Understanding Total Monthly Car Finance & Purchase Costs Doesn't Have To Be Hard

Beyond the monthly payments, the real cost of a new car often lies hidden in the fine print of finance deals. Our platform is designed to demystify Hire Purchase (HP) and Personal Contract Purchase (PCP) options, allowing you to make a truly informed decision about your car purchase.

Electric Car Finance: What You Need to Know Before Buying an EV

Electric vehicles are becoming an increasingly popular choice for UK buyers, and financing an EV comes with its own set of considerations. From higher purchase prices to government incentives, here is what you need to know before signing a finance agreement on an electric car.

Electric vehicles are becoming an increasingly popular choice for UK buyers, and financing an EV comes with its own set of considerations. From higher purchase prices to government incentives, here is what you need to know before signing a finance agreement on an electric car.

Higher Purchase Price, Lower Running Costs

The most significant difference when financing an EV is the higher upfront cost. Electric cars typically command a premium over equivalent petrol or diesel models, which means higher monthly finance payments. However, this is offset over time by significantly lower running costs — electricity is cheaper per mile than petrol or diesel, and EVs have fewer moving parts, leading to lower servicing costs.

When comparing EV finance to traditional cars, always factor in the full cost of ownership, not just the monthly payment.

Salary Sacrifice Schemes

If you are employed, your company may offer an Electric Vehicle Salary Sacrifice scheme. Under this arrangement, you pay for an EV lease directly from your gross salary before tax and National Insurance are calculated, potentially saving between 30–50% on the cost of a new electric car compared to a personal lease. Check with your employer's HR or benefits team to see if this is available.

Grant Schemes

While the full Plug-in Car Grant that previously reduced the purchase price of new EVs has ended for cars, there are still grants available for electric motorcycles, small vans, taxis, and charge points (including the OZEV home charger grant of up to £350). Check the latest position on gov.uk as these schemes are regularly updated.

Battery Depreciation and Residual Values

Battery health and technology advancement are the primary drivers of EV depreciation. Older EVs with shorter ranges have historically depreciated quickly. However, as EV technology matures and the second-hand market grows, residual values for mainstream EVs are stabilising.

If you are considering a PCP deal on an EV, pay close attention to the Guaranteed Minimum Future Value (GMFV) set by the manufacturer — a higher GMFV means lower monthly payments.

Charging Infrastructure Costs

If you do not have off-street parking, home charging may not be possible. Relying entirely on public rapid chargers is more expensive per kWh than home charging and should be factored into your running cost calculations.

For home charging, budget £500–1,000 for a quality 7kW wallbox charger (after any grant).

Is Leasing the Best Option for an EV?

Many EV buyers opt for leasing (PCH) rather than purchasing outright. This makes particular sense for EVs because:

  • Technology advances rapidly, so cycling to a newer model every two to three years keeps you ahead of the curve.
  • You are not exposed to residual value risk if battery technology becomes outdated.
  • Lease deals on EVs are often very competitive due to manufacturer and dealer support.

Use the Cost4Cars Lease Calculator to compare EV lease costs against HP and PCP to find the right finance structure for your EV purchase.
