Congratulations on your new electric vehicle! Whether you've just collected your first EV or you're picking it up next week, this guide will help you set up home charging the right way.
Home charging is the backbone of EV ownership—90% of UK EV owners do most of their charging at home. Get it right from the start, and you'll enjoy years of convenient, low-cost motoring.
This guide covers: What you need to know in your first 30 days of EV ownership, from temporary charging solutions to permanent home charger installation.
Week 1: The Essentials
What Comes With Your New EV
Most new EVs include:
- Type 2 charging cable (5m) - For public AC chargers
- Granny cable/EVSE - 3-pin plug charger for emergencies (not all brands)
- Quick start guide - Basic charging instructions
- App access - Manufacturer's app for remote monitoring
Check what's included: Some manufacturers (notably Tesla UK) no longer include cables. Verify before delivery and budget £200-£400 for cables if needed.
Day 1: Emergency Charging Setup
Before your home charger is installed (typically 2-4 weeks), you need a temporary solution:
Option 1: Granny Cable (3-Pin Plug)
If your EV came with a granny cable:
- Provides 2.3kW charging (about 8-10 miles per hour)
- Use only on a dedicated socket, ideally outdoor weatherproof type
- Don't use extension leads (fire risk)
- Check socket and plug regularly for heat buildup
- Suitable for low-mileage drivers (<30 miles/day)
⚠️ Warning: Granny cables are for emergency/temporary use only. They stress household wiring when used daily.
Option 2: Portable Smart Charger
If you'll be without a home charger for a while, consider:
- Ohme Go (~£350) - Smart scheduling, 7kW capable
- Granny+ units (~£300-£500) - Safer than basic granny cables
- Can be upgraded to commando plug for 7kW (requires electrician)
Option 3: Public Charging
Find local public chargers for the first few weeks:
- Download Zap-Map app (essential UK charging map)
- Locate free chargers (Lidl, Aldi, IKEA, some Tesco)
- Sign up for major networks: BP Pulse, Shell Recharge, Pod Point
Day 2-7: Start Planning Your Home Charger
Don't delay—installation takes 2-6 weeks from first enquiry:
- Research charger options (see section below)
- Get 3 quotes from installers
- Check your consumer unit - Installers will assess during survey
- Book installation - Weekday slots usually faster than weekends

Setting Up Smart Charging
Why Smart Charging Matters
Smart charging saves you £400-£600 per year by automatically charging when electricity is cheapest:
Without smart charging:
- Plug in at 6pm, charge immediately at 28p/kWh
- Cost for typical use (2,500kWh/year): £700
With smart charging:
- Plug in at 6pm, charges automatically from 11:30pm at 7p/kWh
- Cost for typical use: £175
- Annual saving: £525
The Best Smart Tariff: Octopus Intelligent Go
Most new EV owners should get Octopus Intelligent Go:
- Rate: 7p/kWh overnight (vs ~28p/kWh standard)
- Hours: 11:30pm - 5:30am (6 hours guaranteed)
- Smart slots: Extra cheap hours during day when grid is quiet
- Requirement: Compatible charger (Ohme, Wallbox, Zappi, etc.) or specific car
How to sign up:
- Visit Octopus Energy (use referral link for £50 credit)
- Select Intelligent Go tariff
- Link your charger or car in the app
- Set your departure time—Octopus handles the rest
Setting Up Your Charger App
Week 1 setup tasks:
- Download manufacturer's app (Wallbox, Ohme, myenergi, etc.)
- Create account and pair with charger
- Connect charger to your WiFi
- Set default charge schedule (e.g., 11:30pm - 5:30am)
- Set charge limit (80% for daily use extends battery life)
- Enable notifications (charge complete, errors)
First Month: Building Good Habits
Daily Routine
The "Always Plugged In" approach:
Most EV experts recommend plugging in whenever you're home, even if you don't need a full charge:
- Battery management systems work best when connected
- You're always ready for unexpected trips
- Smart charging ensures you only charge when cheap
- No range anxiety—car is always ready
Don't worry about:
- Overcharging (the car manages this automatically)
- Battery degradation from frequent plugging (it's designed for this)
- Electricity waste (smart chargers don't draw power when not needed)
Charging Level: 80% vs 100%
Daily use: Set charge limit to 80%
- Extends battery lifespan
- Plenty of range for daily driving
- Most manufacturers recommend this
Before long trips: Charge to 100%
- Set in app the night before
- Or override manually when needed
- Use within a few hours of reaching 100%
Understanding Your Charging Costs
Track these in month 1:
- kWh added - Your charger app shows this
- Electricity cost - kWh × your rate (e.g., 1,000kWh × 7p = £70)
- Cost per mile - Divide total cost by miles driven
Typical new EV owner (1,000 miles/month):
- kWh used: ~280kWh
- Smart tariff cost (7p/kWh): £19.60
- Cost per mile: 1.96p
- Equivalent petrol cost would be: ~£130 (at 40mpg, £1.45/litre)
Common New Owner Mistakes to Avoid
Mistake 1: Waiting Too Long to Install a Home Charger
Using a granny cable for months risks:
- Electrical fires from overloaded circuits
- Higher charging costs (no smart tariff benefits)
- Inconvenience and slower charging
Fix: Order your home charger within the first week.
Mistake 2: Not Switching to an EV Tariff
Staying on a standard tariff costs £500+/year extra:
| Tariff | kWh Rate | Annual Cost (10,000 miles) |
|---|---|---|
| Standard variable | 28p | £800 |
| Octopus Intelligent Go | 7p | £200 |
| Saving | - | £600 |
Fix: Switch to Octopus Intelligent Go (or similar) immediately after getting your EV.
Mistake 3: Range Anxiety Overcharging
New owners often charge to 100% every night "just in case":
- Accelerates battery degradation
- Unnecessary if you're not driving far
- Wastes money (charging you don't use)
Fix: Set 80% limit for daily use. Only charge to 100% before long trips.
Mistake 4: Ignoring Scheduled Charging
Plugging in and charging immediately:
- Costs 3-4x more than off-peak rates
- Strains the grid during peak times
- Misses the key benefit of smart chargers
Fix: Set up scheduled charging in your charger app. Plug in anytime; it waits for cheap rates automatically.
Mistake 5: Not Mapping Local Public Chargers
Relying 100% on home charging means:
- No backup if home charger fails
- Missing free charging opportunities (Lidl, Aldi, etc.)
- Panic on longer trips
Fix: Download Zap-Map and locate 3-5 backup chargers near home and work.
Month 2 and Beyond: Optimisation
Monitor and Improve
Monthly review:
- Check total kWh charged (charger app)
- Calculate actual cost per mile
- Compare to expected costs
- Adjust charge limit if needed
Consider These Upgrades
If you have solar panels:
- Consider Zappi charger for solar diversion
- Or enable solar-aware scheduling in your charger app
If you're a high-mileage driver:
- Ensure your charger is 7kW (not limited to 3.6kW)
- Consider second charger if you have two EVs
If you want maximum savings:
- Try Octopus Agile tariff (variable rates, sometimes negative)
- Install home battery storage (advanced, expensive)

Frequently Asked Questions
How much does it cost to charge an EV at home?
With a smart tariff like Octopus Intelligent Go (7p/kWh), charging costs approximately £2.80-£4.20 for 40-60kWh (a full charge for most EVs). This gives 200-300 miles of range. On a standard tariff (28p/kWh), the same charge costs £11.20-£16.80.
Do I need a special electricity supply for a home charger?
No. A standard UK single-phase domestic supply (60-100A main fuse) easily accommodates a 7kW charger. Your installer will check this during the survey. Three-phase supply is only needed for 22kW chargers, which aren't necessary for most homes.
Can I install an EV charger myself?
No. UK law requires EV chargers to be installed by a qualified electrician registered with a competent person scheme (NICEIC, NAPIT, etc.). DIY installation is illegal under Building Regulations Part P and potentially dangerous.
How long does a home charger take to install?
Typical installation takes 3-5 hours. The whole process from enquiry to installation is usually 2-4 weeks, depending on installer availability and any DNO approvals needed.
What happens if I don't have off-street parking?
Home charger installation requires off-street parking. Without it, options include:
- Workplace charging
- Public charging networks
- On-street residential chargers (where councils install them)
- Cable gullies (where permitted)
See our guide on charging without a driveway for details.
Should I charge every day or wait until the battery is low?
Charge whenever convenient—modern EV batteries are designed for frequent charging. The "always plugged in when home" approach is recommended. Smart charging ensures you only pay cheap rates regardless of when you plug in.
