What time is electricity cheaper in the UK, it used to be 6 pm during the week and all day at the weekends but i am not sure if this is still the case.
Unless you have a 2 rate meter ("white meter" or "Economy 7" tariff) it is never cheaper, and is charged at the same rate 24/7.
You are unlikely to have an offpeak rate unless you have storage heaters.

I think it was cheaper in 1936. Your thinking ecconomy 7 heating and I think it was aroun 6 at night but it might have changed so it more expensive when every one is home.
