What they do
Multi-disciplinary national firm with a deep rural-planning bench and an integrated land-agency service. Verified against their published website Carter Jonas Rural as at 21 June 2026.
Fee model
Carter Jonas Rural does not publish a fee scale on its website. Engagement is quote-on-enquiry. We do not infer rates for quote-only firms; ask for a written fee scope before instructing.
When to instruct
- Borderline Class Q where refusal risk is material and an experienced consultant adds win probability.
- Full planning in a sensitive landscape (AONB, Green Belt, listed setting).
- Multi-unit farmstead schemes inside the 10-dwelling / 1,000 m² cap.
When not
- Simple Class Q on a sound single barn in an unrestricted area; a competent local architect may be enough.
- Pure construction-cost questions; that is QS work, not planning consultancy.
