What happens if I submit a subsequent s.73 application?

What happens in the case of unauthorised development?

One of the functions of CIL is to combat unauthorised development. The following applies to any unauthorised development seeking a retrospective permission:

  • The developer loses the right to pay by instalments and the CIL will be due immediately because works have commenced without a valid Commencement Notice being submitted. Under the CIL Regulations, ‘immediately’ means 30 days, after which a surcharge can be applied for late payment;
  • No claims for self-build exemption can be made because such claims have to be submitted and acknowledged before commencement;
  • Surcharges can be applied for failure to submit a valid Commencement Notice;
  • Demolitions cannot be offset against the floor area of the new development because any buildings to be demolished must still be standing when the application is determined.
