Sector body British Summer Fruits reported a 40% increase in value sales at retail level to £28m on the back of a 36% rise in volume sales to 4,600 tonnes.
Growers in Herefordshire and Worcestershire in the KG Fruits co-operative reported raspberry volumes six times greater than in 2004.
Some 198 tonnes were produced from late September to mid-November, compared with 34 tonnes for the same period last year.
Warm weather in September and October, coupled with strategic planting of crops, including late-season Driscoll varieties, extended the season and helped boost sales, said growers.
Sales of British strawberries through UK supermarkets enjoyed their 11th successive year of growth, said British Summer Fruits.
Value sales rose 13% year-on-year to £129m at retail, with volume sales of almost 43,000 tonnes compared with 37,000 tonnes last year.
Cherries also enjoyed growth, up 71% to 560 tonnes, as did blackberries, which rose 49% to 406 tonnes.
