Electric vehicles are truly hitting their stride across the UK. If you’ve kept an eye on the latest data from the Society of Motor Manufacturers and Traders, you will know that roughly one in six new cars hitting our roads is now fully electric. This shift is only going to accelerate as we head toward the 2030 milestone, which is the point where the government plans to end the sale of new petrol and diesel models.
If you’ve been out and about lately, you might have spotted cars sporting a distinctive green strip on their registration plates. These are known as green number plates, and if you are an EV owner or considering making the switch, here is everything you need to know about how they work and why they actually matter.
What Do They Actually Look Like?
Despite the name, these aren’t bright green slabs of plastic. To keep things legal and legible for cameras, the plates remain the standard white at the front and yellow at the rear. The “green” part refers to a vertical green flash or block on the left hand side of the plate. This sits exactly where you would usually find the blue UK or GB identifier. It is a subtle but clear signal to everyone else on the road that your car produces zero tailpipe emissions.
The Logic Behind the Green Flash
You might be wondering if this is just a bit of a gimmick, but there is some genuine utility behind it. The primary goal is to make zero emission vehicles easily identifiable at a glance. By raising the profile of EVs, the government hopes to normalise electric driving and encourage more people to ditch the fuel pump.
Beyond just looking the part, these plates serve a functional purpose for local councils. They make it much easier for authorities to identify electric cars for specific perks. In the future, we could see more councils offering incentives such as cheaper or free parking, or even exemptions from certain tolls and low emission zones. Having that green flash makes it simple for a traffic warden or a camera system to see that you’re eligible for those benefits.
Can You Fit Them to Your Car?
These plates officially entered circulation on December 8, 2020. The good news is that they aren’t just reserved for brand new registrations. If you have an electric car that is a few years old, you are perfectly entitled to retro-fit a set of green plates to it.
However, there is one very important rule to keep in mind. These plates are strictly for zero emission vehicles only. This means full battery electric cars (BEVs) or hydrogen fuel cell vehicles. Even if you drive a plug in hybrid that can do a decent range on battery power alone, you aren’t allowed to use a green plate because your car still has an internal combustion engine tucked away under the bonnet.
If you are not sure whether your car is an electric vehicle, you can carry out a car check. This will confirm if the vehicle is electric and will also go one step further by revealing its full history, such as whether it has been written off previously or has outstanding finance against it.
How to Get Your Hands on a Set
If you are currently in the process of buying a new EV, most dealerships will ask if you’d like the green plates fitted as standard. If they don’t bring it up, just give them a nudge and they’ll usually sort it for you.
For those who already own an EV and want to upgrade their current plates, it is a straightforward process. You can head to any registered number plate supplier, such as Halfords or a local motor factor. Just remember to bring your V5C logbook and some ID with you to ensure everything is above board and meets the legal standards for UK roads.
