1885–1918

• The Sessional Divisions of Epping, Harlow, and Ongar; and
• Part of the Sessional Division of Dunmow.^[1]

Formed from part of the abolished West Division. See below for areas covered.

1918–1945

• The Urban Districts of Buckhurst Hill, Chingford, Epping, Loughton, Waltham Holy Cross, Wanstead, and Woodford; and
• The Rural District of Epping.^[2]

Gained Woodford from the abolished Walthamstow Division of Essex and Wanstead from the Romford Division. Lost eastern areas, including Chipping Ongar, to Chelmsford, and northern areas, including Great Dunmow and Hatfield Broad Oak, to Saffron Walden.

1945–1974

• The Municipal Borough of Chingford;
• The Urban Districts of Epping and Waltham Holy Cross; and
• The Rural District of Epping.^[2]

The House of Commons (Redistribution of Seats) Act 1944 set up Boundaries Commissions to carry out periodic reviews of the distribution of parliamentary constituencies. It also authorised an initial review to subdivide abnormally large constituencies in time for the 1945 election.^[3] This was implemented by the Redistribution of Seats Order 1945 under which Epping was divided into two constituencies. As a consequence, the new Parliamentary Borough of Woodford was formed from the Municipal Borough of Wanstead and Woodford (created from amalgamating the two separate Urban Districts) and the Urban District of Chigwell (previously a parish in the Rural District of Epping which had also absorbed the former Urban Districts of Buckhurst Hill and Loughton).

Abolition

The seat was abolished in 1974 following the Second Periodic Review of Westminster constituencies. The Borough of Chingford had been absorbed into the London Borough of Waltham Forest on its creation within Greater London and now formed the basis for the new constituency of Chingford within that Borough; the Urban District of Harlow, which had been created out of the Rural District of Epping, together with neighbouring parishes (now part of the merged Rural District of Epping and Ongar), formed the new constituency of Harlow; and remaining parts were included in the new constituency of Epping Forest.

Areas covered

Another general election was required to take place before the end of 1915. The political parties had been making preparations for an election to take place and by July 1914, the following candidates had been selected:

• Unionist: Amelius Lockwood
• Liberal:

This election was suspended by the Parliament and Registration Act 1916 (royal assent 27 January 1916), which was extended five times, due to the First World War. A general election was finally allowed in December 1918 after the war was over; but first, Amelius Lockwood was disqualified as an MP by being raised to the peerage in 1917, necessitating a by-election. The Liberals, in wartime coalition with the Conservatives and Unionists, did not oppose the Unionist candidate.
