Hi Steve
I am not surprised that the call centre staff could not help, although that is no excuse for being rude and hanging up, this is not something they are normally asked. As you say it is probably something of interest to more people as energy costs increase.
Are you sure your TV uses 210w on standby? How old is it? EU regulations introduced in 2010 and updated in 2013 should mean that no device in standby should draw more than 1w:
"On 6 January 2010, the European Commission's EC Regulation 1275/2008 came into force regulating requirements for standby and "off mode" electric power consumption of electrical and electronic household and office equipment. The regulations mandate that from 6 January 2010 "off mode" and standby power shall not exceed 1 W, "standby-plus" power (providing information or status display in addition to possible reactivation function) shall not exceed 2 W (these figures are halved on 6 January 2013)."

So with those regulations in mind the 360 shouldn't draw more than 1w, at least when in Eco mode. Having said that the box will need to "wake up" to perform recordings which will increase power usage.
I have found this page which shows power usage of previous Virgin TV boxes:

In addition to missing updates when turned off you would also miss updates to the channel guide and any recordings scheduled for when the box is off. That last one is probably obvious, but I believe some versions of the 360 in other countries have cloud recording options which would not require the box to be switched on.
