Consultancy Rates
Introduction
Choosing the right consultancy support is an important decision. Providing clear, transparent pricing helps clients understand the value they receive from working with a specialist.
Greg Brock Consulting consultancy rates are structured to reflect the depth of expertise developed over 30 years in aeronautical meteorology at the national and international level. Both hourly and daily engagement pricing models are available, giving clients the flexibility to access targeted technical support or long‑term strategic partnership depending on their needs.
Hourly rates applicable to Tier 1: Essential are are ideal for focused advisory work, technical reviews and short‑duration tasks, while daily rates applicable to Tier 2: Enhanced and Tier 3: Premium provide predictable budgeting for longer-term, multi‑phase projects and organisational transformation.
This dual approach allows clients to benefit from tailored support that fits their operational tempo while maximising the impact of specialist expertise.
"My rates reflect three decades of specialist experience with the UK Met Office, ICAO and WMO, and the ability to provide clear, decision‑ready meteorological and climatological insight. Clients are not purchasing time alone, but access to deep technical expertise, sector-specific knowledge and risk‑informed guidance that supports safer, more efficient and more compliant operations".
