I have a very cheap fixed price deal with the controversial Outfox the Market supplier - just 10.1p/kWh - until August. Their standing charge is £13.99 a month, which is a bit steep, though. No exit fee. I've done some costing with estimated car charging costs, including 450kWh of annual phantom drain and additional consumption for cold weather consumption, averaging 0.4 kWh per mile over the year (not including phantom drain). Is that a realistic number? I've got a quote from Octopus Go and there is 4 hours of off-peak charging per day at 5p and the rest of the day it's about 14p. Their standing charge is about £7.50 a month. I've estimated annual 1000 miles of Supercharging, 7500 miles of off-peak charging at home and 1500 miles of peak rate charging. So I reckon our total electricity consumption figues mean we'll save about £70 a year with Octopus. A smart meter is required. However, Octopus are not fitting next-gen smart meters yet. I already have a first-gen smart meter originally installed by First Utility when we were with them, but - surprise - it didn't work as a smart meter when we switched to the Co-op and ditto with Outfox. It's not compatible with Octopus either. Octopus say they would change our 1st-gen meter for their 1st-gen meter and then when they start shipping 2nd-gen meters they would replace the meter they originally fitted with a new one. This seems mad to me, but I do like smart meter functionality. Should I go for it? Are there any other deals I should consider?
