UK: Narrowing price gap between beef and lamb drives shopper switching
According to the Office for National Statistics (ONS), retail lamb inflation reached 8.0% in December 2025. This is 1% lower than the three-year average.
Lamb products saw a 3.8% increase in volumes purchased, accompanied by a 5.4% increase in spend year-on-year. Average prices paid increased by 1.6%.
This is a weighted average, which shows that shoppers are moving towards cheaper lamb products to counteract price rises.
For the total lamb category, consumers have been turning away from discount stores and heading to major supermarkets instead.
A rise in promotions at supermarkets has led to a decrease in average prices, attracting cost-conscious shoppers.
Discounters, who are less reliant on promotions, have, therefore, seen a decrease in volumes purchased.
The price gap between beef and lamb has been narrowing as beef has suffered from average price increases and consumers have switched to cheaper protein options.
The gap has gone from £2.13/kg at the start of 2023 to £0.59/kg at the end of 2025.
Beef has lost volumes to consumers switching to cheaper proteins, lamb has gained 346 t from this.
The biggest winners were pig meat pig meat and chicken as they are the cheapest protein options.
The lamb roasting joint category has seen a 12.2% increase in volume, followed by a 6.4% increase in spend and a 5.2% increase in average prices.
Lamb sales soared during the Christmas period, with roasting joints performing particularly well.
There were more promotions during the Christmas period, and the average price per volume decreased by 7.8%. This resulted in an 18.3% increase in volumes sold.
Premium tier roasting sales decreased, whereas standard tier roasting sales increased.
This suggests consumers are looking for better value for money, as lamb remains one of the more expensive roasting options.
The average price of a lamb roasting joint was £10.95, whereas the average price of a beef roasting joint was £12.40, making lamb a desirable and more affordable Sunday roast treat.
Leg roasting joints
Leg roasting joints make up the largest proportion of the lamb roasting category.
In the 12 w/e 28 December 2025, sales of leg roasting joints increased by 15.3% while spend increased by 7.8%.
Consumers were attracted by the 6.5% decrease in average prices due to a large increase in promotions.
Shoulder roasting joints
In the 12 w/e 28 December 2025, there were fewer promotions for shoulder roasting joints than for leg joints.
This could explain the 8.4% decrease in volume, 4.0% increase in spend and 13.5% increase in average prices.
The volume declines were not enough to counteract the large volume increases seen by leg roasting joints.
Lamb mince
Lamb mince has seen a 12.2% increase in spend, a 6.7% increase in volume and a 5.1% increase in average price.
Lamb mince has benefited from the rising price of beef mince and diced beef, and despite lamb being the most expensive mince, volumes are increasing.
For the 12 weeks ending 28 December 2025, the price differential between lamb and beef mince was £1.91/kg, the lowest it has been over the last two years.
Lamb sous vide
In the 12 w/e 28 December 2025, there was an 11.8% increase in spend on sous vide lamb, a 3.8% increase in volume and a 7.6% increase in average prices.
The price differential between lamb and beef sous vide has narrowed to just £0.26/kg for the 12 weeks ending 28 December 2025.
Despite rising prices in both supermarkets and discounters, supermarkets saw volume increases of 4.6%.
Promotional activity increased slightly, but not to the same extent as seen in other categories.
Lamb sous vide has benefited marginally from consumers switching away from beef sous vide.
With consumers prioritising convenience for their meal choices, and the average meal preparation time decreasing, items such as sous vide are becoming more popular.
