Revolutionary changes to consumer price measurement have been announced by the Office for National Statistics of the UK, where the grocery scanner data will be introduced and the decades-old mechanisms will be updated by March 2026. The proposed changes are the adoption of the COICOP 2018 classification standards and the promotion of the use of administrative data in various sectors.
Revolutionary grocery scanner data transforms inflation measurement
According to the Consumer Prices Development Plan, the ONS plans to put grocery scanner data in its consumer price inflation bulletin in February 2026, which would cover 50% of the market share. Introducing the remaining 50 percent of the grocery market will involve utilizing manual price collection in-store; this process will involve online stores and physical collections. This forms a paradigm shift in the conventional approach to data collection, which has prevailed in the inflation measurement over the decades.
The change also involves the application of new multilateral pricing practices that were developed in cooperation with the international partners and the Economic Statistics Centre of Excellence, the GEKS-Tornqvist one. ONS has cooperated with its panel of experts and met the United Nations task forces, breaking associations that have never been witnessed before in terms of statistical methodology development. Vital to the statement of quality assurance is the fact that the scanner information has been running in parallel for a 1-year duration before incorporation.
Elimination of legacies can boost the process of modernization
In 2026, central data collection will start moving away from legacy technology, switching to a cloud-based strategic platform, and the feasibility of the remaining legacy enhancements will commence. This is a high-priority activity that will overcome infrastructural constraints that have restricted the versatility of ONS changing systems and adaptability to arising data demands.
The standard framework is an international standard used in classification
COICOP 2018 implementation is a high priority and complexity that requires analysis over a number of years. The ONS is in a discovery phase where it is striving to learn the key requirements as it may move closer to the Living Costs and Food Survey and Household Final Consumption Expenditure survey to put the implementation in place.
This underlying reorganization is impacting the Consumer Prices Index as well as the CPIH, which necessitates harmonization in various areas of statistics in the first place. COICOP 2018 revisions were completed by the United Nations, which led to the restructuring of UK consumer price statistics and reorganized them thoroughly. The work requires similar efforts to both develop methodologies and update systems on interlocking statistical systems.
The first half of 2026 is the date of the seasonally adjusted indices
A feasibility study on seasonally adjusted consumer price inflation methodology was done at the National Institute of Economic and Social Research, and development is currently underway at ONS. The first half will issue monthly seasonally adjusted indices, which will be published as supplementary tables, to give users the ability to improve their analytical capabilities.
The growth of administrative data promotes measurement accuracy
The ONS is strengthening the use of administrative data through consumer prices based on successes in grasping the use of administrative data in rail fares, second-hand cars, and in the statistics of private rentals. Further developments will involve the application of the existing data in the retailer scanners to other types, such as household products, and increased data from the retailer in the calculation of grocery indices.
The transformation of consumer price statistics in the UK will be the most important methodological development in decades, making the country one of the pioneers in terms of innovation in the field of the measurement of inflation on the planet. These wholesome changes will come with a high level of accuracy and international comparability without compromising the high standard of quality that is needed when making policies in the economy.
