EV Charger Payback Period: How Quickly It Pays Off
The Short Answer: 3–8 Months
A home EV charger typically pays for itself in 3–8 months. Three variables set the pace:
- The installed cost of the charger
- What you’d otherwise pay to charge (Supercharger, public rapid, 3-pin at peak rates)
- Whether you’re on an off-peak tariff
After payback, every charge is pure savings against the alternative. Over five years, the savings run into thousands of pounds.
How the Payback Calculation Works
The formula: total installed cost ÷ monthly savings = months to break even.
A worked 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
A caveat in the drivers' favour: most people switching to an off-peak tariff for EV charging save on household electricity too, so the real payback is quicker than the figure above.
Payback at Different Price Points
Payback for each charger against the 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 |
On rapid at 79p/kWh, a home charger on an off-peak tariff pays back in as little as 5 months.
vs Standard Home Tariff (24.5p/kWh → 7p/kWh off-peak)
Even coming from a 3-pin plug on standard rates, the move to a proper charger on an off-peak tariff saves materially:
| 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
The charger is a one-time cost; the tariff savings compound every month, and it is the tariff — not the unit itself — that does most of the work on payback.
Our cost breakdown post sets out the full pence-per-mile table across Supercharger, public rapid, standard and off-peak home tariffs. The short version for payback purposes: switching from Supercharging to off-peak home charging saves roughly £914/year; from public rapid to off-peak home, £2,057/year. See the tariff comparison or the best EV charging tariffs guide for current rates.
OZEV Grant Impact
Renters and flat owners qualify for the OZEV grant, which covers up to £500 of the installed cost. That shortens payback sharply:
| 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 grant, the cheapest chargers pay back in 3–5 months.
Low-Mileage Drivers: Is It Still Worth It?
Lower mileage means longer payback, but the economics hold 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 |
At 5,000 miles a year, the charger still pays back inside two years — and saves £456/year thereafter.
5-Year Total Cost of Ownership
Total charging cost across five years at 10,000 miles per 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
