Four fire engines and around 25 firefighters tackled a grass fire on Gordon Road in West Drayton.
Around half a hectare of grassland was alight. There were no reports of any injuries.
The Brigade’s 999 Control Officers took 21 calls to the blaze.
A London Fire Brigade spokesperson said: "The recent dry weather has made the ground extremely dry, which unfortunately means grassland and parks will burn quickly when exposed to even the smallest of sparks.
“Common causes of grass fires include carelessly discarded cigarettes or matches as well as rubbish left lying around such as glass bottles, which can start flames by magnifying the sun’s rays.
“Every one of us can help reduce the risk of fire and keep our communities clean, make sure rubbish is safely thrown away and cigarettes are always properly disposed of.
“If you see a grass fire, don't attempt to put it out yourself as grass fires can travel very quickly and change direction without warning. If you see signs of smouldering grass then call the Brigade and let us know where the fire is.”
The Brigade was called at 1737 and the fire was under control by 1838. Fire crews from Hillingdon, Heathrow, Southall and Feltham fire stations attended the scene.
