Just sent at a post office: it is called Royal Mail recorded 1st or 2nd
class, Signed for. This is the standard postal service with signature
and barcode scanning on delivery.

That's just normal mail with confirmation it arrived. It's no less
likely to get lost en-route.

But considerably less likely to be lost by the recipient.
