Topps Tiles’ share price has slipped after the retailer admitted it miscalculated sales for the first eight weeks of its financial year. 

Shares in the flooring specialist are down 3.7% today after it revealed the error in a filing. 

Last week the retailer reported that like-for-likes in the eight weeks since October 1 were up 0.8%.

However, today it said it had “discovered an error in the calculation” and like-for-likes in fact slid 0.3% in the period. 

Topps Tiles, which reported rising sales and profits for the year to October 1, said that the remainder of reported figures in its financial results remained unchanged.

The retailer’s share price has almost halved in the past year as the impact of Brexit and weaker consumer confidence has taken its toll.

Last week, chief executive Matt Williams said: “While consumer confidence has improved from its immediate post-referendum low, the measure remains in a slightly negative position.

“The further implications for consumer confidence and the subsequent impact on our business remain unclear and we will continue to monitor the economic data available closely.”
