The BTHA's Make Time 2 Play campaign has won the Trade Association Forum's Best Corporate Social Responsibility Award.
The trade body was recognised for promoting the benefits of play and giving practical advice and play ideas to parents through the campaign.
"We are delighted to have won the CSR award at the Trade Association Forum Awards, particularly as it has taken the support of members and media partners to build the campaign over the past few years," said Natasha Crookes, director of communications and public affairs at the BTHA.
"It would not have been possible to do that without the generous help and support of the media partners who give free airtime to run the adverts, so we owe a huge thank you to Five Milkshake, Sky Kids, ITVB, Turner and Disney.
"Jeff Taylor of Arena Azure has been instrumental in helping the campaign to secure this airtime and the BTHA greatly appreciates the support he has given to this campaign."
Make Time 2 Play highlights the benefits of play and toys in the healthy development of children as they grow up. It gives help and advice through a dedicated website, Facebook and Twitter feeds and a phone app which gives hundreds of free play ideas.
