Need a smart meter for the tariff below, but it does give 4hour overnight @ 5p and a cheapish peak price
From their web site, they will fit the meter.I’m not changing but might suit some.
A peak unit price – the price you’ll be charged per unit of energy you use most of the time, between 4.30am and 12.30am. (This varies a little depending on where you are in the country, but usually hovers around 13-14p/kWh)
An off-peak unit price – what you’ll be charged per unit of energy used between 12.30 am and 4.30am. (This is 5p/kWh, no matter where you are)
And a standing charge of 25p/ day.
