The wording to my mind suggests that this would be a Premium Rate number.

I think their wording is just "toll" as opposed to "toll-free 0800" so
it's a chargeable call, but not a premium rate, so depending on what
call bundles/minutes you have, chargeable doesn't necessarily result in
you being charged ...

But it appears to start 020

yes, it's just a normal London number, charged like any other 01/02/03 call.
