- Petrol cost: £1,320/year
- Saving: £1,154/year
Owner comment:
"My electricity bill went up £14/month, but I'm saving £100/month on petrol. I use a credit card that offers 5% cashback on fuel, so I actually miss that, but still saving £95/month net. Wish I'd switched years ago." - Sarah, Lewisham
Example 2: Tesla Model 3 LR - High Mileage
Owner: James, Manchester, sales rep, high mileage
Vehicle efficiency: 3.2 mi/kWh (motorway-heavy driving reduces efficiency) Annual mileage: 25,000 miles Annual consumption: 7,813kWh
Charging setup:
- Home (Octopus Intelligent Go, 7p/kWh): 60%
- Tesla Supercharger off-peak (45p/kWh): 30%
- Tesla Supercharger peak (67p/kWh): 10%
Annual cost:
- Home: 4,688kWh × £0.07 = £328
- Supercharger off-peak: 2,344kWh × £0.45 = £1,055
- Supercharger peak: 781kWh × £0.67 = £523
- Total: £1,906/year
Previous car (BMW 320d, 55mpg diesel):
- Diesel cost (£1.55/L): £3,182/year
- Saving: £1,276/year
Owner comment:
"High mileage means lots of Supercharger use, which isn't cheap. But I'm still saving £100+/month vs my old diesel. The key is charging at home overnight whenever possible—that's where the real savings are. Supercharging is convenient but expensive." - James, Stockport
Example 3: MG4 EV - No Home Charging
Owner: Emma, Brighton, terraced house, street parking only
Vehicle efficiency: 3.9 mi/kWh Annual mileage: 8,000 miles Annual consumption: 2,051kWh
Charging setup:
- Lidl free (while shopping, 2-3 times/week): 40%
- Council lamppost (38p/kWh): 40%
- Public rapid (65p/kWh, emergencies): 20%
Annual cost:
- Lidl free: 820kWh × £0 = £0
- Lamppost: 820kWh × £0.38 = £312
- Rapid: 410kWh × £0.65 = £267
- Total: £579/year
Previous car (Renault Clio 1.0 TCe, 55mpg):
- Petrol cost: £955/year
- Saving: £376/year
Owner comment:
"I won't lie, it's more hassle than having a driveway. I plan my Lidl shops around charging (usually get 60% charge in 90 minutes while shopping). Lamppost chargers near my house are hit-or-miss on availability. But I'm still saving £30/month, and I love the MG4. Just requires more planning than home charging." - Emma, Brighton
Cost Optimization Strategies
Strategy 1: Maximize Off-Peak Home Charging
Tactic: Switch to EV-specific tariff, charge 100% overnight
Implementation:
- Switch to Octopus Intelligent Go (7p/kWh off-peak)
- Set charger schedule: 11:30pm-5:30am
- Plug in every night, even for small top-ups
Savings:
- Standard tariff (24.5p/kWh): £700/year
- Octopus off-peak (7p/kWh): £200/year
- Annual saving: £500
Effort: 5 minutes to switch tariff, zero ongoing effort (automated charging)
ROI: 6000% (£500 saving for £8 time investment)
Strategy 2: Exploit Free Destination Charging
Tactic: Charge at free destination chargers (supermarkets, gyms, hotels)
Free charging locations (2025):
- Lidl: Free 22kW charging (while shopping, 90 min limit)
- Aldi: Free 7-22kW (some locations, being phased out)
- Hotels: Travelodge, Premier Inn (free for guests)
- Gyms: Some Pure Gym, David Lloyd (members)
Realistic potential:
- Weekly Lidl shop (90 min charge): ~15kWh/week = 780kWh/year
- Value at 7p/kWh: £55/year
- Value at 24.5p/kWh: £191/year
Effort: Minimal (shop where you charge)
Caveat: Free charging is disappearing. Lidl is last major holdout. Don't rely on this long-term.
Strategy 3: Workplace Charging Advocacy
Tactic: Convince your employer to install workplace chargers
Business case for employer:
- Government Workplace Charging Scheme: £350 grant per socket (up to 40 sockets)
- Attracts EV-driving employees (recruitment/retention)
- CSR benefits (sustainability credentials)
Your pitch:
- Research WCS grant: £350/socket
- Poll colleagues: How many have/plan EVs?
- Email facilities/HR with business case
- Offer to lead project (shows initiative)
Potential savings:
- Free workplace charging (5 days/week): ~£400/year
ROI: 30 minutes to write email, potentially £400/year savings
Strategy 4: Avoid Rapid Charging (Except Essentials)
Tactic: Plan charging to minimize expensive rapid charging use
Rules:
- Never rapid charge for local journeys - use home/destination
- Pre-charge before long trips - start with 100% from home (7p/kWh)
- Minimize motorway rapids - charge at destination if possible
- Use Tesla Superchargers off-peak (if Tesla owner) - 45p vs 67p peak
Example:
-
Bad: Regular 50-mile round trips, rapid charge halfway at 65p/kWh
- Cost per trip: £2.60
- Annual (50 trips): £130
-
Good: Charge overnight at home before trip at 7p/kWh
- Cost per trip: £0.28
- Annual (50 trips): £14
- Saving: £116/year
Effort: Planning (charge to 100% night before long journeys)
Strategy 5: Join Charging Network Subscriptions (If Heavy User)
For frequent public chargers:
BP Pulse Subscription:
- Cost: £7.85/month (£94/year)
- Benefit: 55p/kWh rapids (vs 69p non-members)
- Break-even: 56kWh/month rapid charging
- Worth it if: You rapid charge 15+ times/year
Ionity Passport:
- Cost: £10.99/month (£132/year)
- Benefit: 69p/kWh (vs 74p non-members)
- Limited benefit unless heavy motorway user
Verdict: Only subscribe if you rapid charge 20+ times/year. Most home-charging EV owners shouldn't subscribe.
Future Cost Predictions (2025-2030)
What's Likely to Increase
Public Charging Costs ⬆️
- Current trend: +5-10p/kWh per year
- 2025: 65-79p/kWh rapids
- 2027 prediction: 75-90p/kWh
- Reason: Infrastructure costs, profit margins normalizing
Home Standard Rates ⬆️
- Energy crisis volatility continues
- 2025: 24-28p/kWh standard
- 2027 prediction: 28-35p/kWh
- EV tariff off-peak rates more stable (7-12p/kWh)
What's Likely to Decrease
Competition Driving Down Costs ⬇️
- Tesla Supercharger network opening to all EVs (2025+)
- Increased competition at motorway services
- Prediction: Premium rapid charging may plateau at 75-80p/kWh
Council Chargers Becoming Free/Subsidised ⬇️
- Government pushing councils to support EV transition
- More free lamppost charging (like Camden model)
- Prediction: 20-30% of council chargers free by 2027
Net Impact
Best case (home charging): Savings vs petrol remain strong (£1,200-£1,500/year) Worst case (kerbside reliance): Gap narrows (£300-£500/year savings vs petrol)
Bottom line: Home charging will remain dramatically cheaper than petrol. Public-only charging will become less attractive unless infrastructure costs drop.
Conclusion: Where You Charge Determines Your Savings
The EV cost hierarchy (cheapest to most expensive):
- Workplace charging (free): £0/year 🥇
- Home off-peak charging (7-9p/kWh): £200-£260/year 🥈
- Home standard charging (24p/kWh): £685/year 🥉
- Destination slow charging (30-50p/kWh): £860-£1,430/year
- Council kerbside (35-45p/kWh): £1,000-£1,285/year
- Public rapid charging (55-79p/kWh): £1,571-£2,257/year ❌
Golden rule: Access to home charging transforms EV economics from "marginal savings" to "massive savings."
Realistic UK EV owner:
- 80% home off-peak (7p/kWh)
- 15% public slow/rapid (40-65p/kWh)
- 5% destination (35p/kWh)
- Annual cost: £400-£500
- Saving vs petrol: £1,150-£1,250/year
After 5 years of EV ownership: £5,750-£6,250 total savings vs petrol
Final verdict: For UK homeowners with driveways and smart tariffs, EV charging costs are negligible (£17/month). Even without home charging, EVs still save money vs petrol—just not as dramatically. The infrastructure you have access to determines whether EV ownership is brilliant or just okay.
