Flint & Neill is a firm of consulting civil and structural engineers based in the United Kingdom. Flint & Neill was established as an engineering consultancy in 1958,[2] and specialises mainly in the design, analysis, construction and maintenance of bridges, although they do also provide structural engineering services for other structures including buildings.

The firm is a subsidiary of the Danish COWI Group, and forms part of their Bridge, Tunnel and Marine Structures Division. On 1 January 2017, Flint & Neill rebranded as COWI.[2]


Flint & Neill was formed in 1958 as a partnership by Tony Flint and Tony Neill. In December 2008, the firm was bought by COWI, a Danish consulting engineering firm, and became a limited company.[2]

In January 2017, Flint & Neill merged with Donaldson Associates to form COWI UK Limited.
