All 92 Premier League and Football League clubs - plus Wembley and the Principality Stadium - are being told to ensure their stadiums are free of potentially dangerous cladding.
The move follows the Grenfell Tower tragedy in which more than 80 people are thought to have died.
The Sports Grounds Safety Authority say they will write to every club and every local authority, and that cricket, rugby union and rugby league stadiums will also be checked.
Ken Scott, chief inspector from the Sports Grounds Safety Authority, said: "We are aware of what happened at Grenfell Tower and we are following developments. Lots of football grounds have used cladding.
"We will be writing to each and every local authority to make them aware of the situation. Venues attract a high level of supervision. They feature significant active and passive fire prevention systems including smoke alarms and fire extinguishers - but there cannot be complacency."
And he added: "The difficulty will be striking the balance. It is important to note that there is no sleeping risk here, these are not residential dwellings."
