The Environment Committee has released figures warning Londoners of how 'at risk' their homes are to the flooding that has swept the UK.
More that 14,400 homes were categorised as 'high risk' in the capital.
Murad Qureshi, chair of the Environment Committee, said: "The figures we have obtained from the Environment Agency show far too many homes in London remain at high flood risk.
"The Prime Minister has said that money is no object, so it's time for the Mayor to cash in that promise and secure the funding necessary to protect those London homes."
Hillingdon, Hounslow and Harrow all feature in the top ten London boroughs with the most homes at risk.
