Question to the HM Treasury:

To ask the Chancellor of the Exchequer, whether the Office for Budget Responsibility provided estimates between March 2016 and April 2028 on the potential impact that the proposed Soft Drinks Industry Levy would have on the Consumer Price Index (CPI); and what estimate her Department has made of the potential impact of that policy on the CPI in the 2018-19 financial year.

Forecasting the economy, including the impact of Government policy decisions on inflation, is the responsibility of the independent Office for Budget Responsibility (OBR).

The OBR set out its latest assessment of policy measures in its Spring Forecast 2026, published on 3 March 2026. The OBR did not publish a specific estimate of the impact of the Soft Drinks Industry Levy on inflation in that forecast, or in previous Economic and Fiscal Outlook publications since the levy was announced in 2016, which would include the impact for the 2018-19 financial year.
