It cant be limescale as it still does it with a brand new kettle.

no it is "nucleate boiling" where tiny particles of steam vapour start to form in the water as it nears boiling point.
This makes it less permeable to light waves. As the temperature rises further circulatory currents will be induced in the water. A phenomenon called "film boiling" then occurs whereby the steam starts to form along the surface of the elements and escapes upwards in large bubbles- the characteristic "boiling" effect.
The presence of limescale is immaterial.

that doesn't happen in most modern kettles...
you could have limescale deposits - Uck...
more than likely you're using an old kettle? air gets mixed in with the water, microscopic bubbles, after a minute the water should become clear again, if not, clean/replace your kettle!

I think its the limescale. I've just arrived to London and before that, I've never seen "misty" boiled water! When I boil tap water it turns misty, but if I filter it in the "Brita Jar" beforehand, it doesn't turn "misty".

It is actually aerated. That means what you are seeing is tiny, tiny air bubbles in the water.
The way to test this is to pour it into a cup or glass and see if it clears. It will, given a wee moment.

Its air in the water. we get it in our sink sometimes
