Electric vehicles (EVs) are becoming increasingly popular across the UK, and with that growth comes the need for convenient and reliable charging solutions at home. Installing a car charger at your property offers the convenience of charging overnight and can save money compared to public charging stations. But how much does it cost to install a car charger in the UK? This post breaks down the typical expenses, factors influencing the price, and what you should expect throughout the installation process.
What Types of Car Chargers Are Available for Home Installation?
Before diving into costs, it helps to understand the main types of chargers you can install:
Slow Chargers (3kW to 6kW): These use a standard single-phase supply and are the cheapest option. They typically add 10-20 miles of range per hour of charging.
Fast Chargers (7kW to 22kW): These require a three-phase supply and charge much faster, adding 30-60 miles of range per hour. They cost more to install but offer greater convenience.
Smart Chargers: These chargers connect to Wi-Fi or apps, allowing you to schedule charging during off-peak hours or monitor usage. They usually come at a premium.
Most UK homes install a 7kW fast charger as a balance between cost and charging speed.
Breakdown of Installation Costs
The total cost to install a car charger depends on several factors, including the charger type, your home’s electrical setup, and any additional work required. Here’s a typical cost breakdown:
Cost Component | Typical Price Range (GBP) |
Charger Unit | £350 to £1,200 |
Installation Labour | £300 to £1,000 |
Electrical Upgrades | £0 to £1,500+ |
Additional Materials (cables, mounting, etc.) | £50 to £200 |
VAT (20%) | Included in above or extra |
Charger Unit Price
Basic 3kW chargers start around £350.
Popular 7kW models range from £500 to £900.
Smart or premium chargers can cost over £1,000.
Installation Labour
Labour costs vary by region and installer but typically range from £300 to £1,000.
Installation time usually takes 2 to 6 hours depending on complexity.
Electrical Upgrades
Homes with older electrical systems may need upgrades such as a new consumer unit (fuse box) or additional circuits.
If your property lacks a three-phase supply and you want a 22kW charger, costs can increase significantly.
Some homes require trenching or longer cable runs, adding to labour and materials costs.
Government Grants and Incentives
The UK government offers the Electric Vehicle Homecharge Scheme (EVHS), which provides a grant of up to £350 towards the cost of installing a home charger. This can reduce your upfront cost significantly.
To qualify:
You must have off-street parking.
The charger must be installed by an approved installer.
The grant covers up to 75% of the total cost, capped at £350.
Many installers handle the grant application for you, making the process easier.
Factors That Affect Installation Cost
Several factors influence the final price you pay:
Distance from Consumer Unit to Charger Location
Longer cable runs require more materials and labour. If your garage or parking spot is far from your home’s electrical panel, expect higher costs.
Property Type and Age
Older homes may need electrical upgrades to handle the charger’s load safely. Flats or properties without dedicated parking may face additional challenges or restrictions.
Charger Power Rating
Higher power chargers cost more to buy and install. A 22kW charger requires a three-phase supply, which many homes don’t have without costly upgrades.
Installer Choice
Prices vary between installers. It’s wise to get multiple quotes and check reviews to find a reliable and fairly priced professional.
Example Cost Scenarios
Here are some typical examples to give you a clearer idea:
Scenario 1: Basic 3kW charger in a modern home with easy access
Charger: £350
Installation: £300
Electrical upgrades: £0
Total: £650 (before grant)
After £350 grant: £300 out of pocket
Scenario 2: 7kW charger in a suburban home needing minor upgrades
Charger: £700
Installation: £600
Electrical upgrades: £400
Total: £1,700 (before grant)
After £350 grant: £1,350 out of pocket
Scenario 3: 22kW charger in an older home requiring major electrical work
Charger: £1,200
Installation: £1,000
Electrical upgrades: £1,500
Total: £3,700 (before grant)
After £350 grant: £3,350 out of pocket
What to Expect During Installation
The installation process usually follows these steps:
Site Survey: The installer visits your property to assess your electrical system and decide the best charger location.
Quote and Agreement: You receive a detailed quote including all costs and timelines.
Installation Day: The installer fits the charger, runs cables, and makes any necessary electrical upgrades.
Testing and Handover: The system is tested for safety and functionality. You receive instructions on how to use the charger.
Grant Application: The installer submits your claim for the government grant if applicable.
Most installations take one day but can take longer if upgrades are complex.
Tips to Keep Costs Down
Choose a charger with a power rating that matches your needs and home’s electrical capacity.
Install the charger close to your consumer unit to reduce cable length.
Get multiple quotes from certified installers.
Check if your home qualifies for the EVHS grant.
Consider future-proofing by installing a charger that can handle faster charging if you plan to keep your EV long-term.
Maintenance and Running Costs
Once installed, home chargers require minimal maintenance. Occasional checks by a qualified electrician are recommended. Running costs depend on your electricity tariff and how often you charge.
Charging at home is generally cheaper than public chargers. For example, charging a typical EV overnight on a standard tariff might cost around £3 to £5 for a full charge, compared to £10 or more at some public rapid chargers.
Installing a car charger at home is a practical step for EV owners in the UK, offering convenience and cost savings. While prices vary based on your home and charger choice, typical installations range from £650 to over £3,000 before grants. Taking advantage of government incentives and choosing the right charger can help you manage costs effectively. If you’re considering an EV or already own one, getting a home charger installed is a smart investment that supports your transition to cleaner transport.
