Community Infrastructure Levy (CIL)

The Community Infrastructure Levy (CIL) is a charge that local authorities can set on new developments. It raises funds for infrastructure, like schools.

View the charging schedules of Southwark's CIL and the Mayor of London's CIL, which we also collect.

We can charge for the same infrastructure using both CIL and S106 fees.

Southwark CIL spending is split between: 

• 70% for borough-wide infrastructure, such as major projects like the Elephant and Castle roundabout and the Bakerloo tube line extension
• 25% for local community areas and projects
• 5% to run the CIL

Read our infrastructure funding statements for more about Southwark CILs.

Liability for CIL starts as soon as planning permission is granted. View the standard CIL process flow chart (para.120 of CIL PPG).
