Construction workers have been banned from wolf whistling at women at their building sites.

George Wimpey South Wales is sending out instructions to all its building contractors this week, warning workers not to whistle at women.

The company's sales and marketing director Richard Goad, who wrote the memo, said he hoped the move would make women feel more comfortable when looking for a new home.

Mr Goad, based at the company's Cardiff headquarters, said: "There's no doubt that first impressions last. There's little point in having a super show home unless a woman can get out of her car and feel comfortable looking around.

"The builders I've spoken to on site are happy enough with the ban.

"As far as they are concerned, if it encourages more women to visit our developments, then they think it can only be a good thing."

He said women often looked around building sites on their own, and added: "It all points to the fact that we really do need to look after our female visitors."

The company is currently building houses at sites in Cardiff, Merthyr Tydfil, Chepstow, Aberbargoed, Cardiff Bay and Abertridwr.

A spokeswoman said: "This is something that has been initiated in south Wales, but there is nothing to stop other regions doing it too."
