EV battery replacement cost in the UK: published prices, warranty and repair options
Published · Last updated
The fear of a big battery bill is one of the main reasons people hesitate over a used EV. This guide collects the UK replacement prices we could trace to the company that set them, explains why there are so few, and shows what to check first: the battery warranty, recalls, and whether a repair is possible. It also covers how rarely batteries are actually replaced.
The worry is real: 76% of UK consumers in a 2026 Startline survey said they were concerned about battery repair or replacement costs (Startline Motor Finance, 2026-08-17).
Check the warranty and recalls first
- Battery warranty. Of the 49 battery-warranty terms we track across 36 models, 41 run for 8 years or more and 36 pay out if capacity falls below 70% (mileage caps and conditions apply). Work out the time and mileage left for a specific car with the battery warranty checker, and confirm it with the manufacturer using the VIN.
- Recalls. Battery faults covered by a recall are fixed by the manufacturer. Hyundai, for example, replaced batteries in 75,680 Kona Electric cars worldwide over a fire risk (BBC News, 2021-02-24). Check any car on GOV.UK's recall checker (GOV.UK); see our Kona Electric recall guide.
- Warranty conditions. A capacity warranty usually means the maker repairs the battery back to a set level, not that you get a brand-new pack. Nissan's 2019 Customer Promise terms, for example, say it will repair or replace battery components to bring capacity back to 9 of 12 bars (Nissan Motor).
Published UK prices we could verify
Most makers and garages don't publish a battery price; they quote for the specific car. These are the published UK examples we could trace to the company that set them. They are almost all for the Nissan Leaf, the oldest common used EV.
| What | Car | Published price | Notes | Source (date) |
|---|---|---|---|---|
| New battery from Nissan UK | Nissan Leaf / e-NV200, 24 kWh | £4,920, after £1,000 for the old battery | Autocar says the price included VAT; Zapmap reported it as plus VAT, so the reports disagree. A 2014 price for the 24 kWh pack only; we found no published Nissan UK price for 30, 40 or 62 kWh packs. | Autocar (2014-12-08), Zapmap (2014-12-09) |
| Bigger reclaimed battery fitted by a specialist | Nissan Leaf 24 or 30 kWh, upgraded to 40 kWh | £5,995 inc. VAT | Reclaimed (not refurbished) battery from a Nissan about 1–2 years old; 3-month battery and 12-month labour warranty; car needed for two days. | Cleevely Electric Vehicles (checked 2026-10-27) |
| Same, to 62 kWh | Nissan Leaf 24 or 30 kWh, upgraded to 62 kWh | £7,995 inc. VAT | As above. | Cleevely Electric Vehicles (checked 2026-10-27) |
| All modules replaced by a specialist | Nissan Leaf / e-NV200, 40 kWh | £5,950 + VAT (£4,800 modules + £1,150 labour) | 3–4 working days. With VAT at the standard 20% that would be £7,140 (our calculation). | Kinghorn Electric Vehicles (checked 2026-10-27) |
Prices as published by each company on the date shown; they can change and may not include diagnosis, transport or other work. Nissan said in 2014 that it had replaced three batteries out of 30,000 Leafs sold in Europe (Autocar).
For comparison (US, not UK): Recurrent put typical out-of-warranty replacement costs at $5,000–$16,000 depending on pack size and maker (Recurrent, 2024-12-03). US prices don't convert directly to UK quotes.
Not the same thing: battery buy-outs on a Renault Zoe. Some older Zoes have a leased (hired) battery. Buying it out is not a replacement, but it is a cost to know about: individual quotes ranged from £1,586 to £2,840.40 in 2024 (The Guardian, Financial Ombudsman Service). See the Zoe battery lease guide.
Repair, modules or a whole pack?
A battery pack is made of modules, which are made of cells. Depending on the car and the fault, a specialist may replace a single module, all the modules, or the whole pack. Kinghorn Electric Vehicles says it used to replace only the swollen modules in 40 kWh Leaf packs but found the mix of old and new modules caused balancing and performance problems, so it now recommends replacing all of them (Kinghorn Electric Vehicles).
Cell balance matters too: in Generational's UK tests about 1 in 200 cars had a spread of more than 100 mV between cells, which it calls a potential underlying fault (Generational). See how to read cell balance in our certificate guide.
Questions to ask before you agree to work:
- What exactly is the fault, and how was it diagnosed? Can I see the report?
- Will you replace one module, all modules or the whole pack? New, refurbished or reclaimed parts?
- What warranty comes with the battery and with the labour, and does any manufacturer warranty still apply afterwards?
- Is the price fixed and does it include VAT, diagnosis, coolant and any software or set-up?
- Is the work done by technicians qualified for high-voltage systems?
What this means if you're buying a used EV
- Get an independent battery test and compare the result with data for the model: model pages, the battery health estimator, all models compared.
- Check how much battery warranty is left with the warranty checker; a car well inside it carries much less replacement risk for you.
- Ask the seller about the battery history, repairs and recalls with our printable list of questions.
- If a car is out of warranty with a weak battery, get a written repair quote before you agree a price, and use it in the negotiation.

We are not paid by these test providers. How we make money.
Model averages can't tell you about the car in front of you. An independent battery test (typically a short OBD plug-in test, some remote) gives an SoH figure and often a certificate you can use when negotiating.
- AVILOO – Independent OBD-based battery test (FLASH / Premium) with certificate; available via partners in the UK and EU.
- Generational – UK OBD plug-in test with certificate (SoH, range, remaining warranty, cell balance); sold through dealers and independent mobile testers.
- Moba – Postal OBD kit: you run the test yourself and post the box back for a digital battery certificate (Europe – check vehicle support and delivery country).

FAQ
How much does it cost to replace an EV battery in the UK?
Few UK prices are published, and most garages quote car by car. The published examples we found are for the Nissan Leaf: £4,920 for a new 24 kWh battery from Nissan UK in 2014 (after a £1,000 trade-in for the old one), and current specialist prices of £5,995 to £7,995 including VAT to fit a reclaimed 40 or 62 kWh battery, or £5,950 plus VAT to replace every module in a 40 kWh pack. Get a written quote for the specific car that includes fitting and VAT.
Is EV battery replacement covered by warranty?
Usually, if the car is still inside the battery warranty and the capacity has fallen below the threshold. Of the 49 battery-warranty terms we track across 36 models, 36 pay out below 70% capacity, and most run for 8 years with a mileage cap. Faults covered by a recall, such as the Hyundai Kona Electric battery recall, are fixed free by the manufacturer.
How often do EV batteries need replacing?
Rarely. Recurrent, which tracks more than 30,000 connected EVs in the US, found that outside two big recalls under 4% of batteries had been replaced, including cars over ten years old. The rate was around 8.5% for first-generation EVs and 0.3% for EVs from 2022 onwards.
Can an EV battery be repaired instead of replaced?
Sometimes. A pack is made of modules, and some specialists replace modules rather than the whole battery. One UK Leaf specialist says that replacing only the damaged modules caused balancing and performance problems, so it now replaces all of them. Ask what exactly will be replaced, what warranty comes with it, and who does the work.
