And here you still have to mix half of the hydrochloric acid with water and (unfortunately order at least 5 liters), but they also have sodium chlorite on offer (unfortunately also only from 5 liters):
5L Hydrochloric Acid 9% and 5L Sodium Chlorite 25% www.abbeychemicals.co.uk/products-list-a-z
But I see that it seems not sooo easy to get the ingredients in the UK. I think this is related to the exit from the EU possibly. But that's just a theory, because that way things that are imported can be better monitored. And after all, no one is supposed to get healthy, and certainly not on a cheap way. But that is again just my opinion. I hope one of the sources or vendors works for you.
