Am I at risk from flooding?

How does water get into the house?




There are many ways for flood water to get into your house. Entrance points include walls, doors, windows, floors, services and drains.

Above ground
Floodwater can enter your house above ground in the following ways:

  • Through doorways and windows (even if they’re closed!)
  • Through airbricks or other ventilation openings
  • Through other gaps and around pipes and cables that pass through walls
  • Through party walls if the property next door is flooded
  • Through cracks in the brickwork
  • Through permeable, weathered or damaged brickwork, blocks, stone and mortar
  • At the damp proof course

Below ground
Floodwater can move underground before it becomes visible on the surface. Below ground floodwater can enter your house in the following ways:

  • Rising up through the floors (or through the walls of cellars or basements) in areas where the ground is made of permeable material, such as chalk, gravel or sand
  • Through drainage trenches in impermeable ground
  • Through drains and pipes leading into the house including:
    • Toilets
    • Sinks
    • Baths
    • Washing machines
    • Dishwashers
