Norwegian would

I once lived in Norway and I am sure there was an additive to put in diesel to lower its freezing point. Do you know if it can be bought here?

It's in already. But probably not quite enough for the low temperatures that some parts of Britain experienced over Christmas and New Year. The old additive, of course, was petrol. But it's a potentially explosive mix and not suitable for modern high-pressure common rail diesel injection pumps because it decreases the lubricity of the fuel.
