Internal flooding emergency

An internal flooding emergency is a drainage failure resulting in water or sewage flooding inside a property, requiring rapid intervention to limit damage. Typical causes include burst pipes, blocked WCs overflowing, washing machine waste hose detachment, and surcharge of basement drainage from external storms. Across North London, basement flats in Camden, Islington and Westminster are particularly vulnerable. Before the engineer arrives, occupants should turn off the water supply at the stop tap, isolate affected electrical circuits, move valuables above flood level, and document the event with photographs and video. The service includes water extraction, fault identification, temporary control or full fix, and a written report. Buildings insurance typically covers internal flooding from drainage failure, with loss adjusters requiring detailed contractor reports identifying cause and works.
