Luminar, the embattled nightclub group, has this morning revealed like-for-like sales in the 12 weeks to 6 January down 19.4%, with December’s bout of snow badly impacting its business. In a trading statement the group said that excluding weather-affected weeks, the decline in like-for-like sales had reduced to 13.6%, compared to a decline of 16.9% for the seven weeks to 14 October and a decline of 20.2% at the half year. The 12-week decline of 19.4% comes on top of like-for-like sales declines of 13.8% for the Christmas period in 2010. Britain’s biggest nightclub group, which operates just under 80 large-scale late-night venues, said that year-to-date like-for-like sales for the 45 weeks to 6 January 2011 fell 19.6%. The declines come on top of falls in 2010 for the same period of 8.1%. Luminar, which is led by Simon Douglas, said that as expected margins were slightly lower in the period due to the introduction of premium drinks brands, to which customers had responded positively. It said that other initiatives, such as cocktails and live entertainment, had also been well received. As previously announced the group successfully refinanced its debt in December, agreeing a new three-year facility. Luminar said it was managing cash closely and was investing selectively.
