cheapest time of day / night for energy use

It’s better for the National Grid and for the ecology in general not to use it between 5–7pm. But in terms of your money, I don’t think that there is a difference. The only exception is that if you are taking a part in Power Move, you can win some credit towards your energy bill.

OVO don't have any Time Of Use (TOU) tariffs except for the likes of Economy 7 etc so the cost is the same whenever you use power. However, as ​@costeek said, it best to minimise usage during the peak. You can get a reward for minimising your use during this time so look for the Power Move initiative in the app or web page.

Morning ​@SueB and a warm welcome to the OVO Forum community 😁.

Thanks for your post - I can see you’ve already been answered by ​@costeek and ​@Peter E. Do you have an Economy 7 tariff (split rates for peak and off peak (day and night))? If so, we can let you know which time the meter switches to the off-peak rate.

If you’d like more info on Power move, as mentioned above, you can find out more on our website, and in this Forum thread:

Hi Ben

No we don’t have a split tariff contract and I already signed up for the power moves

I was just wondering outside of 5-7 if there were any other cheaper times !

Gotcha - in that case you’re on Flat Rate so the rates are the same 24/7 - you just get rewarded if you move usage outside the 5pm to 7pm slot.
