Lexus NX 300h running costs

Hybrid company-car drivers get benefits compared to diesels, but otherwise there are few financial incentives over diesel or plug-in alternatives

Insurance group Warranty Service intervals 2019/20 company-car tax cost (20%/40%)
29-30 3yrs / 60,000 miles 1yr / 10,000 miles From £2,244 / £4,488

With prices ranging from around £35,000 to £45,000, the NX 300h looks pretty competitive against traditional non-hybrid rivals like the BMW X3 and Audi Q5, especially when you take into account its high equipment level. Plug-in hybrid rivals tend to be more expensive again, so the NX 300h remains an attractive option for buyers considering their green options.

Unfortunately, the Lexus hybrid doesn’t qualify for the Plug-In Car Grant when you purchase it and its CO2 figure makes it liable for the London Congestion Charge, too. But the CO2 figure does provide an incentive for company-car drivers, especially if they’re comparing Benefit-in-Kind (BiK) rates with traditional SUVs that may have higher figures and which also face the 3% diesel surcharge. The NX 300h’s 27% compares favourably with 32% for the Volvo XC60 D4 Momentum, for example.

Plug-in hybrids fare much better, of course, with the Volvo XC60 Twin Engine costing company-car drivers just 16% in BiK. Fuel economy may also be a factor when comparing a self-charging hybrid with either diesel or plug-in hybrid rivals. The former are likely to offer cost savings at the pumps if you drive high mileage, whereas the latter may rarely visit the pumps at all if you drive a limited number of miles.

Lexus NX 300h insurance group

As there’s only one engine and a handful of trim levels, it’s not surprising that the Lexus NX falls into a relatively small insurance-group range. Depending on specification, it’s in group 29 to 30, while the Volvo XC60 and Jaguar F-Pace ranges both start at group 31.


The standard Lexus three-year/60,000-mile warranty applies to the NX 300h, but you get five-year cover on the hybrid powertrain components, which includes the battery.


The cost of keeping your service book stamped shouldn’t be too much to bear. Intermediate servicing at 10,000, 30,000 and 50,000 miles costs £245, while full services at 20,000 and 40,000 are both less than £450 according to the official Lexus prices.

Road tax

The NX 300h range straddles the £40,000 luxury surcharge for road tax, so you’ll need to be careful even if adding options to the entry-level model. Go over the limit, and you’ll pay an extra £320 over the regular rate of £135 in years two to six, for a total of £455.


The Lexus NX line-up should retain between 50 to 55% of its value after three years and 36,000 miles, which is a little better than a diesel BMW X3 and most Audi Q5s.
