It was discussed on the BBC, Good Morning Britain, Channel 4, Sky News, ITV and TalkRadio, made front page news of The Times and appeared in 90 other national news publications. Zoopla have made the Air Quality rating system available as a tool on their website. Other property portals are using our API to produce Air Quality Ratings for every listing.
