Up to 10 local authorities could be planning to introduce workplace charging levies, which could cost employees up to £1,000 per year to park at work. According to The AA, Hounslow Council is proposing to introduce a charge between £500 and £1,000 and nine other councils are considering similar measures. The schemes are designed to reduce inner-city emissions and improve air quality by discouraging drivers from using their car to get to work.
