Question to the Department for Business, Innovation, Science and Trade:

To ask the Secretary of State for Business, Innovation, Science and Trade, what assessment his Department has made of the potential impact of unit pricing measures used by supermarkets, including pricing by item, weight and package size for equivalent products, on consumers' ability to compare prices and identify best value for money; and whether his Department has plans to review existing unit pricing regulations to require retailers display prices using a single consistent metric for items.

The Price Marking Order (PMO) requires traders to display the selling price and, where applicable, the unit price for goods, enabling consumers to compare similar products and assess value for money. The PMO was recently updated so products sold by weight or volume must show unit prices in kilograms or litres. The Digital Markets, Competition and Consumers Act 2024 confirmed that the price displayed on the shelf must be the price the consumer pays. The Government engaged extensively with industry on these proposals and keeps them under review to support consistent pricing information for consumers.
