Sadiq Khan has been urged not to increase the London Congestion Charge, which could see driving bills increase by more than £40 daily.

Conservative MP Louie French for Old Bexley and Sidcup has warned that the upcoming hike in fees from £15 to £18 would have a "disproportionate impact" on constituents who rely on London roads for work.

The MP has now written to the London Mayor calling on him to reverse the decision to increase the Congestion Charge before it's too late.

French detailed how the Congestion Charge increase, on top of Labour's already planned hikes to the Dartford Crossing, coupled with the £15 Ulez charge and new Silvertown and Blackwall Tunnel fees of up to £10, would put more pressure on working people.

The London Mayor plans on increasing the road charge from January 2, 2026

The letter detailed: "I am writing to formally oppose your plan to increase the Congestion Charge by 20 per cent, affecting 140,000 drivers every day. This is yet another unaffordable tax raid on working people.

"As you know, many Londoners rely on their vehicles to travel in our city, even in central London, where public transport serves most people.

"If you are a tradesperson, disabled, elderly, the parent of a young child, or driving sick relatives to the hospital, you may need to drive in central London. These are the people you wish to launch a fresh highway robbery against."

French explained how this is the second time the London Mayor has increased the Congestion Charge, with it previously costing £11.50 a day in 2016, with it is now set to increase by 56 per cent to £18.

The Dartford Crossing will increase its fees by 40 per cent on September 1

Changes to the Congestion Charge follow a consultation process which concluded this week, with TfL now looking through feedback before deciding to introduce the higher fee on January 2, 2026.

On top of increasing the fee, TfL also revealed plans to axe the exemption for electric vehicles, which will no longer apply from December 25.

This move has led to increased fury among the professional driving community, which has made significant progress in purchasing electric vehicles in recent years.

The GMB Union, which represents workers, shared on X: "GMB stands with electric delivery drivers hit by a punitive new congestion charge. Drivers who switched to EVs, believing they'd avoid the charge, may now face thousands of pounds in extra costs annually."

The union called the decision "unconscionable", with it punishing drivers who "did the right thing" by switching to electric, "hitting them with thousands in new costs and risking financial ruin".

French also warned that this year alone, drivers will face the steepest increases in driving charges, starting with the Dart Charge at the Dartford Crossing, which is due to increase by 40 per cent on September 1 to £3.50 per crossing.

"This further adds to the pressure on working people reliant on driving in our city, especially those living in South East London, who face heavy tolls to cross the river," French stated.

The Conservative MP explained that Bexley motorists have "never paid more to City Hall" and are "receiving nothing in return".

The Congestion Charge was increased by the London Mayor in 2016

French claimed that Transport for London had been cutting its contribution to road maintenance in Bexley and "ignored residents' calls" for improved bus routes.

This also included stopping the SL3 at Bexley Village, and "repeatedly rejected pleas" for the DLR and Elizabeth Line to be extended further into the borough.

The letter added: "As Mayor, there's not one road charge that you have not chosen to expand, hike, or impose against people's wishes.

"This will be your legacy when you finally leave City Hall, alongside overseeing record increases in crime that have made London less safe for businesses, residents and visitors."
