British bakery chain Greggs has reported a 6.9% increase in total sales for the first half (H1) of 2025, achieving £1.027bn ($1.4bn), with like-for-like sales up 2.6%.

H1 2025 saw a continuation of positive sales trends from the initial 11 weeks, extending through May.

However, the heatwave in June led to a shift in consumer purchases, with cold drinks favoured over Greggs' traditional offerings and overall footfall reduced.

In the 26 weeks leading up to 28 June 2025, Greggs opened 87 new shops, resulting in a net increase of 31 outlets and bringing the total to 2,649 shops.

This expansion is in line with the company's target to open between 140 to 150 new shops by the end of the fiscal year.

Greggs has also been active in refurbishing its shops, completing 108 refits in the first half of 2025 and planning around 50 more for the second half.

The 2025 interim results, set to be released on 29 July, are expected to show a lower H1 operating profit compared to the same period in 2024, taking into account the stronger performance of the previous year and the timing of refurbishments and cost recovery efforts.

Looking ahead, Greggs maintains its cost inflation outlook and cost mitigation strategies, which are projected to improve performance in the second half of the year.

Given the current trading environment, the board is preparing for a modest decrease in full-year operating profit compared to 2024.

In June 2025, Greggs inaugurated its inaugural Eco Drive-Thru at Easton Lane, Winchester, marking a step in its sustainability efforts.

The new shop will serve as a testing ground for innovative in-store practices designed to diminish the ecological footprint of the chain's operations.
