don't want to burst your bubble but:
"The Low Emission Zone (LEZ) operates 24 hours a day, every day of the year, including weekends and public and Bank Holidays.
Charging days run from midnight to midnight. So if you were to drive within the LEZ between 11.30pm and 01.00am the next day, you'd need to pay for two days.
Vehicles parked in the zone but not driving are not subject to the LEZ requirements for that day.
Remember, the LEZ isn't the same as the central London Congestion Charging zone. The Congestion Charge applies 7:00am to 6:00pm Monday-Friday, excluding public and Bank Holidays. If you drive within the Congestion Charging zone during these times you will have to pay the Congestion Charge, even if you meet the LEZ emissions standards or have paid the LEZ daily charge."
