Cornwall Council validation checklist
Cornwall Local Plan policy 24; the Cornwall and West Devon Mining Landscape WHS overlays much of the west of the county.
Accepted formats
  • One-page Heritage Statement for minor LBC
  • Statement of Heritage Significance for Grade II works
  • Full HIA for WHS-area applications
  • Cornish Studies citation expected
Page-count guidance
No formal limit; conservation officer expects 4 to 12 pages for typical Grade II cases.
Common validation traps
  • Missing reference to the Cornwall and West Devon Mining Landscape WHS where applicable
  • Failure to consult the Cornish Buildings Group guidance
  • Use of non-Cornish slate or non-traditional render

Practical preparation steps

  • Download the LPA's current local validation list before any submission.
  • Read the relevant Conservation Area Appraisal or Statement for the site.
  • Check for any Article 4 directions affecting the site.
  • Where pre-application advice is available, take it , even where charged.
  • Match the accreditation of the author to the asset grade (RIBA-CA or IHBC for Grade II* and Grade I).

Where the LPA's heritage process sits in the planning clock

The LPA's heritage officer is a statutory consultee within the 8-week determination clock for planning permission, the 8-week clock for listed-building consent, and the 16-week clock for major applications. The officer's response is usually written within 21 days of consultation; a strong HIA accelerates that response and reduces the risk of a Regulation 25 further-information request.
