Bulb Smart Tariff

In general, I think that, without having smart meters installed, it'd be quite difficult to work out exactly how much you use when, and how much you'd save or lose with that tariff.  However, a unit used during the 3-hour peak time would cost 28p more than the current tariff.  That's 14 times more than the 2p you'd save on the current tariff during the 12-hour off-peak period.  And about 5 times more than what you'd save during the 8 hour night-time period.

Unless you were out of the house between 4pm and 7pm, or used a lot of electricity overnight, my gut feeling is that you'd be very hard pushed to make a saving switching to that tariff.  If you did use a lot of electricity overnight, an Economy 7 tariff might give you bigger savings?

My only potential use of electricity overnight (other than lighting) is for a battery electric vehicle at some time in future. The bulb overnight rates are not good in that respect. Not sure of E7 has any restrictions on use (e.g. for heating only)?

Some legacy tariffs had several registers, some of which were for heating circuits only.  But with E7 all usage is at the lower rate during the specified hours.  However, smart meters accommodate block tariffs.  Just as they can make tea time use prohibitively expensive, the smart meter tariff can make the p/kWh rate increase the more you use.  It's an EV detector !

Doesn't sound much use to you, then.  If you did get an electric car in the future, you could look for a different tariff then.
