Drivers Face Price Hikes in London's Blackwall and Silvertown Tunnels

A New Cost of Crossing the Thames

For decades, driving through the Blackwall Tunnel cost nothing but time, and usually a great deal of it, thanks to the queues that have made this stretch of the A102 one of the most notorious pinch points in London. That changed in 2025 when Transport for London introduced charging across both the historic Blackwall Tunnel and its new neighbour, the Silvertown Tunnel. Now, just months after drivers adjusted to paying for a crossing that used to be free, another price rise is on the way. From September, regular commuters will find themselves roughly £2 a week worse off, according to Auto Express. It's a modest-sounding figure on its own, but it's the direction of travel that matters here, and it tells us a lot about how London intends to manage its roads in the years ahead.

What's Actually Happening

The charge increase applies to both the Blackwall Tunnel and the Silvertown Tunnel, the two parallel crossings linking Greenwich Peninsula in the south with Silvertown and the Isle of Dogs in the north. The Silvertown Tunnel opened in 2025 specifically to relieve pressure on the ageing Blackwall crossing, which has suffered from chronic congestion for years, partly because its Victorian-era northbound bore is too low and narrow for larger vehicles and buses. Rather than leave Blackwall free while charging only for the new tunnel, TfL brought in a joint user charging scheme covering both crossings from the moment Silvertown opened, ending Blackwall's long run as a free river crossing.

The charges are structured with different rates depending on the time of day, with peak-hour trips typically costing more than off-peak or overnight journeys, and with a discount scheme in place for residents of the boroughs closest to the tunnels. From September, TfL is adjusting these rates upward, and for someone making the crossing on a regular commuting pattern, Auto Express reports that works out to an additional £2 a week. Multiply that across the working year and it becomes a noticeable dent in the household budget for anyone who relies on these tunnels to get to work, particularly those in Greenwich, Newham and Tower Hamlets whose daily routines were built around a free crossing that no longer exists.

Why This Matters Beyond the Tunnels

It's tempting to see this as a small, localised story, but it fits a much bigger pattern. London has been steadily expanding the list of roads and zones where drivers pay to travel, from the congestion charge in the centre to the Ultra Low Emission Zone across almost the whole of Greater London, and now user charging on specific river crossings. Each scheme has its own justification, whether that's cutting emissions, funding infrastructure, or managing demand on overstretched roads, but the cumulative effect for many drivers is a steadily rising cost of simply getting from A to B by car.

The Blackwall and Silvertown charges are also a reminder that new road infrastructure in London increasingly comes with strings attached. Building the Silvertown Tunnel wasn't cheap, and TfL has been open that charging is part of how the project pays for itself while also discouraging the kind of induced demand that can quickly clog up a brand new road. East London has historically been underserved by river crossings compared with the rest of the capital, with drivers squeezed between the Rotherhithe Tunnel, Blackwall, and the Dartford Crossing miles further east. Silvertown was meant to ease that bottleneck, particularly for larger vehicles and buses that couldn't fit through Blackwall's low, narrow bore. But easing congestion by adding capacity only works if the pricing doesn't simply push traffic back onto already stretched local roads, which is presumably part of the thinking behind variable, time-of-day pricing rather than a flat fee.

For commuters and small businesses in the area, though, the practical reality is simpler: a crossing that was free is now not just charged, but getting more expensive. That's a real, ongoing cost that needs to be factored into commuting decisions, much as Londoners have had to do with the congestion charge's rise to £18 and its evolving rules for different vehicle types.

The Legal Angle: How Tunnel Charging Actually Works

Road user charging schemes like this one aren't invented on a whim. TfL's power to charge for use of specific roads and crossings comes from the same broad legislative framework that underpins the congestion charge, principally the Greater London Authority Act 1999, which gives TfL and London boroughs the ability to introduce road user charging schemes subject to statutory processes, consultation, and scheme orders setting out exactly how the charge operates.

Enforcement typically relies on Automatic Number Plate Recognition cameras that read vehicle registrations as they pass through the tunnels, matching them against payment records. If a driver hasn't paid within the required window, TfL can issue a Penalty Charge Notice, similar in principle to the enforcement model used for the congestion charge and the ULEZ. These are civil penalties rather than criminal matters, and drivers who believe a PCN has been issued incorrectly, perhaps because payment was made but not correctly recorded, or because a vehicle qualifies for a discount or exemption that wasn't applied, have the right to challenge it. That usually starts with an informal or formal representation to TfL, and if unsuccessful, can proceed to an independent tribunal.

It's worth being clear that this is a different legal animal from a typical parking PCN issued under the Traffic Management Act 2004 for something like an overstay or a resident permit dispute. Tunnel user charges sit under their own scheme rules, though the broad principle that drivers can appeal a penalty they believe is wrong remains consistent across London's various charging and enforcement regimes.

What Drivers Should Know

If you regularly use the Blackwall or Silvertown tunnels, there are a few practical steps worth taking before the September change lands:

• Check whether you qualify for a resident discount. TfL operates a reduced rate for people living in the boroughs closest to the crossings, and it's easy to assume you're not eligible without actually checking the criteria.
• Set up an account rather than paying per trip. Registering for an account-based payment system, much like the approach used for the Dartford Crossing's Dart Charge, can make it easier to track spending and avoid missed payments that turn into penalty notices.
• Know your payment window. Missing the cut-off for paying after a crossing is one of the most common ways drivers end up with an unexpected PCN. Mark the deadline clearly if you're not on an automatic payment scheme.
• Watch out for scam texts and emails. Wherever there's a road charging scheme with online payment, fraudsters tend to follow, sending fake "outstanding charge" messages designed to harvest card details. If in doubt, go directly to TfL's official site rather than clicking a link.
• Reconsider your commuting pattern. With rates varying by time of day, some drivers may find it worth adjusting their schedule slightly to travel outside peak hours, or exploring public transport alternatives for at least part of the week.
• Budget for further rises. Given the trajectory of London's other charging schemes, from ULEZ enforcement tightening to congestion charge increases, it would be optimistic to assume September's hike is the last one these tunnels will see.

If you ever receive a PCN linked to these crossings that you believe is wrong, it's worth understanding your right to challenge it rather than simply paying up, though anyone facing a genuinely disputed or complex case should seek independent advice or check TfL's official guidance rather than relying on general commentary.

Looking Ahead

This September's increase is unlikely to be the final word on Blackwall and Silvertown pricing. TfL has shown, through the congestion charge and ULEZ, that charging schemes tend to evolve over time, usually upward, as authorities balance revenue needs against congestion and environmental goals. For drivers in east London, that means the tunnels are likely to become an ongoing, rising cost of daily life rather than a one-off adjustment.

There's also a wider question here about how London, and indeed the UK more broadly, is moving towards a future where driving on specific roads increasingly comes with a direct price tag, whether that's through tunnel charges, workplace parking levies being considered by various UK councils, or clean air zone charges in cities such as Bristol and Manchester. For commuters who have few realistic alternatives to driving, that shift matters enormously, and it's worth keeping an eye on how these schemes develop, both in terms of cost and in terms of your rights if enforcement ever gets it wrong.
