EV Charger Payback Period: How Quickly Does a Home Charger Pay for Itself?
The Short Answer: 3–8 Months
A home EV charger typically pays for itself in 3–8 months, depending on:
- What you paid for the charger and installation
- What you’d otherwise be paying to charge (Supercharger, public rapid, 3-pin at peak rates)
- Whether you’re on an off-peak electricity tariff
After the payback period, every charge is pure savings compared to the alternative. Over 5 years, the savings add up to thousands of pounds.
How the Payback Calculation Works
The formula is straightforward:
Total installed cost ÷ Monthly savings = Months to break even
Let’s work through a real example:
- Charger installed cost: £950 (mid-range charger + standard installation)
- Monthly driving: 833 miles (10,000 miles/year)
- Energy consumption: 238 kWh/month (at 3.5 miles per kWh)
- Home off-peak charging cost: £16.67/month (at 7p/kWh)
- Supercharger cost: £92.82/month (at 39p/kWh)
- Monthly saving: £76.15
Payback period: £950 ÷ £76.15 = 12.5 months
But if you factor in that you’d likely switch to an off-peak tariff regardless (saving money on all your home electricity, not just EV charging), the real payback is even faster.
Payback at Different Price Points
Here’s how quickly different chargers pay for themselves vs three common alternatives:
vs Tesla Supercharger (39p/kWh → 7p/kWh off-peak)
| Charger | Installed Cost | Monthly Saving | Payback |
|---|---|---|---|
| Sync Energy (£362) | £862 | £76 | 11 months |
| Easee One (£405) | £905 | £76 | 12 months |
| Tesla Wall Connector (£425) | £925 | £76 | 12 months |
| Ohme Home Pro (£535) | £1,035 | £76 | 14 months |
| Hypervolt Home 3 Pro (£690) | £1,190 | £76 | 16 months |
*Installation cost estimated at £500 (mid-range). Your actual cost depends on cable run length and consumer unit.*
vs Public Rapid Charging (79p/kWh → 7p/kWh off-peak)
| Charger | Installed Cost | Monthly Saving | Payback |
|---|---|---|---|
| Sync Energy (£362) | £862 | £171 | 5 months |
| Easee One (£405) | £905 | £171 | 5 months |
| Tesla Wall Connector (£425) | £925 | £171 | 5 months |
| Ohme Home Pro (£535) | £1,035 | £171 | 6 months |
| Hypervolt Home 3 Pro (£690) | £1,190 | £171 | 7 months |
If you’ve been relying on public rapid chargers at 79p/kWh, a home charger on an off-peak tariff pays for itself in as little as 5 months.
vs Standard Home Tariff (24.5p/kWh → 7p/kWh off-peak)
Even if you’re already charging at home on a 3-pin plug at standard rates, switching to a proper charger on an off-peak tariff saves significantly:
| Charger | Installed Cost | Monthly Saving | Payback |
|---|---|---|---|
| Sync Energy (£362) | £862 | £42 | 21 months |
| Easee One (£405) | £905 | £42 | 22 months |
| Tesla Wall Connector (£425) | £925 | £42 | 22 months |
*Saving = the difference between 24.5p and 7p per kWh at 238 kWh/month.*
The Tariff Multiplier
Your electricity tariff has a massive impact on payback. The charger is a one-time cost; the tariff savings compound every single month.
| Scenario | Cost per 100 Miles | Annual Cost (10,000 mi) |
|---|---|---|
| Public rapid (79p/kWh) | £22.57 | £2,257 |
| Supercharger (39p/kWh) | £11.14 | £1,114 |
| Home, standard tariff (24.5p/kWh) | £7.00 | £700 |
| Home, off-peak tariff (7p/kWh) | £2.00 | £200 |
Switching from Supercharging to off-peak home charging saves £914/year. Switching from public rapid to off-peak home saves £2,057/year. The tariff is where the real money is.

OZEV Grant Impact
If you’re a renter or flat owner, the OZEV grant covers up to £500 of your installation cost. This dramatically accelerates payback:
| Charger | Without Grant | With £500 Grant | Payback Improvement |
|---|---|---|---|
| Sync Energy (£362) | £862 | £362 | 5 months faster |
| Easee One (£405) | £905 | £405 | 7 months faster |
| Tesla Wall Connector (£425) | £925 | £425 | 7 months faster |
| Ohme Home Pro (£535) | £1,035 | £535 | 7 months faster |
*Payback vs Supercharger at 10,000 miles/year on 7p/kWh off-peak tariff. Grant-adjusted figures assume full £500 grant applied.*
With the OZEV grant, the cheapest chargers can pay for themselves in as little as 3–5 months.
Low-Mileage Drivers: Is It Still Worth It?
The lower your mileage, the longer the payback — but it’s still worth it for virtually every driver:
| Annual Mileage | Monthly kWh | Monthly Saving (vs Supercharger) | Payback (£950 charger) |
|---|---|---|---|
| 5,000 miles | 119 kWh | £38 | 25 months |
| 8,000 miles | 190 kWh | £61 | 16 months |
| 10,000 miles | 238 kWh | £76 | 12 months |
| 12,000 miles | 286 kWh | £91 | 10 months |
Even at just 5,000 miles per year, the charger pays for itself within 2 years — and then saves you £456/year for every year after that.
5-Year Total Cost of Ownership
Let’s zoom out and look at the total charging cost over 5 years at 10,000 miles/year:
| Method | Year 1 | Years 2–5 | **5-Year Total** |
|---|---|---|---|
| Home charger + off-peak | £1,150* | £800 | £1,950 |
| Supercharger only | £1,114 | £4,456 | £5,570 |
| Public rapid only | £2,257 | £9,028 | £11,285 |
*\*Year 1 includes £950 charger installation + £200 charging costs.*
5-year savings vs Supercharging: £3,620
5-year savings vs public rapid: £9,335
