FOI001761 Planning/CIL

I am writing to request information under the Freedom of Information Act 2000 regarding the Community Infrastructure Levy (CIL) which I understand your Council operates.
Please can you provide the following information:
1. Does the Council exercise discretion if genuine homeowners developing their own homes for personal use (such as extensions, annex, self-build) have unintentionally submitted a form late (e.g. an exemption form or commencement notice), does the Council not charge the full levy?
2. If so, please provide:
•    Any internal policy, guidance, or precedent the council refers to in such cases.
•    Only if possible and easy to ascertain: the number of instances over the past five years where the council has waived or reduced the CIL charge due to late form submission in these cases.
