Green Flash Number Plates: Who Can Have Them?

Green flash number plates, the short answer: only zero-emission vehicles can legally have one. Since 8 December 2020, cars, vans, motorbikes and other vehicles that produce no CO2 at the tailpipe have been allowed to show a green flash on the left-hand side of their number plates. That means fully electric (and hydrogen) vehicles qualify. Hybrids, including plug-in hybrids, don’t, because they still have an exhaust. The green flash is optional, even on an electric car.

Who can have a green flash

The rule is about the tailpipe. The government’s announcement said green plates can go on any vehicle, including cars, vans, buses, HGVs, taxis and motorcycles, as long as it emits no CO2 at the tailpipe. The DVLA’s leaflet INF104 calls them eligible zero emission vehicles (ZEVs).

Vehicle	Green flash allowed?
Fully electric (battery EV)	Yes
Hydrogen fuel cell	Yes
Plug-in hybrid (PHEV)	No
Self-charging / mild hybrid	No
Petrol or diesel	No

It works for existing cars too. If you’ve had an electric car since before December 2020, you can swap to green flash plates now.

“Can I have one on my hybrid?”

Hybrid owners ask us about the green flash all the time, and it’s easy to see why: the car is partly electric, it might charge from a plug, and the green flash looks good.

But the rules don’t have a middle ground. A hybrid still burns fuel and has a tailpipe, so it isn’t a zero-emission vehicle, and a green flash on it means the plate doesn’t meet the rules. That puts it in the same position as any other incorrectly displayed plate, which can mean a fine of up to £1,000 and an MOT fail.

Demand for green flash plates has grown since we launched our EV range in September 2026.

Where the flash goes and what it looks like

Position: a vertical green band on the left-hand side of the plate, front and rear.
Optional: no electric car has to show one.
Everything else stays the same: the plate still needs the standard font, spacing, reflective background, supplier’s name and BS AU 145e mark.

The flash doesn’t change any other rule, so our guides to number plate spacing and number plate sizes still apply.
