Every constituency projected to be at greater risk, with many areas likely to be uninsurable * The flood-prone Worcestershire town being abandoned by insurers * Doors, drains and paving perils: protecting your home from flooding Millions more homes in England, Scotland and Wales face devastating floods, and some towns may have to be abandoned as climate breakdown makes many areas uninsurable, a Guardian investigation has found. New analysis from the insurance industry, seen by the Guardian, reveals the extent of concern in the sector, with bosses warning that large swathes of housing and commercial property in densely populated areas will be at greater risk. Every constituency in Great Britain is projected to have increased flood risk in future. In England, 69% of constituencies are likely to have an increase of more than 25% in the number of properties facing flood risk by mid-century. In Wales and Scotland, every area is projected to have a similar rise with many being much worse hit. Bermondsey and Old Southwark in London and Boston and Skegness in Lincolnshire are projected to have about 90% of homes at risk from river and coastal flooding by 2050 – the highest proportions in the country. Overall London and Yorkshire and the Humber collectively represent more than half of the top 20 constituencies affected by river and coastal flooding, highlighting that the east of England could be most negatively affected. Surface-water flood risk is likely to be particularly acute in dense urban areas, with 14 London constituencies ranked in the top 20 Bournemouth East shows the largest projected increase in surface-water flood risk, with its low-lying topography and inadequate drainage making it particularly susceptible. Over the past decade, 110,000 new homes were built in the highest risk flood zones, equivalent to one in 13 of the new homes built. Aviva calculates that if this trend were to continue, 115,000 of the government’s planned 1.5m new homes would also be in the highest-risk flood zones. Continue reading...
