Standby power consumption

The 1 Watt regulation was part of the red tape "forced" on us by the EU, of course.

And that's a bad thing?

With the quotes I'm guessing at sarcasm

You guess correctly.

Awesome! 

What do I win?

Verdigris

A backhanded compliment!

Since October I've turned my tv and sky box (which for me is a freeview box) at the wall at night for the next 18-20 hour's.. for the last 4 months I've used 35-50kwh's less a month over the the previous 3 year's.

The sky box I have saved 20kwh's a month.
The tv says' 0.3 standby power consumption, but with 15-30kwh's unaccounted for It looks like it uses more than it's states. 
Either way I'm saving 45 kWh a month which is £7.50 a month on my current tarriff or £12.50 if I was on April's price cap tarriff... For me a significant saving....also 130kg c02 released bringing down my 👣

Maybe worth trying each through a plug-in energy monitor to track down the culprit.  The surprise I got was how things rated for 230V use more in the real world - kettle, toaster, heater

The device voltage rating just tells you the voltage range is it designed to work with, it isn't a limit, as the device takes what it is given by your supply when it comes to the input voltage.

The voltage you see displayed on an energy monitor is just telling you what the input voltage from your supply is at that point in time.

They are more forced to use than decide to use, they can't decide how many volts they want, they are just given it.

I suppose things fed through a power brick should still consume around the figure on the rating plate but plain resistive stuff scales with V² so can be a shock

My plasma GT60 is 0.3 W.  Another, older one is 0.2 W.
EU regs require all to be <0.5 W nowadays (and for a long time I think).

My old Foxsat-HDR PVR uses 1 W in standby.  A Freeview equivalent era (HDR-Fox-T2) uses 0.4 W in power saving standby (no aerial RF passthrough) or 3.8 W in normal standby.

A Sky Q box in standby is 20-25 Watts 'cos bits like wifi are still active (Eco standby <0.5W but takes longer to 'wake up').
Sky+ / Sky HD+ boxes are around 19 Watts with no eco mode.

Modern devices are generally lower power in standby than stuff even 5-10 years ago.

My washing machine uses 0.3 W "off" or 0.6 W if connected to my network (for its smart app comms) and a whopping 3 W if waiting to start a time delay wash (which I never use).  My tumble dryer also uses 0.4 W when "off".

So the BBC and other Journalists are, imho, barking up the wrong energy saving tree with TVs on standby.

Modem routers are likely around 4-5W in idle (24/7) and a little more if streaming to multiple devices.
Smart light bulbs may be up to 0.5W each... the bridge say 3 W...  Google mini uses 1.4-1.7 W.  Alexa Dot 3-4 W... 

Then you have fridges, freezers, lights (PIR), security cameras, doorbells, etc.,.

Rule of thumb:

1 watt of power, switched on continuously for a year, will cost £2 on your electricity bill, if your cost per kWh unit is 22.8p.

Adjust pro-rata for watts, hours per day, days per year, and tariff.

I have lost count of the number of posters on MSE complaining about their massive consumption of xx thousand kWh pa that state 'and I always unplug my TV when not in use.'
