Wrong Fuel London FAQs

How quickly can you reach me in London?

Our average arrival time is 46 minutes, and we aim to have you back on the road within 90 minutes of your call. We hold mobile units right across the capital, so a technician is rarely far away — day or night. Traffic and access permitting, central London jobs are often reached faster because of the density of our coverage.

Do you charge extra for the ULEZ or Congestion Charge zone?

No. Our technicians carry ULEZ-compliant and Congestion Charge–ready vehicles, and we do not add a surcharge for attending callouts inside the ULEZ or Congestion Charge area. We can access central London zones directly, including TfL Restricted Roads and Red Routes, without extra charge or delay.

I’ve put petrol in my diesel on a London forecourt — should I drive off?

No — please don’t start the engine if you haven’t already. Running a diesel engine on petrol circulates the contaminated fuel through the high-pressure injection system and can cause damage costing thousands to repair. Stay where you are, move the car to a safe spot if you can, and call us. We come to the forecourt or roadside.

Do you cover all London postcodes?

Yes — we cover every central and inner London postcode district, from EC and WC through the N, E, SE, SW, W and NW areas, as well as the wider Greater London boroughs. Across London as a whole, CR0 (Croydon) is our busiest postcode with 94 cases in 2024–25.

Do you handle AdBlue put into a diesel tank?

Yes — and it’s especially common in the capital. London has the highest AdBlue contamination rate of any UK region at 12.8% of callouts, close to double the national average, driven by the city’s large fleet of modern executive and lease diesels. AdBlue needs removing quickly because it attacks fuel lines, seals and injectors. Don’t start the engine — call us and we’ll drain and flush the system.

Do you cover Heathrow and London City airports?

Yes. Drivers misfuelling shortly after collecting a hire car are one of the most established causes of callouts near the airports, and we cover the approach zones for Heathrow (UB3), London City (E16) and the wider Greater London airport corridors. Our technicians are experienced in accessing the Heathrow perimeter area.

My car is at home in London — can you still come?

Yes. Driveway, residential street and car-park callouts are completely standard. We don’t need garage access — our equipment is fully mobile, and we drain and dispose of the contaminated fuel on site. The car can be back on the road within an hour of our arrival in most cases.

Will draining the fuel void my manufacturer’s warranty?

No. A professional fuel drain by a trained technician using sealed disposal equipment is the manufacturer-recommended response to misfuelling. Driving the car on the wrong fuel, on the other hand, can void warranty coverage on the fuel system, injectors and DPF — which is why acting quickly matters.

Key Facts:

Fuel Fixer handled 4,459 fuel drain cases across London in 2024 and 2025 — making London the 4th largest market in Fuel Fixer’s entire national dataset, behind the South East, South West and North West regions.
Mercedes is London’s most commonly misfuelled make with 649 wrong fuel cases — the only region in the UK where Mercedes outranks Volkswagen. This reflects the capital’s extraordinary concentration of executive and corporate lease cars in the financial and professional services sectors.
London has the highest AdBlue contamination rate of any UK region at 12.8% — nearly double the national average of 8.5%. Almost 1 in 8 London fuel drain callouts involves AdBlue rather than wrong fuel.
London’s wrong fuel rate of 81.1% is the lowest of any UK region — the consequence of the high AdBlue and commercial drain case mix that is unique to the capital.
KT15 (Addlestone, on the Surrey border near the M25) achieves the fastest drain time in the London zone at 26 minutes, and TW (Twickenham and Richmond) is the fastest broad sub-area at a 29-minute median — among the fastest of any London postcode area.

And Also:

The City of London and Canary Wharf together represent the UK’s most concentrated corporate lease car zone — thousands of company cars and pool vehicles are in daily use by financial-sector workers across EC, E14 and the surrounding postcodes.
London’s ULEZ (Ultra Low Emission Zone) — expanded in August 2023 to cover the entire area within the North and South Circular roads — has accelerated the replacement of older diesel vehicles in the capital. This is why London’s per-capita wrong fuel rate is lower than the national average: the diesel parc is declining faster in London than anywhere else in the UK.
Our technicians carry ULEZ-compliant and Congestion Charge zone vehicles — we can access central London zones directly, without surcharge or delay, including TfL Restricted Roads and Red Routes. We do not charge extra for attending callouts within the ULEZ or Congestion Charge area.
Five major airports serve the Greater London travel zone: Heathrow (UB3), Gatwick (Surrey), London City (E16), Luton (LU) and Stansted (CM) — all contributing hire-car misfuel traffic. Fuel Fixer covers all five airport approach zones.
