Businesses in Bristol could face a charge of £400 a year for every parking space under plans being considered this week.
The city council will vote this week on proposals to charge a levy on workplace parking, which would hit businesses with more than 11 spaces.
If the plans are approved, Bristol would become the second city running the scheme. Nottingham has charged £428 for spaces since 2012. Similar plans are being considered in Oxford, Leicester, Glasgow and Edinburgh. The mayor of London has also published guidance to boroughs about introducing charges.
