Stage 1 remapping in Barnet
Barnet sits 7th of the 104 largest towns we cover for plug-in cars, which make up 9% of the 130,542 privately kept cars in the council area. Diesel, at 12.4%, is one of the lowest shares in the same group. Both figures are for the end of June 2026. If yours is one of the diesels still on Barnet's roads, a Stage 1 remap changes how it drives, not what it runs on. The engine's settings are adjusted in software, inside its limits, and the extra mid-range torque shows when you overtake or join a fast road. Any change in fuel use depends on how you drive, so treat it as a side effect, not the reason.

Driving in and around Barnet
The M1, A1, A41 and A406 are among Barnet's main roads. London Gateway Services on the M1 is 4.4 km away and South Mimms on the A1(M) is 8.2 km, so a run out of London starts close by. In the 2021 Census, 25.1% of working residents in the Barnet council area drove to work, against 45.1% across England and Wales, and 29.9% of households had no car. In 2025 MOT tests across NW postcodes, the Mercedes-Benz E Class was the most tested diesel car and the Ford Transit the most tested diesel van. The ULEZ covers every London borough, and its daily charge can apply to cars and vans. A remap does not change a vehicle's emissions standard, so it does not change whether that charge applies.
