Harlow is a constituency[n 1] represented in the House of Commons of the UK Parliament since 2024 by Chris Vince, of the Labour and Co-operative Party.

It has above county-average levels of social housing,[2] underemployment and unemployment as at the 2001 census and the associated 2000 Index of Multiple Deprivation;[3] however, the new town has brought growth sustained in part by more commuting, with an increasingly-used and separate Mill station in the London Commuter Belt, and has seen a 9.2% increase in the number of apartments to 2011, which brings the proportion of the housing market made up by flats and apartments to 23.8%.

1974–1983: Harlow Urban District, and Epping and Ongar Rural District parishes of Magdalen Laver, Matching, Nazeing, North Weald Bassett, Roydon, and Sheering.

[6] 2010–2024: The District of Harlow, and the District of Epping Forest wards of Hastingwood, Matching and Sheering Village, Lower Nazeing, Lower Sheering, and Roydon.

[7] Further to the 2023 Periodic Review of Westminster constituencies, which came into effect for the 2024 general election, the composition of the constituency was expanded northwards to meet the electorate size requirements, with the transfer in from Saffron Walden of the two District of Uttlesford wards of Broad Oak & the Hallingburys, and Hatfield Heath.
