Flood Risk: London

Debate between Felicity Buchan and Karen Buck

Wednesday 20th April 2022 Westminster Hall

[Felicity Buchan]

This is one of the rare occasions on which the hon. Gentleman and I completely agree. We need a comprehensive solution, which I will go on to talk about: we need a short-term solution, because my constituents are very anxious about this summer since most of this flash flooding has occurred in July, August and September, and we also need a long-term strategy. My constituents, like the hon. Gentleman’s, simply cannot live with this risk hanging over them.

[Ms Karen Buck (Westminster North) (Lab)]

I informed the hon. Lady that we would be seeking to make a brief intervention. I am grateful to her, and congratulate her on securing this debate. As she knows, I secured a similar debate in the autumn.

Insurance is one of the most worrying issues for residents in our parts of London, along with the difficulty people face in obtaining affordable insurance or insurance at all. There is a scheme, but it does not cover many flat owners in blocks of more than six properties. Does the hon. Lady share my concern that we need to do more to make sure affordable insurance is available, as the risks of flooding are, unfortunately, only likely to increase?

[Felicity Buchan]

I completely agree with the hon. Lady that affordable insurance needs to be available. Speaking from personal experience, as I said, I was flooded in 2007. My then insurance company did an amazing job of paying out to remedy the damage, but then said the year later that it did not want me as a client, so that is an important point.

Sometimes, I wonder why flooding in London does not attract more attention. When a member of the general public thinks about flooding, they probably think about flooded fields in Shropshire or coastal communities in Cornwall and Devon, but the reality is that flooding in London is a huge issue, and there are many reasons for that.

We have a Victorian sewerage system that was built for way fewer people. We have clearly seen climate change, with warmer air that can carry more moisture, hence more rainfall. We have also seen densification and concreting over in London, especially central London, so there simply are not as many places for surface water to flow. This is a very real issue; it is certainly one of the top issues in my constituency, and it will continue to be so, because the risks of these flooding events will continue to grow—because of climate change, as I have mentioned, but also because of population growth and the need for more housing.

I have set out the magnitude of the problem and the frequency of these events, and have said that we need short-term and long-term solutions, but it is worthwhile looking back at what has happened, because as I say, this has been going on for 20 years. After the devastating flood in 2007, Thames Water decided to put into effect a strategy to deal with the Counters Creek catchment area, which includes Kensington and Chelsea and Hammersmith and Fulham. Its proposal, which it put to Ofwat and which Ofwat agreed to, was for—in effect—a 5 km relief sewer tunnel, and to add lots of individual flood defence mechanisms to houses, called FLIPs. It was agreed that that should take place in the period 2015 to 2020, and the expenditure was going to be £300 million. It was all agreed to and the work was due to be completed by 2020. However, Thames Water decided not to proceed with that relief tunnel. Indeed, it said that one of the reasons for not proceeding was that the

“risk of hydraulic sewer flooding was much lower than we had originally thought.”

Clearly, that conclusion was wrong, given the devastating flooding that we had in 2021.

Thames Water was fined by Ofwat for not proceeding with this significant infrastructure scheme. It is now 2022 and there has been devastating flooding, so if it was the right scheme before the expenditure for 2015 to 2020, I need to be convinced of the reasons why it is not the right scheme now. I am not a structural engineer, but if it was the right scheme then, I think it is likely to be the right scheme now. Clearly, we can improve things—we should not be wedded to technology from 10 years ago—but if the conclusion was that we needed major infrastructure investment then, I think it is highly likely that we need it now.

Since the floods in 2021, Thames Water has appointed an independent review panel to investigate them, what caused them and how Thames Water’s assets performed. I welcome that independent review, but we need to make sure that it is not simply an academic analysis. We need to make sure that the review leads to concrete proposals and a plan and strategy that we can implement. That plan needs to be both short term and long term, because my constituents cannot live with this risk hanging over their heads.

Thames Water has also made £10 million available to install individual FLIP devices in the worst-affected properties in London. Of course, £10 million is welcome, but I really do not think that it will sort out the issues in London. This is not £10 million for a small bit of Kensington; it is £10 million for the whole of London. We need a lot more investment.

By its own admission, Thames Water’s response on the night was inadequate. Both Kensington and Chelsea and Westminster Councils had to get involved because Thames Water simply could not cope with the situation. I know that Thames Water has done an internal review, but it is very important that the processes are sorted.

I have outlined the problem, my concerns about the solutions offered to date, and my plea for better short-term solutions and a long-term infrastructure solution. I sought this debate, first, to highlight the issue and, secondly, to ask the Minister for her support in holding not only Thames Water but Ofwat and the Environment Agency to account. As I say, my constituents cannot spend the next 15 to 20 years with this hanging over their heads. If the right solution in 2015 was major infrastructure, I need to be convinced why that is not the right solution today.
