There are several incentives currently available for electric vehicle drivers relating to vehicle excise duty (VED), benefits-in-kind tax (BiK) for home charging installations, parking, and travel. At present, electric vehicles are pay nil road tax but this exemption is scheduled to change from April 2025 (you'll still need to tax the vehicle).
If you rent or own a flat, you could get a grant to install an electric vehicle charging point. Before deciding to purchase an electric vehicle, it's worth finding out what incentives are available for your chosen model as these can vary depending on how you fund the car and where you live and drive.
