Planning Consultancy Companies in Derby: 28 Active Firms (2026)

Derby has 28 actively trading planning consultancies in this cohort, giving the area a compact advisory base rather than a broad national supplier pool. Reported employment is modest, with 47 people captured across the 11 firms that disclose headcount; that points to owner-managed and small-team practices doing much of the local work. None of the active firms report turnover above £5M, so the cohort is weighted towards specialist practices rather than scaled multi-office consultancies. The recent formation pipeline is present but limited: 4 firms were incorporated since 2022, suggesting some new local entry despite a cyclical applications market.

Planning advice in England is framed by statutory development management, not a sector licence. Local planning authorities determine applications in line with the development plan unless material considerations point elsewhere, so consultants spend much of their time assembling planning statements, coordinating technical reports and managing responses to consultation rather than simply submitting forms. The Town and Country Planning Act and the Planning and Compulsory Purchase Act sit behind that process. Professional conduct is also part of the market structure: the Royal Town Planning Institute limits its public directory to current chartered or legal-associate members and sets conduct expectations for those members.

Derby’s planning-advice market appears likely to remain fragmented, with local knowledge, authority relationships and scheme-type experience carrying weight in vendor selection. Smaller consultancies tend to be useful on discrete residential, commercial and appeal work, while regional multidisciplinary teams are more likely to absorb coordination-heavy briefs involving environmental, transport, heritage and infrastructure inputs. Fee pressure may persist where clients treat planning support as a compliance cost, but complex or contested schemes should continue to reward practices that can manage evidence, consultation and officer engagement carefully. Consolidation looks possible, although the cohort’s small-practice bias suggests gradual absorption rather than a sudden reshaping.
