Belkin make a number of surge protectors which offer a connected equipment warranty in the UK. Admittedly: financial protection, not data protection, but I felt it was worthwhile for the peace of mind.

Have they ever paid out on one of those, or is it like CAs who offer liability protection for their certificates carefully set up in such a way that they never have to pay out.

You should have data backups regardless, because there are plenty of ways to lose data that don't involve power surges.
