How they reason — coded from their reports

Wilkinson is an almost pure Certificate of Lawfulness/permitted-development specialist (233 of 234 reports carry no 'approve'/'refuse' recommendation label at all, reflecting the CPU/PAEXT decision vocabulary rather than a planning-merits recommendation), and is distinctive for working through the Permitted Development Rights for Householders Technical Guidance clause-by-clause, quoting each numbered sub-condition (e.g. Class B.1(d), Class B.2(c)) verbatim before stating plainly whether it 'has not been confirmed' that the proposal complies -- refusing certificates where any single condition is unconfirmed rather than weighing the scheme overall. She also cross-references a site's own recent planning history (recently granted/refused permissions on the same address) explicitly within the assessment.

Observable habits

· quotes each numbered Permitted Development Rights for Householders Technical Guidance sub-condition (Class A/B/C) verbatim before stating whether it has been confirmed compliant, refusing a certificate on any single unconfirmed condition rather than a holistic assessment

· explicitly cross-references the site's own recent planning history (permissions and refusals on the same address) as a direct input to the current lawfulness assessment

· treats missing supporting detail (e.g. proposed materials not specified) as sufficient on its own to refuse a certificate, rather than requesting further information

What their reports consistently look for

· whether each individual numbered condition of the Permitted Development Rights Technical Guidance (dimensions, materials, window obscuration) has been positively confirmed by the submitted information

· the site's own recent planning history for directly relevant prior permissions or refusals

· whether missing or unclear supporting detail on its own is sufficient grounds to refuse a Certificate of Lawfulness
