If you drive an electric car into central London, 2026 changed the sums. EVs are still cheaper than petrol or diesel cars in plenty of ways, but the old 100% Cleaner Vehicle Discount for the Congestion Charge has ended.
The practical result is simple: electric cars can now pay £13.50 per charging day if they are registered for Auto Pay, or the full £18 if they are not. Electric vans, HGVs and quadricycles can get a bigger discount, but again only when the vehicle is on Auto Pay.
For occasional London trips, that may be an annoying extra line on the budget. For business drivers, volunteers, trades, sales teams and anyone claiming mileage or expenses, it is more than that. It is a new trip cost that needs to sit next to your mileage log, not float around in a card statement waiting to ambush you later.
What changed for EV drivers?
Transport for London says the Congestion Charge is now £18 if paid on the day of travel or in advance, and £21 if paid within three days after travel.
The charge applies when you drive within the Congestion Charging Zone during charging times:
- 07:00 to 18:00, Monday to Friday
- 12:00 to 18:00, Saturday, Sunday and bank holidays
- No charge from Christmas Day to the New Year's Day bank holiday, inclusive
The previous full Cleaner Vehicle Discount has ended. In its place, TfL has introduced a tiered discount for electric vehicles registered for Auto Pay:
- Electric cars: 25% discount, so £13.50 instead of £18
- Electric vans, HGVs and quadricycles: 50% discount, so £9 instead of £18
The important detail is Auto Pay. TfL says the discounted charge is only available for eligible electric vehicles registered for Auto Pay. If the vehicle is not on Auto Pay, the discounted rate will not apply.
Why the change matters for mileage tracking
The Congestion Charge is not charged per mile. It is a daily zone charge. That means it can make short journeys look surprisingly expensive on a cost-per-mile basis.
Imagine two EV business journeys into the zone:
- a 10-mile round trip with a £13.50 EV car charge works out at £1.35 per mile before electricity
- a 60-mile round trip with the same £13.50 charge works out at 22.5p per mile before electricity
The charge is identical, but the trip economics are completely different. That is why it helps to log the zone charge against the actual journey, not just as a general motoring expense.
If you only record mileage, you miss the fixed trip cost. If you only keep the TfL payment receipt, you lose the journey context. Put the two together and you get a much clearer picture of what the drive actually cost.
What EV drivers should record
For personal budgeting, a simple note is enough. For business mileage or expenses, be more deliberate. A clean record should include:
- date of travel
- journey purpose, especially if it was a work trip
- start and end locations, or enough detail to identify the route
- business miles and personal miles, if the day includes both
- whether the Congestion Charge applied
- amount paid, for example £13.50, £9, £18 or £21
- vehicle type, especially if you use both cars and vans
- payment method or receipt reference
That last point is dull but useful. When your bank statement shows a road-user charging payment weeks later, a receipt reference linked to a mileage entry saves a lot of archaeological digging. Nobody wants to be Indiana Jones and the Temple of Forgotten Expense Claims.
Auto Pay is now part of the cost calculation
Auto Pay used to be mostly about convenience. For EVs in the Congestion Charging Zone, it now affects the price.
If an electric car qualifies and is correctly registered on Auto Pay, the daily charge is £13.50. If the same car is not registered for Auto Pay, the driver can pay £18 instead. That is an extra £4.50 per charging day, or £45 over ten chargeable trips.
For an electric van, the difference can be larger. The Auto Pay discounted charge is £9, compared with £18 without the discount. If a small business van enters the zone frequently, getting the setup right is not admin theatre; it is real money.
TfL says UK-registered vehicles need a London Road User Charging account, Auto Pay set up, and the vehicle added to the Auto Pay service. If the vehicle details are already correct on Auto Pay, the EV discount should be applied automatically.
Do EVs still avoid ULEZ?
Yes, the Congestion Charge and ULEZ are separate schemes with different aims. The Congestion Charge is about managing traffic in central London. ULEZ is about emissions.
A pure EV still has no tailpipe emissions, but it still takes up road space. That distinction explains why an EV can avoid ULEZ charges and still pay a Congestion Charge on the same day.
For record keeping, separate the two. Do not label everything as "London charge" and hope future-you understands it. Track:
- Congestion Charge: daily central London zone cost
- ULEZ: emissions-based charge, usually not applicable to fully electric cars
- parking: separate again, often the sneakiest cost of the lot
- charging: electricity cost, ideally linked to the trip if it was a work journey
What happens in 2030?
TfL has already signposted a future reduction in the EV discounts. From 4 March 2030, the discount is due to reduce to:
- 12.5% for electric cars on Auto Pay
- 25% for electric vans, HGVs and quadricycles on Auto Pay
That is not an immediate 2026 budgeting problem, but it is worth knowing if you are choosing a company car, electric van, salary sacrifice vehicle, or delivery setup that will still be in use in a few years.
In other words: do not build your London driving budget around the idea that EV zone discounts will stay generous forever. They are now part of a tapering system.
A simple way to add this to your mileage routine
The best setup is boring, which is exactly what you want from expense admin.
- Log the journey first: date, purpose, route and miles.
- Add a zone-charge field: Congestion Charge yes/no, then amount paid.
- Attach or reference the receipt: TfL payment, Auto Pay statement or account reference.
- Split personal and business use: if only part of the day was business, make that clear.
- Review monthly: repeated zone charges can change whether driving, train travel, car club use or route changes make more sense.
This matters even if your employer reimburses costs separately from mileage. A single journey can now have mileage, charging, parking and zone-charge components. If those sit in four different places, mistakes are easy. If they sit next to one journey entry, the claim is much easier to explain.
The bottom line
The 2026 Congestion Charge change does not make EVs a bad choice for London drivers. It does make the cost picture less "EV equals free access" than it used to be.
For EV cars, the key number is usually £13.50 per chargeable day with Auto Pay. For eligible electric vans and larger vehicles, it can be £9 with Auto Pay. Without the right Auto Pay setup, the discount can disappear.
If you drive into central London for work, charity shifts, client visits, deliveries or site calls, treat the Congestion Charge as a journey cost. Log it beside the mileage. That one small habit gives you a cleaner cost-per-mile view, easier expense claims, and fewer "what was this payment for?" moments later.
