As more drivers switch to electric, public charging points are getting busier. Unlike petrol stations where you fill up in five minutes and leave, EV charging can take anywhere from 20 minutes to several hours — which means shared chargers require a level of consideration that never existed at the pump.
Most of the rules below are not written on any sign. They are community norms that experienced EV drivers follow to keep things running smoothly for everyone. If you are new to EV ownership, learning these early will save you from awkward encounters and unnecessary fees.
1. Don’t Charge Past 80% on Rapid Chargers
This is the golden rule of public rapid charging. When your EV's battery reaches approximately 80%, the charging speed drops dramatically. A charger that was delivering 100kW at 30% might slow to 20–30kW above 80%. This means the last 20% can take as long as the first 70%.
While you are sitting at 85% watching the speed crawl, someone else might be waiting at 10% — desperate for the charge you are slowly accumulating. By stopping at 80%, you get the vast majority of your range in the fastest time, and you free up the charger for the next person.
| State of Charge | Typical Rapid Charge Speed | Time for Each 20% |
|---|---|---|
| 10% → 30% | 80–100kW | ~10 minutes |
| 30% → 50% | 70–90kW | ~12 minutes |
| 50% → 70% | 50–70kW | ~15 minutes |
| 70% → 80% | 30–50kW | ~10 minutes |
| 80% → 100% | 10–25kW | ~30–45 minutes |
2. Move Your Car When Charging Is Complete
A charging bay is not a parking space. Once your car has finished charging, move it promptly so the next person can use the charger. This applies especially to rapid chargers at service stations where demand is highest.
Many networks now enforce this with overstay fees. If you leave your car plugged in after charging completes, you could be charged £0.10–£0.50 per minute. On a 30-minute overstay, that is £3–£15 in unnecessary fees.
- Set a timer on your phone for when charging will roughly complete
- Most charging apps send a notification when your session ends — enable these
- If you need to leave the car (for example, at a restaurant), estimate your charging time and come back promptly
3. Queue Fairly: First Come, First Served
When all chargers are occupied, the accepted practice is simple: first come, first served. Park nearby, stay visible, and wait your turn.
- Do not reserve a charger by placing cones, bags, or other objects in the bay
- Do not park across multiple bays to discourage others from queuing
- Be visible. If you are waiting, park where the current user can see you. This encourages them to move promptly when done
- Communicate. If there are multiple people waiting, a quick conversation to confirm the queue order avoids confusion
- Use apps to check availability. Before driving to a charger, check Zap-Map for real-time status. No point queuing if there is a free charger five minutes down the road
Some busy charging locations (like Tesla Supercharger sites and Gridserve Electric Forecourts) have designated waiting areas. Use them rather than hovering directly behind someone's car.
4. Never Unplug Someone Else’s Car
This should go without saying, but: never unplug another person's charging cable, even if their car appears to have finished charging. There are several reasons.
- Most EVs lock the cable while connected. You physically cannot remove it without the owner unlocking it via their key or app
- The car may still be conditioning its battery. Some EVs continue to draw a small amount of power after the main charge for battery health purposes
- It is disrespectful and could cause damage. Forcibly removing a locked cable can damage the connector
- It could be considered interference with property. Tampering with someone's vehicle is never acceptable
If someone has left their car on a charger long after finishing, you can leave a polite note or report the situation to the charging network's customer service.

5. Rapid Chargers Are for Long Journeys, Not Daily Top-Ups
Rapid and ultra-rapid chargers (50kW+) are expensive, high-demand resources designed primarily for long-distance travel. If you are just topping up for your daily commute, use a slow or fast charger instead.
- Slow chargers (3–7kW) are ideal for overnight or all-day parking — supermarkets, workplaces, car parks
- Fast chargers (7–22kW) are good for 1–3 hour stops — shopping centres, gyms, town centres
- Rapid chargers (50kW+) should be reserved for when you genuinely need a quick boost on a long journey
Using a rapid charger for a 30-minute daily top-up when there is a free slow charger at Tesco nearby is both wasteful and inconsiderate. You are using an expensive resource unnecessarily while someone on a long journey may genuinely need it.
6. Report Broken Chargers
Broken chargers are one of the biggest frustrations in the UK EV charging experience. If you find a charger that is not working, take 30 seconds to report it. This helps the network fix it faster and saves other drivers a wasted journey.
- Zap-Map — Update the charger's status to "out of order" and leave a comment describing the issue
- Network app — Most network apps have a "report a fault" button. Use it. The network may not know about the problem until someone reports it
- Phone the number on the charger — Most chargers display a helpline number. A quick call can sometimes get a remote reset that fixes the issue immediately
The more people who report faults, the faster they get fixed, and the better the experience becomes for everyone.
7. Be Mindful of Overstay Fees
Overstay fees are becoming standard across UK charging networks. They exist for good reason — to discourage people from using chargers as parking spaces. Here is what to expect.
| Network | Overstay Fee | Grace Period |
|---|---|---|
| BP Pulse (rapid) | £0.10/min | 10 minutes after charge completes |
| Tesla Supercharger | £0.50/min (busy) / £0.25/min (not busy) | 5 minutes |
| Gridserve | £0.15/min | After 90-minute max session |
| InstaVolt | £0.25/min | After 60-minute max session |
| Ionity | £0.20/min | 10 minutes after charge completes |
Fees and policies change regularly. Check the current terms in your network app.
A 30-minute overstay at a Tesla Supercharger during peak times costs £15 — potentially more than the charge itself. Set reminders, enable app notifications, and treat the grace period as a maximum, not a target.
8. ICEing: What to Do When Petrol Cars Block Charging Bays
ICEing — when an Internal Combustion Engine (ICE) vehicle parks in an EV charging bay — is one of the most frustrating experiences for EV drivers. It is especially common at supermarkets and car parks where charging bays may not be well-marked or enforced.
What to do if you encounter ICEing:
- Do not leave a confrontational note. It rarely helps and can escalate the situation
- Report it to the car park operator or property manager. Many now issue fines for non-EVs in charging bays
- Take a photo and report to the charging network if it is a persistent issue at that location
- If it is a council-owned car park, report to your local council. Some issue fixed penalty notices for charging bay misuse
- Use Zap-Map to note the issue in the comments. This warns other EV drivers and creates a record of problem locations
Enforcement is improving. More car parks are installing ANPR cameras and clear signage at charging bays. The situation has improved significantly over the past few years, but it remains an issue in some areas.
- Stop at 80% on rapid chargers — The last 20% takes as long as the first 70%
- Move your car within 5 minutes of charge completing — A charging bay is not a parking space
- Queue fairly — First come, first served. No reserving with cones
- Never unplug someone else’s car — Ever
- Use the right charger for the job — Slow for routine, rapid for long journeys
- Report broken chargers — Takes 30 seconds, helps everyone
- Watch for overstay fees — Set a timer or enable app notifications
- Report ICEing calmly — To the car park operator, not on the windshield
Final Thoughts
EV charging etiquette boils down to one principle: be considerate. The charging network is a shared resource, and the more people who follow these unwritten rules, the better the experience is for everyone.
As the UK's charging infrastructure continues to grow and improve, many of these frustrations will diminish. More chargers mean less competition, less queuing, and less conflict. But until then, following these guidelines marks you out as a thoughtful member of the EV community — and saves you from overstay fees and awkward encounters.
Overstay fees and network policies quoted are based on publicly available information as of April 2026 and may change. Always check the current terms in your charging network app.
