Buying an electric car and expecting it to be cheaper to run all round? The insurance bill often comes as a surprise. Electric vehicles have generally cost more to insure than equivalent petrol or diesel models, though the gap is closing. At its 2024 peak, EV cover ran roughly 25% above comparable combustion cars; by 2026 that had narrowed to around 10-15% as insurers gathered data and repairs got easier, according to industry coverage. For some models and drivers, an EV now costs the same or less to insure than a petrol equivalent.
Why premiums are higher
A premium, the price you pay for cover, is set by how likely a claim is and how much it costs to settle. With EVs, the issue is not that drivers crash more; it is the cost and complexity of repairs.
The battery is the heart of the problem. An EV's high-voltage battery pack can be a large share of the car's value, and replacing one is expensive. Because insurers still lack decades of repair history for these packs, even modest underbody damage, the kind of knock a petrol car would shrug off, can trigger costly inspections or, in the worst case, a "write-off", where the insurer judges the car a total loss because repairing it costs more than it is worth.
Beyond the battery, EV claims tend to run higher and slower. Research by Thatcham, the UK automotive-safety body, has found EV claims are meaningfully costlier than petrol equivalents and take longer to repair, as Forbes reported. Specialist parts and sensors, fewer aftermarket alternatives, and a shortage of technicians certified to work safely on high-voltage systems all push up the labor and time, and therefore the price, of putting an EV back on the road.
What is bringing the cost down
The encouraging part is that these are solvable, temporary problems, and the system is adapting. Thatcham has pushed for design and repair changes, including making battery packs easier to assess and repair rather than replace, and better access to diagnostic data, that would cut unnecessary write-offs, Forbes reported. Regulators in Europe and North America have moved toward requiring carmakers to share vehicle diagnostic information with independent repairers, so a simple fix no longer means waiting on the manufacturer.
More technicians are gaining high-voltage certification, and new tools let repairers judge whether a damaged battery genuinely needs replacing or can be safely repaired. As that repair ecosystem matures and insurers accumulate claims data, the extra risk they price in shrinks, which is why the premium gap has been falling.
How to factor it into a purchase
The practical lesson is to look at the whole cost, not the sticker price. "Total cost of ownership" means the purchase price plus running costs, fuel or charging, maintenance, insurance and depreciation, over the years you will own the car. EVs typically save on fuel and routine maintenance, but a higher insurance bill can offset part of that, so it belongs in the calculation.
Two simple steps help. First, get insurance quotes for the specific models you are considering before you buy; premiums vary widely, and a mainstream EV can be far cheaper to cover than a heavy, high-performance one. Second, check what a policy actually covers, including whether repairs can be done at independent shops rather than only manufacturer dealers, as that flexibility grows more valuable as the repair network expands. The EV insurance penalty is real, but it is neither fixed nor permanent. This article is educational and general in nature, not individual financial or insurance advice.
