Bank of England projection
Four-quarter CPI inflation rate (ONS series D7BT), central projection. Projections are for the quarter shown, as the Bank publishes them, so they are not directly comparable with the OBR's calendar-year or financial-year figures.

What the OBR forecasts
The OBR's forecast here is the percentage change in the consumer prices index on a year earlier, as a calendar-year average. It is the official forecast that the Government's Budgets and Statements are judged against under the Charter for Budget Responsibility. 32 earlier OBR forecasts are listed above with the outturn now recorded.
Forecasts and outturns are set side by side as the publishers give them. Later revisions to the data, changes in definitions and policy decisions taken after a forecast all affect the comparison; this page does not judge any forecast.
