I'm just trying to establish where the recalled Atlas Kablo cable may have been fitted.
If you want specific installations, then it's too late.
Those who purchased it in 2010 and earlier are not likely to remember now, even assuming they actually chose a specific brand of cable at the time - plenty would have just purchased whatever was on the shelf with no regard as to who actually made it.
Any business records from 6+ years ago are likely already destroyed and it's desperately unlikely anyone with old records before then will be wanting to dig through them to establish if the cable they purchased was that brand. Even if they do and did, this assumes the brand of cable was actually stated on an invoice which in plenty of cases it would not be.
Even that doesn't confirm where it was installed, just that it was purchased then and probably used for installations shortly after that.
Any installed cables will be 99% concealed in walls, floors and similar. Inaccessible without dismantling and disruption, which no one will want just on the offchance that the cable is that particular one.
There is yet another problem in that some cables are not sold under the name of the manufacturer, but are repackaged and sold under different names. Smaller quantities being sold in DIY type shops for example - this cable:

Wickes' but they are obviously not the manufacturer of it.
