Smart Time of use Tariffs
Smart Economy 9 is a tariff with two rates for people with electric heating and a smart meter.
It’ll give you peak and off-peak rates for your electricity at specified times throughout the day.
Take advantage of nine hours of cheaper, off-peak electricity as it’s not just your hot water and heating that will be charged at the cheaper rate.
We’d advise trying to use more energy during the cheaper times where you can. Your nine hours are split across the day into three 3-hour blocks, so it should be easier to make the most of the cheaper rate.
Your cheaper, off-peak hours are the same if you have a Pay As You Go (prepayment) meter or a credit meter. They might vary by up to 10 minutes, but here’s a rough guide:
Off-peak times in GMT
- 3am - 6am
Off-peak times in BST
- 4am - 7am
- 1pm - 4pm
- 8.30pm - 11.30pm
Your smart meter’s In-Home Display will show the rate you’re being charged.
