SOFT drinks firm Britvic blamed wet summer weather for a slump in sales of its thirst-quenching products.

The company, which includes the Pennine Spring bottled water operation at Birkby, said revenues in its home market rose by just 0.7% between April and July.

But still drinks, which include bottled water brands Pennine Spring and Drench as well as Robinsons fruit drinks, fell by 13.3% in volume.

Britvic launched a double concentrate version of Robinsons over the period, but found that factors outside its control dented its trading performance.

The company said: “The weather in June had a negative impact on promotional activity around the Wimbledon tennis event, which is an important focus period for the Robinsons brand.”

The Essex-based group, which sells Pepsi products, said volumes of fizzy drinks fell by 1.6% as it faced heightened promotional activity by rivals.

However, higher average prices meant revenues were still 4.4% higher than a year ago.
