Flood defences could reduce losses by an estimated 360% across river, surface water and coastal flooding - JBA
One in four UK properties are at risk of flood according to analysis from JBA Risk Management.
It also shows that flood defences could reduce losses by an estimated 360% across river, surface water and coastal flooding, with coastal flooding up to 1300% higher without coastal flood defences. Losses from river flood are reduced by an estimated 295% from river flood defences.
Nikki Pilgrim, technical director, JBA Risk Management commented: “The data, and recent flood events around the world, are a clear warning that flood remains a pervasive risk that must be taken seriously.
”Our new UK Flood Model’s enhanced functionality enables the insurance market to fully understand their flood exposure – users can easily, and quickly, undertake ‘what if’ investigations based on their own needs, see the impacts on their losses, and fully understand individual and portfolio risk profiles.”
Gary McInally, chief actuary, Flood Re, added: “I am pleased to see firms like JBA continue to invest in their flood data and modelling. Flooding presents a significant risk to the UK and is changing as a consequence of climate change, developing in complex ways that could have materially varying impacts across different communities in the UK.
”The changing climate means that access to up to date and detailed data will become increasingly important as organisations seek to effectively quantify and own their view of flood risk.”
”High-quality, flexible models have a major role to play in building the understanding of that risk to inform risk management today and the building of resilience for tomorrow.”
The data also shows that property level protection has the potential to make a huge difference – raising individual property defences for all residential properties in the UK could potentially reduce losses by half.
The largest estimated annual average losses for residential properties are seen in the Hull postcode area (6% of total estimated UK losses) followed by Bristol, Glasgow, Twickenham, and Slough. Other high loss postcode districts occur in and around the Thames.
The JBA UK Flood Model is underpinned by the Oasis Loss Modelling Framework and is accessible on multiple platforms.
