[2] Reigate Heath Windmill was built c.1765, although a mill was marked on maps dated 1753 and 1762.

In 1880, the roundhouse was converted into a chapel of ease to St Mary's Parish Church, Reigate, the first service taking place on 14 September 1880.

Recommendations made included the replacement of the weather beam, which had been penetrated by rot to a depth of at least 3 inches (76 mm).

Reigate Heath Windmill is a post mill with a single-storey roundhouse.

It originally had four common sails carried on a wooden windshaft, with the stones arranged head and tail.

It was last worked with four double patent sails carried on a cast-iron windshaft, with the two pairs of millstones arranged side by side in the breast of the mill, driven underdrift by spur gearing.
