What LAB Energy Advisors does

LAB Energy Advisors is an independent, specialist energy advisory firm headquartered in London, founded in May 2021 by Mark Llamas and Paul Bannister. The firm provides M&A and Asset & Divestment (A&D) advisory services across the upstream oil and gas sector, renewables (including geothermal and offshore wind), and energy transition technologies (hydrogen, carbon capture), covering corporate M&A support, production divestments, development sales, exploration farm-outs, and buyside mandates. Its core London team consists of technically trained geoscientists and engineers—several with prior tenures at majors such as Shell, CNOOC, and Carnarvon Petroleum—supplemented by a global network of regional advisors spanning North America, South America, Asia, and Australia.

The service offering is differentiated from bulge-bracket and larger boutique competitors by its independent, conflict-free positioning and its technical bench, which enables credible engagement with operating boards on subsurface, asset-quality, and development-stage transactions rather than purely financial-structuring work. The firm has executed mandates for a broad set of small-to-mid cap energy issuers, including Hartshead Resources, Rhino Resources, Chariot Energy, ADX Energy, Repsol Sinopec, Adamantine Energy, MCF Energy, and Cool Planet Technologies, and has extended into capital raising advisory for cleantech clients.

LAB Energy Advisors monetizes exclusively through transaction-based advisory fees on closed mandates, with go-to-market driven by direct, relationship-based engagement at board and executive management levels. The firm is privately held and founder-led, with no disclosed external funding rounds. Operational signals—including a 2023 relocation to larger Bloomsbury premises and a 2023 senior promotion—indicate ongoing capacity scaling, while partnerships with Green Angel Syndicate, Green Angel Ventures, and Aegir Insights extend its reach into UK cleantech deal flow and offshore wind intelligence without proportional headcost.
