Flood Risk and Flood Defence Infrastructure: North-west England

Andrew Cooper Excerpts

Tuesday 18th November 2025 Westminster Hall

[Sarah Hall (Warrington South) (Lab/Co-op)]

I beg to move,

That this House has considered flood risk and flood defence infrastructure in the North West.

It is a pleasure to serve under your chairmanship, Dr Murrison. I asked for this debate because people in Warrington South are worn down by the constant risk of flooding. It shapes their day-to-day lives far more than most people realise. We need a frank conversation about what is happening and what needs to change. For my constituents in places such as Dallam, Bewsey, Sankey Bridges and Penketh, this is not about distant risks or statistical forecasts. It is about the reality of waking up to flood alerts, checking river levels whenever the rain starts to fall, and wondering whether the water will stop before it breaches the banks of the brook.

I have lost count of the number of people who have told me that they cannot sleep when heavy rain is forecast. Parents have told me that their children get anxious when storms are mentioned on the news. Older residents tell me that they keep a torch by the bed, just in case. It is those small details that show just how deeply flooding affects people long after the water has gone. That is no way to live. No family should have to brace themselves over and over again for another clean-up every time the water rises.

In Dallam, we now see a situation where people are effectively marooned. When Longshaw Street floods and the Hawley’s Lane bridge goes under, Dallam becomes an island. People cannot get to work, get their children to school or leave their homes safely. Older residents who rely on adult social care are cut off. Patients at Lea Court are placed at additional risk because the access routes simply disappear under the water. Those are serious safety issues. No community should find itself trapped because the infrastructure around it can no longer cope.

From Merseyside to Greater Manchester, and Warrington in between, communities are facing the same issues: extreme rainfall, overwhelmed watercourses and schemes that take too long to materialise. The north-west is carrying a growing share of the national flood burden. Our region contributes significantly to the national economy. We should not be left fighting year after year for the basic infrastructure needed to keep homes and businesses safe. For too long, flood resilience in the north-west has relied on a patchwork of bids, lobbying rounds and one-off pots of money. That is not a strategy. It leaves communities vulnerable, stuck in a cycle of uncertainty.

On new year’s day, I was out across Warrington South in communities devastated by flooding, down Higham Avenue, Tavlin Avenue, Longshaw Street and Southworth Avenue. Some families were only just returning to normality following the Storm Christoph floods in 2021. Others were already exhausted by the constant cycle of rain, flood alerts, worry and clean-up, and it has not stopped there.

[Andrew Cooper (Mid Cheshire) (Lab)]

My hon. Friend mentioned Storm Christoph. Both Northwich and Winsford in my constituency flooded twice in an 18-month period, most recently during that storm. Our section 19 investigation found that although Northwich’s flood walls held, the ancient Victorian combined sewerage system was not up to scratch. Does she agree that when we talk about investment in flood defences, it is about not just flood walls, but investment in our sewerage infrastructure?

[Sarah Hall]

I absolutely agree; my hon. Friend makes an important point.

In September, we came within inches of another major event. The emergency services set up a temporary command post, and we were preparing to evacuate homes again. Then, just last Friday, we had another flood alert, with modelling suggesting that we were heading for yet another breach. Residents can see what is happening: these events are coming closer together and they are becoming harder to predict, but none of that should come as a surprise.

I want to be clear that the areas most exposed to flooding in Warrington South are some of the most deprived, with some of the highest levels of disadvantage. They are the least able to shoulder the cost of repairs, the rising insurance premiums or months of disruption. Those communities are hit first and hit hardest, and they deserve the very best protection we can give them, not the uncertainty of waiting year after year for the infrastructure that they should already have had.

When I looked at an old Ordnance Survey map from the 1880s, I saw that the land around Dallam and Bewsey was clearly marked as liable to flooding, with mud flats shown across an area that is now full of homes. Much of the housing built in the pre-war and post-war decades went up before anyone talked about climate resilience or long-term hydrology. Those decisions were not malicious; they were just made in a different era. With the kind of extreme rainfall that we are now seeing, those early planning decisions are showing their limits. That history matters—it helps to explain why that area is so vulnerable and why modern infrastructure simply must catch up.

Nobody back then could have foreseen the level of rainfall now, but we cannot pretend that those planning decisions are not part of why we are here today. We have a responsibility to respond to the risks that are now so clear. This is not bad luck or a one-off winter; it is a pattern. The storms are heavier, the water rises faster and the ground saturates more quickly. Our infrastructure simply was not built for that pace or intensity of change.

People often ask me about dredging, clearing the gullies, reopening canals and maintaining the brooks. Yes, those things matter, and I will always push for better maintenance, but we need to be straight with our residents. Dredging, clearing gullies, reopening canals and cutting back vegetation cannot prevent flooding when we get an entire day’s rain in just a couple of hours. That is the scale of the challenge; no amount of clearing alone can keep the water back.

Flood events that used to be rare are now frequent. What used to be a slow rise in water levels can happen in the blink of an eye. The weather has changed, but the infrastructure has not. That is why the Sankey brook flood risk management scheme is so important. It is why I fought to secure the funding that finally allowed the outline design stage to begin. The contract has now been awarded and engineers are progressing the plans. Without securing that funding, we would still be talking about possibilities, rather than the engineers beginning their work. But I have to be honest: in the past, promises were made without a plan and people were let down. I will not repeat those mistakes. Sadly, even now, there are some making big claims about this scheme without understanding how complex it is. It is easy to say what people want to hear, but much harder to follow through and deliver. This is not a fast process and I will not pretend it is, but it is real progress after years of false starts.

My constituents are desperate, and they ask me the same question time and again: when will this actually be built? The honest answer is not an easy one. At the moment, construction is not due to start until 2029, with an expected completion date in 2032. For communities that have faced repeated flooding, that is a long wait. They understand that the scheme is complex and that it needs to be done properly, so that flooding is not simply pushed on to other neighbourhoods. But they also need reassurance that the project will not stall again because, right now, we still do not have all the funding required. There is an affordability gap that we cannot ignore.

In the north-west, we have already seen schemes fall behind when the funding picture is unclear. We cannot afford for that to happen here. Sadly, we all know that the Sankey brook scheme will not entirely remove the risk of flooding. With more extreme weather and a change in climate, that risk will always be there in some form. What we can do is take every practical step to protect the communities most at risk. We can identify the gaps, strengthen the early-warning systems and put better support in place while the scheme is being designed and built.
