In Lidl, Aldi, Euro family etc is the cheaper content in black, plastic containers (looks close to a gallon)
a bleach of sorts and does anyone know roughly the concentration.

The 5ltr containers have the same contents as the 1itr containers, yes it is a bleach generally termed as 'hypo' and commonly used for cleaning and disinfecting home and commercial premises. The concentration shown on the side of the container is <5% To use, if you want a 10% solution add 1 part hypo to 9 parts water.
