The company said it had adopted a "cautious stance" because secondary housing transactions and consumer confidence were "unlikely to be positive" in the coming months.
The group's consumer arm - most well-known for the DIY store Wickes - did particularly well, clocking up 6.5 per cent like-for-like sales growth in the first half.
Carter added: "In our view it is too early to precisely predict end market demand and we will continue to monitor the lead indicators we track and will react accordingly."

Laith Khalaf, senior analyst at Hargreaves Lansdown, said: "The company’s fortunes are closely attuned the housing market, as home purchases are often followed up by improvement works. Whilst there are doubts hovering over the UK economy, stocks like Travis Perkins could be in for a rough time.
"The company also sources products from over 50 countries, so the devaluation of Sterling after Brexit could squeeze margins, unless Travis can push the pain back onto suppliers."
