Park near the door in Supermarkets, nearly always guaranteed a space.

Also Where the Blue Badge Scheme applies:

• you are allowed to park at on-street parking meters and pay-and-displays free of charge (unless there is a local traffic order in force specifying a time limit)

• you may be exempted from parking time limits imposed on other road users

• in England and Wales, you may usually park on double or single yellow lines for up to three hours

• there is no time limit on parking in Scotland unless there is a ban on loading and unloading

• you will need to display the special blue parking disk displaying the time of arrival in addition to the Blue Badge. If you run up your time limit, you cannot renew it immediately on the same road or part of a road, but must allow an interval of at least one hour.
• The badges can be used while travelling abroad within the European Union (EU) and in some other European countries. The Blue Badge scheme does not apply to off-street car parks, private roads or at most airports.
