> it's a device that the PR suggests that it helps you save energy and costs. I think being able to see your usage broken down to more than one reading per quarter can definitely help. You can then change your behaviour and see the improvements very quickly. One product many of the companies hand out with smart meters is something that sits there and tells you how much you're using right now. I can easily see that making people realise just how much they're using while not realising it, and turning some things off. > but be smart and cautious as some very energy efficient rated devices like new electric kettles and vacuum cleaners consume less power by using less Watt which means physically it takes longer to boil the water or the vacuum cleaner is less efficient as the engine is less powerful and it takes longer to clean your home. While you do need to check, you can definitely get lower powered kettles and vacuums (particularly the latter) that are as good or better. The EU has come around to regulating vacuums because many were just putting uselessly big motors in that did nothing really helpful for actually cleaning, but used loads of energy since people see a higher power and think it's automatically a better vacuum.
