In addition to local CIL, the Mayor of London also has powers to raise CIL. The Mayoral Community Infrastructure Levy (MCIL1) was introduced in 2012 to help finance Crossrail, the major new rail link that would connect central London to Reading and Heathrow in the West and Shenfield and Abbey Wood in the East. The Mayor adopted a new charging schedule MCIL2 to help pay for Crossrail 1 (the Elizabeth Line) and Crossrail 2; it came into effect on 1 April 2019 and superseded MCIL1.

The total Mayoral CIL received in 2024/2025 was £920,130. The largest amount of Mayoral CIL received came from the following developments:

• Land at Thames Road, Crayford - £436,840
• part of Erith Quarry Site, Fraser Road, Erith - £196,369
• Heather Court, 6 Maidstone Road, Sidcup - £52,589
