I'm in the process of moving my electricity supply to Octopus energy as I'll definitely save money on their agile tariff where prices are very low during the night (good for charging EV, dishwasher, washing etc)....sometimes you even get paid to use electricity when there is excess in the system!

Currently during the summer we have the oil fired boiler come on for an hour in the morning/evening to heat the hot water tank up. I'm just wondering roughly at what £/KwH is it cheaper to do it via electricity? It might work out cheaper to set the immersion to come on for an hour at 4am rather than be burning oil? ANyone know how i can work this out?

Btw if anyone is thinking about moving to Octopus let me know and i can share a referral code which gets us both £50 ;-)
