Our work changed the company car scheme - now its a "sustainable" car scheme and open to all staff. I initially dismissed it as they looked expensive but when doing the maths properly, it worked out a little cheaper than what I was paying for my company car.
I took delivery of a Ford Kuga plug in hybrid last month. The gross payment for the lease is £590pm - but that is deducted before tax and NI, so I make a saving there of £248. When I then add the benefit in kind on of £102, it works out at £445 net each month.
I looked at Octopus but their customer service put me off just trying to get answers to some simple questions. I am with e-on - they had an EV tariff so I switched to that (not tied in) and my daily charge p/kwh increased slightly but I get an overnight charge of 9.5p p/kwh (which is for all electric - so have been using the timer on the dishwasher and washing machine where possible to capitalise on that as well). I had my annual figures from e-on and put them into a spreadsheet and made some assumptions on how often I would charge the car - my current tariff (on last years figures) was £145 - the new tariff increased that to £157. However, if I then factor in an assumption of how often I would charge the car per month, that should cost around £20pm, as opposed to £65 on my previous tariff, so should save me £36pm by switching (Octopus would have been another £11pm cheaper based on them figures).
