Our history:

Thames21 developed from a partnership programme supported by Keep Britain Tidy, the Port of London Authority, the Environment Agency, Thames Water, British Waterways, The Corporation of London and 19 local authorities. The charity is now independent, and is funded by a wide variety of charitable trusts, companies and public funding. It has a growing and diverse programme of water improvement projects across London.
