I've just caught 3 caterpillars for a closer look. They do look like the Scarlet Tiger Moth caterpillars https://butterfly-conservation.org/moths/scarlet-tiger so I may have to apologise to those that have been squished.
Large White butterfly caterpillar does look similar, your honour! https://butterfly-conservation.org/butte...arge-white
Thinking about it, all the host plants have been near the shed where I see the Moths every year. I feel really bad now.
