It's 21-69 isn't it, which is 49 channels, but close enough.

The old ONDigital boxes did use to warn that it might take 20 minutes
to do the scan although it never did.

Well given that the UK muxes transmit a network table you only have
to find one frequency by scanning and you can then locate the others
using the network table so maybe they do that?
