Good question this.
I bought a pair of 'work trainers' off them a couple of years ago and they were shocking / appalling quality; sole split, inner liner was glued in and moved down into the shoe.
I complained in detail (with photos) after a month.

CT were extremely good, full refund provided (no need to return shoes).
In the correspondence they stated;
'the manufacturer is one of our many shoe suppliers and we are reviewing quality with them at present'
From that, I suspect they have a few suppliers and I'm nearly 100% certain Barker is one (from another pair I have from them).
