The Hyundai Ioniq Hybrid range starts at just under £23,000 for the basic Hybrid and tops out at just under £32,000 for the Plug-In in Premium SE trim. The Plug-In itself starts at £29,950 in Premium trim. That's the spec we recommend, unless you really want the heated seats, privacy glass and other accoutrements that Premium SE adds.

Company-car drivers enjoy a low Benefit-in-Kind rate, and whichever trim level you go for, the Ioniq Plug-In will return up to 257mpg officially and emits 26g/km of CO2, which means it’s exempt from the London Congestion Charge until October 2021.

Hyundai Ioniq Plug-In insurance group

Since the late 2019 update, both versions of the Ioniq Plug-In Hybrid fall into insurance group 12. That’s on par with the Toyota Prius Plug-In, but quite a bit lower than pure-electric cars such as the 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 for five years, with no mileage limit. There’s also a 12-year anti-perforation warranty, plus a separate 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 can discuss these with you.

Road tax

Annual road tax is only free on cars with no CO2 emissions these days. However, Ioniq Plug-In drivers will only pay £145 a year from the second to sixth year of ownership – £10 less than any non-hybrid car.
