Firefighters have issued a reminder of their cooking safety advice following a fire at an end of terrace block of flats on Strode Road in Willesden.
Part of a three roomed split level flat on the first and second floor was damaged by the fire. There were no reports of any injuries.
The fire is believed to have been accidental and was caused by a toaster left on and unattended.
A London Fire Brigade spokesperson said: "Avoid keeping items such as toasters under cupboards or in contact with combustible items such as tea towels or kitchen roll to prevent heat build-up.
"It's also important to make sure you keep toasters clean to help prevent fires.
“Firefighters also recommend that you have a look at our online Home Fire Safety Checker to make sure there are no hidden hazards in your home.
“The online tool will ask you a series of questions that will help us work out the level of risk in your home, or the home of someone you care for. It only takes a few minutes to get tailored advice to keep yourself and loved ones safe from fire.”
Control Officers took the call at 1458 and mobilised four fire engines and around 25 firefighters from Willesden, West Hampstead and North Kensington fire stations to the scene. The incident was over for firefighters at 1559.
