How to reduce flooding damage to our homes

The problem

Climate change is set to increase the frequency and magnitude of severe flooding events in the UK. A new study ‘Projections of future flood risk in the UK’ finds that by the 2050s an additional half a million homes are projected to flood[1]. Over £200 billion worth of assets are at risk in Britain[2].

Properties do not need be near rivers, lakes or the coast to be at risk. The majority of flooding events are due to heavy rainfall and surface water not draining fast enough. We are now seeing this more frequently as rain is becoming more intense and urbanisation is increasing impervious surfaces. Urban environments where drainage has not been upgraded are particularly vulnerable.

Effects

Flooding damages properties, displaces people and leads to increased insurance premiums for residents and repair bills for landlords or owners. For example, the floods in 2007 led to 65,000 claims and are estimated to have cost £3 billion. Insurers’ claims for damage caused by floods so far this winter will reach £1.3bn.

The cost of damage to property as a result of a flood can be great. According to a report prepared for the Department for Environment, Food & Rural Affairs (Defra) repairing a house after a flood can cost between £10,000 and £50,000 depending on the flood depth[3].

There are also social related impacts such as emotional and psychological damage, physical health impacts, sentimental loss of irreplaceable items, and many others.

Things to consider

It is impossible to reduce all flood risk, or to defend against all possible floods in all places. However, it is possible to reduce the impact of a flood at the individual property level through flood resistance and resilience measures.

Defra found the costs of applying resistance measures, such as waterproof doors, windows and airbricks, can range between £3,000 and £10,000 for a whole house. While the cost of such measures can appear expensive, some may not cost more than the standard repairs and are likely to pay for themselves after a single flood event.

The UK has experienced heavy floods over the past decade, it is predicted that the risk of severe and more frequent floods will increase in the near future. Hence it is vital to understand what can be done to prepare and reduce impacts. 

Join us at the free event on 10th March to discuss future proofing properties and communities including the:

  • steps to take to plan for possible flood events
  • role sustainable urban drainage can play in reducing flooding
  • measures to take to make our homes resilient or resistant to flooding

NOTE: This event will feature a live flood of a home. This will demonstrate how water attempts to penetrate homes, the weaknesses in current construction and practical tips on what can be done to keep the water out, reduce damage and the practical steps that can be taken.
