London Congestion Charge — What You Need to Know

Many South Africans moving to London confuse ULEZ with the Congestion Charge. They are two completely separate systems, and this confusion costs new arrivals hundreds of pounds in their very first weeks. Understanding the difference - and the payment rules for each - is essential before you drive a single mile in the capital.

ULEZ vs Congestion Charge: two different charges

ULEZ is an emissions tax. It charges you 12.50 pounds per day if your vehicle does not meet minimum emission standards. It applies across the whole of Greater London, 24 hours a day, 7 days a week, 365 days a year. If your car is compliant, you pay nothing.

The Congestion Charge is completely separate. It is a 15 pound daily fee for driving within central London during charging hours, regardless of how clean or new your car is. A brand-new electric vehicle and a twenty-year-old diesel van are both subject to the Congestion Charge if they enter the zone during operating hours (although EVs can apply for a discount - more on that below).

If you drive a non-compliant petrol or diesel car into central London during charging hours, you will owe both charges - 27.50 pounds for a single journey. Drive in and out five days a week for a month, and you are looking at over 500 pounds before you have paid for fuel, insurance, or parking.

How the Congestion Charge actually works

There are no toll booths, no barriers, and no physical signs telling you that you have just been charged 15 pounds. The entire system is camera-based. A network of Automatic Number Plate Recognition (ANPR) cameras positioned at every entry point to the zone reads your registration plate as you drive in. From that moment, you owe the charge.

The zone boundary is marked by large white road signs with a red circle containing a white "C." If you see one, you have entered the zone. But in practice, these signs are easy to miss when you are concentrating on unfamiliar roads, navigating roundabouts for the first time, or following a sat-nav that has routed you straight through the middle of central London without warning.

The charging hours operate seven days a week. Monday to Friday, the charge applies from 7am to 6pm. On weekends, Saturdays, Sundays, and bank holidays, it applies from 12pm to 6pm. There is no free period anymore - the previous overnight and Sunday exemptions were removed in recent years. Christmas Day is the only day the charge does not apply.

The payment deadline and penalty system

This is where most new arrivals get caught. You are expected to pay the Congestion Charge yourself, proactively, by midnight on the third day after your journey. There is no invoice. There is no reminder. There is no text message. The system assumes you know you entered the zone and that you know you need to pay.

If you pay in advance (before midnight on the day of travel) or on the day itself, the charge is 15 pounds. If you pay the next day or the day after, it is still 15 pounds. If you miss the deadline - midnight on the third day after your journey - the charge instantly becomes a Penalty Charge Notice (PCN) of 160 pounds, reduced to 80 pounds if you pay within 14 days.

South Africans who are unfamiliar with the system routinely miss these deadlines. You drive through central London on a Tuesday without realising you have entered the zone. By Saturday, a PCN has been generated. You might not even receive it for a week or two. By then, the 14-day discount window may have already closed, and you owe the full 160 pounds.

If you drive into the zone regularly without paying, the fines compound rapidly. It is entirely possible to accumulate over a thousand pounds in penalties within a single month without even being aware that you owe anything.

Auto Pay: the essential safety net

The single most important thing you can do after buying a car in London is register for TfL Auto Pay. This service links your vehicle registration to a payment card. Every time an ANPR camera detects your car entering the Congestion Charge zone, TfL automatically charges your card - no action required on your part, no deadlines to remember, no risk of penalties.

Registration is free and takes about ten minutes on the TfL website. You will need your vehicle registration number, V5C reference number, and a debit or credit card. Once set up, you will also receive a small discount on the daily charge.

There is no downside to registering, even if you rarely drive into central London. The charge only applies when the cameras detect your car in the zone. If you never enter, you are never charged. But if you accidentally drive through on a day trip without realising, Auto Pay catches it and bills you at the standard rate rather than the 160 pound penalty.

Electric vehicle exemptions (and their limits)

Fully electric vehicles (EVs) are currently eligible for the Cleaner Vehicle Discount, which means zero Congestion Charge. However, this is not automatic. You must register your EV with TfL and apply for the discount before you drive into the zone. If you drive an eligible EV into central London without registering first, you will be charged the full 15 pounds - and if you do not pay on time, you will receive the 160 pound penalty just like everyone else.

Plug-in hybrids (PHEVs) lost their exemption in 2025 and are now subject to the full charge. Standard hybrids were never exempt. If you are buying a car partly to avoid the Congestion Charge, make sure it is a fully battery-electric vehicle and register it with TfL before your first journey into the zone.

Planning your routes

If you live in outer London or the suburbs, you can often avoid the Congestion Charge zone entirely by planning your routes carefully. The zone covers a relatively small area of central London - roughly the area bounded by Euston, the City, Elephant and Castle, and Hyde Park. Most sat-nav systems and Google Maps can be set to avoid toll roads and congestion zones.

For South Africans settling in popular expat areas like Wimbledon, Raynes Park, or the Surrey suburbs, daily driving rarely requires entering central London. But an unexpected appointment in the City, a weekend trip to the West End, or a wrong turn off the South Circular can put you inside the zone before you realise it. Auto Pay is your insurance policy against these accidental entries.
