As electric vehicles become increasingly common across the UK, many drivers are asking the same question:
Is it cheaper to rely on public EV charging, or does installing a private charging station at home actually make more financial sense? Understanding EV charging station costs means looking beyond the upfront price. It involves comparing convenience, long-term running costs, reliability, and how prepared your property is for the future of transport.
This guide breaks down private vs public EV charging, explains real installation costs, and shows how to calculate whether a home EV charger delivers a return on investment.
Why EV Charging Costs Matter More Than Ever
EV adoption across London, Kent and the wider UK is accelerating. While this shift brings lower emissions and quieter roads, it also changes how households use electricity.
Charging behaviour is the key factor:
- Most EV owners charge in the evening
- Electricity demand is already highest at that time
- Public charging is priced for convenience, not efficiency
For regular drivers, the way you charge your vehicle has a direct impact on running costs. Installing a home EV charging station gives you control over when and how you charge. For most households, this is the most cost-effective long-term option. For a standard residential setup, EV charger installation costs usually fall within the following ranges:
- Total installed cost: £800 – £1,500
- Charger unit: £400 – £1,000
- Standard installation (7kW): £500 – £1,000
- Smart EV chargers: £1,000 – £1,200+ installed
A 7kW charger is suitable for most homes and will typically fully charge an EV overnight. A basic home installation usually covers:
- Charger mounting
- Connection to your existing electrical supply
- Safety devices and testing
- Commissioning and handover
However, not every property is the same, and additional work can increase costs. Some of the most common additional costs include:
- Longer cable runs:
If the charger is more than 10 metres from the meter, expect an extra £99–£189. - Underground cabling (trenching):
Typically around £30 per metre, depending on surface type. - Electrical upgrades:
Older consumer units, limited supply capacity, or earthing issues can significantly increase the final price.
This is why reputable installers always recommend a site survey before providing a fixed quote.
EV Charger vs Extension Cable
Smart chargers cost more upfront, but they unlock features that can dramatically reduce running costs. They also have convivence benefits; As Langley EC explains:
“A dedicated EV charger is faster, safer, and more convenient than using a standard 3-pin plug. It also allows you to make the most of cheaper energy tariffs and smart charging features.”
Also. why EV chargers are more expensive than a simple extension cable, there are grants available to help with the setup costs. While the main home grant for homeowners has ended, support is still available for certain property types.
As Diligent Electrical notes:
“The OZEV Homecharge Scheme offers up to £350 off the cost of installing a home EV charger. To qualify, the property must meet specific criteria, and an OZEV-approved installer must complete the installation.”
Scotland also offers additional funding options through regional schemes.
Public Vs Private EV Charging
| Factor | Private Charging | Public Charging |
|---|---|---|
| Upfront cost | Higher | None |
| Running cost | Low | High |
| Convenience | Charge at home | Dependent on availability |
| Speed consistency | Predictable | Variable |
| Long-term value | Strong | Limited |
Public EV charging removes installation costs entirely, but introduces higher ongoing expenses. Typical characteristics of public charging include:
- Higher per-kWh electricity rates
- Premium pricing for rapid and ultra-rapid chargers
- Subscription models tied to specific networks
Typically public charging works best for more occasional EV charging rather than relying on it if possible. However people living in flats (or lack space on their property) may rely on public chargers as their main source of EV refuelling. Long distance travellers will also need to regularly rely on public EV’s, preplanning their routes to avoid running out of fuel on their journey.
If you are business owner or a landlord you may consider installing a commercial EV chargers. While commercial EV charging costs are higher upfront, they can:
- Attract customers or tenants
- Generate revenue
- Improve property value and future readiness
Working with a qualified and highly rated electrical contractor would be very important if you are considering installing a commercial EV charging point. As SES Electrical Contractors put it:
“Specialists will inform you of the different possibilities to enable you to make a wise decision on ideal solutions for you and your business, within your budget.”
ROI Calculation: Is a Home EV Charger Worth It?
One of the most common questions homeowners ask is whether installing a private charger makes financial sense.
Here’s a simple way to calculate return on investment (ROI).
Step 1: Compare Charging Costs
Public charging example:
- Average cost: ~£0.70 per kWh
- Monthly usage: 300 kWh
- Monthly cost: £210
Home charging example (off-peak tariff):
- Average cost: ~£0.15 per kWh
- Monthly usage: 300 kWh
- Monthly cost: £45
Monthly saving: £165
Annual saving: £1,980
Step 2: Factor in Installation Costs
- Average home charger installation: £1,200
- OZEV grant (if applicable): –£350
- Net cost: £850
Step 3: Calculate Payback Period
£850 ÷ £1,980 = ~5 months
Even without a grant, many homeowners recover the cost of installation within 6–12 months, depending on mileage and tariffs.
After that, savings continue every year.
TLDR; EV Charging Station Costs
When comparing private vs public EV charging, the difference becomes clear over time.
Public charging offers flexibility, but private charging offers:
- Lower long-term costs
- Predictable charging
- Better use of smart tariffs
- A faster return on investment
As EV adoption continues to grow, installing a home charging station is less about convenience and more about future-proofing, provided it’s installed correctly.
