The congestion charge system, which has regulated traffic in central London since 2003, has undergone its most significant revision in two decades. The updated framework introduces a graduated discount scheme that preserves incentives for zero-emission vehicles while addressing the practical demands of increased EV adoption.
Under the new system, standard vehicles pay £18 per day to enter the zone between 7am and 6pm on weekdays, and between noon and 6pm on weekends and bank holidays. Electric vehicles, previously fully exempt, now benefit from a tiered Auto Pay discount system that keeps daily charges lower than those for petrol or diesel vehicles.
The new framework demonstrates how policy evolves alongside technological adoption, balancing environmental objectives with operational requirements as the automotive landscape transforms.
Graduated Incentives for Electric Vehicles
The revised framework differentiates charges by vehicle type. Electric cars registered for Auto Pay receive a 25% reduction, reducing the daily fee to £13.50, while electric vans, heavy goods vehicles, and quadricycles benefit from a 50% discount. These rates will adjust from March 2030, when electric cars will receive a 12.5% discount, and larger EVs a 25% reduction. This staged approach gives businesses and residents clarity for planning their vehicle strategies.
The system maintains substantial cost advantages for zero-emission vehicles compared to conventional alternatives, while generating revenue to support London’s transport network and encouraging shifts toward public transport and active travel.
Protected Provisions for Existing Residents
Current beneficiaries of the residents’ discount are unaffected, retaining their 90% reduction regardless of vehicle type. Those who apply after March 1, 2027, will see the 90% discount applied only to electric vehicles, ensuring long-term incentives remain focused on zero-emission transport. The dual-track system recognises the differing circumstances of current and future residents while supporting the scheme’s broader objectives.
Applications submitted after this date will see the 90% discount applied exclusively to electric vehicles. The dual-track approach acknowledges the financial and practical considerations of existing residents whilst directing future incentives towards zero-emission transport.
The policy recognises that residents within the congestion zone face different circumstances to those passing through, with the discount structure designed to support those who live in the area whilst maintaining the scheme’s broader objectives.
Response to Adoption Patterns
Since the cleaner vehicle discount launched in 2019, EV registrations within the congestion zone have risen nearly sixfold, from approximately 20,000 to more than 116,000 earlier this year. By the end of 2026, EVs are projected to account for nearly 20% of all vehicles in the zone.
Transport for London estimates that without the revised framework, weekday traffic could increase by more than 2,000 vehicles, demonstrating the importance of balancing incentives with congestion management.
Sustainable Urban Mobility
The revised congestion charge reflects wider questions about sustainable urban transport funding as vehicle fleets electrify. Cities worldwide face similar challenges in maintaining revenue streams that support public transport and infrastructure whilst encouraging the shift away from fossil fuel vehicles.
London’s framework offers a clear example of how multiple objectives can be aligned. Electric vehicles continue to benefit from meaningful financial advantages, while all road users contribute to congestion management and the upkeep of the capital’s transport network. The extended timeline for discount adjustments provides both residents and businesses with certainty for long-term planning.
The structure illustrates how environmental policy can adapt alongside technological change, maintaining incentives for cleaner transport while addressing the practical realities of widespread adoption. As EVs become increasingly common, the updated system ensures the congestion charge continues to fulfil its dual role: managing traffic volumes effectively and supporting London’s broader transport infrastructu
