Regular Landlord Law Blog readers may have noticed that I wrote a post on flooding a couple of days ago. In that post, I suggested that landlords and investors check the projected flooding maps before purchasing new property.
I was, therefore, interested when I saw a post here about a new housing development in Dagenham and thought it might be interesting to check that on the flood maps. Unfortunately, it looks as if, according to the Climate Central map, the Dagenham development seems to be in or on the edge of an area predicted to be below the annual flood level in 2050.
As you can see from the map above.
So maybe if you are considering purchasing any of those properties, you should think carefully.
It may not be a problem of course:
- The whole sea level rising thing could be just a big conspiracy theory and will never happen at all (although the weight of scientific evidence is against this)
- The actual building site may be further north than I thought and will therefore be safe (assuming the flood risk projections are correct), and
- It may be possible to protect the properties against flooding adequately with sea defences.
But it just goes to show that it is worth checking these things. ANYONE considering buying any property should check the flood risk potential very carefully. And pose questions about it in enquiries before contract.
Unless perhaps you are over 70 and do not have any relatives, you will wish to inherit the property. In which case, it probably won’t be a problem for you.

Not to take anything away from your general point, but I think the reason why the area is shown like that in the 2050 map is because the site of the development is already, in 2022, in an area of extreme flooding risk.
You can look at the current map on the Environment Agency and it shows that everything around Dagenham Dock station is already in ‘flood zone 3’ which is the highest risk level.

I think the map for 2050 shows the gradual expansion of the risk area and probably also there would be an increased risk of flooding and extreme weather events.
So why are they building all this housing in an area known as a flood risk? They will probably be uninhabitable by the end of the century.
