Re: estimated net "benefit" of £5.7bn by 2020

I used to work for a utility, so consider myself to have some knowledge of this, although it may be out of date now.
1. If you tell your supplier in advance of your move and take meter readings on the day you move, you can already do this. It was a regulatory requirement for suppliers to request meter readings when they become aware of a Change of Occupancy (COO) but most home movers don't tell them until after the event. Smart meters won't make a difference if no one tells the supplier of the change.
2. Many homes have meters located on the outside wall, so don't have to answer the door to a meter reader. There was also a health and safety requirement that meters were visually inspected at regular intervals. Smart meters won't change that.
3. Speedy reconnection means speedy disconnection in the first place. If your supplier wants to disconnect you, they have to obtain a warrant to enter your premises to do it. This takes time and money (hence the swingeing reconnection fees) so suppliers only use it as a last resort. If they can do it at a click of a mouse, then it will become far more common, and you can bet the reconnection fees won't get any lower.
4. As I said in point 3, you can bet the reconnection fee won't get any lower - they have you over a barrel as you can't just go to another supplier and ask them to connect you immediately, even if the reason for disconnection has been resolved.
5. I will concede that a sudden spike or change in consumption would be easier to pinpoint, but it still wasn't highlighted to the customer until she queried her bill, which could have been many (expensive) months after the the change. Now if you told me that the unusual consumption pattern triggered an alert on the system, prompting you to call her to check if there was a reason for the change, she could have taken action to put it right and save money. That would be a consumer benefit.
"The bottom line is, with smart meters you and everyone else will be billed accurately, for the power you actually use. You wouldn't believe the guesswork, fudging and compromises that go into reconciliation without them."
Actually, I would but, but this is a benefit for the industry, not the consumer, and there are other factors that cause inaccurate bills, that a smart meter won't fix, such as crossed MPANs.
