Four fire engines and around 25 firefighters tackled a shed fire in a garden on Indus Road in Charlton.
A shed, pergola and garden fence panels were completely destroyed by the fire. Half of a garden office was also damaged in the blaze. Thankfully there were no injuries.
A 25-metre cordon was put in place and firefighters cooled four gas cylinders to an ambient temperature as a precaution, as some cylinders can explode when exposed to heat.
The fire is believed to have been accidental and caused by incense sticks placed too close to combustible materials.
A London Fire Brigade spokesperson said: "Incense sticks, candles and oil burners are one of the most common causes of fire within homes. It’s really important that you never leave these items unattended.
"Make sure you place incense sticks in a suitable, fire-resistant holder and keep them away from curtains and anything else that can easily catch fire. Remember to put them out entirely when you leave the room and especially before bed.
"We also recommend taking some time to carry out a few simple checks to keep yourself and your loved ones safe. The Brigade’s online Home Fire Safety Checker can guide you around your home and provide you with specific advice to reduce fire risks.”
Control Officers took the first of 49 calls at 1709 and mobilised four fire engines and around 25 firefighters from Greenwich, Lee Green, Eltham and Plumstead fire stations to the scene. The incident was over for firefighters at 1841.
