UK Traffic Light Food Labels: How to Read Front-of-Pack Signals
Learn how UK traffic light food labels use colour coding and reference-intake cues, and how SafeChoice can help compare packaged foods.
Quick answer
UK front-of-pack traffic light labels use colour-coded cues for nutrients such as fat, saturates, sugars, and salt, plus energy information. Use them as a quick shelf signal, then check the full nutrition declaration, ingredient list, serving size, allergens, and product category.
Key takeaways
- Traffic light colours are quick comparison signals, not complete food verdicts.
- UK front-of-pack guidance focuses on nutrients such as fat, saturates, sugars, salt, and energy.
- A red label cue means inspect the reason and compare similar products.
- SafeChoice can connect front-pack signals with ingredients, additives, scores, and alternatives.
- For allergies, pregnancy, or medical needs, use the package and qualified guidance.
What UK traffic light labels show
GOV.UK guidance describes a front-of-pack scheme combining colour coding and percentage reference intakes. Public guidance explains that traffic light labels tell shoppers whether a food has high, medium, or low amounts of fat, saturated fat, sugars, and salt, and also show energy.
This makes the front of the package useful at the shelf, but it should still lead to a full label check.
| Front cue | Typical meaning | What to verify next |
|---|---|---|
| Green | Lower level for that nutrient | Check serving and ingredients |
| Amber | Medium level | Compare similar products |
| Red | Higher level | Inspect the reason and frequency |
| Energy | Kilojoules and calories | Use with serving size and full nutrition declaration |
How shoppers should use the colours
Use colours for comparison within a category. A ready meal, sauce, cereal, and snack should not be judged as if they play the same role in the diet.
A product with one red cue may still be an occasional fit. A product with several red cues may deserve a closer comparison with alternatives.
How SafeChoice helps UK shoppers
SafeChoice can help shoppers connect front-of-pack colour signals with ingredient explanations, additive notes, score reasons, and healthier alternatives.
That is useful when a front label looks simple but the ingredient list is long or the serving size is hard to compare.
Limits to remember
Traffic light labels do not replace allergy checks, pregnancy guidance, product warnings, or medical advice. They are a quick nutrition summary, not a personal safety decision.
The full package label remains the source for ingredients, allergens, storage instructions, and warnings.
