Blue Badge holders have been warned they face fines - because holding one does not mean free parking. The City of London has its own disabled parking scheme and motorists could find themselves falling foul of the rules and regulations in the capital.

In the City of London, the scheme is not “fully operational” with only 200 free bays available for Blue Badge holders. Drivers must display the clock and the Blue Badge so that the serial number, expiry date and the issuing authority are clearly displayed.

If a badge is incorrectly displayed or in a “non-authorised area”, it may result in a parking fine or a penalty charge notice. The council explained: "The Blue Badge scheme does not fully apply in the City of London but we do provide allocated parking in the Square Mile for people with disabilities and the City of London Corporation runs its own Red Badge parking concession scheme, valid only in the City of London, for people with disabilities who are permanent workers in the City or City residents."

Over 200 bays are available for free, provided the badge and clock are displayed. These can be used for four hours on weekdays. Around St Bartholomew's Hospital the bays can be used for six hours on weekdays. Check the bay time plate for information. There is no time limit at the weekend.

Blue Badge holders can park for an extra hour, for free, at payment parking bays after the expiry of purchased time. Holders cannot park in a suspended bay or on single or double yellow lines or where there is a loading restriction indicated by yellow chevrons on the kerb stone.

Motorists also cannot park on the pavement or footway, in a bus lane, in a bay reserved for specific users (eg a doctor's bay) or where there is a dropped kerb or raised carriageway.
