The existing mill dates back to the 18th century, but was extensively rebuilt in 1864.
[1][2] The mill, along with its aqueduct, has been Grade II* Listed since 1987, primarily for the surviving machinery which dates back to the 19th century rebuild.
[2] Following the 1864 rebuild, the Lockyer family became tenants of Clapton Mill in 1870 and later purchased it in 1901.
[5] The new owners made plans to return the mill to commercial use, while also attracting visitors as a working museum.
In 2006, a hydro-electric turbine was installed at the mill to generate green energy.
