SuperValu outlets tend to be larger than the convenience shop formats used by many other symbol group retailers such as Centra, Gala and Spar, and the larger SuperValu units are on a par with full-service supermarkets.

The supermarket was founded on 27 June 1968 (1968-06-27) out of the larger outlets in Musgrave's VG chain (originally formed in 1960).

Wellworths-SuperValu was a trading name used briefly by Musgrave in Northern Ireland following its acquisition of small-to-medium Wellworths outlets in 1996.

[6] As a result, SuperValu became the second-largest supermarket chain in the Republic of Ireland by grocery spend.

[7] SuperValu's stores in Spain are branded as Dialprix, Musgrave's Spanish business.
