EV bay marking: sizes, symbols and accessibility rules
As Irish car parks add charging, the marking around each bay does a lot of work: it identifies the bay as EV-only, guides drivers to it, keeps the charging cable route safe, and makes sure at least some bays are usable by wheelchair users. This guide covers how EV bays are marked in practice.
A standard EV charging bay follows normal Irish car-parking dimensions, roughly 2.4 to 2.5 m wide by 4.8 to 5 m long, and is marked with an EV or charging symbol, often over a coloured infill (commonly green) with the letters EV. There is no single Irish law fixing EV bay colours, so the priorities are clear dimensions, a recognisable symbol, safe cable routing, and providing accessible bays with extra transfer space for wheelchair users.
Bay sizes
An EV bay is dimensioned like any other parking bay: about 2.4 to 2.5 m wide and 4.8 to 5 m long is typical for a standard perpendicular bay. Charging adds two practical considerations, leave the charger reachable by the vehicle's charge port (which varies front, rear and side by model), and keep the cable run clear of the pedestrian route. Where space allows, a slightly wider bay makes charging easier for everyone.
Symbols and colour
The bay should carry a clear EV or charging symbol so it reads as charging-only at a glance, usually stencilled in the bay and repeated on signage. A coloured infill makes the bay unmistakable from a distance; green is the most common choice in Ireland, though there is no legal requirement to use a specific colour. The letters EV are often added alongside the symbol.
Because colour is a convention rather than a rule here, the important things are legibility, consistency across the car park, and a durable finish that still reads clearly after a few winters.
Numbering and wayfinding
Numbering each bay helps drivers, payment apps and site management match a car to a charger and a fault to a location. Directional marking and signage to the EV zone reduce circling and keep non-EV drivers out of the bays. Numerical line marking is a service we provide alongside bay marking.
Accessibility
At least some chargers should be usable by a wheelchair user. In practice that means providing accessible bays with additional width or a marked transfer space beside the bay (an accessible bay is wider than a standard one, commonly with around 1.2 m of extra transfer aisle), a firm level surface, and a charger and screen within reach from a seated position. Treat this as good practice guided by SEAI's technical guidance on EV charging and accessibility rather than a fixed EV-specific standard, and design the space so a wheelchair user can get out of the car and reach the charger.
Cable and trip safety
A charging cable crossing a walkway is a trip hazard. Marking should position the bay and its walkway so cables stay within the bay footprint, and pedestrian routes past the bays should be clearly marked and, ideally, physically separated. This is where bay marking connects to wider pedestrian segregation.
Durability outdoors
EV bays live outdoors under weather and constant turning traffic, so the marking has to last. UV Line Marking applies durable coating in any colour, including the green infill and EV symbols, so bays stay legible. See our EV charging bay line marking service.
Frequently asked questions
-
What size should an EV charging bay be?
About 2.4 to 2.5 m wide by 4.8 to 5 m long is typical for a standard bay, the same as a normal parking space. The key extra is leaving the charge port reachable and keeping the cable clear of the walkway; a little extra width helps. -
Do EV bays have to be green in Ireland?
No. There is no legal requirement to use a specific colour for EV bays in Ireland. Green infill is the most common convention because it is instantly recognisable, but the priorities are a clear symbol, good legibility and consistency. -
How should accessible EV bays be marked?
Provide wider bays or a marked transfer space beside the bay so a wheelchair user can get out and reach the charger, on a firm level surface, following Building Regulations accessibility principles. There is no single EV-specific dimension in law, so design for genuine usability.
