Can you change a single rate smart meter to Economy 7 after it's been fitted?
Earlier this year I had a standard rate smart meter fitted. Since then I have bought a plug-in electric vehicle and I think it may be more economical to charge at 'Economy 7' overnight rate.
I have two questions......
1) Is it possible to retrospectively change a smart meter to dual rate mode?
2) If yes, what are the current costs for each rate?
Many thanks for your help.

Great question to ask about the possibility of updating your Smart Meter to a dual rate function. Bear in mind that Economy 7 has a cheaper off-peak (night time) rate and a more expensive peak (day time) rate. This means that Economy 7 is generally only best if you have night time storage heaters and/or an immersion tank that works on a timer. These appliances use a lot of power in the off-peak hours.
You can find out more about Economy 7 here:
Single Rate to Economy 7
Unfortunately, we don't currently have the functionality to change Smart Meters from Single Rate to Economy 7, or vice versa. If this ever becomes available we’ll update the Forum to let you know.
Economy 7 to Single Rate
Although we're unable to physically change the functionality of meters right now. We can put you on a single rate plan without changing the meter. We’d simply take both sets of readings and charge the total usage on one flat unit rate.
