For many electric vehicle drivers, charging at home is a crucial part of ownership. The convenience of plugging in overnight and waking up to find a fully charged car is familiar to a large number of owners.
Charging at home, whilst cheaper than petrol or public charging, means that electricity bills will increase which prompts many EV drivers to look at ways to maximise their savings.
In response to this demand, and to add incentives for EV drivers to charge at off-peak times, several energy companies have introduced energy tariffs tailored specifically for EV owners.
These tariffs typically have lower unit costs during the night, when demand on the national grid is lower, a renewable energy promise and some offer added benefits for the EV driver.

*NOTE: Costs listed above are intended as a guide only. Figures correct as of August 2018, but subject to change, with tariffs and/or costs able to be altered or withdrawn by each energy supplier. Many of the costs listed above are the lowest cost per day, while peak prices may be considerably higher. Where possible, costs per kWh quoted by the energy provider in marketing material have been used. Where these haven’t been available, costs are calculated on a young family in a medium-sized house, based in south east Wales. Individual quotes could vary from those above, depending on circumstances. Always research personalised quotes carefully before signing up to an energy supply tariff.
The costs per kWh from Green Energy and Octopus Energy above stand out as being much cheaper than the others listed. However, since these are the off-peak costs, charges for energy usage at peak times or other periods may work out more expensive than other tariffs available.
All of the above EV-tailored tariffs above include a renewable energy promise, with the supplier matching energy used by the customer with electricity from renewable sources. It means that those who take up one of those tariffs are not only reducing their costs, but also their ‘well-to-wheel’ emissions.
Electric vehicles may be much greener than ICE models, but there are still emissions to be taken into account from the UK’s average electricity mix. With a renewable-based tariff, EV drivers can rest easy in knowing that powering their electric vehicle is not adding to air pollution.
There are other benefits potentially available too. Some energy companies have provision to off-set mileage for a certain amount of time, plant a tree in honour of your switch over, or offer special deals on home charge points.
There are a number of other energy tariffs available, with some that may suit EV owners but without being labelled as such. The ‘Big 6’, along with other energy providers, will be able to offer other costs, but those listed above as pitched as being particularly suitable for EV drivers.
As always, it’s worth looking around for the best deal for you personally. By switching to a low off-peak tariff – suited to EV charging – those households with higher electricity consumption during the day may end up worse off overall, since peak costs per unit typically increase a little on such plans.
The use of a Smart Meter could be one way to improve electricity use when charging an EV without any additional cost or change over of tariff. These are free to be installed by your energy provider (provided conditions are met) and help home owners keep track of their costs, energy usage etc.
