SHARP is an independent crash helmet safety test funded and run by the UK government that puts ECE 22.05 approved helmets through a more rigorous extra test. It's a bit like the Snell test in the US, but arguably more real-world focused. While there are lots of differing opinions about how 'real world' some of the testing is, if you're trying to find the safest helmet for your money, then SHARP is about as good as it gets. At the very least, it puts helmets through the same test so you can see their comparative performance.
