Toyota Prius Plug-In running costs

The electric element of Toyota Prius Plug-In helps keep petrol use to a minimum and means it’ll be super-cheap to run

The Prius Plug-In is exempt from the London Congestion Charge, so if you travel to and from the capital for business or pleasure during the week, you’ll save £11.50 per day.

If you’re a business user, then the breaks are even bigger. Emitting just 28g/km CO2 puts the Prius Plug-In in the lowest BiK company-car tax bracket, at 13%.

It means a higher-rate taxpayer will have to stump up £1,645 to run a Business Edition Plus model (our pick of the range) over a year, but compare this to a efficient family hatchback such as the 1.0-litre turbocharged petrol Vauxhall Astra in a similarly equipped SRi Nav tirm and you’ll save around £350 per year, which could pay for your insurance, for example.

Toyota Prius Plug-In insurance group

On that subject, the Business Edition Plus Prius falls into insurance group 21, while the higher-spec Excel model sits a few groups higher in group 23.

What you’ll pay in insurance premiums will depend on your circumstances, however – factors like where you live, whether you have points on your licence and how much driving experience you have. However, to give an indication of how much you should expect to pay, our sample middle-aged driver with three points on their licence was quoted around £692 per year fully comprehensive.

Warranty

As we’ve mentioned above, Toyota’s five-year/100,000-mile warranty package extends to the Prius Plug-In, so there’s plenty of peace of mind for buyers.

Even used examples of this car will have much more than half the balance of coverage given the Prius hit the market in 2016.

Servicing

With 206 dealers nationwide it’ll be easy to get your Prius serviced – and we’d recommend you go to a main dealer as being serviced by an official Toyota franchise means you’ll keep the extensive warranty cover on the hybrid system components and the battery pack.

Service intervals are every one year or 10,000 miles and alternate between interval and major services. Expect to pay around £169 for the former and £219 for the latter.

Road tax

The Prius Plug-In is an affordable hybrid, so even a top-spec car fully loaded with options will cost a lot less than £40,000. This means you pay the standard rate of road tax for an alternatively fuelled vehicle from the second year of its life onwards, at £130 per year. Given the Toyota’s ultra-low CO2 emissions, you’ll get the first year VED free.

Depreciation

Our spec of choice, Business Edition Plus, will depreciate the least of all the trim levels in the range, according to our experts, but even then the predicted residual values aren’t great.

The Prius is expected to hold on to 43.0% of its price from new, so after three years or 36,000 miles, whichever comes sooner, the car will be worth £13,626 based on these figures. This means it’ll shed £18,069 over this period.
