You can boil and cool the amount required also if you have no other choice. 
Better than tap water if I'm correct

To be honest, I have always used tap water as a coolant dilutant and I live in an area that's has very poor water quality in terms of hardness.

Boiling won't do much unless you collect and cool the steam
When I had my six series bmw. Bmw said use tap water. Absolutely no requirement for specific water. I think they stated certain dh hardness requirement only. They also said you can use neat coolant if you want.

Don't use neat coolant, stick with 50/50. On its own, it doesn't provide good antifreeze protection, nor good heat transfer

Deionised water is more pure therefore is better then distilled.

They do a ready mixed anti freeze here, just pour it straight in. Never had an issue with the stuff.
I don't know but is it available in the UK as well?

I'd have thought 50/50.The window cleaner sold me deionised water.
What concentration?
The pink anti freeze is - 35°, the yellow anti freeze is - 27°.
Yoy can also buy mercedes type in blue also pre-mixed.

Used to buy it in Spain pre mixed,never worried about concentration it never got that cold,only put it in for corrosion resistance.
