The ONT is around 3-6 watts , so around a quarter to a half of your estimated consumption, £8 to £16 per annum or thereabouts , plus if anyone is sufficiently concerned about the cost , they could turn it off a night and back on in the morning so another third off so £6 to £11 per annum or around 3p a day …. It is reverse marketing speak to offer the annual cost when selling something , you say a whole years service for (even taking your maths at face value ) for 8.5p a day ( not £30 year ) but even presenting it in the most negative way as the annual cost as if it’s a one off payment hopefully no one is so financially strained that 3p a day or 8p a day or even £30 a year makes something unaffordable

Yes, I agreed with Chrisjp in principle but I thought I‘d run the maths as a proof and was surprised by the result.  Just wondered if I’d done something silly somewhere.  The old Nokia was quoted as 12v x 1A.

It’s the 24/7 that gets you.  Of course, overnight it’s going to be idling, as you said, so I supposed that would help.

I was just surprised at my own answer.

I guess it is a bit surprising but, even at the unrealistic £30/year, that's only £2.50/month, which is pretty insignificant against the typical £30-£50/month you pay for broadband service.
You can easily pay over £2.50 for just one cup of coffee in a high street coffee shop, so getting worked up about £2.50/month or less seems a bit over-agitated!
The other issue is Britain's extremely high electricity prices, which are 2 to 3 times more than typical European prices, and 4 times more than US ones. But that's another story....

After a lots of consideration and investigation 

I think in 2027 I will buy a 5/6G modern, A DV Phone and 5/6g  gsm alarm system.  With a couple off sim cards.  

No drilling, not much eletricals, no re routing wires or installing addational plug sockets and lower monthly costs not to mention more environmentally freindly. 

Over 10 years should work out cheaper.

Than adapting everything to run from Ont. 

Have 18 months to save £907  in todays costs. 

Sorry BT unless things change
