Tesco has gained further market share but CEO Ken Murphy says they are “taking nothing for granted”.

The supermarket giant released its interim results trading statement for 2025/26 today (2 October) and Tesco has grown its UK grocery market share to 28.4%. Murphy said the gains were “broad-based” across its business.

Group sales for the period are up 5.1% from £33,051m to £31,463m.

Murphy said he was pleased with the first half performance, “which builds on already strong momentum”.

“Our market share gains in the UK are a particular highlight and reflect the decisive action we took at the start of the year to further invest in value, quality and service,” he said.

“The extension of our savings programme is helping offset new operating cost inflation, including increased National Insurance and other regulatory costs. Sales have grown across all our businesses, with customer satisfaction scores improving once again.”

Over a 12-week period to early September, Tesco’s sales rose by 7.7% year-on-year, the fastest growth in the UK grocery sector in that interval. It also increased its UK grocery market share to 28.4%.

The retailer continues to forecast a relatively wide range for adjusted operating profit, between £2.7bn and £3bn, reflecting management’s caution amid cost pressures and competitive risk.

Murphy added: “The steps we have taken to keep prices down for customers have improved our price position relative to the market. We have continued to enhance quality across all our ranges, including Finest, which is now in its third year of double-digit sales growth.

“Our summer ranges also benefited from over 470 new products and we continued to deliver market-leading availability. The opening of our new semi-automated distribution centre in Aylesford will further support our core fresh food offer.”
