Choosing the right EV charger can feel overwhelming, but at Sustainable Electrical Services, we’re here to simplify the process. Whether you’re a first-time EV owner or upgrading your current setup, this guide covers the key factors to consider when choosing an EV charger for your home charging solution. Let’s dive in!
1. EV Charging Speed
One of the most important factors to consider is the speed of the EV charger. For most UK homes, a 7kW charger is ideal. It’s over twice as fast as a standard 3kW unit, charging most EVs in approximately 6-8 hours. This speed is perfect for overnight charging and integrates seamlessly with the single-phase electrical systems common in UK residences.
If your property has a three-phase electrical supply, you may opt for a 22kW charger. This offers significantly faster charging and can help with load balancing your electrical system.
2. Tethered vs Untethered
Tethered EV Chargers:
- Include a built-in cable and plug for convenience.
- Typically come with a 5-metre cable (extendable to 10 metres on certain models at an additional cost).
- Usually have a Type 2 connector, the UK standard.
- Keep in mind: If the cable gets damaged, repairs can be costly as the entire charger may need replacing.
Untethered EV Chargers:
- Allow you to use your own cable, which can be safely stored in a garage or car boot.
- Offer flexibility with cable length and can reach multiple vehicles parked on a driveway.
- Damaged cables are easy to replace without specialist electrical assistance.
3. EV Cable Length
Ensure the cable length of your EV charger is adequate to reach your vehicle comfortably without causing strain or trip hazards. While most tethered chargers come with a 5-metre cable, longer options are available. If you opt for an untethered EV charger, you can choose a cable length that suits your parking arrangement.
4. Placement and Size
Proper placement of your charger is crucial. Compact chargers are perfect for small spaces, while larger units may require more room. Assess your home’s layout and parking setup to determine the best location. EV chargers also come in various sizes and colours, from sleek black to clean white, allowing you to match your home’s aesthetic.
5. Solar Integration
If you have solar panels, consider a charger with solar integration features. These EV chargers enable your vehicle to charge directly from surplus renewable energy, maximising efficiency and reducing costs. This is an excellent option for environmentally-conscious homeowners looking to optimise their solar power usage.
6. Safety Features
Safety should be a top priority. Depending on your current electrical installation, you’ll need an EV charger that complies with UK IET regulations and current British Standards. Key considerations include:
- Surge protection
- RCD protection
- O-PEN protection

7. Warranty
Check the warranty period for your chosen EV charger. Most models offer warranties ranging from 1 to 3 years, with some premium brands extending up to 7 years. A longer warranty provides peace of mind and covers potential issues over time. Some manufacturers also offer extended warranty options, so be sure to explore these.
Why Invest in EV Charging?
The rise of electric vehicles marks a significant step toward a more sustainable future. Home EV charging enhances convenience, reduces your environmental footprint, and lowers costs compared to public charging stations. It’s an investment that pays off in both the short and long term.
