PlanningPackPro AI

Deterministic rules engine · England & Wales

Find out what planning route your extension needs before you waste money

Answer a few structured questions and get a plain-English route for your project: Permitted Development, Lawful Development Certificate, Prior Approval, Full Householder Planning Application, or Professional Advice.

No sign-up. No card. No drawings needed for the free check.

Planning drawings, council fees and Planning Portal charges are separate. The free check helps you understand the likely route before you start spending money.

How we're different

  • An answer you can trust. Your route is decided by a fixed rules engine, not AI guesswork — so the figures and rules are right.
  • Paperwork done for you. We write your planning statement, checklist and neighbour letter, locked to your result.
  • We tell you the truth. Complex or borderline cases get sent to a professional — we escalate, we never guess.

What project are you planning?

Pick your project type to start the free 2-minute check.

Extension

Rear, side, wrap-around or two-storey extensions.

Loft conversion

Rear dormers, hip-to-gable and roof-light conversions.

Outbuilding / garden room

Garden offices, studios, gyms and detached outbuildings.

Before you spend money on drawings or council fees

Planning drawings and council application fees can cost significantly more than the document pack. PlanningPackPro helps you understand the likely route first, so you do not start by submitting the wrong type of application.
