The Blaby Union was established by the 1834 Poorlaw Amendment Act and was formed in February, 1836.
The Blaby Union included 22 parishes; Aylestone, Blaby, Braunstone, Cosby, Countesthorpe, Croft, Enderby, Foston, Freakes Ground, Glenfield, Glen Parva, Huncote, Kilby, Kirby Muxloe, Knighton, Leicester Forest East, Leicester Forest West, Leicester New Found Pool, Lubbesthorpe, Narborough, New Parks, Oadby, Potters Marston, Thurlaston, Whetstone and Wigston Magna.
The number and names of parishes in the Union would vary over time, up to 30. Later Additions: Braunstone Frith (from 1861), East Wigston (from 1894), Freakes Ground (1862-91), Glenfield Frith (from 1861), Kilby Frith (from 1861), Knoll and Bassett House (1861-1909), New Found Pool (1862-91), New Parks (from 1862).
In 1836, the Poor Law Commissioners authorised an expenditure of £4,400 on construction of the building which was to accommodate 350 inmates.
A new Blaby Union workhouse was erected in Enderby parish about 1 mile east of the village of Enderby in 1837. While it was being built, the existing Wigston Magna workhouse was rented and used.
After the abolishment of the Poorlaw Unions in 1930, the former workhouse became the "Enderby House County Home" providing accommodation mainly for the elderly and chronic sick. The old buildings were demolished in the late 1960s and replaced by modern premises for accommodating the elderly.
The Board of Guardians met on alternate Tuesdays at the Workhouse.
