research some of the top brands in the UK and find out what shoppers think of them in terms of buyer recommendation, and the results may surprise you. 

These are the brands we included were:

NB All these brands are "Top" brands in the UK. They were chosen after shoppers selected ones they bought regularly from a long list of brands to ensure a significant number of responses for every brand. As a result, this list's "bottom" performers are still amongst the most frequently bought and top recommended brands in the UK.

The recent meteoric rise of artificial intelligence (AI) models is revolutionising how we interact with computers and access information online. But has AI made a significant difference in ratings and reviews, and is it what shoppers want?

Amazon has rolled out generative AI to create succinct product-level summaries of reviews for many of its products to support shoppers' decision-making process. Several clients have asked us to explore how this has impacted a shopper’s experience when using Amazon and understand how these features are perceived compared to ‘traditional’ ratings and reviews.

To do this, we created a study to research how regular Amazon shoppers use the site. The study simulates the shopping process for a selection of grocery category products. 

We received over 2500 responses, and our key findings challenge the notion that AI automatically benefits users.

The 4 key takeaways are:

1. Individual Ratings and reviews are as important as ever
2. Shoppers don't hang around when shopping for groceries on Amazon
3. Amazon's AI features are hardly used or even noticed
4. There is little evidence of AI improving the shopping experience, but the generations split opinion

Consumer-facing brands should leverage bespoke consumer feedback data to train or fine-tune AI / ML models to get ahead. These expert models can help them gain valuable insights into consumer preferences, behaviours, and sentiments, enabling them to optimise product descriptions, packaging design and advertising copy.

One application we have developed for such AI models is to assess and classify product reviews with helpful tags. Using consumer feedback as the basis, we have created proprietary measures of product reviews, such as how influential an individual review is and how strongly it reviews the product's taste or effectiveness.

By analysing these new measures, brand owners can identify their performance and patterns in consumer reviews, generate new insights, compare themselves to competition and even highlight individual reviews for a specific purpose, such as "suitable for advertising". 

Using bespoke shopper data to train AI models represents a significant opportunity for consumer-facing brands to enhance their understanding of consumers and markets.
