More than 1,000 privately owned flood defences protecting some of England’s most at risk towns and cities were found to be in a ‘poor’ or ‘very poor’ condition by Environment Agency inspectors last year.

According to the latest available data 28% of all flood defences defined by the government as ‘high consequence’ are in private hands and that there is no public record of who owns this vital infrastructure. These defences range from flood walls and embankments to outfall pipes and culverts – underground pipes that run below roads, railways or other property.

The new investigation, published with The Guardian, reveals that there is little oversight over these privately owned defences, with local authorities often not knowing who owns or maintains these assets in their own towns and cities. We have also learned that while the Environment Agency has powers to do emergency work on private defences if life is at risk, it finds it hard to make landowners play ball.  

All we can really do is ask nicely. We don’t have out and out powers to make somebody actually fix something

The revelations come weeks after the agency warned hundreds of people could die in floods in the UK if stronger measures are not taken to prepare for the impacts of climate change. 

Data obtained under Freedom of Information rules showing inspections in 2019/20 shows that ‘high consequence’ private assets were twice as likely to be in poor condition than those maintained by the EA, with 8% or 1,109 private defences rated as subpar. ‘High consequence’, according to the agency, means defences “that contribute to managing flood risk in a location where the consequence on people and property of an asset failing is high”. Defences are inspected and then rated from conditions 1 to 5, with 1 meaning ‘very good’ and 5 ‘very poor’.

By mapping private defences, using data provided to us by the agency, and overlaying this with materials shared with us by Guy Shrubsole as part of his Who Owns England? project, and documents from Land Registry, Unearthed has worked to build a picture of who owns poorly rated defences across the country. 

Responding to our investigation, Olivia Blake MP, Labour’s Shadow Minister for Nature, Water and Flooding said the government must do more to ensure private defences are up to scratch.

“As our winters get wetter, the climate emergency will put flood defences under greater strain. The government must act to ensure there are clear responsibilities and adequate measures in place so that any flood defences which are privately owned and critically important to the protection of the public are properly inspected and maintained,” she said.

A sinkhole in Sheffield

The poor condition of some privately held defences threatens to undermine government efforts to increase protections against climate change across the country. 

In January 2017, a sinkhole swallowed up two spaces in the car park outside the Decathlon store in Sheffield city centre. The sinkhole was caused by the collapse of a culvert — or underground pipe — owned and managed by the retailer, which contains the Porter Brook, a small river concreted over in Sheffield’s industrial heyday.

Four years after the collapse, our data shows the defence was still classed as being in “very poor” condition by the EA, one of 36 subpar privately owned defences in the Steel City.

James Mead, the flood and water manager at Sheffield city council, told the Guardian and Unearthed that Decathlon had been warned before the sinkhole that it needed to repair the culvert, but hadn’t. He added that despite being shored up with a steel girder as a temporary fix the defence is “still not really up to scratch.”

Mead’s powers are limited to force Decathlon to do the work needed to improve the culvert. “All we can really do is ask nicely,” he admitted. “We don’t have out and out powers to make somebody actually fix something.”

Decathlon UK said it repaired the culvert “at considerable cost” after the 2017 sinkhole, before uncovering the river to encourage flora and fauna. Heavy storms in February 2020 caused the collapse of part of the culvert wall, which the company again paid to be repaired.

“The culvert is now safe and we are continuing to monitor this situation,” said Decathlon’s regional property manager, Luke Fillingham, adding: “We’re pleased to say that the river channel has never been blocked and is now in better condition than when we originally purchased the land in December 2010 thanks to the work we have undertaken.” Further repairs are planned for 2022.

Also in the centre of Sheffield, a city hit by dramatic floods in the winter of 2019, the EA data shows a ‘very poor’ defence on land owned by the financial services giant Legal & General. Another is on land owned by Birmingham-based property developer Hortons Estate. Neither Hortons nor Legal & General responded to requests for comment.

At the city’s main train station, the River Sheaf passes beneath the terminal in a culvert that was rated as being ‘very poor’ in 2019/20. Network Rail owns the land.
