Twelve fire engines and around eighty firefighters tackled a fire at Barwell Business Park on Leatherhead Road in Chessington.
A warehouse unit was destroyed by the blaze. Fire crews deployed a drone to provide an aerial view of the blaze and used aerial ladder appliances as they worked to bring the blaze under control. There were no reports of any injuries.
Station Commander Neil Guyett, who attended the scene, said: “Fire crews arrived to find a well-developed fire and worked hard to bring it under control in what was a protracted incident. There was thick smoke issuing across the business park."
The Brigade was called at 1836 and the fire was under control by 2225. Fire crews from Surbiton, Kingston, Sutton, Twickenham, Croydon and Norbury fire stations attended the scene.
The fire is believed to be accidental but the cause has been recorded as undetermined.
