Warning more homes will be uninsurable due to flood risk

Homes are being built today that could become uninsurable in the future due to the risk of flooding, the boss of insurance giant Aviva has said.

Amanda Blanc said the risk of flooding is "absolutely increasing", but based on current building patterns 115,000 new homes will be built in flood zones in the next decade.

"That doesn't seem to me to make sense. We need to think about where those homes are being built," she told the BBC.

About 6.3 million homes and businesses in England are at risk of flooding, according to the Environment Agency, and Aviva research found one in nine homes built between 2022 and 2024 are at medium to high risk of flooding.

Blanc told the BBC's Big Boss Interview podcast that England was "for sure" building homes that might be uninsurable at some point in the future.

"It's very well known where these flooding areas are. Let's think very carefully about homes that are being built."

Blanc said construction that borders those flood zones also needs a different approach.

"You can do all sorts of different things to your property to make it more or less vulnerable to flood," she said.

According to Aviva's research, nearly a third of new homes built in 2024 will be at risk of some flooding by 2050, and one in seven would be at medium to high risk of flooding as extreme weather becomes more acute.

Earlier this year the Met Office estimated that with current levels of global warming, record-breaking wet winters like the one experienced in the UK in 2023-2024 have gone from once in 80-year events to once in 20-year events.

The BBC has approached the government for comment.

Blanc said Aviva was "ready with capital" to invest in infrastructure, pointing out that the company already invests more than £100bn in the UK, £35bn of which goes into infrastructure, from hospitals to schools to windfarms.

"We've got that capital. We want to invest, we're a big UK employer. We want to invest in UK infrastructure. It provides good returns for our pension holders and for the members of those pension schemes," she said, but added detail was needed to turn it into reality.

Asked about the current debate about the pension triple lock, which means the state pension rises by the highest of either average wage increases, inflation or 2.5%, and whether the government is looking to change that, Blanc said it was not for her to say what should happen.

But potential lower annual increases to pensions if the triple lock is changed would have knock-on effects, she added.

"If you've got a lower state pension then you need a higher private pension, don't you? So you need to think about that balance," Blanc said.
