Never applied to us though as we have smart (ha) meters.
Oooh! We do love embracing new technology. But it has to be on our terms. First rule is it must be life-enhancing, not enslaving.
The idea of plotting real-time energy consumption data has some appeal; although like DSL line statistics, it's an interest that could soon wane!
My Aonghas is contemplating a homegrown 'smart meter' and maybe even a smart meter wrist-watch (!)

A DIY 'smart-meter' from simply swapping the MCB(s) / main isolator switch in the Consumer Unit for a WiFi-connected circuit-breaker module. About £20 - £30.
Supporting all of the features in an ordinary 'smart meter' - real-time load sampling, total energy consumption to date, and potentially more, e.g. an early alarm system detecting earth leakage, brownouts, etc.
But without all of the BigBrother surveillance in the supplier's own 'smart meter'. No risk of remote hacking either; fully isolated from BigTech.
And no gouging us with 'up to' 48 different 'smart' tariffs charged throughout the day. i.e. "surge pricing". e.g. Boil a kettle at 3pm and pay 15p/kWh. Boil it at 6pm and pay 95p/kWh.
Which is what UK energy regulator Ofgem is proposing for a smart meter regime to launch in 2025. Good rant on that from

If only it were so simple. British Gas (Centrica) became our statutory 'supplier of last resort' (SoLR) after the previous supplier 'ceased trading'. BG agreed to honour our old contract terms for x months. That earlier supplier was effectively nationalised in another state bail-out, like Bulb, before all of its punters, including us, were dumped on BG. We got no say in any of that. Besides, where are these cheap energy suppliers who refund their excess profits?!
For a good insight into the tumultuous energy sector, well worth a listen is retired City of London broker Mario Innecco (maneco64):
https://odysee.com/@maneco64:8Lately, Innecco focusses on the controlled demolition of the petrodollar system, behind the smokescreen of the engineered RU/UA 'crisis'.
Which many believe will precipitate the demise of the US dollar as the world reserve currency; to be supplanted, quite possibly, by a 'programmed' central bank digital currency (CBDC).
CBDC is a new technology, nothing short of Fintech Slavery, that I definitely do not want!
https://odysee.com/@BestEvidence:b/larry-carstens'-excellent-pandemic:eVanguard and BlackRock are separate firms/competitors. They are not related.
Vanguard is actually 'the largest shareholder of Blackrock'.. To paraphrase, 'He who holds the stock (or the commercial paper).. calls the tune'.

Please study that consumption data again. Previous estimates were generally corrected by actual customer readings, i.e. from me, when I remembered. Those readings are relevant whereas previous estimates are not.
Besides, usage over the last two years has been static, since the dwelling has been uninhabited since the plandemic launched in March 2020.
That fortuitous -59% 'underestimate' of usage from our energy supplier, on the eve of their 54% price hike, is outrageous!
Multiply that scam by their total customer base (seven million UK homes and business) and Centrica's undeserved excess profits must be eye-watering!
One wonders how often it pans out the other way?
How many customers get windfalls through their supplier
overestimating their usage, prior to a massive hike in the unit price? How's about none?! LOL!
