Hyundai Ioniq Plug-In running costs

The Hyundai Ioniq Plug-In is cheaper than a Toyota Prius Plug-In, but isn’t quite as economical

Insurance group Warranty Service intervals 2019/20 company-car tax cost (20%/40%)
11-12 5 yrs / unlimited miles 12 mths / 10,000 miles From £906.88 / £1,813.76

The Hyundai Ioniq range starts at just under £22,000 for the Hybrid and tops out at just over £30,000 for the Plug-In in Premium SE trim. The Plug-In itself starts at £28,395 for Premium trim. That's the spec we recommend, unless you really want the heated rear seats and front parking sensors that Premium SE brings on top of all of the goodies you get already.

Company-car drivers enjoy a low Benefit-in-Kind rate, and whichever trim level you go for, the Ioniq Plug-In will return 248mpg officially and emits 26g/km of CO2, which means it’s exempt from the London Congestion Charge.

Hyundai Ioniq Plug-In insurance group

The Premium falls into insurance group 10, while Premium SE is in group 12. That’s on par with the Toyota Prius Plug-In, but is much cheaper than a Nissan Leaf, which is in group 21.

As such, insurance premiums should be good value for most drivers. Hyundai offers its own insurance policies, which come with a range of benefits, but you can use your own provider if you prefer. As with any insurance policy, you should shop around for the best deal.


The Hyundai Ioniq’s warranty is comprehensive. As standard, the car is covered by a five-year/unlimited-mile warranty. There’s also a 12-year anti-perforation warranty, plus a lithium-ion battery warranty, which protects against capacity loss for eight years or 125,000 miles.


Service intervals are determined by the Ioniq’s on-board computer, but if you cover an average of 12,000 miles a year, reckon on paying a visit to your local dealer around every 18,000 miles. Hyundai offers a range of service plans to suit your lifestyle – your dealer will discuss these with you when you buy the car.

Road tax

Annual road tax is only free on cars with no CO2 emissions these days. However, Ioniq Plug-In owners pay no road tax for the first year and just £135 in subsequent years.


As with many plug-in hybrid cars, depreciation – the value a car loses over time – is a case of who to believe. One well respected price guide puts the Electric model’s value retained over the first three years and 36,000 miles at around 32%. Expect the Plug-In's figure to be slightly higher, at around 35%.
