I’ve never seen an unvented tank (or any tank) in the UK installed on a drip pan. This is pretty common in the US though. As someone who’s unvented tank in the loft leaked (through a cracked immersion element unit) and flooded a bedroom below it seems like a simple safety precaution...
Is there some good reason why this isn’t common practice. Plumbing the outflow from the pan into an overflow like the tundish is plumbed into seems pretty straightforward.
