Oil v Off Peak Electric Radiator

Hello, first time positing :)

Recognising everything could change in the next few days/weeks, I'm after some advice. We have oil central heating, newish Worcester combi, 3 bed 1970's terraced house. Assuming oil is around 95p a litre. We have an EV tariff for electricity with a current rate of 8p kwh between 2am and 6am (35p peak). Ive been looking at moving my energy use to that time where possible in addition to charging the car.  

Is there merit in electric heating between those hours, thinking an electric radiator in the bedroom(s) as an example,

thanks for any help/advice

(also if any news about the off peak tariffs being protected would be welcome!!)

    There are roughly 10kWh in a litre of oil, so on the face of it your off-peak electricity is cheaper.
    However it's not worth heating a room of it doesn't need it, and the need for space heating between 2am and 6am is likely to be low.
    It could however be worth using your immersion heater to heat your hot water tank if you have one.
