Follow the CIL process
Stage 6 - relief and disqualifying events
In most cases, this final stage will not be applicable. However, in some circumstances, such as when self build relief has been granted, additional information may be required post issue of any demand notices.
Additionally, If the development was granted relief or an exemption from CIL you may need to tell us about anything that could affect it. Something that would affect your right to receive relief/exemption is called a “disqualifying event.”
A disqualifying event is different for each type of relief or exemption. You can read more about relief, exemptions and disqualifying events on GOV.UKs Planning Practice Guidance
Tell us about a disqualifying event
You must let us know in writing (so by letter or email) about any disqualifying event. You must do this at least 14 days before the disqualifying event will take place. Failure to comply with this could lead to the imposition of surcharges and/or further enforcement action.
After you have let us know about any disqualifying event, we will issue a demand Notice for any CIL that is owed.
