Electric vs Petrol ownership costs
Electric vehicles (EV’s for short) are the coming thing in motor transport; some of the major
manufactures such as Nissan with their Leaf model have made serious inroads into the private vehicle sector and in the next two years all the big manufacturers are planning to release a range of fully electric vehicles.
In this article we are going to take a look at the average costs associated with owning an EV priced against the average amount of money customers pay for a new car in the UK (£33,559) using PCP (Personal Contract Purchase) over three years, which is currently the most popular method of financing a new car in the UK.
To start with, it is worth stating that electric cars are more expensive like for like than equivalent petrol or diesel model. As an example, the base model Nissan Leaf starts at £27,995 whilst an equivalently specified Nissan Qashquai starts at £19,995. Volkswagen completed a survey of the public in 2018 and one of the public’s concerns was the initial outlay required to purchase an EV. However, as more manufacturers get on board with manufacturing EV’s the cost will be driven down to become more in-line with more conventional vehicles.
To make things fair we are going to take two vehicles one electric and one petrol, priced the same on a 3 year PCP deal covering 10,000 miles annually. It’s important to note that at the end of the three year period, the vehicle will be worth a pre-agreed amount that takes into consideration the value of the car at the time you started the agreement and the value at the end of the agreement. You normally have two choices at the end of the agreement, which is to either pay the final payment or continue with a lease on a new vehicle. Now different vehicles will depreciate a different amount over their lease period, but to keep things simple we are going to assume that they have depreciated the same amount, so the final payment is the same
The initial value of the car is £29,000 and we are going to put a deposit of 10% down, the dealer is going to make a contribution of £1000 towards the deposit and our final payment is going to be £19,000. There is interest applied to the amount borrowed during the lease period, on average this is 7%. In total this leaves us with £6100 to be financed over the lease period. This would leave us with monthly repayments of £299.
So far our cars are both costing the same each month. However, the petrol car is of a higher spec, it has a better interior trim level, sporty alloys with low profile tyres, parking assist and a heads up display – the EV doesn’t have any of this as I’m paying for the technology that’s involved in making the EV a viable driving alternative to the petrol.
Based on just the figure above, when looking at what you get for your money, the petrol car is so far coming out on top. The next thing we are going to look at is running costs, starting with tax. Now tax varies depending on the CO2 emissions of the particular vehicle. My petrol car sits in the middle of these bands. This means for the first year I pay a fee of £165 and every year after that I pay £140. This means my total over three years is £445.
My EV however produces no CO2 emissions; this means that my tax is £0, which is an immediate saving.
Cost of fuel is the next thing most people think of. My petrol car consumes fuel at an average of 38 mpg, which is about normal for a modern mid-sized petrol engine covering the 30,000 miles over the three years in my lease; this is going to cost me approximately 12p per mile or £3600 total over the three years.
My electric car has an average range of 150 miles on a full charge. To fully charge my car at home cost approximately £6.60, or 3.5p per mile. Over the three years of the lease and covering the maximum 30,000 miles this is going to cost a total of £1050.
All in all I have saved £2550 in fuel by using an EV.
Insurance is the next consideration. Here is where EV’s lose out to more conventional vehicles. Because the technology is new and the numbers are still small compared to petrol and diesel cars, insurers do not have a huge bank of information regarding repair costs etc to draw upon, as a result EV Insurance premiums can sit around 25% more expensive. In this instance my petrol car has cost me £475 per year to insure, giving me an overall cost of £1425 for the three years. My EV is 25% more expensive so costs me £593 per year, totalling £2375 over the 3 years.
Servicing costs also need considering. My petrol car cost me an average of £550 in servicing costs per year over the three year period for a total of £1650. My EV costs £300 per year over the three year period for a total of £900. This cost saving is down to a mixture of parts and labour saving with the EV. The EV doesn’t use the same amount of consumables as the petrol car such as oil and filters.
There is one additional cost to owning an EV that is worth considering however and that is a dedicated charging system for your home. The advantage these have over using a conventional domestic socket circuit and a charging lead is the speed with which they can charge the vehicle. Using a normal circuit it can take up to 13 hours to charge a Nissan Leaf for example, from empty to fully charged. A dedicated charger can reduce this time down to as little as three hours. The cost of installing these can range from as little as £300 for a basic charger installed into a property that requires no remedial work to getting on into the thousands of pounds if your property is in need of an electrical upgrade before an installation can be completed. The government offers an incentive scheme called OLEV for which you may be eligible. If you are eligible for this scheme and use an OLEV registered installer you can claim 75% up to £500 back off of the installation cost.
So, which works out cheaper? Petrol car total cost per mile – 59p per mile EV total cost per mile – 50p per mile
At first glance 9p per mile doesn’t look like much of a saving, however after over 30,000 miles and three years that’s a total saving of £2700.
