[2] By the mid-19th century, this arrangement was deemed inadequate, and civic leaders decided to commission a dedicated corn exchange on a site to the east of the Sheriff Courthouse.

[1] The use of the building as a corn exchange declined significantly in the wake of the Great Depression of British Agriculture in the late 19th century.

[6] In June 2014, the management of the building was transferred from East Lothian Council to the newly formed Haddington Community Development Trust.

[7] An extensive programme of refurbishment works, undertaken by Maxi Construction at a cost of £800,000 to a design by Summers Inman, started on site in spring 2019.

[10] After the work was adapted to allow the Brunton Theatre Trust to use the corn exchange for theatrical performances,[11] the building re-opened to the public again in October 2023.
