The Mercedes GLC plug-in hybrid is aimed at company-car users, because the lower tax rates for cars that can drive on electric power alone mean they’re a lot cheaper to run than normal petrol or diesel SUVs. It doesn’t matter if you choose the petrol or diesel plug-in GLC – both are very cheap to tax (relatively speaking) for company users.

Business users will pay from £1,348 or £2,696 respectively depending on whether they're 20% or and 40% earners. Private buyers will need to use electric power in their favour if they want to save money, as the plug-ins are more expensive to buy than regular combustion-engined models, so you have to claw back the cash in fuel savings.

Mercedes GLC hybrid SUV insurance group

Insurance groups range from 43 for the petrol GLC 300 e petrol up to 45 for the higher-spec GLC 300 de. The insurance ratings for the purely petrol and diesel variants are lower, but the plug-ins are fast, powerful and have a complex electrical powertrain that potentially costs more to repair after an accident, hence the higher ratings.


All Mercedes models are covered by a three-year/unlimited-mileage warranty. Plus, the battery has its own cover that protects buyers from having to fork out to replace it if it goes wrong.


Mercedes sells service plans through its ServiceCare plan, giving buyers the option to pay for two, three or four services over one, two, three or four years. It’s a flexible setup, so the costs aren’t set in stone, but are comparable to those from BMW or Audi, for example.

Road tax

As the GLC hybrids are ‘alternative-fuel vehicles’ they get £10 off a year when it comes to Vehicle Excise Duty (VED), otherwise known as road tax. This means they’ll cost £145 a year to keep on the road, plus a surcharge of £335 in years two to six due to their high list price, making the yearly cost in that period is £480.
