Why London's scheme is not a simple template
London's congestion charge, and later the Ultra Low Emission Zone (ULEZ), are frequently cited as proof of concept for road pricing schemes elsewhere in the UK, and the London evidence genuinely does show reduced traffic and improved air quality within the charging zone. But London's scheme did not succeed in isolation — it succeeded alongside one of the densest, most frequent public transport networks in the world, where the Underground, buses and, more recently, the Elizabeth line offer a genuine, time-competitive alternative to driving for the overwhelming majority of journeys within the zone. Treating the charge itself, separate from that alternative, as the transferable lesson misreads why it worked.
The public transport gap in most other UK cities
Outside London, and to a lesser extent a handful of other major cities, UK public transport provision drops off sharply — bus frequency in many towns and smaller cities has been cut significantly over the past decade and a half, and few places outside London have anything resembling a comprehensive rail or light rail network reaching most residential areas. Introducing a charge for driving into a city centre where public transport genuinely cannot get most residents to work reliably does not function as a nudge toward a viable alternative; it functions as a straightforward tax on people who have no realistic alternative to using their car.
Who actually bears the cost
This distinction matters most for who ends up paying. In a city with strong public transport, a congestion charge primarily affects people who are choosing to drive despite having a workable alternative — arguably a reasonable behaviour-change lever. In a city without that alternative, the charge falls hardest on people who need to drive regardless, and lower-income drivers with older, more polluting vehicles (who are least able to afford a compliant newer car) are disproportionately exposed, precisely the group least able to absorb an additional daily cost. This is not a hypothetical concern — it was one of the most consistent criticisms raised during the expansion of London's own ULEZ into outer boroughs with weaker transport links than the original central zone.
What proper sequencing would look like
None of this is an argument against road pricing or emission zones in principle — traffic congestion and air pollution are real problems with real costs, including to public health, that most UK cities genuinely need to address. The argument is about sequencing: a charging scheme introduced after meaningful investment in bus frequency, reliability and affordability in the same city gives residents a genuine choice before asking them to pay for the option they are not taking. A scheme introduced before that investment, on the promise that the charge revenue will eventually fund it, asks people to bear a cost now for a benefit that may or may not fully materialise on the promised timeline.
The political cost of getting the order wrong
Getting the sequencing wrong has a genuine political cost too, and not a trivial one — several UK councils that have explored or introduced charging schemes without first demonstrating a credible public transport alternative have faced sustained local opposition that has, in some cases, forced scaled-back or abandoned plans, setting back the case for road pricing as a policy tool more broadly. A scheme that is fair, and seen to be fair, because it follows genuine investment rather than preceding it, is far more likely to survive the inevitable local backlash than one that asks residents to trust a promise about future transport improvements that has not yet been delivered.
What a genuinely fair rollout would look like in practice
None of the argument above should be read as opposition to improving urban transport and air quality — the opposite is true. The point is that the sequencing and design of any scheme matters enormously to whether it is experienced as fair. A genuinely well-sequenced rollout would typically involve several stages: first, a meaningful and independently verified uplift in bus frequency and reliability across the specific charging zone and its surrounding catchment, ideally sustained for long enough that residents can genuinely observe and trust the improvement rather than being asked to take it on faith; second, a scrappage or upgrade support scheme specifically targeted at lower-income drivers with older, non-compliant vehicles, funded in advance rather than promised as a future use of charge revenue; and only then, third, the introduction of the charge itself, ideally phased in with a reduced or waived rate for an initial adjustment period.
Manchester's Clean Air Zone plan, ultimately paused and substantially reworked after significant local and business opposition specifically over its initial approach to smaller businesses and lower-income drivers, is a useful cautionary case study in how getting this sequencing wrong can set back the underlying policy goal for years, not just delay a single scheme. A scheme reworked and reintroduced after public trust has already been damaged faces a considerably harder path to acceptance than one designed with this sequencing built in from the outset, which is precisely why the argument here is about design and order, not about abandoning the underlying goal of reducing urban traffic and improving air quality that congestion charging schemes are ultimately meant to serve. A council genuinely committed to both fairness and effectiveness has every reason to publish its transport investment sequencing alongside any charging proposal, allowing residents to judge the credibility of the plan for themselves rather than being asked to accept it on trust alone.
