Morrisons has launched an "unbeatable prices" commitment, pledging not to be beaten on price by its five biggest supermarket rivals on hundreds of everyday products. The move signals another potential intensification in the UK's grocery price war.

The announcement came as the chain also cut the price of a 250g block of salted butter by 13p, from £1.98 to £1.85, matching Aldi's price. The reduction helped Morrisons climb two places to become the third-cheapest supermarket in a weekly price comparison of eight essential items, according to analysis by the Manchester Evening News, with a basket costing £13.19, behind Aldi (£12.99) and Lidl (£13.11).

A commitment to undercut the competition

Morrisons, which runs around 500 supermarkets and 1,700 convenience shops, said the commitment guarantees that its shoppers will pay the same or less for more than 500 weekly staples, including bananas, tomatoes, carrots, bread, butter and chicken fillets. The promise also extends to fresh lines across its Market Street counters, including its fishmongers and bakeries.

Alex Paver, customer and marketing director at Morrisons, said: "Customers shouldn't have to choose between great prices and great quality – and at Morrisons, they don't have to. Our unbeatable price commitment means customers can trust that the prices on these products simply won't be beaten by Asda, Tesco, Sainsbury's, Aldi or Lidl."

A response to a changing market

The move comes as the retailer attempts to reverse a slide in its share of the UK grocery market. Figures from Worldpanel for the 12 weeks to August show Morrisons held an 8.5% share, making it the sixth-largest supermarket group. It was recently overtaken by Lidl and trails behind Aldi, Asda, Sainsbury's and Tesco.

The new commitment comes two years after Morrisons first launched a price match against hundreds of Aldi and Lidl products, and follows a difficult period for the chain. Company accounts showed Morrisons cut almost 5,000 jobs last year. Data from Companies House showed average monthly workforce fell from 101,144 to 96,232 for the year to October.

Wider implications and availability

The commitment is being marked with in-store and online signage and is available to shop by Click & Collect. It does not apply at Morrisons Daily stores or through third-party services such as Deliveroo, Amazon and Just Eat.

The scheme comes as a separate analysis, run by the Manchester Evening News, tracked the price of a basket of eight items—bread, milk, butter, coffee, tea bags, beans, chicken and beef mince—at six major supermarkets. Across the basket, only Asda's butter price changed, rising 1p to £1.99, leaving the rankings as Aldi £12.99, Lidl £13.11, Morrisons £13.19, Sainsbury's £13.23, Asda £13.33 and Tesco £13.50.
