The DIY and home improvement stores in Germany increased sales in like-for-like terms by more than three per cent in the first six months of 2011. The companies in Austria and Switzerland proved to be very satisfied in a survey of the members of the BHB trade association. Only June showed a fall in sales due to weather conditions and other factors. The association expects real sales growth of between 2.5 and 3.5 per cent for the rest of the year.
