Bellway has predicted a dip in volumes both for this year and next.
The housebuilder said the reservation rate for the four months to June 4 was down by 24.9% to 190 homes compared with the same period last year, while its forward order book had fallen from £2.4bn to £1.7bn.
Chief executive Jason Honeyman said: “While customer interest is currently healthy, the board remains mindful that cost-of-living pressures and the uncertain path of future interest rates could impact housing demand.”
