Why is the Fernox so much more expensive (5x) than the other?

I'm not really sure - Fernox comes in 4 litre size, and screwfix in 1
litre, but screwfix is alleged to treat up to 10 rads.

IIRC, Fernox at 4% will do my system twice , so there's a saving there.

I don't know about qjality - I have to assume they bothe work as
advertised, so that makes the screwfix one a better buy
