I expected frost damage to be more severe and thought that younger leaves would be more badly affected. It's also inconsistent damage across the same plant that made me think it was something else. thankfully, it's not something more serious!
Drought can also produce discolouration and most areas have had little if no rainfall for a good while, so make sure they're not thirsty, but they don't look it to me
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.

Lots of my plants look like that every year! They recover. I've had to water lots of shrubs and plants here - unheard of at this time of year
Hydrangeas, in particular, are tough as old boots. New foliage will grow too, and before you know it, they'll be looking grand.
Nowt to worry about Nick. A good drenching and a few warmer days will see them right
I live in west central Scotland - not where that photo is...
