Thousands of Stockport households could be at risk from the impacts of flooding in the next 25 years unless action is taken, new research has shown.

Aviva's Building Future Communities report brings together the latest data to outline the risks that homes could face from multiple climate threats by 2050 and beyond, including flooding, subsidence and extreme heat.

Environment Agency data similarly suggests the number of properties at risk in England could rise to 6.1 million between 2040 and 2060, including a 66 per cent rise in the number of properties at high risk.

According to Aviva's analysis, urban and densely populated areas, including Manchester, London and areas of the North East, could be hotspots for surface water flooding in future due to the greater prevalence of hard surfaces, which can prevent rainwater from draining.

According to the report, some of the UK's most well-known landmarks, including Cardiff Bay, York city centre and Liverpool waterfront, could be vulnerable to flooding because of rising sea levels, heavier rainfall and more frequent weather events.

Using Aviva's data, the Local Democracy Reporting Service has broken down the figures in Stockport to illustrate the rising proportion of properties at risk from flooding:

Cheadle

• Number of households in constituency – 43,287
• Number of properties with river or surface water flood risk in 2025 – 8,412
• Number of properties with river or surface water flood risk in 2050 – 10,791
• Proportion of properties with flood risk in 2025 (%) – 19.4
• Proportion of properties with flood risk in 2050 (%) – 24.9

Hazel Grove

• Number of households in constituency – 44,660
• Number of properties with river or surface water flood risk in 2025 – 6,565
• Number of properties with river or surface water flood risk in 2050 – 8,682
• Proportion of properties with flood risk in 2025 (%) – 14.7
• Proportion of properties with flood risk in 2050 (%) – 19.4

Stockport

• Number of households in constituency – 52,128
• Number of properties with river or surface water flood risk in 2025 – 7,419
• Number of properties with river or surface water flood risk in 2050 – 9,776
• Proportion of properties with flood risk in 2025 (%) – 14.2
• Proportion of properties with flood risk in 2050 (%) – 18.8

Jason Storah, CEO UK & Ireland General Insurance, Aviva, said: "In the UK we have seen the impacts of our changing climate and this year is no exception.

"Record temperatures, wildfires and flash flooding have affected lives across the globe and it is clear that action is needed to adapt to the increasing frequency of these events.

"Our Building Future Communities report lays bare the risks that homes and businesses could experience by 2050.

"The findings are stark. Millions more properties could be at risk from flooding, with rising temperatures, increased urbanisation and inadequate drainage exacerbating the risks in future."
