Four fire engines and around 25 firefighters responded to a fire at a restaurant with offices above on Old Jewry in City of London.
A small fire in the restaurant's ducting was extinguished before the arrival of the Brigade. One of the Brigade’s 32-metre turntable ladders was used as a water tower at the scene.
The fire is believed to be accidental and a result of cooking processes.
A London Fire Brigade spokesperson said: "We'd like to remind restaurant and takeaway owners to ensure they don't have dirty ducting. If you don't clean the ducting in your extraction system regularly, you're at a greater risk of ducting fires.
"You should also make sure you keep the hob, cooker hood and extractor fan clean too – built up fat and grease can ignite and cause a fire."
The Brigade's 999 Control Officers took over 10 calls to the fire. The Brigade was first called at 1547 and the fire was under control by 1733. Crews from Shoreditch, Dockhead, Shadwell and surrounding fire stations attended the scene.
