🇬🇧 Front-of-Pack Nutrition Labeling in UK

Front-of-pack nutrition labeling provides at-a-glance nutrition information and is guided by the FSA Reference Intake and traffic light system in United Kingdom.

What the Rule Is

Front-of-pack nutrition labeling (FOPL) appears on the front or main display panel of food packaging, offering a quick visual summary of nutritional content. Unlike the mandatory back-of-pack nutrition table, FOPL requirements vary between markets and are evolving significantly.

What You Must Include

Energy value per serving or per 100g on front of pack (EU/UK)
Key nutrients presented in the FOPL must match the back-of-pack Nutrition Facts
Reference intake (RI) percentages where required
Color coding or rating system aligned with local guidance
No claims that contradict the FOPL nutritional profile

Common Violations

FOPL data that contradicts the nutrition facts panel values
Using a voluntary FOPL scheme (e.g., Nutri-Score) incorrectly
Claim combinations that create a misleading overall impression (e.g., "high protein" prominently displayed while FOPL shows high saturates)
Not updating FOPL after recipe changes
FOPL values based on uncooked vs. cooked product confusion

Examples: Compliant vs Non-Compliant

Compliant Examples

UK traffic light labels showing red/amber/green for fat, saturates, sugars, salt with RI% per portion

Nutri-Score A–E grade aligned with the product's nutritional profile

Front-of-pack energy per serving in kcal/kJ matching the nutrition table

Non-Compliant Examples

Energy value on front of pack that differs from the nutrition panel

Using Nutri-Score "A" on a product with high saturates

Missing reference intake percentage when using the UK traffic light system

Frequently Asked Questions

Is front-of-pack labeling mandatory in UK?

Not fully mandatory, but the UK Reference Intake traffic light system is strongly recommended by FSA and widely adopted by retailers.

What is Nutri-Score and should I use it?

Nutri-Score is a color-coded A–E grade used across France, Germany, Belgium, Spain, and other EU countries. It is voluntary but increasingly expected by retailers. The EU may mandate a harmonized FOPL system — Nutri-Score is the leading candidate.
