Update from Bath and North East Somerset Council:
Clean air zones are being introduced across England so that we can all enjoy cleaner, healthier air.
Please check whether your vehicle will be charged in Bath's Clean Air Zone and pay the charge at www.gov.uk/check-clean-air-zone-charge. All you need is your vehicle registration number.
You can find out everything you need to know about Bath’s CAZ on the BANES website. This includes local exemptions and a financial assistance scheme to help those regularly affected by charges to upgrade their vehicles.
