What happened
A fire broke out at an electrical substation on Victoria Passage, Aberdeen Place in St John's Wood. The blaze involved an electrical transformer and spread to the roof of a neighbouring residential block. Around 100 firefighters attended with 15 fire engines, including a turntable ladder and bulk foam unit. Approximately 80 to 100 residents were evacuated from nearby flats, with a major incident declared and later stood down. Thick smoke affected the area, prompting advice to keep windows and doors closed. Power supplies were not interrupted. The cause is under investigation by London Fire Brigade, UK Power Networks and the Metropolitan Police. No injuries were reported.
Contributing factors
A fault on a piece of equipment was reported by the operator as the origin of the fire. The cause remains under investigation.
Lessons learned
- Transformer fires at urban substations can spread to adjacent buildings, so operators should check separation distances and fire walls.
- Bulk foam units and turntable ladders help contain substation fires near homes, so response plans should include these appliances.
