Lewisham is looking at the MPA's strategy, planning for external and internal comms, as well as resources and online comms and marketing.
It will identify ways the MPA can develop its comms in light of changing priorities, such as the growing focus on community engagement.
MPA director of comms Peter Powell said: 'It is a good thing to be able to share the way we do things. There have been a number of reviews over the past seven years, but this is very welcome as it is a detailed look at procedures.'
The MPA oversees the Metropolitan Police Service, the largest police force in the UK. It exists to make sure that London's police force is accountable for the services it provides to people in the capital.
The review is intended to provide a 'broad brush' report outlining areas for further development by early May. It forms part of a wider improvement programme being implemented by the MPA.
Lewisham is conducting the review free of charge and did not pitch for it.
