A number of UK football clubs use both natural and artificial grass pitches for training. There are clubs that play outside of the premier league which do use synthetic turf pitches.
Do to the massive cost saving benefits of artificial grass, the costs to maintain the pitch can be much lower, and being artificial the grass allows clubs to use their pitches all year round. However artificial pitches have been banned in professional English football since 1995.
The ban is unusual as top professional leagues in many countries European including France, Holland, Scotland and Spain use of artificial grass to improve the usage and versatility of their stadiums. It’s also used in The Champions League and The World Cup.
