The seat was created for the February 1974 general election, primarily from part of the abolished constituency of Chigwell, together with parts of the abolished constituency of Epping, which was notably the seat held by Winston Churchill from 29 October 1924 – 15 June 1945.
When Epping Forest was first created, it was more favourable to the Conservatives than the old Epping seat, as it lost the new town of Harlow (part of the old Epping Rural District) and gained the more Conservative Chigwell Urban District. During the Thatcher period the Labour Party's vote was crushed. Even though the Liberals managed to move into second place, their vote did little more than follow national trends and as soon as 1987 their votes dropped away as well.

The majority of the new constituency, comprising the Urban District of Chigwell (incorporating Buckhurst Hill and Loughton), had previously been part of the abolished constituency of Chigwell. Remaining parts had previously been in the abolished constituency of Epping.

The constituency was created in 1974 from the seats of Epping and Chigwell — both of these (then one constituency, Epping) were represented by Winston Churchill throughout his tenure as Prime Minister during World War II. The Conservative Party has won in Epping Forest in every election since the creation of the constituency. The previous MP Eleanor Laing, was Deputy Speaker of the House from October 2013 and Chairman of Ways and Means from 2020 until 2024.
