Irn-Bru manufacturer AG Barr has reported a 12.3% jump in half-year profit before tax to £16.6m.

Helped by good summer weather, AG Barr also posted a 5.8% increase in total turnover to £128.7m for the six months ending 28 July.

The company said its fizzy drink sales increased 7% during the period, while still-drink growth was 2%.

It said both Rubicon and Barr benefited from increased levels of distribution, while Irn-Bru’s sales were boosted by its ‘gets you through’ marketing campaign.

“We have made good progress across all fronts in the year to date.  We successfully navigated the challenging market conditions in the early part of 2013 and have accelerated our growth in the second quarter,” said AG Barr CEO Roger White.

AG Barr recently opened a new production and distribution site in Milton Keynes, which will help the company drive growth south of the border. 

The company’s proposed merger with Britvic fell through earlier in the year. It said total costs associated with the merger plans added up to £4.9m.
