The analysis by Warranty Solutions Group took in a sample of 1,000 real-world repair claims paid by the company on EV warranties issued between January and December 2025. The resulting data highlights significant differences in both fault rates and repair costs across the UK's most popular electric models – offering valuable insights for drivers and dealers alike.
The Nissan LEAF topped the reliability rankings with an impressively low claim rate of just 1.52 per cent, making it a reassuring choice for EV buyers seeking peace of mind.
James Taylor, managing director of Nissan GB, said: "This survey uses feedback from real-world customers about the reliability of their cars, and it shows consistently strong performance from the Nissan LEAF.
"For customers new to this technology and perhaps considering an electric vehicle purchase for the first time, knowing it is going to be reliable is very reassuring. We know our customers love LEAF, so it's great to see this reflected in this reliability survey too."
The ground-breaking Nissan LEAF was first launched in the UK in 2011, with UK production starting in Sunderland in 2013. The second-generation model, featuring more technology and increased range, arrived in 2018. This means there's plenty of choice of used models for customers, making it an accessible route into EV ownership.
Meanwhile, the all-new model – feauring a range of up 386 miles on a single charge – arrives in Nissan showrooms across the UK imminently. Proudly built in Britain, the new car also qualifies for the full Electric Car Grant discount of £3,750.
Martin Binnee, Operations Director of Warranty Solutions Group comments: "The LEAF's long-established electric drivetrain, straightforward engineering and proven track record for durability have all contributed to its standout reliability, continuing to translate into dependable ownership and fewer faults."
Warranty Solutions Group (WSG) is the UK's fastest-growing warranty and aftersales specialist, providing bespoke warranty, insurance and data solutions for dealer groups, independent dealers and OEMs.
Martin added: "While some EVs are proving extremely reliable, when faults do occur the cost of repair can be significant - particularly for premium models and vehicles with advanced electrical and thermal systems."
"For consumers, this means looking beyond fuel savings and factoring repair severity into the total cost of ownership. For dealers and warranty providers, it reinforces why EV-specific warranty cover is no longer optional, but essential to protect customers and maintain confidence as electric adoption continues to grow."
