However, he added demand was healthy and the market was growing “steadily and sustainably”.
Sales for the year to date rose to 0.66 per outlet per week, slightly up on the same time last year.
As a result, the UK’s second biggest housebuilder said its operating profit margin would rise around four percentage points from last year’s 13.6 per cent, up from its forecast for a three percentage point rise.
The news sent shares up four per cent to 122.2p.
