Asset 1

Living on the edge.

A house by the coast may sound like a dream, but the prospect of your home falling into the sea is a nightmare. And for some, it may soon be a reality. Coastal erosion threatens households, industries, and infrastructure in many places around the UK.

Environment Minister Thérèse Coffey stated: “One in six people in England are already living in properties at risk of flooding”. A combination of coastal erosion, rising sea levels and climate change all contribute to this nationwide issue.

Our map shows how some of the most at-risk places are set to be impacted by this creeping threat

You can also take a look at data for the 30 most at risk locations to see if your home is in trouble. Find out about flood insurance for your home if you live in a flood risk area.

We looked at 10 of the areas most at risk from coastal erosion according to data on England and Wales from the Environment Agency. Click on each area to find out how much the coast is set to erode in the future.

We’ll also tell you how many houses are in the area and what the average insurance premium is. You can even see how much land we could lose to the sea over the next 20, 50, and 100 years without intervention.

Disclaimer: Coastal erosion estimates are based on data from the Environment Agency, which has predicted these figures based on a 50% confidence level if there is no active intervention. Average rebuild costs are based on Confused.com data from January to March in 2019. Rebuild costs not included in Confused.com data were based on propertydata.co.uk data. Average home insurance premiums, which are taken from Confused.com data from January to March in 2019, cover joint buildings policies and are based on yearly payments

Any claims made within this asset about specific buildings or sites being affected by erosion are purely speculative due to data being accurate to a post code level. Animations and claims do not take into consideration specific detailed council plans, and animations represent average erosion in that given post code.

TOWN

AREA

Happisburgh, a town just under 20 miles away from Norwich, is the most at-risk area of coastal erosion in the UK over the next 20 years. There are 10,377 houses in the NR12 postcode, which includes Happisburgh, Waxham, and the more inland towns of Coltishall, Stalham, and Wroxham. You’d pay an average of £295,182 for a property here. And the average home insurance premium (buildings and contents) is £170.02. Here the shoreline could erode back into the town. The figures below show how far back it’s expected to move.

This could mean that houses and holiday lets close to the shoreline could fall into the sea. If residents’ houses were destroyed beyond repair, the data shows that the average rebuild cost for houses in the postcode area is currently £229,816.

Up to 20 years: 97 m
Up to 50 years: 150 m
Up to 100 years: 200 m
