Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate her Department has made of the increased cost to businesses as a result of the expansion of the Soft Drinks Industry Levy (SDIL), including directly through paying the increased SDIL and indirectly through the demand of product reformulation.

The changes to SDIL announced at Budget 2025 were confirmed following extensive industry engagement through the ‘Strengthening the Soft Drinks Industry Levy’ consultation, which was open from 28 April to 21 July 2025. Representations from businesses, and the trade bodies representing them, were received and considered as part of this process.

On 25 November 2025, the government published its summary of responses to the consultation. An assessment of impacts – including economic impacts for businesses – of the announced policy changes can be found within the Summary of Responses document here:
