Camelot has reported its second-highest ever year of National Lottery ticket sales.

It recorded £6.7bn sales for the 2013/14 financial year, the second-highest annual total since the National Lottery launched in 1994. The sales were driven by changes to the National Lottery game which resulted in a strong second six months in retail, turning around a long-term decline in sales for the flagship game.

Sales figures for this year were only bested by 2012/13 (£6.9bn) which were buoyed by a series of Euromillions rollovers and a special 100 UK Millionaires Raffle held on the night of the Opening Ceremony of the London Olympics.

Scratchcards also had a good year, with sales of instant play games reaching a record £2.1bn in 2013/14, an increase of 3.8% on the year before. This was driven by the launch of 35 new Scratchcards over the year. The National Lottery estate also grew by around 10,000, with retailers joining the estate last year through Camelot’s standalone Scratchcard offering.

Sales director Duncan Malyon thanked Camelot’s retail partners for their work. “We’re delighted to have achieved our second-highest ever sales thanks to the invaluable help of our retailers,” he said. “We always said that matching the one-off performance of 2012/13 would be tough but to have very nearly done so – and without the feel-good factor of London 2012 and with far fewer big Rollovers on EuroMillions – underlines what a really good set of results this is. In particular, it’s great to see our flagship Lotto game back in year-on-year growth after a long period of sales decline and delivering substantially more money for the Good Causes.”

According to Camelot, its retail partners earned over £300m in sales commission in 2013/14, taking the total earned to date to over £5bn.

Malyon added that “sales have already got off to a very positive start in 2014/15”.
