Node 04 — About

Senior counsel, not a leverage model

Oclas is a specialist advisory firm working across the United Kingdom, the Middle East and Africa, operating in the UK since 2005 and Nigeria since 2010. We were founded on a simple observation: the biggest decisions in energy and infrastructure are too often advised by the most junior people in the room.

We work differently. Every engagement is led and delivered by senior practitioners who have run strategy, transformation and delivery inside the sector for clients including supermajors, national programmes and major UK utilities. We take fewer clients, go deeper, and stay accountable for outcomes rather than documents.

Alongside energy and infrastructure, we bring deep experience in business transformation, which means our strategies come with a credible route to execution built in.
