Policing queries

Find out about the Mayor's role for policing in London.

The Mayor is not able to intervene directly in complaints or comments about specific incidents involving the police. These need to be directed as below. 

If you have a general enquiry or comment about policing in your local area or London-wide, you should contact the Metropolitan Police Service (MPS). Details on how to contact them can be found on their website.

If you have a complaint about specific incidents with the police, you should make a complaint to the Metropolitan Police Service (MPS) so they can carry out a local investigation.

You can raise a complaint with the MPS online

Alternatively, you can write to the Directorate of Professional Standards (DPA) at:
DPS Complaints and Satisfaction Team
22nd Floor, Empress State Building
Lillie Road

To make a complaint by telephone, you should call 101 for the Central Communications Command, where a call handler will take the details of your complaint. Textrelay no: 18001 is available for deaf and hard of hearing people.

If you are unhappy with the response from the MPS, or you need to make your complaint to an independent organisation, you should contact the Independent Police Complaints Commission (IPCC). You can contact them online or by post to:

Air quality

The Mayor, Sadiq Khan is tackling London's acute air pollution. You can find out what is being done to improve air quality in London.

Garden Bridge

The Mayor of London, Sadiq Khan, has announced the GLA will not be providing Mayoral guarantees for the Garden Bridge project.

The Mayor has said:  ‘Under the previous Mayor, a considerable amount of London taxpayers’ money has already been spent on the Garden Bridge. Having assessed all the information available to me, my view is that providing Mayoral guarantees will expose the London taxpayer to too much additional financial risk.’

The Mayor's role in housing involves setting priorities through London's Housing Strategy and directing and managing investment in new affordable housing. 

However, he does not have the legal powers to help individuals with housing issues. 

The manifesto the Mayor published when campaigning for election makes clear his concern about overcrowding because of the shortage of decent and affordable homes faced by Londoners. His manifesto also set out his commitment to building the homes London needs, with a target of half of all the new homes built across the city being genuinely affordable.

You will need to contact your local council to discuss your housing issue.
