12 million drivers are considering buying an electric vehicle in the next two years, saving motorists £8 billion in fuel

  • 12 million drivers are considering swapping their diesel or petrol car for an electric vehicle within the next two years[1]

  • Electric vehicles could save an average driver up to £329 a year compared to the cost of petrol or diesel — a potential £8 billion saving for UK motorists[2] 

  • EV users charging their car at home say it adds £370 a year to their energy bills - but those on default tariffs could save £92 a year by switching to a fixed rate deal[3]

  • Modern electric vehicles (EVs) can go an average of 213 miles on a single charge, with the Renault Twizy costing as little as 1.6p in electricity per mile[4]

  • Charging EVs at home can save £2.35 per 100 miles compared to using a public motorway charging point[5]

  • Uswitch.com offers tips on what to look for in an electric vehicle tariff and what effect charging one will have on your energy bills.

12 million drivers are considering swapping to an electric vehicle in the next two years[1], potentially saving £8 billion in fuel costs[2], reveals new research by Uswitch.com, the comparison and switching service.  

Electric car owners save an average of £329 a year, compared to the cost of running a petrol or diesel vehicle, based on typical annual mileage[2]. 

EVs have become increasingly popular among motorists, and their market share is expected to grow in the coming years as the Government bans sales of new diesel, petrol and hybrid vehicles from 2035. 

Although switching to an EV and charging it at home increases energy bills, it works out cheaper than filling up on petrol or diesel, according to the analysis.

Electric car drivers say charging their vehicle at home adds £30.90 a month, the equivalent of £370 a year, to their energy bills. Meanwhile their petrol and diesel-driving counterparts say they spend £74.86 on fuel a month on average, or £898 a year. When adjusted for average mileage, electric vehicle owners save £27.48 a month compared to fuel, equal to £329 a year[2].

To ensure EV drivers are not paying over the odds to charge their car, owners should ensure they are on one of the cheapest fixed energy deals available on the market[3]. Consumers on Standard Variable Tariffs who are charging their electric cars at home could save up to £7.69 a month — £92 a year — by ensuring they are on the best energy deal.

Charging at home is usually cheapest for electric vehicle owners. Motorway charging points are capable of delivering enough electricity to drive 100 miles in just half an hour — but it will cost about £6.50, compared to £4.15 on average with a 7KW wall charger at home[5]. 

Some 4.3 million drivers (11%) say they will buy an electric vehicle in the next two years, and an additional 7.6 million motorists (19%) are considering purchasing one in that time[1]. 

Registrations of new EVs also reached a market share of 4.6% in March — the highest proportion of sales recorded in the UK for battery powered cars[6]. 

Cost per mile Uswitch.com analysed the prices of new EVs and their cost per mile to calculate which cars provide the biggest cost savings over an average eight-year warranty period. The compact Renault Twizy came out on top, costing only 1.61 pence per mile, and a total of £11,745 including the purchase price after eight years[4].

Tesla is one of the best-known EV brands and its cars boast some of the best ranges, but they are among the most expensive vehicles to own. 

Uswitch.com is offering EV owners tips on what to look for in a tariff and what effect charging one will have on your monthly costs in its guide to electric cars and what impact it will have on my energy bill.

Sarah Broomfield, energy expert at Uswitch.com, comments: “Electric vehicles are becoming increasingly popular, and 12 million drivers could soon be swapping their petrol or diesel car for a more environmentally friendly one.

“The good news for these drivers is that EVs come with an additional financial benefit too — they cost far less to fuel than a petrol or diesel car. 

“However, charging costs can vary depending on your energy tariff. If you are still on your supplier’s Standard Variable Tariff, charging your car could cost an additional £7.69 a month unless you switch to a more competitive fixed-term deal.”

Notes to editors:
Opinium surveyed a sample of 2,001 UK adults from the 14th to 18th August 2020. Results were weighted to reflect a nationally representative criteria.
1. Respondents were asked ‘Thinking about your future car purchases, would you consider buying an electric vehicle in the next 2 years?’ 11% said ‘Yes, I will be buying one in the next 2 years’ 19% said ‘Yes, I am considering buying one in the next 2 years’. Respondents were asked ‘What type of car do you drive?’ 24% said ‘I don’t drive a car’. 52.4 million adults in the UK. 76% of 52.4 = 39.8 million drivers. 30.7% = 12.2 million drivers considering buying an EV.
2. Average fuel consumption for petrol and diesel cars are 50.5mpg and 57.9mpg, according to the Department for Transport. Average fuel petrol and diesel prices are 114.66 pence per litre and 118.34 respectively, according to RAC Fuel Watch. Petrol: 50.5mpg x 0.22 litres per gallon = 11.11mpl. 114.66p per litre / 11.11mpl = 10.32 pence per mile. Diesel: 57.9mpg x 0.22 litres per gallon = 12.738mpl. 118.34p per litre / 12.738mpl = 9.29 pence per mile. (10.32 + 9.29) / 2 = 9.805 pence per mile on average for diesel and petrol. 4.15 pence per mile for EV. 9.805 - 4.15 = 5.655 pence per mile saving. 5.66 x 5,829.3 average mileage for all fuel types = £329.64 a year.
£329.64 saving a year x 12.2 million = £4.02 billion X 2 years = £8.04 billion
3. Average SVT = £1,125 a year. Best priced fixed deal (correct as of 20/08/20 is £810.34 from Avro Energy. £810.34/£1,125 = 72%. 72% of £27.48 = £19.79. £27.48 - £19.79 = £7.69. £7.69 x 12 = £92.28.
4. Uswitch.com compared the battery size and range of EVs on sale in the UK, to calculate the cost per mile. Data collected using manufacturer brochures and official websites. 
6. SMMT new car registrations March 2020.
