Grocery Basket Inflation Tracker

Three ways. It is weekly rather than monthly, so it moves while a price change is still news. It is regional rather than national, which matters because the spread between regions is often wider than the headline figure itself. And it is adjusted for pack size, so a tin that shrinks from 900g to 800g at the same shelf price is recorded as a 12.5% price rise rather than as no change.

Online retailer listings in each region, collected weekly from a minimum of twelve retailers per region. Items are matched on brand, pack size and grade before comparison, and normalised to a standard unit. The full item list and weights are published with the index so anyone can check the calculation.

Yes, and most media-facing clients do. We build the index, run the collection and produce the monthly release; you publish it under your name with an Actowiz methodology note. The methodology stays fixed for the life of the index, which is what makes it credible to a reporter on a deadline.

No. Once a week's index is published it stands. If a collection error is found we publish a correction note alongside the original figure rather than silently restating history. That policy is the reason the series can be cited in coverage without a caveat.

Yes. Most clients start from one of the four standard baskets and then adjust the item list and weights to match their category or their customer. A dairy business might build a 40-item protein basket; a media outlet might build a "typical family shop" of 60 items. The weighting method stays the same either way.

A live dashboard, a REST API, weekly CSV or Parquet exports, and a formatted monthly release with charts ready for publication. Media clients usually take the release; pricing teams take the API. Both are included in the same licence.
