Location search and permission (if needed)

Some of the locations that we are going to use are public places so we will need to get permission to use them. One of these locations is Crystal Palace Station. This is because well will need to use it during a busy period and they would have to alert the public of the recording. Another location are going to use is Tower Bridge. For this we will not need permission and we may not be in Tower Bridge but in the surrounding area and get shots of it in.
