Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what estimate he has made of the potential impact of the Soft Drinks Industry Levy on the level of sugar intake by children.

The Soft Drinks Industry Levy (SDIL) came into law on 5 April 2018, having been announced in 2016. Between 2015 and 2024 sugar levels in drinks in scope of the levy reduced by 47%, and while no formal assessment of the impact on children has been undertaken, the scale of reduction will have an impact on the sugar intake of children.

Data from the National Diet and Nutrition Survey (NDNS), an ongoing Government survey of food consumption, nutrient intake, and nutrient status in the United Kingdom, showed a fall in sugar intakes between 2014 to 2019, in older children and adolescents. This appears to be partly driven by soft drinks contributing less to sugar intakes, likely as a result of the changes made to drinks in scope of the SDIL.

The latest results for 2019 to 2023 show that sugar intakes in children remain approximately double the maximum recommendation and children aged 11 to 18 years old are the highest consumers of sugar sweetened soft drinks. Diets high in sugar increase the risk of dental caries as well as weight gain, which can ultimately result in living with overweight and obesity and related adverse health outcomes. The NDNS will continue to monitor sugar intakes following reformulation of drinks in scope of the SDIL.

Academic modelling indicates that reductions in sugar from drinks subject to the SDIL may have prevented 5,000 cases of obesity in girls aged ten to 11 years old, with greater impact on those attending schools in the most deprived areas. Modelling data also suggests that the changes resulting from the SDIL may have reduced hospital admissions for dental caries related tooth extractions in those aged zero to nine years old and for asthma related issues in those aged five to 18 years old.

Following formal consultation, two changes to the SDIL were announced in the 2025 Autumn Budget which will apply from 1 January 2028:

• reducing the lower sugar threshold at which the levy applies from 5 grams to 4.5 grams of sugar per 100 millilitres; and
• removing previous exemptions for pre-packed added sugar milk-based and milk substitute, for example oat, soya, and/or almond, drinks.

The Department carried out a health benefits assessment to estimate the sugar and calorie reduction from these changes through product reformulation and consumer substitution to alternative drinks.

This analysis estimates a sugar reduction equivalent to per person per day calorie reductions of 0.3 kcal in five- to ten-year-olds, 0.4 kcal in 11- to 18-year-olds, 0.3 kcal in 19- to 64-year-olds, and 0.2 kcal in those aged 65 years old and over. This is equivalent to approximately four million kcal per day in children and 13 million kcal per day in adults.
