Several flashes were created in the 20th century by subsidence after natural brine pumping in the area, some of which form part of a Site of Special Scientific Interest.

[10][11] A prisoner-of-war camp was located at Donkinson's Oak, near the southern edge of the parish, during the Second World War,[8][12] and there was a heavy anti-aircraft battery near Bottoms Farm in 1940–41.

[6] Natural (uncontrolled) brine pumping at nearby Elworth, Ettiley Heath, Wheelock and elsewhere in the Sandbach area occurred from the 19th century, increasing sharply after the First World War, and was associated with subsidence in Warmingham and the adjacent parish of Moston from the 1890s.

[6][8] A finery forge or smelting furnace was established on the River Wheelock north of the village in the mid-17th century, one of a handful in Cheshire at that date.

[21] The former corn mill was adapted to grind coconut shells for manufacturing plastics, and aircraft parts were made there during the Second World War.

[22] From 1974, the civil parish was served by Crewe and Nantwich Borough Council, which was succeeded on 1 April 2009 by the unitary authority of Cheshire East.

The Northwich Halite Formation, a Triassic salt field, underlies the civil parish, with the 170–240-metre-thick salt-bearing layer lying around 180–250 metres below the surface.

[26][27] In the area of Hill Top and Hole House, sandy soil overlays red clay, with the base rock being Triassic sandstone–mudstone.

[36][37] Since 2003, EDF has stored natural gas in underground cavities created by dissolving salt near Hole House Farm, with a total storage capacity of 75 million m3.

[42][43] The base of a medieval stone cross, dating from around 1298, survives in the churchyard; it is listed at the lower grade of II, and is also a scheduled monument.

[6][33][46] The oldest surviving building in the civil parish, Church House, dates from the late 16th century and is listed at grade II*.

[42][47][48] One former resident was John "Rebel" Kent, a supporter of Charles Edward Stuart ("Bonnie Prince Charlie") in the Jacobite uprising of 1745.

[50][51] Warmington Grange, off School Lane, is a grade-II-listed former rectory dating from the early 19th century, which served as a club and restaurant from the 1970s until 2005.

[8][42][52] The village maintains the tradition of holding Warmingham Wakes in early May; the event is now used to raise money for St Leonard's Church.

The West Coast Main Line railway runs north–south for a few hundred metres in the south-west corner of the parish, between the Crewe and Winsford stations, and is crossed by a footbridge.

[57] For secondary education, the civil parish falls within the catchment area of Sir William Stanier School in Crewe.
