About us

Llewellyn Consulting is an independent economics advisory firm, based in the City of London. We provide high-level bespoke services to a strictly-limited number of clients. We specialise in macroeconomic, policy, and political issues. We look at macroeconomics in the broad, from the top-down, with a particular emphasis on policy, so as to determine the economic and market implications that flow not only from contemporary events, but also from longer-term drivers. 

We operate with a core team and an extensive network of associates, recognised experts, and strategic business partners, who work with us project-by-project. We are thereby responsive, and able to accommodate diverse concurrent projects. 

We communicate in plain clear English, aiming at the highest levels of clarity and precision. We take full responsibility for the quality of our output. We are used to working with in-house teams, and set the highest store by total trust, discretion and confidentiality.
