Everything Central Scotland homeowners need to know about installing a home EV charger, from charger types and costs to grants, electrical requirements, and finding an approved installer.
With electric vehicle sales surging across Scotland and the 2035 ban on new petrol and diesel cars approaching, installing a home EV charger is becoming a priority for homeowners in Glasgow, Edinburgh, Stirling, and across Central Scotland. Here's your complete guide to making the switch from slow three-pin charging to a dedicated home wallbox.
Types of Home EV Charger
Not all EV chargers are created equal. The three main options for domestic installations differ significantly in speed, cost, and electrical requirements:
| Charger Type | Power Output | Charge Time (typical 60kWh battery) | Cost Installed | Electrical Requirements |
|---|---|---|---|---|
| Slow (3-pin plug) | 2.3kW | 24–30 hours | None (uses existing socket) | Standard 13A socket |
| Fast (single-phase wallbox) | 7kW | 8–10 hours | £800–£1,200 | Dedicated 32A circuit from consumer unit |
| Rapid (three-phase) | 22kW | 3–4 hours | £2,500–£4,000+ | Three-phase supply (rare in domestic settings) |
For most Central Scotland homes, a 7kW single-phase wallbox is the ideal choice. It provides a full overnight charge for virtually any EV, works with the standard single-phase electricity supply found in most Scottish homes, and represents excellent value for money.
OZEV Grants and Financial Support
EV Chargepoint Grant
The Office for Zero Emission Vehicles (OZEV) offers grants of up to £350 towards the cost of installing a home chargepoint. To qualify, you must own an eligible electric vehicle and have off-street parking where the charger can be installed. The grant is applied directly by your installer, reducing the upfront cost. Your installer must be OZEV-approved — not all electricians hold this accreditation, so check before booking.
Energy Saving Trust Scotland
Scottish homeowners may also be eligible for additional support through Energy Saving Trust Scotland programmes and interest-free loans for home energy improvements. Check the latest eligibility criteria as these programmes update regularly.
Installation Requirements
Before booking an installation, ensure your property meets these requirements:
- Off-street parking: The charger must be installed on a wall, post, or structure adjacent to where you park, with the cable reaching your vehicle's charge port
- Adequate electrical supply: Your main fuse must be sufficient to support the additional load — typically 80A or 100A for a 7kW charger alongside normal household demand
- Consumer unit capacity: A spare way is needed in your consumer unit, or it may need upgrading
- Wi-Fi signal: Smart chargers require a Wi-Fi connection for app control and smart tariff integration
- Planning permission: Usually not required for a wall-mounted charger, but check with your local authority if you're in a conservation area or listed building
Smart Charging Features
Modern EV chargers are smart devices that do far more than simply supply electricity:
- Scheduled charging: Set your car to charge during off-peak electricity hours (typically midnight to 5am) when rates can be as low as 7p/kWh on specialist EV tariffs
- App control: Monitor charging status, costs, and energy usage from your smartphone
- Load management: The charger automatically reduces its output when other household appliances are drawing heavy loads, preventing your main fuse from tripping
- Solar integration: Some chargers can integrate with home solar panels to charge your EV using free solar energy
The Installation Process
A typical home EV charger installation takes 2–4 hours and follows these steps:
- Site survey: Your installer assesses your electrical supply, consumer unit, cable route, and charger location
- Cable routing: A dedicated circuit is run from your consumer unit to the charger location, typically through the loft or along an external wall
- Charger mounting: The wallbox is securely fixed to the wall at an appropriate height
- Electrical connection: The charger is connected to the dedicated circuit with appropriate protection in the consumer unit
- Testing and commissioning: The installation is tested, the charger is connected to Wi-Fi, and you're shown how to use it
- Certification: An Electrical Installation Certificate is issued and, if applicable, the OZEV grant paperwork is submitted
Running Costs
Charging at home is significantly cheaper than petrol or diesel. On a standard electricity tariff at around 24p/kWh, a full 60kWh charge costs approximately £14.40 — enough for 200+ miles. On a specialist EV tariff with overnight rates of 7p/kWh, the same charge costs just £4.20. Compare this to filling a similar-sized petrol car at £70–£80, and the savings are substantial.
Frequently Asked Questions
Can I install an EV charger myself?
No. EV charger installation involves working with high-current circuits and must be carried out by a qualified electrician. For OZEV grant eligibility, the installer must also be OZEV-approved. This is notifiable electrical work under Scottish Building Standards.
What if I don't have off-street parking?
Unfortunately, home charger installation requires off-street parking. If you park on the street, you'll need to rely on the growing network of public chargers across Central Scotland. Some local authorities are installing on-street residential chargepoints — check with Glasgow, Edinburgh, Stirling, or your local council for plans in your area.
Will an EV charger increase my property value?
Evidence suggests that a home EV charger can add value to your property and make it more attractive to buyers, particularly as EV adoption accelerates. It's increasingly seen as a desirable feature, much like a good broadband connection.
Do I need to upgrade my electricity supply?
Most homes with a 100A main fuse can support a 7kW charger without issues. If your main fuse is rated at 60A (common in older Scottish properties), you may need your electricity supplier to upgrade it — this is usually free but can take several weeks. Your installer will check this during the site survey.
