England's Voluntary Traffic Light Food Labelling System
Unlike many of its European counterparts, England has not adopted the Nutri-Score system. The UK government, through the Food Standards Agency (FSA), actively promotes its own voluntary front-of-pack (FOP) labelling system, often referred to as the 'traffic light' system. This label was designed to provide consumers with an easy-to-understand visual guide to the nutritional content of pre-packaged foods.
The traffic light system provides colour-coded information for four key nutrients:
- Fat: Shows the total fat content.
- Saturated Fat: Details the saturated fat component.
- Sugars: Covers the total sugar content.
- Salt: Displays the salt level.
Each nutrient is assigned a colour: red for high, amber for medium, and green for low. This visual cue helps busy shoppers quickly assess whether a product contains high levels of ingredients to be limited. Alongside the colours, the label also shows the energy content in kilojoules (kJ) and kilocalories (kcal) and often includes percentage reference intakes (% RIs).
While this system is widespread, its voluntary nature means not all manufacturers use it. Some companies have chosen not to participate, meaning the label is not universally present across all products on English shelves.
The Nutri-Score System Explained
The Nutri-Score system is a different approach to front-of-pack labelling, developed by independent scientists in France. It provides a single, summary evaluation of a product's nutritional quality using a five-colour scale with corresponding letters from A (dark green) to E (dark orange/red).
The score is calculated using an algorithm that balances 'beneficial' and 'unfavourable' nutrients per 100g or 100ml of a food product.
Favourable Nutrients (positive points):
- Protein
- Fibre
- Fruit, vegetables, nuts, and certain oils
Unfavourable Nutrients (negative points):
- Energy (calories)
- Saturated fatty acids
- Sugars
- Salt (sodium)
The final letter score (A-E) offers a quick, at-a-glance comparison of products within the same food category. Nutri-Score has been adopted voluntarily in several European countries, including France, Germany, Spain, Belgium, and Switzerland. The UK’s exit from the European Union has resulted in a divergence from potential EU-wide mandatory labelling, strengthening England’s reliance on its existing traffic light system.
Comparison of UK Traffic Light vs. Nutri-Score Labelling
| Feature | UK Traffic Light System | Nutri-Score System |
|---|---|---|
| Calculation Method | Grades four specific nutrients (fat, saturates, sugars, salt) individually. | Uses an algorithm to balance positive and negative nutrients into a single score. |
| Visual Representation | Uses red, amber, and green colour-coding for each nutrient. | Uses a five-colour scale with letters A to E. |
| Scope in England | Voluntary, but widely adopted by major retailers and manufacturers. | Not officially endorsed or mandated; sometimes seen on imported products. |
| Information Displayed | Nutrient-specific information for quick assessment. | Overall nutritional quality summary score for easy comparison within a category. |
| Focus | Highlighting specific nutrients to limit. | Providing an overall health rating to guide comparisons. |
The Nutri-Score Debate and its Relevance to England
The choice of food labelling systems is a topic of intense debate among public health experts, policymakers, and the food industry. While Nutri-Score is praised for its simplicity and potential to drive manufacturers towards reformulation, it faces criticism. Some arguments suggest it can penalise traditionally healthy products, such as certain cheeses and oils, due to their fat content, while potentially favouring ultra-processed foods that are artificially fortified. The UK traffic light system is also not without critics, with some arguing it can be difficult for consumers to interpret multiple colours when assessing a product.
The debate has a direct impact on England due to globalised trade and ongoing policy discussions. As some food companies and consumer groups advocate for an internationally recognised standard, the UK's position could be revisited. For example, some products manufactured in countries that use Nutri-Score might be imported into England carrying the label. Consumers need to understand what this means when making purchasing decisions.
Post-Brexit Food Labelling Landscape
Following its departure from the European Union, the UK gained the autonomy to set its own food labelling rules. This has resulted in a different regulatory path compared to the EU's ongoing discussions about a harmonised, mandatory FOP label. While the EU has considered Nutri-Score, the process has faced delays and political pressure, particularly from countries like Italy. England's continued reliance on its voluntary traffic light system, combined with mandatory nutritional information on the back of the pack, means the Nutri-Score is unlikely to become the official standard in the near future.
For consumers, this means familiarity with the UK traffic light system is key. However, remaining aware of alternative labelling methods like Nutri-Score can be helpful when encountering imported goods or products from multinational brands.

Conclusion: The Final Word on Nutri-Score in England
In summary, Nutri-Score is not the official food labelling system in England, which instead operates under a government-promoted, voluntary traffic light scheme. The traffic light system provides a snapshot of a product's fat, saturated fat, sugar, and salt content, using a simple colour code. In contrast, Nutri-Score offers a single, summary grade (A-E) based on a more complex algorithm balancing multiple nutrients. While the Nutri-Score is used in several European nations and is present on some imported products, it is not standard practice in England. Consumers should be familiar with the UK's traffic light system while understanding that other schemes exist, reflecting ongoing international debates on the best way to communicate nutritional information.
