We consider this to be down to a general economic improvement, better mortgage availability and the direct impact of the Government schemes.""We are confident of delivering our full year expectations, and demonstrating further steps in our goal of margin improvement, which remains our primary focus. In this improved market, our strong order book and outlet position is likely to lead to continued volume growth in the second half," it added.Net debt at June 30th 2013 is around £70m down from £135.2m for the same period in 2012.CJ
