Checking Your UK Home's Electrical Capacity
Step 1: Locate Your Main Fuse Rating
Your main fuse (inside meter box/cutout) determines maximum supply:
- 60A fuse = 13.8kW maximum supply (adequate for 7kW charger with load management)
- 80A fuse = 18.4kW maximum supply (plenty for 7kW charger)
- 100A fuse = 23kW maximum supply (excellent, supports future expansion)
How to check: Look for printed rating on fuse carrier near your electricity meter (60A, 80A, or 100A printed on it)
Don't know? Contact your DNO for free supply check, or ask installer during site survey.
Step 2: Check Consumer Unit (Fuse Box) Capacity
Modern consumer units (post-2008): White plastic case, switches/MCBs, RCD test buttons
Old consumer units (pre-2008): Brown Bakelite case, fuse wire, no RCD protection
What you need for 7kW charger:
- At least one spare MCB slot (40mm width for 32A or 40A circuit breaker)
- Type A RCD protection minimum (Type B for some chargers like Zappi)
- Modern earthing system (TN-S or TN-C-S)
If your consumer unit is pre-2008 or full: Budget £400-£800 for upgrade (32% of UK installations need this)

- This is normal - smart charging delays until cheapest electricity window
11:30 PM: Charging begins automatically
- Octopus Intelligent starts charging (7.5p/kWh window opens)
- Charger light changes (typically green/blue pulsing = active charging)
- App shows "Charging" + current power (e.g., "Charging at 7kW")
- EV dashboard shows charging rate and estimated completion time
12:00 AM - 5:30 AM: Charging overnight
- 7kW charger adds 42kWh over 6 hours
- = 150-180 miles range added (depending on EV efficiency)
- Total cost: 42kWh x £0.075 = £3.15 (vs £18.90 at rapid charger)
5:30 AM: Charging completes
- Smart charging window closes
- Charger stops automatically (reached target 80% charge)
- App notification: "Charging complete"
- EV ready for morning commute
7:00 AM: Unplug and drive
- Unplug cable from car
- Cable management: hang on charger hook or store in car boot
- Drive away with 80% charge
Understanding Your Charger Lights (UK Standards)
Most UK chargers use similar light codes:
Solid Blue/Green: Ready to charge (plugged in, waiting for scheduled time)
Pulsing Blue/Green: Actively charging
Solid White: Fully charged (target reached)
Flashing Red/Orange: Error (check app for details)
No Light: Charger powered off or not connected
Specific charger guides:
- Ohme: Solid blue = ready, pulsing blue = charging
- Zappi: RGB light ring (green = eco/solar, blue = fast charge)
- Wallbox: LED ring (blue = charging, green = ready)
Part 7: Maximizing Your UK Home Charging Setup
Solar Panel Integration (2026 UK Guide)
Why solar + EV charging is brilliant:
- Solar panels generate 900-1,200kWh/year per kW installed (UK average)
- 4kW solar system = 3,600-4,800kWh/year
- EV uses 3,600kWh/year (12,000 miles at 3 miles/kWh)
- = 60-80% of EV charging can be free from solar (April-September)
Best solar-integrated chargers:
- Zappi (ECO+ mode = solar-only charging)
- Easee One (solar excess prioritization)
- Wallbox Pulsar Plus (solar mode available)
Realistic solar charging (UK 4kW system, 2026):
Summer (April-September):
- Solar generation: 400-600kWh/month
- EV charging: 300kWh/month
- Result: 80% free solar charging, 20% grid top-up
Winter (October-March):
- Solar generation: 50-150kWh/month
- EV charging: 300kWh/month
- Result: 25% solar, 75% cheap overnight grid
Annual Economics:
- Solar EV charging: 2,160kWh/year x £0 = £0
- Grid EV charging: 1,440kWh/year x £0.075 = £108
- Total annual cost: £108 (vs £864 without solar = 87% saving)
Solar system cost: £5,000-£7,000 (4kW system, 2026 average)
Payback with EV: 12-15 years (combined household + EV savings)
Load Management for Weak UK Supplies
If you have 60A main fuse + high household electrical load:
Problem: 7kW charger (32A) + electric heating (20A) + cooking (25A) = 77A total = exceeds 60A supply
Solution: Load management chargers (Zappi, Easee, Ohme)
How it works:
- CT clamp monitors household electricity use in real-time
- Charger calculates: 60A supply - 40A household use = 20A available for EV
- Charger adjusts dynamically (20A = 4.6kW charging vs 7kW maximum)
- When household load drops overnight, charger increases to full 7kW
Result: No DNO upgrade needed (save £0 cost + 8-16 week wait), full overnight charging achieved
Cost: Load management setup £100-£250 (CT clamp installation + configuration)
Two EVs, One Home: Dual Charging Solutions
UK households with 2 EVs (growing 38% year-on-year):
Option 1: Sequential Charging (One Charger)
- Install one 7kW charger (£999)
- Charge EV #1: 6pm-12am (6 hours = 42kWh)
- Charge EV #2: 12am-6am (6 hours = 42kWh)
- Total cost: £999
- Works if: Both EVs don't need full charge every night
Option 2: Dual Chargers with Load Balancing (Recommended)
- Install two 7kW chargers (£1,800-£2,200 with dual installation discount)
- Load balancing system coordinates power (Zappi Link, Easee Equalizer)
- Both EVs charge simultaneously, sharing available 7kW (3.5kW each)
- When one EV reaches target, other gets full 7kW
- Total cost: £1,800-£2,200
- Benefit: Convenience, both cars always ready
See our guide: Shared Driveway EV Charging for dual installation cost-sharing strategies
Part 8: Common UK Home Charging Mistakes to Avoid
Top 10 Costly Mistakes (2026 Edition)
1. Choosing Charger Based on Price Alone
❌ Mistake: Buying cheapest £350 basic charger
✅ Better: Spend £499-£649 for smart charger (Ohme, Wallbox) = save £500-£600/year via smart tariffs
Net saving: Smart charger pays for itself in 3-6 months
2. Skipping Site Survey
❌ Mistake: Accepting quote without site visit
✅ Better: Insist on free site survey (identifies hidden costs: consumer unit upgrade £400-£800, long cables £150-£500)
34% of UK installations discover issues during survey that weren't in initial quote
3. Not Checking OZEV Approval (If Eligible for Grant)
❌ Mistake: Using non-OZEV installer to save £100
✅ Better: Use OZEV-approved installer = eligible for £350-£750 grants (flats, rental properties, Scotland EST grants)
Potential loss: £350-£750 grant forfeited
4. Ignoring Smart Tariffs
❌ Mistake: Charging on standard 24p/kWh rate
✅ Better: Switch to Octopus Intelligent 7.5p/kWh
Annual waste: £594/year (12,000 miles)
5. Wrong Cable Length
❌ Mistake: 5m tethered cable (charger 6m from parking spot = cable won't reach)
✅ Better: Measure parking distance, choose 7.5m or 10m cable option (£80-£150 upgrade)
Cost to fix: £200-£400 (charger relocation or cable replacement)
6. Overlooking WiFi Coverage
❌ Mistake: Installing smart charger in garage with no WiFi signal
✅ Better: Check WiFi strength before installation, install WiFi extender (£20-£60) if needed
Result: Smart features unusable, £500+ charger becomes basic "dumb" charger
7. Not Future-Proofing for Solar
❌ Mistake: Installing basic charger, planning solar panels in 2 years
✅ Better: Spend extra £200-£400 for solar-ready charger (Zappi, Easee) now
Cost to fix later: £400-£800 (charger replacement + reinstallation)
8. DIY Installation Attempt
❌ Mistake: Installing charger yourself to save money
✅ Better: Use certified Part P electrician (legal requirement)
Consequences:
- Building Regulations violation (£5,000+ fine)
- Home insurance void
- DNO notification impossible (illegal to use)
- Resale value impact
Never worth the £250-£400 "saving"
9. Charging to 100% Daily
❌ Mistake: Always charging EV to 100%
✅ Better: Set limit to 80% for daily use (100% only for long trips)
Why: Charging to 80% extends battery life 20-30% (EV batteries degrade faster at high states of charge)
Cost impact: Battery replacement £8,000-£15,000 comes 2-3 years sooner
10. Not Reading Installation Certificate
❌ Mistake: Binning installation certificate
✅ Better: Keep certificate safe (needed for home sale, insurance claims, warranty)
If lost: £100-£200 to get retrospective certificate issued
Frequently Asked Questions (2026 UK Edition)
How much does home EV charging cost in the UK?
Standard electricity rate: 24-34p/kWh = £8.64-£12.24 for 200 miles
Smart EV tariff (Octopus Intelligent): 7.5p/kWh = £2.70 for 200 miles
With solar panels: 0-7.5p/kWh blended = £0-£2.70 for 200 miles (60-80% free solar in summer)
For 12,000 miles/year: £270-£864 annually (depending on tariff) vs £1,800-£2,400 public rapid charging = 70-85% cheaper
How long does home EV charging take?
3.7kW charger: 12-15 miles/hour = 13-16 hours for full charge (40kWh battery)
7kW charger (UK standard): 25-30 miles/hour = 6-8 hours for full charge = overnight charging perfect
22kW charger (three-phase): 75-90 miles/hour = 2-3 hours full charge (but limited by EV's onboard charger - most max at 7-11kW AC)
Bottom line: 7kW overnight charging is perfectly sufficient for 95% of UK EV owners (wake up to 200+ miles range every morning)
