As fuel prices continue to fluctuate and electric vehicle (EV) adoption grows across the UK, one question keeps coming up: Is it actually cheaper to drive electric in 2026, or does petrol still come out on top?
It depends on your vehicle use. If you drive high annual mileage, have access to home charging (especially off-peak), or can utilise salary sacrifice schemes, electric cars often come out ahead when adding up the full ownership costs, including fuel, tax, and maintenance.
For drivers with lower mileage or no access to home charging, petrol may still be more economical.
This guide walks you through a step-by-step comparison of electric and petrol costs across the UK. Looking at the differences in purchase price, leasing, running expenses, and long-term value helps you make an informed choice about which is cheaper right now.
Quick answer: Is electric or petrol cheaper in 2026?
Cost factor | Electric vehicles | Petrol cars |
|---|---|---|
Upfront cost | Higher (but falling) | Lower |
Monthly lease | Slightly higher | Lower |
Running costs | Much lower | Higher |
Maintenance | Lower | Higher |
Tax (UK) | Lower | Higher |
Long‑term cost | Often cheaper | Often more expensive |
Verdict: Petrol cars usually have lower purchase prices, but electric cars can cost less in total, particularly for drivers who cover regular distances or charge their cars at home.
Purchase and leasing costs: Petrol is still cheaper upfront
Electric cars still cost more than petrol in most segments, though the gap has narrowed in recent years.
The average EV price in the UK is around £43,896. For comparison, the average price of a petrol car is approximately £28,000, highlighting the current gap in upfront costs between the two types of vehicles.
Entry‑level models start from around £15,000.
Petrol cars benefit from decades of manufacturing scale, keeping list prices lower.
EVs cost more upfront largely because battery production relies on expensive raw materials and newer supply chains. Many electric models also sit in premium segments, which inflates average prices.
That said, battery costs are falling, more affordable EVs are entering the market, and the used EV market is expanding rapidly. For buyers considering used cars, it's worth noting that used petrol cars typically have lower upfront prices, but the gap is closing as more used EVs enter the market and their values become more competitive.
In many cases, used electric cars now offer long-term running costs similar to, or even better than, those of used petrol models, making them an appealing option for budget-conscious drivers.
Typical UK purchase prices (2026)
Vehicle segment | Petrol model (from) | Electric model (from) |
|---|---|---|
Small hatchback | VW Polo, Ford Fiesta (£18k–£20k) | MG4 EV, Peugeot e‑208 (£23k–£26k) |
Family SUV | Nissan Qashqai (£28k–£32k) | Tesla Model Y (£35k–£40k) |
Executive saloon | BMW 3 Series (£38k–£42k) | Tesla Model 3 (£45k–£50k) |
Leasing Costs: Where the difference really shows
Because most UK drivers lease or finance their car, the monthly cost is often more relevant than the list price.
On a typical private lease, electric cars usually cost more per month than petrol models, though the gap is often smaller than expected and doesn’t account for running cost savings.
Petrol wins on private lease price alone.
Electric closes the gap through lower running costs.
How salary sacrifice changes the equation
For many drivers, salary sacrifice makes EVs significantly cheaper.
Through a salary sacrifice scheme:
Payments are taken from gross salary (before tax and National Insurance).
EVs benefit from low Benefit‑in‑Kind (BiK) rates (around 3% in 2025/26).
Packages often include insurance, servicing, tyres and breakdown cover.
This can reduce the effective monthly cost by 20-50%, meaning an EV that looks more expensive on paper can actually be cheaper than a petrol car in real terms.
This is a major reason electric car adoption is accelerating in UK workplaces.
Fuel vs charging costs: Where EVs pull ahead
Here, electric vehicles generally win, and savings add up quickly.
Cost per mile (UK)
Fuel/charging type | Typical cost per mile |
|---|---|
Petrol | 12-18p |
EV (home charging) | 2-7p |
EV (public rapid charging) | 10-20p |
Charging at home, particularly on an off‑peak smart tariff, makes EVs dramatically cheaper to run day‑to‑day. However, it is important to factor in the cost of installing a home charger, which typically ranges from £800 to £1,200 in the UK. There are sometimes government grants available that can reduce this cost, but eligibility and amounts may vary. Even with this initial installation cost, running an EV at home can offer significant long-term savings. Even public rapid charging, while more expensive, is often similar to petrol and is usually used less frequently.
For drivers covering regular mileage, this can mean £100-£150+ in fuel savings alone.
For home charging options, we are partnered with Rightcharge. Alongside access to the UK's largest public EV charging network, Rightcharge's EV charging home reimbursement ensures fair and accurate driver payments. Rightcharge automates employee home EV charging reimbursements by integrating with chargers, vehicles, and energy suppliers, ensuring accurate payments and HMRC-approved invoicing, simplifying all EV charging spend into a single bill for your business. This means you'll no longer have to manually manage driver receipts and expenses, or leave them out of pocket with the Government's Advisory Electricity Rate (AER).
Running costs: Electric vs petrol
Maintenance and servicing
Electric cars have fewer moving parts and require no oil changes. Regenerative braking also reduces brake wear, usually resulting in lower servicing and maintenance costs over time.
Petrol cars, by contrast, require regular oil changes, more complex engine maintenance, and typically higher wear and tear.
Tax and incentives (UK)
This is another area where EVs retain an advantage.
Tax consideration | Electric vehicles | Petrol cars |
|---|---|---|
Road tax (VED) | Changing from April 2025 | Standard rates apply |
Benefit‑in‑Kind | ~3% | Up to 37% |
Clean air zones | Usually exempt | Often charged |
EVs remain significantly more tax‑efficient overall, particularly for company car drivers and urban commuters.
Real‑world monthly cost example
Rather than comparing individual line items in isolation, it’s useful to look at the total monthly cost.
Monthly cost example | Electric car | Petrol car |
|---|---|---|
Lease/payment | £450 | £400 |
Fuel/charging | £40 | £160 |
Maintenance & tax | £30 | £90 |
Total | £520 | £650 |
Result: Although the monthly payment for an electric car may be higher at first glance, the total monthly cost, factoring in fuel, tax, and maintenance, often makes the electric car the less expensive choice overall.
When petrol might still be cheaper
Petrol cars can still make financial sense if you:
Don’t have access to home charging.
Rely heavily on rapid public chargers.
Drive low annual mileage.
Want the lowest possible upfront cost.
When electric cars are cheaper in 2026
Electric cars are usually the better financial option if you:
Drive regular or high mileage.
Can charge at home (especially off‑peak).
Have access to a salary sacrifice scheme.
Want predictable running costs and long‑term savings.
Final verdict: What’s actually cheaper right now?
In 2026, while petrol cars generally have a lower initial price, electric cars increasingly offer better value when all ownership costs are considered over time.
Electric cars are increasingly winning on the total cost of ownership.
For many UK drivers, especially those with home charging or salary sacrifice, access to electric vehicles is now the overall cheaper option.
