Which EV Charger

As more households across the UK make the switch to electric vehicles, one of the biggest decisions drivers face is which EV charger to install at home. While all chargers perform the same essential function, there are significant differences in speed, features, and cost. Choosing the right charger ensures not only safe and efficient charging but also long term convenience and value. Understanding the main types of chargers and what to consider before installation can help you make the best decision for your home and lifestyle.

The Main Types of EV Chargers

EV chargers are categorised by the amount of power they can deliver, which directly affects how quickly your car will charge. The most common options for UK homes are 3kW, 7kW, and 22kW chargers.

A 3kW charger, sometimes referred to as a slow charger, uses a standard three pin socket. This is the least efficient method, taking many hours to charge a typical electric vehicle fully. While suitable for occasional use or as a backup, it is not recommended as a permanent solution due to safety concerns and the risk of overloading circuits.

The 7kW charger is the most popular choice for UK homeowners. It provides a much faster charging time compared to a three pin socket, with most cars able to achieve a full charge overnight. These chargers are wall mounted, designed specifically for EV use, and are the standard offering in most professional installations.

A 22kW charger is classed as a fast charger but is only compatible with properties that have a three phase electrical supply. Most homes in the UK only have single phase supply, meaning a 22kW charger is not an option without significant and costly upgrades. These are more common in commercial premises or very large properties.

Smart Chargers Versus Standard Models

When deciding which EV charger to install, another consideration is whether to choose a standard model or a smart charger. A standard 7kW charger will do the job effectively, but smart chargers add extra features such as Wi-Fi connectivity, mobile app control, charging schedules, and energy monitoring.

One of the key benefits of a smart charger is the ability to set charging times to take advantage of cheaper off peak electricity tariffs. This can result in significant savings over the course of a year. Some smart chargers can also integrate with solar panels or home battery storage, allowing homeowners to use renewable energy more efficiently.

Although smart chargers are more expensive upfront, their added convenience and energy saving potential often make them a worthwhile investment for households with long term EV plans.

Safety and Compliance

Regardless of which charger you choose, safety must be the priority. UK law requires that EV chargers are installed in line with Part P of the Building Regulations and BS7671 wiring regulations. The installation must be carried out by a qualified electrician who is experienced in fitting EV charging equipment. Modern chargers are fitted with built in safety features such as residual current protection and load management to prevent overloading the household supply.

It is also important to choose a charger that meets the latest government standards. Regulations now require most home EV chargers to have smart functionality, allowing them to communicate with the grid and manage energy demand more effectively. This ensures your installation remains compliant with future requirements and avoids the risk of needing an upgrade sooner than expected.

Cost Considerations

The cost of an EV charger varies depending on the model and installation requirements. A standard 7kW charger typically costs between £800 and £1,200 including installation. Smart chargers are at the higher end of this range, sometimes exceeding £1,500 if additional work is needed, such as upgrading the consumer unit or running long cable routes.

Although the initial investment may seem high, the convenience and reliability of having a dedicated home charger quickly pays off compared to relying on public charging points. For those on specific energy tariffs, the savings from off peak charging can also offset the higher upfront cost of a smart charger.

Future Proofing Your Installation

When deciding which EV charger to install, it is worth considering your long term plans. If you intend to purchase a second electric vehicle in the future, choosing a charger with load balancing or dual charging capability can save money later on. Similarly, if you are planning to install solar panels, selecting a charger that can integrate with renewable energy systems is a smart move.

Technology in the EV sector is advancing quickly, so opting for a model that supports updates and additional features can extend its lifespan. Many smart chargers now receive software updates via Wi-Fi, ensuring they remain compatible with new vehicles and evolving energy regulations.

Final Thoughts

For most UK households, a 7kW smart charger is the best balance of speed, safety, and functionality. While basic chargers may cost less, the long term benefits of energy savings, convenience, and future proofing make smart models the preferred choice. Whatever option you select, ensure it is installed by a qualified electrician and certified to UK standards. With the right charger in place, you can enjoy faster, safer, and more efficient charging at home, giving you peace of mind every time you plug in your vehicle.
