Profit increased by 4.8% to £34.9mln in the six months ended 14 April, while revenue rose by a similar percentage to £769.2mln.
Growth came from charging higher prices rather than selling more of its range of drinks, which include Robinsons fruit squash, Fruit Shoot and J2O.
Britvic, which is the UK’s largest supplier of soft drinks, only sold 1.19bn litres of drinks in the six months, compared with 1.24bn litres in the same period of last year.
Bosses said that reflected stockpiling by customers ahead of the ‘sugar tax’, which came into force last April and served to hike the price of full-sugar beverages.
Still, the FTSE 250 group said it had been a net beneficiary of the levy, driving consumers towards sugar-free versions of its Tango and R Whites drinks. Sales of Pepsi Max, which Britvic has the licence to produce and sell in the UK, also rose in the period.

“I am pleased to report that we have delivered another strong performance in the first half of the year,” said chief executive
“We have grown organic brand contribution in all our markets and increased group revenue, organic margin and adjusted earnings per share.
“As we anticipated, the soft drinks levy has benefited our portfolio, accelerating the consumer trend towards our heartland of low and no sugar brands.”
Having opened lower, Britvic shares were broadly flat at 937p in early deals on Wednesday.
