Used electric car finance: a buyer's guide for 2026

Used EVs are more affordable than ever — but finance works differently

Used electric car prices have fallen by around 10% year-on-year, making 2026 one of the best times to get into an EV without paying new-car money. A used Nissan Leaf, Renault Zoe or Volkswagen ID.3 that cost £25,000 two years ago might now be sitting on forecourts — including ours — for considerably less.

But here's what most dealers won't tell you: financing a used electric car involves a few considerations that don't apply to petrol or diesel. Battery degradation, residual values, government grants (or lack of them) and running cost savings all affect how you should structure your deal. This guide walks through each one plainly, so you can make the decision that actually suits you.

Do government grants apply to used EVs?

This is one of the most Googled questions about used EV buying — and the answer is straightforward: no, the UK government's plug-in car grant does not apply to used electric vehicles. The grant (currently available to new EVs via dealers) only applies to brand-new vehicles and is claimed by the dealer at point of sale.

However, this doesn't mean there's no financial support available. Several local councils and energy suppliers offer grants for home charging installation (the OZEV Electric Vehicle Homecharge Scheme covers up to £350 toward a home charger), and some workplace charging schemes are still available to employees. The financial case for a used EV doesn't depend on grants — it depends on the running cost gap between electric and petrol, which is substantial.

How battery degradation affects PCP residual values

This is the detail most PCP customers don't think about until it's too late. In a standard PCP deal, the finance provider sets a Guaranteed Minimum Future Value (GMFV) — the predicted value of the car at the end of the term. That GMFV is what determines your balloon payment and, crucially, your monthly payments.

For used EVs, battery health is the biggest variable. A battery that has degraded significantly from its original capacity will drag down the car's residual value, which means two things: the finance provider may set a lower GMFV (increasing your monthly payments), or they may set an optimistic GMFV that doesn't account for further degradation — leaving you with a car worth less than the balloon at the end of the term.

The smart move before signing any PCP on a used EV is to request a battery health report. Most modern EVs (particularly from 2019 onwards) can produce a diagnostic showing current battery capacity as a percentage of original. Anything above 80% is generally considered healthy. Below that, factor in potential range reduction and weaker residuals when assessing the deal.

PCP vs HP for used electric cars: which is better?

This is genuinely different for EVs than it is for petrol cars, and the answer depends on one key question: how confident are you in the battery's long-term health?

PCP suits you if: you want lower monthly payments, you're planning to change cars in 3–4 years, and the EV has a strong, documented battery health. The GMFV protects you if the car depreciates faster than expected — you can simply hand it back. For EVs from established manufacturers with proven battery longevity (Tesla Model 3, Hyundai Kona Electric, Kia e-Niro), PCP works well.

HP suits you if: you want to own the car outright, you're planning to keep it long-term, or you're uncertain about how residual values will move. HP means you own the car at the end — no balloon, no surprise about whether the car is worth more or less than a predicted figure. For buyers switching to EV for the first time and planning to run it for 5+ years, HP often makes more financial sense.

One practical advantage of HP on a used EV: you can't be caught out by a GMFV that didn't account for battery degradation. You pay down the full value of the car in equal instalments and own it at the end, regardless of what the used EV market does.

How running cost savings change the monthly maths

Here's the calculation most finance comparisons skip. A used EV financed at, say, £250/month looks more expensive on paper than a used petrol equivalent at £180/month. But the monthly fuel cost gap is significant — and it materially changes the true cost of ownership.

Charging a typical used EV (say, a 40kWh Nissan Leaf) at home on a standard tariff costs roughly £6–£8 for a full charge, giving around 150 miles of range. The equivalent petrol journey in a comparable hatchback costs approximately £20–£22 in fuel. For a driver covering 1,000 miles per month, that's a saving of roughly £100–£120 per month in fuel costs alone — before accounting for lower servicing costs (no oil changes, fewer brake replacements due to regenerative braking, no exhaust or cambelt to worry about).

When you factor in those running cost savings against the monthly finance payment, the gap between EV and petrol finance narrows considerably — and for many drivers, disappears entirely or tips in the EV's favour.

What to look for in a used EV deal in 2026

Whether you go PCP or HP, here's what to check before signing anything on a used electric car:

Battery health certificate. Ask the dealer for a battery diagnostic printout. At Carsa, every used EV goes through a comprehensive vehicle preparation process — battery health is part of that check.

Remaining manufacturer warranty. Many EVs come with an 8-year/100,000-mile battery warranty from the manufacturer. Check where your target car sits within that window. A 2019 Nissan Leaf, for example, has a battery warranty running to 2027.

Charging compatibility. Older EVs (pre-2020) may only support slower AC charging rather than DC rapid charging. For most urban or suburban drivers this is fine — but worth knowing before you buy.

Home charging setup. If you don't already have a home charger, factor the installation cost (typically £300–£500 after the OZEV grant) into your budget. Public charging-only running is significantly more expensive per mile.

Finance rate and total cost of borrowing. At Carsa, used EV finance starts from 10.9% APR. Always compare the total amount payable — not just the monthly figure — to understand the full cost of the deal.
