Wilson Bowden says that uncertainty over the election has led to a fall in reservations on its housing developments.
Rservation rates on Wilson Bowden housing developments have fallen in recent weeks because of uncertainty caused by the General Election.
The housebuilder said that although the market had improved since March it had been knocked back by the election announcement.
Chairman David Wilson said that first half completions were expected to be below the level achieved in 2004, but he predicted that the results would improve in the second half if customer confidence returned.
Group Chairman David Wilson said: “The market remains fickle and purchaser chains are taking longer to come to fruition.”
Wilson also said that the company was still being affected by planning delays. He said: “We continue to suffer from planning delays and one cannot resist the comment that the planning system is slowing more than ever and shows no sign of responding to what the government appears to be telling us, namely that more housing is required.”
