If bulb have their smart tariff when are the time zones for the various rates?

There is a bit of Intrest I have with bulbs smart tariff. I was wondering when the hours are for the various rates, do I have to have a smart meter or do they simply offer a gadget which monitors energy use of a time of day like in the smart meter trials?

You have to have a smart meter. Times and prices can be found via the link above.

Cheers, I’m not sure it will save me money. As most of my electricity use is during peak hours.
