So if one is away from the house for some time, say on holiday or for work, the refrigeration/ freezer will not be restored and neither will the heating system function.
Added to that the Ovo meters are not interchangeable with other suppliers so one is not able to leave Ovo without additional problems.
If what I have described is correct why would anyone ever fit a Smart Meter?

If there is a power cut in your area, then you’d need to call 105 the powercut helpline number. To get your meters back on supply you would just need to press AAB on each meter using the keypad.
Take a look at this topic where you can see a list of suppliers who can communicate with our SMETS1 meters.
Hope this helps,
