Form 1 "Community Infrastructure Levy (Cil) Additional Information" - United Kingdom

What Is CIL Form 1?

Form 1, Community Infrastructure Levy (CIL) Additional Information, is a formal document filled out to determine whether the development must comply with the CIL regulations - the local authorities may have decided to set a charge in the development area, and new sites and dwellings may be liable for the levy or exempt from it. CIL Form 1 is required for all British developers who submit this statement alongside the main planning application.

Alternate Names:

  • CIL Form 1;
  • CIL Additional Information Form.

This form was issued by the Planning Portal under the management of the United Kingdom Ministry of Housing, Communities & Local Government on January 1, 2019, with all previous editions obsolete. Download a fillable CIL Form through the link below.
