@Transparent gives some great advice as to what to consider before you request a change from a single to a dual rate plan, @bojack10 -
1: you have a 4-terminal meter with all of your house connected to the same output terminal pair. The meter simply changes the actual rate that you pay between midnight to 7am. In this scenario the ‘daytime rate’ is higher than the Standard tariff paid by other customers, so you need to do a quick bit of maths to ensure it’s worthwhile running the house on E7 at night.
Understandably you’re looking for the easiest and quickest way to move on to a dual rate plan and access a cheaper night rate if this is when you use most of your energy. Checking the details of your meter, as an S1 meter we don’t currently communicate with, a switch to OVO whilst your meter is still a single rate meter may not be the best solution, to be transparent about it!
If my theory is correct and you’re already S1+ then you might be able to switch now and have OVO control your meter just like an S2. I think it’s best to see if my theory is correct first though. If it is, you might be able to get proper Economy 7 immediately. :)
Ever the optimist, @Blastoise186!
Unfortunately, we don't currently have the functionality to change Smart Meters from Single Rate to Economy 7, or vice versa. This is something we are looking to make possible in the future and we’ll keep you posted with any further updates here on the Forum!
Economy 7 to Single Rate
Although we're unable to physically change the functionality of meters right now. We can offer an Economy 7 to Single Rate plan! This means you’ll be paying the same rate for each register.
If this is something you’re interested in, please get in touch with our Support Team.
Single Rate to Economy 7
At the moment as it stands, there's no way for customers who wish to switch their Smart Meters from Single Rate to Economy 7.
Hope this helps you work out the best option for you - let us know what direction you decide to take!
