1. Main points
As alcohol, tobacco or road fuel duty were unchanged in the Budget, only changes to Vehicle Excise Duty (VED) will have a direct impact on the Consumer Prices Index including owner occupiers' housing costs (CPIH) and Consumer Prices Index (CPI) 1-month inflation rates in financial year ending (FYE) 2022.
Over FYE 2022, it is estimated that the Budget changes will have a cumulative downward effect of 0.03 percentage points on both CPIH and CPI 12-month inflation rates, because the 12-month inflation rates are affected by base effects from changes announced in previous Budgets.
It is estimated the changes to VED introduced in April 2021 will have an upward contribution to the CPIH and CPI 1-month inflation rates of 0.02 and 0.03 percentage points, respectively.
2. Overview of the estimated effect of the Budget
This article explains the estimated effect of implementing measures announced in the March 2021 Budget, previous Budgets, and pre-Budget reports on the Consumer Prices Index including owner occupiers' housing costs (CPIH) and the Consumer Price Index (CPI). The estimated impact on the Retail Prices Index (RPI), a legacy measure that is currently required under legislation, is presented in Section 6.
The estimated effect of the March 2021 Budget on consumer price inflation is based on applying the proposed duty rates to the CPIH and CPI. By measuring the effect on the item and aggregated indices, it is possible to estimate how the 2021 Budget may affect consumer price inflation.
It should be noted that our approach is unable to measure the effects of all the proposed changes in the 2021 Budget and does not take into consideration the indirect effects of policy changes within the 2021 Budget. The Office for Budget Responsibility (OBR) outlines the inflationary impacts of the policies announced in the 2021 Budget in the Economic and Fiscal Outlook – March 2021.
The effects of Spending Review 2020 on tobacco duty are reflected in this article. However, we have not reflected the impact of the temporary reduction in VAT, announced on 8 July 2020. The effect of this change on measures of consumer price inflation was explored in Impacts of Eat Out to Help Out on consumer prices: August 2020.
This article does not attempt to quantify the impact of changing consumer or producer behaviour, nor any other secondary impact following the Budget policy announcements. The estimated contributions assume all announced changes are passed on immediately and in full to consumers as soon as they come into effect. In practice, this is unlikely as changes to duties may affect the index over a period of months as stocks deplete.
Back to table of contents3. Budget measures that will affect the CPIH and CPI
Table 1 details the measures announced in the 2021 Budget that will affect the Consumer Prices Index including owner occupiers' housing costs (CPIH) and the Consumer Price Index (CPI) 1-month inflation rates in the financial years ending (FYE) 2021 and 2022, along with the estimated magnitude of the effect.
We have not included an estimate of the impact of the Minimum Excise Tax for cigarettes because the effect on the headline inflation figures is likely to be negligible.
Aside from including owner occupiers' housing costs (OOH) and Council Tax, CPIH is otherwise identical to CPI. The size of the contributions for components other than OOH and Council Tax are exaggerated in the CPI compared with the CPIH because they account for a larger proportion of the overall index.

Table 2 presents a comparison of the effect on the Consumer Prices Index including owner occupiers’ housing costs (CPIH) and the Consumer Price Index (CPI) 1-month inflation rates of the Budget measures that were implemented in the financial year ending (FYE) 2021, and those known measures that will be implemented in FYE 2022. There is also the possibility of further changes being announced in the next Spending Review (confirmed in Budget 2021) and subsequent Budgets.
The known measures that will be implemented in FYE 2022 are estimated to increase the CPIH 1-month inflation rate by approximately 0.02 percentage points and the CPI 1-month inflation rate by approximately 0.03 percentage points.

The following tables show the cumulative effects on the all items Consumer Prices Index including owner occupiers' housing costs (CPIH), and the Consumer Price Index (CPI) 12-month inflation rates of the 2021 Budget measures implemented in the financial year ending (FYE) 2021 and known measures that will be implemented in FYE 2022. They also show the likely timing of effects on the CPIH and CPI 12-month inflation rates, assuming all announced changes are passed on immediately and in full to consumers as soon as they come into effect.
There is also the possibility of further changes being announced in the next Spending Review (confirmed in Budget 2021) and subsequent Budgets.
Effects on the CPIH 12-month inflation rate
It is estimated the known Budget measures implemented in FYE 2022 will decrease the CPIH 12-month rate by 0.03 percentage points. This is because the 1-month rate inflation changes of 0.02, implemented in FYE 2022, will be offset by 1-month rate changes of 0.05 in FYE 2021.
| CPIH date | Budget measures impacting in the financial year ending 2022 (Percentage Point Change) | Effect¹ | Cumulative effect² |
|---|---|---|---|
| Apr 2021 | Increases in vehicle excise duties. | 0.02 | |
| Previous year's increases in vehicle excise duties drop out of the 12 month comparison. | -0.02 | 0.00 | |

Back to table of contents6. Effects on other measures of consumer price inflation
In accordance with the Statistics and Registration Service Act 2007, the Retail Prices Index (RPI) and its derivatives have been assessed against the Code of Practice for Statistics and found not to meet the required standard for designation as National Statistics. The RPI continues to be used for purposes such as the indexation of pensions, rents and index-linked gilts. For further information, please see Users and uses of consumer price inflation statistics.
It is estimated the known Budget measures implemented in the financial year ending (FYE) 2022 will decrease the RPI 12-month rate by 0.04 percentage points. This is because the 1-month rate inflation changes of 0.02, implemented in FYE 2022, will be offset by 1-month rate changes of 0.06 in FYE 2021.
| RPI date¹ | Budget measures impacting in the financial year ending 2022 (Percentage Point Change) | Effect² | Cumulative effect³ |
|---|---|---|---|
| Apr 2021 | Increases in vehicle excise duties. | 0.02 | |
| Previous year's increases in vehicle excise duties drop out of the 12 month comparison. | -0.01 | 0.01 | |
